Streszczenie:

Lighting is one of the important reasons of transmission line trip accident. For 330kV and above ultra high voltage transmission line, lighting flashover more frequently occur. To reduce tripping rate effectively and fundamentally, lightning over voltage level should be analyzed besides anti-pollution flashover. In this paper, a simplified equivalent circuit model of a 330kV overhead transmission lines is established. The lightning over voltage of the transmission is analyzed and calculated. Method to reduce the lightning overvoltage is discussed.

This study, aimed to determine the effects of different light regimen and day/night feeding on some performance criteria of 1104 broiler chickens during summer season. At the beginning of second week they were separated according to their sexes, and experiment had 2 × 6 replications. The 1st group, as control, received continuous lighting (daylight + lightening during night) and fed ad-libitum. The 2nd group was treated with continuous lighting too, but they had no access to feed between10:00 and 16:00 o’clock during the last three weeks. The 3rd group was also exposed to continuous lighting but had no access to feed between10:00 am and 16:00 pm. Fourth group received continuous lighting but had no access to feed between 24:00 pm and 06:00 am. Fifth group received continuous lighting, but they were not fed between 24:00 pm and 06:00 am during the last three weeks of experimental process. Sixth group had no access to feed box during 24:00 pm and 06:00 am, when they had not been exposed to light as well. There were no notable differences in live weight gain of male and female birds for all treatment groups, and similarly differences among feed consumption and feed conversion ratios were not remarkable statistically regardless of the sexes of chickens. There were significant differences in hot-cold carcass yields of the 3rd and 6th treatment groups for male birds and 6th treatment group for female birds. The differences for carcass weights of male birds were statistically significant and 3rd and 6th treatments groups were tend to be relatively higher than the other treatment groups. The differences among treatment groups for carcass weights of female birds, however, were not significant and similarly the effects of the treatments on the mortality rate was found to be in significant for same birds. Lightning (24h) and feeding ad - libitum affected the performance of the birds adversely, whilst restricted feeding and lightning process reduced the yield-loss the animals during the summer season.

With the rapid development of urbanization and the power system, the damages for the power system and electrical equipments which due to lighting strike are increasing. As the distributions of lighting activity are regional and random, the requirements for electrical and electronic equipment, voltage and insulation level are varied from lighting activity in different regions. This paper adopts the Lightning Location Data on the Pearl River Delta in the last 10 years, and uses the method of probability statistics to analyze the regional ground flash density, the probability of lightning strike accident, the damages of the lightning strikes accidents and other risk factors. It takes the topography, regional features, population density and other factors into account, and uses the weighted scores to establish the risk assessment model for the lightning strikes, programs to achieve the automatic calculation in allusion to the risk of lightning strikes in different types of buildings and insulation levels of the electrical and electronic equipment, and assess the risk of lightning strikes on the electrical and electronic equipment. And based on the risk assessment result, it incorporates the installation location, characteristics, importance and other factors to study the electronic equipment withstand voltage and insulation level.

In this paper, the simulation of ±800kV UHVDC transmission line in which fault lightning stroke and non-fault lightning stroke, line short circuit occur shows: because there is fault current lumped parameter access to earth during the fault lightning stroke or ground fault, the voltage waveform decrease suddenly and cross repeatedly the zero line in 5ms time window；There is no fault current accessing to earth during non-fault lighting stroke, the disturbance caused by lightning is too less than value of the pole voltage. The voltage waveform comes from the protect position change up and down around the direct voltage line and decays to the pole voltage line in the 5ms time window at last. In the case of the fault lightning or ground fault non-lightning, the correlation degree of transient component and pole voltage line in the time window is little. On the contrary, it is large during the non-fault lighting. Above this, the correlation degree is calculated using 5ms samples. This kind of algorithm can resist random noise effectively,calculating speed is very fast. Many PSCAD simulations show that the algorithm can identify lighting disturbance correctly.

