Average luminous intensity as a single tube. 11. General LED luminous life is very long, manufacturers are generally marked to 100,000 hours or more, should pay attention to the actual LED brightness decay cycle, as most of the UR for automotive taillights lit red tube more than a dozen to a few hours after , the brightness is only half of the original. Brightness decay cycle and LED production process has a lot of material, generally in the case of economic conditions permit should choose brightness decay slower four elements LED. Color, white balance: full-color hot in Tel 13662895447 business QQ1360988768 12. White is red, green and blue mixed in the ratio of brightness is made, when the green light brightness of 69%, 21% brightness of red, blue brightness of 10%, the blending eye descendants feel is pure white. But chromaticity coordinates of red, green and blue LED due process and other reasons can not achieve all chromatographic results, which control colors, including a deviation of brightness of colors are white light, called color. 13. When the color matching before the full-color LED display, in order to achieve optimal brightness and lowest cost, should try to choose RGB luminous intensity of roughly 3: 6: 1 ratio of LED devices composed of pixels. 14. White balance requires three primary colors in the same tone gray value remains as pure synthetic white. 15. The primary, primary colors: 16. colors that can synthesize a variety of colors of the basic color. Shade in the colors red, green, blue, next picture shows the spectrum table, in which the three vertices of an ideal primary color wavelength. If there are deviations colors, the color can be synthesized region will be reduced, the spectrum triangular table will be reduced, from the visual point of view, the color deviation will not only reduce the richness.

LED emitted green and blue light at different wavelengths according to their characteristics and is broadly divided into purple, pure red, orange, orange, orange, yellow, green, pure green, green , cyan, blue, violet, etc., orange, green, blue and purple than pure red, pure green, Chunlan much cheaper prices. The three primary colors of green is most important, because the green occupy 69% brightness white and color at the center of a lateral row of the list. Therefore, purity and price trade-offs between colors welcome new and old customers to consult, State-kai photoelectric LED display 13433407439 Mr. Zhu was responsible for the majority of projects to provide 24-hour telephone service, please call product design, engineering solutions, a wide range of information technology index, structural design and installation guidance.
