Cree launched backlight with blue LED, optical power multiplication of 370mW

The day before Cree launched into the high power blue 350mA current time power of 370mW light emitting diode (LED) chip EZBright1000". Optical power is more than 2 times the company's original products. If the incoming current is increased to 1A, the optical power can be increased to 800mW. The utility model is suitable for the general lighting equipment, the vehicle equipment, the back light of the liquid crystal panel, and the equipment which uses the LED as a light source projector, etc..

When making the white LED, we need to combine the blue LED chip and the phosphor material. In June 2006 2006 held by LED (LED Technology Symposium Technology Conference 2006), "Cree said if the light power of the blue chip LED to 360mW, you can get 100lm/W luminous efficiency of white LED. It can be speculated that the use of the chip can be made of 100lm/W high power white LED.

The forward voltage of EZBright1000 is 350mA when the current is 3.3V. Including the optical power of the smallest 200mW and 300mW, respectively, two models, the models were also equipped with a luminous wavelength of 450nm + 5nm, 460nm + 5nm, 470nm + 5nm range of products. Chip mounting size of 980 m x m 980. Chip thickness of 100 m. A negative electrode is arranged on the upper surface of the chip, and a positive electrode is arranged on the lower surface.