<p> A lightning strike could bring thousands mega-ampere of current in a blink of eyes. As a result, a failure of grounding the strike may cause serious damage to the home and industrial appliances and gadgets. Hence, a lightning protection system is essential to the current transmission system. Lighting is a natural phenomenon that is unavoidable. Hence, the study of the properties and characteristics of lightning is a must in designing lighting protection system. Every application has different criteria to be fulfilled. The type of lighting protection system is categorized based on the location and user. The different of location is a public area, transportation system, power system transmission and generation system which include renewable energy source. Each area can conclude different level of protection. This paper is assessing the possibility and probability of transient impact on all applications including, public area, power system line, and generating system. The review includes countermeasure which addressed few steps to determine the effect of lightning and countermeasure of protection.</p>

Lightning fires are not considered an important problem in Europe, especially in the Mediterranean region, where lightning is a minor cause of fire. On the southern slopes of the Alps,however, lighting fires are common enough during the summer months to cause relevant costs for their control. In this contribution, we discuss some general features concerning the lighting-generating thunderstorms, starting of the fire, fire behaviour and fire extinction, especially in the valley Aosta(Italy) and in the Canton Ticino (Switzerland).

As issues of environment and energy draw keen interest around the globe due to such problems as global warming and the energy crisis, LED with high optical efficiency is brought to the fore as the next generation lighting. In addition, as the national income level gets higher and life expectancy is extended, interest in the enhancement of life quality is increasing. Accordingly, the trend of lightings is changing from mere adjustment of light intensity to system lighting in order to enhance the quality of one’s life as well as reduce energy consumption. Thus, this study aims to design LED context lighting system that automatically recognizes the location and acts of a user in residential areas and creates an appropriate lighting environment. The proposed system designed in this study includes three types of processing: first, the creation of a lighting environment index suitable for the user’s surroundings and lighting control scenarios and second, it measures and analyzes the optical characteristics that change depending on the dimming control of lighting and applies them to the index. Lastly, it adopts PIR, piezoelectric, and power sensor to grasp the location and acts of the user and create a lighting environment suitable for the current context.

The Internet of Things (IoT) is rapidly growing and is starting to be incorporated into commercial buildings. One of the ways that the IoT is being used in buildings is connected lighting, also referred to as smart lighting. Connected lighting allows for communication between the lighting system, people, the environment, and other devices. This paper will focus on connected lighting and its effect on lighting controls and design. The IoT is expected to see substantial growth in the next few years and the growth of connected devices will have a huge impact on the lighting industry as connected lighting systems will be installed in more commercial buildings. The shift to solid state lighting (SSL) in recent years has brought the transition from conventional lighting controls to connected lighting controls. For this shift to be successful, issues with interoperability, security and reliability will need to be overcome. Connected lighting systems on the market are using both wired and wireless technologies. Power over Ethernet (PoE) and wireless technologies such as ZigBee and Bluetooth Smart are currently being incorporated into connected lighting systems. The introduction of these technologies is changing the way that lighting control systems are designed and installed. Products such as fixture-integrated sensors and wireless devices are also being used in connected lighting systems. These products, along with the wired and wireless technologies, are changing lighting control system configurations. Lighting design will also be affected by connected lighting systems. New features including color-tunability and indoor positioning will be used to enhance the lighting system and improve occupant health. Also, energy code compliance will be easier since connected lighting controls will be mostly software-based and can be reprogrammed. Connected lighting systems will be integrated into other building systems such as heating, ventilating, and air conditioning systems or security systems and will also be used in a variety of applications. Connected lighting systems will greatly affect both lighting controls and design of lighting control systems. This paper introduces connected lighting and is intended for those who are not familiar with its design, applications, and implementation.

Streszczenie:

