TOYOTA synthetic reference exhibits 3 white LED

TOYOTA synthesis in the March 7, 2006 opening of the "JAPANA SHOP 2006" exhibition, on display drive current respectively white light emitting diodes 20mA, 150mA and 350mA (LED). Including high brightness products, including a total of 3 kinds of 350mA products. 150mA mainly for vehicle navigation LCD panel backlight, 350mA products are mainly used for indoor lighting. The luminous efficiency of 20mA products, 150mA products and 350mA high brightness products were 65lm/W, 47.9lm/W and 37.8lm/W, respectively. Luminous flux were 4lm, 23lm and 45lm. The company has now developed the use of 500mA drive current white LED.

At the same time also announced a blueprint designed to improve the luminous efficiency of white LED. It is reported that the luminous efficiency is steadily increasing according to the blueprint.
