Independently developed and designed a metal bolt type high-power LED light source. In order to improve the stability of the product, we use high-quality LED light-emitting chips imported from the United States. The LED light-emitting chip is directly encapsulated on the top of the metal bolt nut, and the LED metal bolt is directly screwed on the aluminum heat sink during product assembly. Therefore, the LED and the radiator are effectively integrated closely, and the current situation of traditional high-power LED light sources using thermal silica for heat conduction is changed, and the heat transfer efficiency between the LED and the aluminum radiator is greatly improved, effectively ensuring The service life of the LED light source is greater than 60,000 hours. At the same time, high-quality Taiwanese phosphors are used to make a single LED brightness above 80 lumens; and there are a variety of color temperatures to choose from, which can meet the needs of different color temperatures in different occasions.
