Advantages of LED bulbs: You can control the size of the forbidden band width of the semiconductor light-emitting layer of semiconductor material to emit various colors of light, and higher saturation. LED light having strong directivity, which can better control the light, improving the lighting efficiency of the system. The use of low-voltage direct current, with a load of small, weak interference advantages. LED bulb white LED bulb especially in the field of general lighting and energy saving potential advantages. LED and its basic structure is an electroluminescent semiconductor materials chip Buy 2w bulb, with silver or white glue curing glue onto the bracket and the wholesale price of silver or gold thread connecting the chip and board 2w bulb, then sealed with epoxy resin around, play a role in protecting the internal core wire 2w bulb, the final installation shell, so the seismic performance of LED lights. LED lights principle: LED light-emitting diode, is a way to convert electrical energy into visible light solid-state semiconductor devices, which can be converted directly into electricity to light. Buying 2w bulb, Hang Li saving (certified), Shanxi 2w bulb provided by Anyang Hi-tech Zone Heng Lai energy-saving lamps 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. Hang Li leadership in energy efficiency with the staff warmly welcome all inquiries negotiations to create a constant Korea saving a better future.
