Showa Denko K.K. (SDK) has begun commercial shipment of aluminum-gallium-indium-phosphide (AlGaInP) ultrabright red LED chips with luminous efficiency of 80lm/W, touted to be the highest level on the market. The luminous efficiency of the new product represents a 40 percent improvement over SDK's existing grade.

The new product features high efficiency of bringing out light with the improved shape and arrangement of electrodes and chip surface treatment. This enables to maintain same level of brightness with less of LED lamps, thus contributing to energy conservation.

AlGaInP ultrabright LED chips are now used mainly in outdoor displays but new applications are being developed, including automotive parts (rear lights, interior lighting) and LCD backlighting for flat-panel TVs. SDK plans to further improve the brightness of AlGaInP ultrabright LED chips and provide them in diverse colors, such as red, orange, yellow, and yellowish green, and in a wide variety of sizes as required by respective customers.
