Abstract:

This streetlight monitoring system is aimed at preventing unnecessary energy wastage by applying the GSM (Global System for Mobile Communications) technology. This system consists of two parts: the monitoring centre and the terminal nodes. The Siemens TC35 GSM module is used to send and receive short messages and it is installed in the monitoring centre and each streetlight. ATmega168 is used to determine whether or not it is necessary for the streetlights to be turned on, and then it executes commands from the control centre. When the sky is bright enough for drivers, the streetlights will automatically turn off. Also, if some streetlights are broken down, the TC35 GSM module will send an alarm short message to the monitoring centre and maintenance personnel will repair the lights as soon as possible. Thus, maintenance personnel will no longer have to make time-consuming visits to check up on the function status of every streetlight. All information is presented in the monitoring computer which is programmed in LabVIEW. The workman can easily turn on or off any streetlight by clicking on the screen.

Abstract:

A wireless monitoring system was carried out to manage the streetlight in Tianjin bonded area. The system adapted a concentric dropping voltage energy-saving mode and the single lamp was monitored without control. The single lamp’s electrical information was trapped by a detecting module and sent to the communication terminal by power carrier technology. Then the collected information of termination was transferred to a remote monitoring center by GPRS communication module. The streetlights in the subsection were on-off by combining timing with illuminance. The practice shows this system is reliable and effective.

Abstract:

Replacing failed bulbs of streetlights in a location can be very tasking and expensive if the optimal time for replacement is not determined. In this paper, a model has been developed that helps to establish the optimal time for the replacement of streetlight bulbs. Burnt-out bulbs are replaced individually when they fail, and group replacement is carried out on all bulbs after a specified time. The costs for both individual replacement and group replacement are determined. The developed model was applied to locally sourced data from a field survey of a streetlight installation at the University of Ilorin, Ilorin, North-central Nigeria. The model gave the optimum replacement time of burnt-out bulbs as the eighteenth week when applied to the data used in this work. The optimum replacement time will be dependent on the dataset used. This makes the developed model useful in establishing the optimal replacement time of any stochastically failing items that are in large quantities. The model will help to reduce maintenance costs for facility managers.

Abstract:

Solar-led streetlight is a hotspot in photovoltaic lighting at present, it combines solar energy with HB LEDs (High Brightness Light Emitting Diodes) called the fourth generation of light source to improve the conventional streetlight in several aspects. Due to the clean nature of solar energy, and the highly efficient energy conversion of the PV module and very long operating life of the HB LED, the solar-LED streetlight, compared to traditional streetlight, can save electricity remarkably, thus abating greenhouse gas emission. During the photovoltaic lighting system, MPPT technology is generally used with the aim of maximizing the solar panel output power from beginning to the end. Therefore, if the controller combines MPPT technology with the traditionally constant-voltage charging technology, the charge efficiency will be greatly increased. While, for the discharge issue, people hope to modulate the brightness of streetlight so as to decrease the electricity consume.

Abstract:

This paper presents a single-stage driver with soft-switching and interleaved power-factor correction (PFC) features suitable for light-emitting diode (LED) energy-saving streetlight applications. The proposed LED streetlight driver integrates an interleaved buck-boost PFC converter with coupled inductors and a half-bridge LLC resonant converter into a single-stage power-conversion circuit with reduced voltage stress on the DC-linked capacitor and power switches, and it is suitable for operating at high utility-line voltages. Furthermore, coupled inductors in the interleaved buck-boost PFC converter are operated in discontinuous-conduction mode (DCM) for accomplishing PFC, and the half-bridge LLC resonant converter features zero-voltage switching (ZVS) to reduce switching losses of power switches, and zero-current switching (ZCS) to decrease conduction losses of power diodes. Operational modes and design considerations for the proposed LED streetlight driver are introduced. Finally, a 144 W (36V/4A)-rated LED prototype driver is successfully developed and implemented for supplying a streetlight module and operating with a utility-line input voltage of 220 V. High power factor, low output-voltage ripple factor, low output-current ripple factor, and high efficiency are achieved in the proposed LED streetlight driver.

Abstract:

This work presents the development and construction of an adaptive street lighting system that improves safety at intersections, which is the result of applying low-power Internet of Things (IoT) techniques to intelligent transportation systems. A set of wireless sensor nodes using the Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 standard with additional internet protocol (IP) connectivity measures both ambient conditions and vehicle transit. These measurements are sent to a coordinator node that collects and passes them to a local controller, which then makes decisions leading to the streetlight being turned on and its illumination level controlled. Streetlights are autonomous, powered by photovoltaic energy, and wirelessly connected, achieving a high degree of energy efficiency. Relevant data are also sent to the highway conservation center, allowing it to maintain up-to-date information for the system, enabling preventive maintenance.

Abstract:

Many smart city applications have been proposed and demonstrated over the years; however, moving to large-scale deployment is still scarce. A contributing factor to this scarcity is the lack of well-established engineering methodologies for large-scale smart city applications. This paper addresses engineering methodologies and tools for large-scale smart city application engineering, implementation, deployment, and evolution. A model-based engineering approach based on IoT, SOA, and SysML is proposed and applied to a smart streetlight application. Engineering considerations for streetlight area enlargement and updated technology generations with additional capabilities are discussed. The proposed model-based engineering approach provides considerable scaling simplifications and opportunities for considerable savings on engineering costs. The model-based engineering approach also provides good documentation that enables technology evolution specifications that support both maintenance and emerging behaviours.

