Mitsui metal for the development of UV LED accident mixed with a good white phosphor

Mitsui metal with near ultraviolet LED used in combination to realize white light as the premise, has developed a good mix of white phosphor, and in the "FPD International 2006" on the first show. After the user needs to mix red, blue, green colored phosphors, due to the uneven quality of various materials, it is difficult to achieve the required white. Due to the completion of the mixing of the phosphor, it can simplify the production process of the user, in addition to the day white (white) to the bulb color (yellow light) 2800K ~ 10 thousand K color temperature range to get the ideal white. A variety of powder is not dividends, blue, green, are white, improve the uniformity of white. Prior to the industry generally believe that, from raw materials to sintering, and then to the crushing, it is difficult to use a process to complete the production of white phosphor, but Mitsui metal through the optimization of materials and processes to achieve this goal. Compared with the original production process of red, blue and green phosphors, the working hours are only 1/3, and the cost can be reduced. The company on the FPD International 2006 for the first time introduced this white phosphor, the future also intends to implement the sample supply and user evaluation. (reporter: Kimura Masahide)
