Tsinghua University and Industrial Research Institute (ITRI) in Taiwan recently released the research results of "ultra-low color temperature OLED light source", which appeals to surface light source, light dispersion and high color uniformity. The team believes that OLED ultra-low color temperature light source can reduce the risk of cancer, and ITRI will mass-produce this technology in the future, without excluding technology transfer.
The color temperature of this light source is 1800K to 2000K, and the light color is very yellowish red. International manufacturers include OLED lighting panels from Panasonic, Osram, etc., and the demand is still white light with higher color temperature. This ultra-low color temperature product has almost no products.
The project expert said that it is traditionally considered that the low color temperature is reddish and gives a warm feeling, while in the daytime it is suitable to use high color temperature and white light with blue color. However, according to research by foreign scholars, a light source with a high color temperature will affect the secretion of melatonin, and there is some correlation with the disease. The expert believes that light sources with low color temperatures should be used as much as possible to reduce the risk of cancer. The study also applied to the Ministry of Economic Affairs of Taiwan for a plan of NT$18 million, which is expected to be listed within two years. In addition, the ITRI also said that it hopes to suggest that the government can legislate to force the market fixtures to indicate the color temperature.
However, the research on whether the light source is related to disease, the opinions of the industry and the academic community are still inconsistent, and some people have reservations because melatonin is a hormone, although previous studies have suggested that the secretion of this hormone is exposed to sunlight. influences. According to the theory, any photothermal source is a type of radiation, and its degree of danger is inversely proportional to the distance. The sun, fluorescent lamps, traditional light bulbs, and LED bulbs are all light sources. If theoretically, LED lighting fixtures have lower energy than general fluorescent lamps and halogen lamps, and there is no clinical data showing that the light source of the lamp causes signs of melatonin reduction or even cancer.
