Chip is the core of LED bulb, it will directly affect the internal quantum efficiency of the LED bulb luminous efficacy bulb 3w wholesale, non-radiative recombination rate determines the size of the chip heat. You can say that only manufacture LED bulb chips with good quality, it may have superior performance of LED light bulb. In order to maximize the internal quantum efficiency and reduced non-radiative recombination rate bulb 3w, mainly from two aspects to improve the quality of the chip, which is a reasonable choice of chip defect density structure and control of the chip. LED's heart is at one end of a semiconductor wafer, the wafer is attached to a bracket on the bulb 3w price, one end is negative 3w bulb plant, and the other end connected to the positive power supply, so the whole chip is epoxy encapsulated. Semiconductor chip consists of two parts, part of the P-type semiconductor, the hole in it dominates the other side is an N-type semiconductor, here is mainly electronic. But when the two semiconductor connected together to form a PN junction between them. When the current through the wire act on the chip, electronics will be pushed to P zone electron hole recombination, and then will be issued in the P zone of energy in the form of photons, which is the principle of LED lights glow. Bulb 3w manufacturers _ Hang Li saving (certified) _ Shanxi bulb 3w provided by Anyang Hi-tech Zone Heng Lai energy-saving lamp factory. High-tech Zone Anyang Heng Lai energy-saving lamps factory (www.ayhljnd.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