Abstract:

Under stable atmospheric conditions the brightness of the urban sky varies throughout the night following the time course of the anthropogenic emissions of light. Different types of artificial light sources (e.g. streetlights, residential, and vehicle lights) have specific time signatures, and this feature makes it possible to estimate the amount of brightness contributed by each of them. Our approach is based on transforming the time representation of the zenithal night sky brightness into a modal expansion in terms of the time signatures of the different sources of light. The modal coefficients, and hence the absolute and relative contributions of each type of source, can be estimated by means of a linear least squares fit. A practical method for determining the time signatures of different contributing sources is also described, based on wide-field time-lapse photometry of the urban nightscape. Our preliminary results suggest that, besides the dominant streetlight contribution, artificial light leaking out of the windows of residential buildings may account for a significant share of the time-varying part of the zenithal night sky brightness at the measurement locations, whilst the contribution of the vehicle lights seems to be significantly smaller.

Abstract:

Regulatory policy for genomic testing may be subject to biases that favor reliance on existing regulatory frameworks even when those frameworks carry unintended legal consequences or may be poorly tailored to the challenges genomic testing presents. This article explores three examples drawn from genetic privacy regulation, oversight of clinical uses of genomic information, and regulation of genomic software. Overreliance on expedient regulatory approaches has a potential to undercut complete and durable solutions.

Abstract:

Background/Objectives: Typically, the stand-alone solar streetlight system is used independently of DC/DC converter for battery charging and for LED lighting control. Such an independent power conversion system uses a DC/DC converter with only a voltage raising or reducing function for cost reduction (power semiconductor, inductor, capacitor, etc.). However, these DC/DC converters have limitations on efficiency increase in all voltage ranges when controlling MPPT. In addition, DC/DC converters for LED lighting have limitations in the design of the lighting voltage because the LED lighting operates only at voltages lower or higher than the battery voltage. Therefore, In this paper, a new power conversion system using a DC/DC converter for battery charging and for streetlight using a bi-directional buck and boost DC/DC converter.Methods/Statistical analysis: A prototype was fabricated and tested. The used equipment was a Tektronix oscilloscope, 24V (Lead-Acid) Battery, PV Simulator (ETS 1000X10D PVF_Sorensen) and WT 3000 (YOKOGAWA).Findings: By using a shared converter, cost savings were achieved by reducing the number of power semiconductor devices and the number of inductors and capacitors. In addition, it works as an input / output step-down converter to compensate the voltage design limit.Improvements/Applications: In <30 words.

Abstract:

Artificial light at night is considered a major threat to biodiversity, especially for nocturnal species, as it reduces habitat availability, quality, and functionality. Since the recent evolution in light technologies in improving luminous efficacy, developed countries are experiencing a renewal of their lighting equipment that reaches its end-of-life, from conventional lighting technologies to light emitting diodes (LEDs). Despite potential cascading impacts of such a shift on nocturnal fauna, few studies have so far dealt with the impact of the renewal of street lighting by new technologies. Specifically, only one study, by Rowse et al.2016, examined the effects of switching from widely used low pressure sodium (LPS) lamps to LEDs, using bats as biological models. This study was based on a before-after-control-impact paired design (BACIP) at 12 pairs in the UK, each including one control and one experimental streetlight. If Rowse et al. 2016 showed no effect of switching to LEDs streetlights on bat activity, the effects of respective changes in light intensity and spectrum were not disentangled when testing switch effects. Here, we conduct a retrospective analysis of their data to include these covariates in statistical models with the aim of disentangling the relative effects of these light characteristics. Our re-analysis clearly indicates that the switches in spectrum and in intensity with replacement of LPS with LED lamps have significant additive and interactive effects, on bat activity. We also show that bat activity and buzz ratio decrease with increasing LED intensity while an opposite effect is observed with LPS lamps. Hence, the loss or the gain in bat activity when lamp types, i.e., spectrum, are switched strongly depends on the initial and new lamp intensities. Our results stress the need to consider simultaneously the effects of changes in the different lights characteristics when street lighting changes. Because switches from LPS to LED lamps can lead to an increase in light intensity, such technological changes may involve a reduction of bat activity in numerous cases, especially at high LED intensities. Since we are currently at an important crossroad in lighting management, we recommend to limit LED intensity and improve its spectral composition toward warmer colors to limit potential deleterious impacts on bat activity.

Abstract:

A finite elementmodel of a 9-meter-high wind-solar hybrid powered street light was established;statics analysis, modal analysis and harmonic response analysis were performedusing ANSYS. Static analysis determined the maximum deformation and stress of astreet light under complex load, and checked its intensity and rigidity. Modalanalysis and harmonic response analysis obtained a vibration mode of a streetlight and its natural frequency of every order. The results of analysesprovided references for the optimization of street light structure.

Abstract:

To solve the problem of repeated loss of low voltage power cables, this paper designed a project in preventing the cables from stealing. The design of the system is based on the Impedance Characteristics method which is used in power-on state and the Parallel Resonance which is used in power-off state. The paper describes the principle of the method and how to combine the two methods. The simulation and test for it show that the method is correct. The system makes it possible to protect the cable from stealing without affecting the electricity system. In addition, it can calculate the fault location. The system has better accurateness and stableness than the common cable anti-theft system.
