With the rapid development of LED technology, the luminous efficiency enjoy continuous improvement, LED lighting technology is also developing rapidly. LED spotlight is now almost an alternative to traditional halogen based. Compared with traditional lamps, LED lighting has a significant advantage in terms of energy efficiency and long life. With the lower cost of LED spotlights, LED lighting applications are gradually begun to spread. In current stage, LED spotlights mainly as an alternative to traditional halogen-based, mostly refer to the relevant safety requirements of traditional lighting requirements, and according to the characteristics of LED lights, the formation of a safety certification standards. Currently, certification of LED spotlights, international European CE and UL certification in North America is the major, mainly in China can be voluntary certification (CQC). Current LED spotlights main optics (lens, reflector), LED light, radiator, mask, cap these parts.
First, we discuss LED spotlights optics (lens, reflector), divided into 30 degrees and 60 degrees two kinds. We can select different angles spotlights size according to their different purposes, the illuminated area, and irradiated site.
The follow is the LED spotlight light source, which is chips, LED lamps heart. Chips are generally divided into three types: red, green, blue (white light produced raw materials). Which blue chip is also known as sapphire, is currently the best LED chips. Further down is the electrode, play a very important role in the LED light source, the power of conduction, LED chip power loss is related to the conductive metal used. Generally on the market aluminum is used more common, some copper conductor metal, and the best conduction strongest performance is 99K gold electrode current, with lowest power consumption, can promote the life of the LED chip.
Then is the light body and face mask of LED spotlights. Currently the best LED light body material is ceramics, so you can ensure the heat LED luminary generated can pass out timely to ensure that within the LED lamps life, it is not easy damage because the too high heat.
Last is the LED spotlights cooling, the material determines the cooling effect of LED lamps, most manufacturers use aluminum radiator materials, organic processing and molding and other means. In the structural design, the manufacturers in order to increase the cooling capacity of spotlights, usually adopt fin approach. A good heat sink can effectively improve the LED life.
