To evaluate the performance of white LEDs as museum lighting, the authors have conducted research and reported on the effect of illuminance level and color temperature on textiles dyed with natural dyes. In this research, four additional white LEDs with various correlated color temperatures and different material constructions and three types of conventional fluorescent lamp were tested yellow textiles that were sensitive to light and ranked in the highly responsive category of the CIE Technical Report (CIE-157-2004) for blue and red dyes. The color degradation degree caused by white LEDs was almost larger than that caused by conventional NU fluorescent lamp. Among the white LEDs, the degradation degree was LED/D (7483K) > LED/UV+RGB (5265K) > LED/B+YAG (5098K) > LED/L (3633K). For the same illuminance level when the content of the 400-500 nm radiation became larger, the degradation degree became larger. When the correlated color temperature was the same, the degradation degree was larger with LED/UV+RGB than with LED/B+YAG. The acceleration degree of degradation differed depending on the LED construction (combination of LED chip and fluorescent material) . From these results, it can be determined that for introducing white LEDs to museum lighting, not only the annual maximum exposure but also the material construction (combination of LED chip and phosphor) should be considered.

This study investigates how the season and the correlated color temperature affect the impression of lighting. However, subjective evaluation inevitably has individual variation. Therefore, the purpose of this paper is to clarify how within- and between-subject variation changes. The experiment variables are the season, the illuminance of the room, and the correlated color temperature of the fluorescent lamp. The seasons are summer and winter, there are 12 levels of vertical illuminance of the room from 0.5 to 2000 lx, and the correlated color temperature of the lamps are 3000 and 6700 K. The subjects are 27 to 31 young women. They evaluate brightness, glare, comfort, and relaxation effect of the lighting. In conclusion : 1) Brightness, glare, and comfortable sensations change depending on the illuminance. The influence on the relaxation effect due to the illuminance is small, and the relation is clear for each individual. The subjects have suitable illuminance levels for relaxation. 2) All four items are influenced by the change of illuminance level in between-subject variation. The range of illuminance in which the evaluation between subjects stabilized is as follows: brightness is 500 lx or more, glare is 50 lx or less, comfort is from 20 to 50 lx, and relaxation is from 10 to 20 lx. 3) The variation between individuals is larger than the variation for each individual, though there is little difference with changes in illuminance.

Improving the lighting environment in offices leads higher levels of intellectual productivity. We constructed a system that provides the individual illuminance and color temperature preferred by workers, and we carried an experiment to clarify which illuminance and color temperature in the office were preferred. The result of this experiment show that each person's favorite lighting environment was different and it changed with their state of health and time of day. We consider that creative works improved when workers were provided with a lighting environment they preferred.

Incandescent lamps were invented approximately 130 years ago, and the most intelligent brains of the Europe, US, and Japan worked on incandescent lamp improvements and new product developments. As a result, incandescent lamps came to dominate mainstream illumination systems. Although new light sources such as fluorescent lamps have emerged since then, incandescent lamps have been used everywhere in the world to this day for the unique warm color of their light, and for the cozy feeling they create that people associate with candles and kerosene lamps. However, the 130 year history of incandescent lamps is now coming to an close, due to the significant mission of global warming prevention. From a historical perspective, we are now entering an era of innovation that arrives approximately once every 60 years. It is the dawn of an era of LED illumination that takes advantage of solid-state lighting, which is different from combustion- or electrical-discharge-based lighting. Brilliant researchers and engineers are now starting to work on improvements and refinements of LED lights, the same way their predecessors did 130 years ago. The world will soon be illuminated by the glow of LEDs. This article gives an overview of the history of the incandescent lamp in Japan, and introduces the history of various technologies that supported the development of incandescent lamps.