Road lighting is widely recognised as an efficient traffic safety measure. However, we know too little about the effect of road lighting on accidents in a given situation and we do not know what kind of lighting that is optimal for the situation. Society today has a demand for energy savings, locally and globally, and we should not use more energy for road lighting than is necessary. In the field of road lighting the demand for energy savings is accompanied by a fast development of techniques and equipment that give great opportunities for energy savings. The opportunity already exists to adapt the lighting to the actual road, traffic and weather situation. It is a problem, however, that we do not know what lighting quantity and quality which gives the best benefit – cost ratio. The objective of this thesis is to contribute to more knowledge about the relationship between road lighting and traffic safety and thus make a basis for benefit – cost calculations (including environmental costs). The thesis is based on four studies about the safety effect of road lighting, reported in four papers. The first is a literature study, the second is a Norwegian before-and-after study, the third is a cross-section study of Dutch accidents and the fourth is a study of Dutch motorway accidents. The thesis also contains three appendices presenting some more details from the studies than were shown in the papers. The content of the four papers are presented and discussed as a whole in a (fairly comprehensive) introductory part consisting of 10 chapters, where conclusions about the safety effect are discussed and summarised. The thesis in addition discusses the benefit – cost ratio of road lighting, but it is not treated in any of the papers. It has been useful to discuss this matter in advance of the discussion of the future role of road lighting. In the literature study (Paper I), the mean effect of road lighting on injury accidents during darkness was found to be -30 %. The mean effect on fatal accidents was -60 %. The mean effect on pedestrian injury accidents was -45 %, and on motorways the mean effect on injury accidents was -50 %. In the Norwegian before-and-after study (Paper II), the estimated effect of road lighting on injury accidents during darkness was -28 %. The estimated effect was larger at high speed limits than at low speed limits. The estimated effect was smaller on roads with AADT (average daily traffic volume) > 8000 vehicles than on roads with AADT < 8000 vehicles. In the cross-section study of accidents on all Dutch roads (Paper III), the mean effect of road lighting on injury accidents during darkness was found to be -50 %, while it was -54 % when only rural roads were considered. The effect on pedestrian, bicycle and moped accidents was larger than the effect on automobile and motorcycle accidents, and the differences were statistically significant. There was no significant difference between the safety effects for different accident types (Rear end collisions, Frontal collisions etc.) and no significant difference between the driver age groups 60 – 74 years and 30 – 39 years. The effect on fatal accidents was found to be slightly larger than the effect on injury accidents. The mean effect on twilight accidents was 2/3 of the effect during darkness. In the study of motorway accidents (Paper IV), the effect on injury accidents during darkness was found to be -49 % on Dutch motorways, while the effect seemed to be much smaller on British and Swedish motorways. On Dutch rural roads and Dutch motorways, the estimated effect of road lighting on accidents during darkness was smaller during adverse weather and road surface conditions than in fine weather and dry surface conditions. The differences were statistically significant. In fog, there was found no effect of road lighting during darkness. However, there were indications on a daylight safety effect during fog, possibly due to guidance from light poles. The results from the studies described in this thesis give a basis for increasing the application of road lighting as a traffic safety measure worldwide. Cost – benefit calculations indicate that road lighting is one of the most efficient road safety measures available. However, the energy consumption related to road lighting is a problem that must be considered. The great challenge is to reduce the energy consumption as much as possible without reducing the safety benefit too much. Future road lighting will probably be of the adaptive type, and it will be essential to know how the safety effect varies according to traffic and weather conditions and how it varies with the road lighting level and the quality of the lighting. The thesis answers some question about the safety effect during different weather conditions. There is, however, too little information about safety effect related to varying road and traffic conditions. A more serious lack of knowledge is that we do not know how the safety effect varies according to the lighting level. It is not possible to balance the energy consumption and the safety effect as long as this relationship is not known.

In this thesis I study the role of artificial lighting in the everyday urban life of older residents living in the London Borough of Newham. Newham's light infrastructure is currently undergoing change as the borough's entire 19,000 street lamps are being re-placed with Light Emitting Diodes and as a range of regeneration projects provide public spaces designed with new lighting. By increasing visibility and encouraging everyday activity into the evening, the Council claims that the changes in public light-ing will provide 'eyes on the streets' and encourage 'eyes from the windows' of build-ings, contributing to increasing 'natural surveillance'. The Council's avowal of every-day practices in streets and in homes, has made me question how lighting affects the way older residents move through streets and carry out domestic practices as dark-ness falls. The study explores how light planning, lighting design and everyday, rou-tine practices in the public realm and inside homes co-produce the urban, lit environ-ment. Two major contributions of the thesis lie in the (post)phenomenological ap-proach I develop to study everyday experiences of urban lighting, and the methodo-logical framework I employ to research such practices, which combines mobile and visual methods. I have conducted 11 in-depth interviews with nine different planners and designers, 12 walk-along interviews with 22 residents between 58 and 79 years old, and a collaborative photography project with 14 residents between 68 and 96 years old. As I show how older residents experiences different lighting technologies, layers of light, and different lit spaces in their neighbourhoods, I discuss how urban lighting makes them see, feel and carry out routine practices in particular ways. Based on my findings, I argue that urban lighting shapes what, and how, people see, but how people see depends on how they negotiate changes in lighting. In a range of examples where residents mould the urban, lit environment or respond to lighting in different ways, I show how they play and active part in co-producing ways of seeing. I argue it is crucial that light planners and lighting designers recognise such co-constitutive role of everyday practices in order to ensure better lighting for our future cities.

