The key LED design LED chip technology development is the base material and epitaxial growth techniques. Sapphire substrate material from the traditional materials, silicon and silicon carbide, the development of zinc oxide, gallium nitride, and other new materials. In just a few years, by means of a series of technical improvements including chip structure, surface roughening treatment and multiple quantum well structure including design, professional production Shaanxi Showcase Light, LED light effect in achieving a tremendous breakthrough. The benefits of LED lights in high-brightness white LED, the Shaanxi showcase light bar manufacturers, a small portion of the blue after Stokes shift has a longer wavelength. This is a good thing, because it makes LED lamp manufacturers can use many different color phosphor layer, showcase lights, to extend the emission spectrum, effectively improve the LED color rendering index (CRI). High CRI white LED using the phosphor obtained at a price, because the Stokes shift will result in lower than the efficiency of white LED color LED efficiency. But for most lighting applications, preferring to use high CRI and a slightly lower efficiency LED lights. Shaanxi Showcase Light Company _ Chun away Lighting (Online) _ showcase light bar away from the Shenzhen Lighting Limited. Lighting Co., Ltd.
