Japan Color Research Institute: color difference will affect LED lighting applications

Japan Color Research Institute in the day before the latest white LED lighting technology and trends seminar "pointed out that light, color plays an important role for LED lighting, if the quantization digital LED color index and eye viewing results can not reach agreement, the future will influence into the LED lighting application opportunity.

The agency is a professional organization focused on color research, they found that in the condition of constant reflectance, eye for red, green and blue colors will have 3 different wavelength sensing reaction, and because of the different environment and changes are different.

At this stage, Ra is the most commonly used color rendering index, the higher the Ra value, the higher the color rendering. And if the Ra value is less than 60, its color is not up to standard. RGB white light LED to test, the human eye will not be able to distinguish the difference between the phenomenon, the reason is that the difference in color rendering Ra.

Europe and the United States have been using the Ra value for a long time, while the Japanese side is expected to have a new index to test LED products, will be 2 years, the new light source for the test method of color rendering a new program. Future Taiwan industry will also be faced with the difficulty of presenting information to the corresponding color, color will become a necessary problem to solve the LED lighting.
