LED has huge potential, it is lighting in the history of another leap after the incandescent lamp, fluorescent lamp, LED lighting revolution for the third time, the enormous economic benefit and social significance.
led downlight is the most important core component of LED, the LED is the nature of the p-n junction, the terminal voltage has a certain potential barrier, the leds put forward voltage and potential barrier, the fertility mutual diffusion of P and N area, the hole is much smaller k3sja8c than the electron mobility, so a large number of electrons to the p-region diffusion, the ShaoZi injection of P. Price is take the hole with electronic compound, the energy released in the form of light energy. This is the LED light-emitting principle.
First of all, to greatly improve the overall efficiency of led panel light package, reduce energy demand. Second, must provide higher performance advantages than incandescent bulbs. Such as in industrial applications, including from high-power internal and external lighting to drive the laser diode in cutting and forming raw materials of various applications. All of these applications need to significantly reduce the required power, but also need to be very specific performance improvements.