Lighting, and its emergence as a digital and networked medium, represents an ideal platform for conducting research on both sensor and human-derived methods of control. Notably, solid-state lighting makes possible the control of the intensity, spatial, and color attributes of lighting in real-time. This technology provides an excellent opportunity to conduct new experiments designed to study how we perceive, judge, and subsequently control illumination. For example, given the near-infinite variation of possible lighting attributes, how might one design an intuitive control system? Moreover, how can one reconcile the objective nature of sensor-based controls with the subjective impressions of humans? How might this approach guide the design of lighting controls and ultimately guide the design of lighting itself? These questions are asked with the benefit of hindsight. Simple control schemes using sliders, knobs, dials, and motion sensors currently in use fail to anticipate human understanding of the controls and the possible effects that changes in illumination will have upon us. In this work, the problem of how humans interact with this new lighting medium is cast as a human-computer interaction. I describe the design and validation of a natural interface for lighting by abstracting the manifold lighting parameters into a simpler set of controls. Conceptually, this "simpler set" is predicated on the theory that we are capable of discerning the similarities and differences between lighting arrangements (scenes). I hypothesize that this natural ordering (a metric space in a latent multidimensional basis) can be quantitatively extracted and analyzed. First, in a series of controlled experiments, I show how one can derive this mapping and I demonstrate, using empirical evidence, how future sensor networks will eventually emulate our subjective impressions of lighting. Second, using data obtained in a user-study, I quantitatively derive performance estimates of my proposed lighting user interface, and statistically contrast these performance results with those obtained using a traditional interface comprised of sliders and buttons. I demonstrate that my approach enables the user to attain their illumination goals while substantially reducing task-time and fatigue.

