Toshiba set to ramp up white LED production
Toshiba Corporation will soon be offering customers white LEDs suitable for general lighting and LCD backlighting.
The company's flagship LED, the TL10W02-D, which generates 60 lumens at 2W and 500 mA, will begin sampling in July. Production of 1 million units per month is expected by October.
According to the company, the LED's high performance characteristics result from improved chip-mounting technology and better thermal management, thanks to a low thermal resistance package.
Toshiba says that the excellent heat dissipation characteristics also maintain the chip's luminous linearity at a drive current of up to 700 mA.
The company will also begin sampling the 30-lumen TL10W01-D in June, with manufacture of 1 million units per month to follow in July.
Although Toshiba is not a company strongly associated with GaN LEDs, back in 2001 it teamed up with Toyoda Gosei to produce white emitters (see related story).
The LEDs, which combined Toyoda's chips with Toshiba's phosphors, were marketed by both companies under their own brand names.
• Nichia intends to mass-produce large white LEDs for the backlighting of 10 inch computer screens and 5-8 inch car navigation displays, according to the Japanese newspaper Nihon Keizai Shimbun.The report says that Nichia's 200 cd/m2 LEDs will offer PC screen manufacturers a 150% improvement in illumination.
