the white lamp voltage is 3V. GU10

 Although the three colors red, green and blue LED lights blend out backlight wide color gamut,  LED Downlight but there are red edge phenomenon. In this paper, white LED as the main light source, and then use the orange light and blue light as a complementary color light source, get a screen white color temperature in (6 500 ± 100) K or less, the color coordinates u 'at 0. 198 ± 0. 01 or less, v 'at 0. 468 ± 0. 01 within the standard white light.

Two complementary color circuit diagram  LED Strip

White LED phosphor is excited by blue $ obtained white, because the LCD screen on the shortwave component is greater than the long-wave component of the decay, so white light LED light yellowish color after a screen, both need to make Blu-ray, but also to fill red.

20mA current flowing through the case of a typical room temperature orange lamp voltage is 2V, blue lamp voltage is 3V, the white lamp voltage is 3V. GU10

Three kinds of lights are 8 string. Orange light in the case of a typical current job requires only about 16V to its linear constant current source driver circuit efficiency less than 60%, due to the complementary color of orange light is therefore the maximum power consumption is less than 1W; white light and blue light linear Power efficiency over 85%.