Tese de Doutoramento para obtenção do grau de Doutor em Design, apresentada na Universidade de Lisboa - Faculdade de Arquitetura.
A iluminação pública alterou profundamente a nossa percepção e uso do espaço urbano nocturno. Compreendida muitas vezes apenas como uma questão técnica em vez de humana, é baseada principalmente no desempenho fotométrico da visão, deixando de fora outras dimensões humanas, como a psicologia da percepção. Actualmente, a iluminação pública está particularmente direccionada para a redução do consumo energético através do uso de novas tecnologias, tal como iluminação adaptativa e fontes de luz LED e o uso de soluções de iluminação standardizados. Neste contexto surge a oportunidade para o desenvolvimento de novas abordagens à iluminação que tirem partido da flexibilidade inerente destes sistemas, melhorando a relação entre o bem-estar do utilizador e o consumo de energia, contribuindo assim para uma prática de design mais sustentável. Com base numa abordagem research through design, foi utilizada uma metodologia mista, de natureza não intervencionista e intervencionista. A partir de uma inicial revisão bibliográfica e da experiência profissional do investigador, considerou-se que adaptabilidade é um importante factor técnico e de design para a melhoria da iluminação pública. Propondo o desenvolvimento de um método orientado para o utilizador, que determine os cenários de iluminação adaptativa para a condição mais adequado e mínima aceitável, considerando uma relação utilizador-espaço específica, com base na percepção de bem-estar do utilizador e a avaliação da qualidade dos cenários configurados. Para apoiar a implementação do método foi desenvolvido um quadro de referência - Continuidade de Luminância Percepcionada como forma de descrever o comportamento da iluminação adaptativa. A informação reunida - objectiva e subjectiva - fornece uma base empírica para que profissionais da iluminação possam criar soluções personalizadas para um contexto físico e humano. Foi formulada a hipótese de investigação que o método proposto, potencia a criação de soluções de iluminação mais ajustadas e flexíveis. Permitindo a adequação de normas suportada em dados objectivos para uma relação utilizador-espaço específica. Dando uma resposta efectiva ao nível do bem-estar do utilizador e da gestão energética, promovendo uma prática de design mais sustentável e melhorando a experiência nocturna. Para testar a hipótese foi executada uma experiência em espaço real como um primeiro caso de estudo na vila de Arraiolos, Portugal. Uma segunda experiência foi realizada com o objectivo de testar a consistência dos dados prévios e confirmar a hipótese primária. Após a análise e validação estatística dos dados recolhidos, foi possível afirmar que a tendência de escolha em ambas as experiências foi muito semelhante, significando que os cenários de iluminação inicialmente considerados como adequados eram reais e significativs, proporcinando elevado nível de apreciação da qualidade da luz. Significa igualmente que existe uma relação entre a configuração da iluminação, distância de visibilidade e a ilusão perceptiva de que um espaço está totalmente iluminado. Mostrou-se ainda que a maioria dos participantes aceitaria iluminação pública adaptativa como prática comum dentro do quadro de referência da Continuidade de Luminância Percepcionada. Com base nos resultados, concluiu-se que o método proposto é uma ferramenta de design válida na concepção de soluções de iluminação pública adaptáveis, confirmando a hipótese primária e secundárias, demonstrando a sua relevância para uma prática de design de iluminação mais sustentável e a melhoria da sustentabilidade do espaço urbano nocturno.
ABSTRACT: Public lighting altered profoundly the way we perceive and use nighttime urban space. It often is understood only as a technical issue rather than a human one, mostly based on photometric visual performance, leaving mostly out other human dimensions such as the psychological perception of light. Currently, public lighting is predominately directed to reducing energy consumption by means of the use of new technologies, such as adaptive lighting and LED light sources and the use of standardized lighting schemes. In this context, there is an opportunity to develop new lighting approaches that take advantage of the inherent flexibility of these systems to improve the relationship between user's well-being and energy management, contributing to a more sustainable design practice. Based on a research-through-design approach, a mixed methodology was used with a non-interventionist and interventionist nature. From literature review and professional experience, we considered that adaptability was an important technological and design factor to improve public lighting. Proposing the development of a user-oriented method that determines adaptive lighting scenarios for the most adequate and minimum acceptable lighting condition, for a specific user-space relationship, based on the user’s perception of well-being and the assessment of the perceived lighting quality of the scenarios. To support the implementation of the method, the Perceived Luminance Continuity framework was developed as a way to describe the adaptive lighting behaviour pattern. The gathered data - objective and subjective - provide an empirical basis for lighting professionals to design customized solutions. We hypothesized that the proposed method, would allow the design of more tailored and flexible lighting solutions. Allowing the adjustment of standards based on objective data for a specific user-space relationship. Promoting a more sustainable design practice that give an effective response to the user’s well-being and energy management, improving the nighttime experience. To test the hypothesis, an outdoor field experiment was conducted as a first case study, in the Village of Arraiolos, Portugal. A second experiment was carried out, aiming to test the consistency of the previous data and confirmation of the primary hypothesis. After analysis and statistical validation of the collected data, we can say that the tendency of choices in both experiments was very similar, meaning that the initial lighting scenarios considered as adequate were real and meaningful, with a high appraisal of lighting quality. It also showed that there was a relationship between the lighting configuration, visibility distance and the perceptual illusion of a fully lit space. Moreover, it shows that the majority of participants would accept adaptive public lighting, as common practice within the Perceived Luminance Continuity framework. Based on the results, we concluded that the proposed method is a valid tool for the design of adaptive public lighting solutions. Confirming the primary and secondary hypothesis, showing its relevance in the development of a more sustainable lighting design practice and improving the sustainability of the urban nighttime space.

Streszczenie:

This thesis is an exploration of how artificial lights are used to create atmospheres in a space, andhow they enhance an individual’s well-being. The focus here is placed on students in Sweden,specifically those who live in one-room apartments. Students typically do not invest much intheir lights yet being in Scandinavia, artificial lighting is used to compensate for the lack ofdaylight hours. As such, the lights they have will impact how they go about their day.A light is designed using product design methods to respond to the research question: “to whatextent can a versatile light source alter the atmosphere of a student’s space to enhance their wellbeing?”As the research is situated in Sweden, aspects of the Scandinavian lighting culture will beexamined and implemented in the design. The student’s well-being will be assessed through thetheory of subjective well-being, specifically how it can be enhanced through perceived control.The light design also aims to be socially sustainable, focusing on how individuals’ well-being canbe improved through lighting. The design also attempts to tackle inequalities by showing it canbe made of cheap and accessible materials, as well as being professionally manufactured. Thecheaper version is to ensure students with lower incomes can access the same quality of light asothers, where the light will create a similar atmosphere. Finally, the concept of social lighting isdefined in the context of this thesis. It concentrates on designing the light based on interviewswith students and emphasising the relationship between a student and their apartment.Through interviews and photos, a design brief was formed to understand what type of lightstudents use in their apartment and what they were looking for. After a series of iterations, afinal design was obtained and created. One version was made professionally in metal by BelidLighting. Another was made out of thick card and paper clips, materials easily accessible tostudents. The models were tested by students in their home for two nights, after which aninterview took place to obtain impressions and feedback on the design.It was concluded that a versatile light source altered the atmosphere of a student space toenhance their well-being to a certain extent. This was due to people’s existing relationship withlights, where they don’t generally interact beyond switching them on and off. Nonetheless,participants enjoyed making their own lamp, and found the lamp design quite unique. Thishelped maintain their subjective well-being.

