Wall lighting also use LED lighting panel appearance LED60cm square

Held in Tokyo in recent days show, several manufacturers exhibited a large area of light through the LED to achieve a "wall of light" or "ceiling light" case. The reverse shows a "LED is the light source can not be used as a surface light source" view.

Taiwan factory, a subsidiary of Ascension Coretronic Lighting has developed a 60cm square LED lighting panels, the exhibition will be posted on a display on the wall. Lighting panel thickness of only 12mm, the power consumption of 45W. Luminous efficiency of up to 67lm / W. In color temperature between the lower and SN74ABT16244ADLR datasheet and higher light switch, but also adjust the brightness. The development of lighting products rose almost no bright spots, and SN74ABT16244ADLR price and higher brightness. The company said that "by the parent company in the development of strong backlight optical light guide technology, eliminating the bright spot." The product has been listed in Japan and SN74ABT16244ADLR suppliers and other places. "Prices vary, so there is no announcement."

Not the same as with the rose light, "dims the brightness using the light guide plate," so the company does not use light guide. But in higher and lower color temperature for a group of two LED will be 200 groups of such a composition, a total of 400 LED arranged in the panel. Luminous efficiency, calculated from the brightness and power consumption to 60lm / W or more. Can use remote control dimming and color temperature. Currently, the products have been listed, "a 60cm square panels to 15 million yen, about other competing companies in Japan 1 / 2. LED Crees products used by the U.S. (which uses the Nichia Chemical industrial products lighting panel). " One of the reasons cheap is entrusted to South Korean companies manufacturing business.
