Lamp phosphors Qinghai lamp phosphors manufacturers _ _ Zi Qi

 Currently, rare earth cerium-activated yttrium aluminum garnet structure with a blue LED with yellow phosphor to produce white light emitting efficiency way the best, but because of the phosphor glow in the red part of the serious shortage of energy-saving lamp phosphors, resulting in white LED products color is poor, unable to take advantage of the single phosphor preparing a low color temperature, high color rendering white LED. This "blue chip gluten products as a light source lamp phosphors, in the visual sense too cold; as the LCD backlight, display color gamut narrow lamp phosphors Which is good, full-color ineffective uses." Blu-ray Pink Rot display chip index produced white LED devices despite a substantial increase (80 or more), but to show a higher index (90 or more), you must join the green phosphor. Phosphor by absorbing a specific wavelength of the UV light source, by the energy of the light source produces a color change (to purple, red, blue, yellow, green, etc.), sunlight or ultraviolet light, i.e., will be from colorless to colored, discoloration principle: the use of energy UVA photosensitive molecules key to open, making it jump from low energy bands energy bands. That is never visible skip visible, resulting in a change in color. When the loss of ultraviolet radiation or temperature rises above 45 ℃, the light-sensitive molecules bond closed, ie back to the original color. Dreaming powder is treated via microencapsulation technology products, the appearance of powder, particle size between 1 ~ 10μm, and having a high temperature, oxidation, etc. microcapsules modified characteristics. Phosphor Properties and Applications: phosphor appearance of a white powder, the UV light excitation may be issued domestically colorful red lamp phosphors, it stable chemical properties, non-toxic, insoluble in water, is a high efficiency light emitting material. It can be used as an additive widely used in a variety of architectural, interior lighting, holiday lights, underground passage, outdoor advertising signs, neon signs, lights, and other places, and other applications that can be developed. Dreaming of factors influence the effect of: 1, UVA ultraviolet light: not long-term exposure to UV light. 2. Heat: above 45 ℃ prone to shock and lose the ability to change color.