Streszczenie:

Tylö AB is the leading manufactor of sauna cabins in Europe, but there is a lack

of a sauna lightning produced by Tylö. The project of developing a new sauna

lightning series was assigned two students at the developmentengineering

program at Halmstad University. The main problem with lightning in the sauna

is the heat and security aspect. The selection fell on LED technology as the

lightning source, thanks to its small measures and low heat emission.

The work of constructing of a lightning armature which the capability of cooling

down the LED lightning was carried out during autumn ‐06 and spring ‐07. The

project resulted in a brand new concept of sauna lightning, the usage of LED

technology in the sauna have opened up new possibilities for designed sauna

lightning. The lightning concept replaces an ordinary wooden panel in the

sealing, the only visible part is the glass cover. By using a smart deign combined

with extrusion of aluminum a profile only 12 millimeters thick that`s suitable

for mounting in the sauna sealing was constructed. The construction

guarantees an efficient cooling and sufficient lightning.

The project resulted in a patented and design patented product. The project

has further more resulted in a employment at Tylö AB for the project members.

The purpose with the employment is to take the product from a concept state

to a market introduction in end of 2007.

Streszczenie:

A significant problem in the automatic design of 3D graphics is the configuration of the lighting for a scene. The number of lights included, and the properties of these lights, has an enormous impact on what a viewer can judge about the content (the objects), properties (the geometric characteristics and spatial relations of the objects) and other aesthetic qualities of a scene. The traditional approach to lighting design for image synthesis is based on manual design methods, whereby users interactively specify values of lighting parameters, render the scene, and modify the lighting parameters until the desired visual properties of the scene are achieved. Non-expert users encounter a number of difficulties in selecting the appropriate lighting parameters, as the process requires both a subtle technical and aesthetic understanding of lighting in computer graphics. In this thesis, perceptual aspects such as contrast and the non-linear characteristics of our perceptual response to colour are combined with practical studio lighting techniques and a novel treatment of shadows, to yield an extension to existing perceptual approaches to lighting design. This so-called ideal lighting approach optimises the lighting configuration for a scene with respect to a set of absolute perceptual metrics. An intuitive approach to lighting design, lighting-by-example, is also proposed and extensively explored in forms that exploit both the perception-based lighting framework and a new wavelet formulation. User studies are conducted both to configure the perception-based lighting objective function and to evaluate the performance of the proposed lighting design approaches. Finally, we develop an interactive interface for the lighting design process that incorporates both the ideal lighting and lighting-by-example approaches.

Streszczenie:

My thesis will encompass the completion of the lighting design for W. S. Gilbert and Sir Arthur Sullivan's opera The Mikado and a post-production written documentation of the entire production process. The thesis will involve the completion of a lighting design with all of its accompanying paperwork generated in AutoCAD and Excel. The design will require lights for a two-act, multi-locational musical. Lights will need to provide a bright environment that can transform to the various locales. The entire design process will involve close communication with the entire design team, the director and the shop crew. As lighting designer, I will have to communicate with the Master Electrician and instruct him or her on the proper hang and circuiting of all instruments and provide detailed paperwork to ensure the light plot is hung correctly. With the Master Electricians help I will focus and gel all instruments. As lighting designer, I will also write cues and any special lighting effects for the show. During technical rehearsal week I will continue to maintain close communication with the director, making any necessary changes to create a better artistic product. The whole process will involve close collaboration with all of the design areas and an open communication so that lights enhance all elements of the show. As lighting designer, I will have to develop a vocabulary to communicate the abstract ideas of light and communicate them well enough so that the final product is both what the director and I imagined. During this process, I will maintain a journal that details the steps throughout the process and will act as a record of the discoveries and setbacks that occur. I will also provide research to support all of my creative decisions. I will also provide a strong informed basis for the design. The written portion of the Thesis will document the design process from early concept discussions through the completion and opening of the show. The thesis will examine the artistic developments and growth, as well as reflect on the overall success and development of the design. The personal journals maintained throughout the process will be edited and included for insight into daily growth of the design. The inclusion of these journals will also provide insight into the working relationship and nature of my collaboration with all the departments.
