Stanley produced a large area of the backlight light guide plate LED lighting equipment

The Japanese Stanley developed length 1.2m, the power consumption of LED lighting 40W, and lighting technology and lighting equipment exhibition "Lighting Fair 2009" (the Tokyo International Exhibition Center, March 2009 3 ~ 6 days) on display.

The LED lighting is the 20W will be installed in the company's LED sales of the existing backlight light guide plate products at both ends. The length of the light guide plate is 1.2m, "is by far the longest light guide plate" (Stanley).

"Just below the lighting brightness at 2m 380lx (Lux)" (the company). The luminous efficiency of LED is 70lm/W. Because the luminous efficiency of the illuminating apparatus is very high, and there is no instrument to measure, the utility model has not been measured.

The use of the existing light guide plate products, there are still some problems. "The light emitted by the left and right sides of the LED is converging in the middle, producing an uneven brightness" (Stanley). To solve this problem, it is necessary to adjust the configuration and density of light diffuse reflection in the light guide plate. "Plans to use special lighting light guide new development pattern optimization in the next products" (the company).
