 According to the relationship between the dimming, color temperature can be obtained at 6 500  MR16  ± 100K or less, the color coordinates u 'at 0. 198 ± 0. 01 or less, v' at 0. 468 ± 0. 01 within the standard white light. Changes in temperature, according to the data TCS230 color sensor trim orange lights and blue lights of the PWM high time to maintain the red, green and blue three color channels output a constant ratio between the number of pulses the color unchanged.

With led technology matures, the various colors of the LED have developed, while costs are substantially reduced. Output current above 300mA LED driver circuit common with inductive switching and linear power drive mode is also useful for switching and linear power union-driven approach. Linear power driver circuit is almost no ground bounce and ripple of the circuit resulting interference, commonly used in the electromagnetic compatibility requirements of the occasion.  LED Flexi

Multi-color LED color mixing complementary color backlight technology is the current research focus. Back in 2000, the Japanese had to produce multi-chip-type LED backlight products. Subsequently, the major companies have launched a multi-chip-type LED-backlit high-performance LCD. But how specific complementary color mixing, and now the open literature, little.
