produce lighting all suit the use of LED lighting products

Mitsubishi has developed two different technologies to combat against the problems that occur when sapphire wafers are combined with yellow phosphor to create white light. The first is to increase the white LED color rendering to above 80. The other is to use UV LEDs with a wavelength of 400nm and add red, green, and blue phosphor to produce white light. Mitsubishi states that this will increase color rendering to above 90 and color reproducibility will be high.

Mitsubishi points out that UV wafers paired with red, green, and blue phosphor technology will have the same light composition as sunlight, with a color rendering index of about 95. When illuminated, light quality goals will be met without the appearance of a multiple array of colors. The application of this technology in areas such as residential indoor lighting, museums, commercial areas, and produce lighting all suit the use of LED lighting products which employ UV light paired with red, green, and blue phosphor to produce white light.

The ongoing patent lawsuit between Taiwanese LED packaging manufacturer Everlight and Japanese LED manufacturer Nichia heats up. The two companies have filed lawsuits in Japan, Taiwan, Germany, the U.S. and China. General Manager of Legal Affairs and Intellectual Properties at Nichia, Katsuyuki Akutagawa attended a press conference in Taiwan on September 13th. He stated that Nichia will no longer be passive during this dispute but fight back against Everlight’s patent infringement.
