Correlated color temperature is the temperature of a Planckian radiator which perceived color closely resembles that of a test stimulus. The International Commission on Illumination (CIE) has defined this measurement as being valid under specified viewing conditions and with the test stimulus being of the same brightness as the point of the Planckian radiator. The current method for calculation of the correlated color temperature dates back to 1968 and is based on an obsolete color space which is nowadays not used for any other calculations. The color space is valid for any viewing condition and the brightness is unknown. Color appearance models use viewing conditions and input stimuli to model perceived appearance. Correlates which include brightness and hue are mathematically defined. These parameters are exactly the requirement of the CIE definition for correlated color temperature but are currently not used in the calculation. In this research the definition of color temperature from the Planckian blackbody equation is used to find their locations in color appearance models. Given the blackbody locus as test stimulus different input situations are tested and the models'' outputs are compared. Finally a method for calculating the correlated color temperature in any color appearance model is given which conforms much closer to the CIE definition.

Light damage of museum object causes material irreversible aging and degradation. It is important to use the proper source of museum lighting. Therefore, evaluating the property of lamps is an indispensable part of conservation work. The main aim of the study presented in the paper was to evaluate museum lighting sources causing color degradation on different materials. Blue wool scale and actual material, including painting and calligraphy paper, mounting materials and Chinese pigments were exposed to four types of white LED lamps with different correlated color temperature and NU-fluorescent lamp. The measurement results provide further information about the benefits of LED lamps for museum lighting. The result of light sources measurement shows that low correlated color temperature (CCT) type LED characterized lower blue wave band ratio and damage factor. Under 300000 lx∙hr of accumulating exposed time, test result revealed LED lamp with low CCT caused a larger Color change of blue wool scale. For painting and calligraphy paper, mounting materials and Chinese pigments, the test result revealed that Color change by NU-fluorescent lamp was greater than LEDs. The comparison of different Color change by LEDs, machine-made paper fading faster under LED with lower CCT. Conversely, hand-made paper, mounting materials, and Chinese pigments fading faster under LED with higher CCT, and the Color change grows as CCT increase. The results of paper P.C. No. (post color number) values change and pH values are similar to the consequence of color change, namely the lamp which caused Color change lager also caused paper P.C. No. values decrease and pH value decrease. Additionally, some sample reacts with certain wavelengths result in larger fading. It is possible that action spectrum of material receiving. The relative evaluations of the discoloration degrees of actual materials after exposed of different light sources revealed LED lamps lower than NU-fluorescent lamp and the degrees decrease as CCT decrease. Furthermore, the LED lamps with lower CCT caused less degaradation. The research verified the blue wave band ratio, damage factor and CCT of light sources as evaluate suitability of light. The LED lamps result lower degradation of materials than NU-fluorescent lamp. It is appropriate to use LED lamp with low CCT as museum lighting.

In this thesis, we study color uniformity of white light LEDs with different package types. Based on the YAG phosphor model, we analyze the angular correlated color temperature deviation (ACCTD) for white light LEDs with different package types and find out which one is lowest. After that, we modify the ACCTD of specific package types with the same correlated color temperature by changing the structure of the package. Finally, we study the ACCTD changes in mid-field region for white light LEDs and define the distance of quasi far-field in color.

Light is a common cause of damage to collections. Paper, textile, binding media , dyes and pigments are particularly sensitive to light. Most of us recognize fading as a form of light damage, but this is only a superficial indication of deterioration that will extends to the physical and chemical structure of collections eventually. Most important, light provides energy to fuel the chemical reactions that produce deterioration. Light damage is cumulative and irreversible. Incandescent lamps have been phased out since 2010 in Taiwan and LED was the latest cutting edge lighting technology, considered as an alternative to traditional light sources. LED waves have swept the museum circle. There are some advantages of LED lighting, such as energy efficiency, ecologically friendly, response fast, small size, low quantity of heat and longer service lifetime. The limit of current technology restricts LED from so-claimed full performance concerning global illumination, color rendering and reliability. Therefore it is necessary to evaluate the use of LED lighting in museums. Blue wool standards were exposed to four types of white LED lamps under different color temperatures. Color changes were measured at each 15,000lx-hr interval twenty times. The accumulated exposed time were 300,000lx-hr. Test results showed that all LED lighting cause fading on blue wool standard grade 1 and the lower color temperature of light the fading rate was faster . The test result is different from former literatures may attributed to commercial LED lamps. The commercial lamps were made by different production and packaging processes based on cost and market trend considerations, such instability will be a potential damage to cultural relics. Color temperature as an indicator of light sources needs more evaluation analysis to testify its performance. It is important to develop a suitable illuminating system light sources in order to put white LED lamps into practical use as a museum light sources.

Recently, white solid-state LECs have attracted intense attention since they exhibit advantages such as low-voltage operation, compatibility with solution processes and employing inert cathode metals. Since different correlated color temperatures (CCTs) of background illumination are necessary for various lighting applications, a real-time tunable CCT of white LECs would be highly desired in modern smart lighting systems. In this work, a widely and dynamically tuning CCT (>10000 K) of white LEC is demonstrated by employing an electrochromic device (ECD) as a real-time controllable color filter. By increasing the applied bias on the ECD to attenuate more the red parts of white EL from the white LEC, the LEC-based white light source becomes more bluish and, in consequence, shows higher CCT. This proposed LEC-based white light source with the characteristics of wide CCT range and real-time tunability is suitable for most lighting applications and modern smart lighting systems.
