Relevant knowledge and analysis of LED lamp beads

LED lamp beads are widely used in many production fields, such as lighting, LED large screen display, traffic lights, decoration, computers, electronic toys and gifts, switches, telephones, advertisements, urban brilliance projects, etc. The most common LED lamp beads are plug-ins and SMD patches. The plug-in LED low-power specifications include: straw hat/helmet, round head, concave, oval, square (2 * 3 * 4/2 * 5 * 7) bullet head, flat head, (3/5/8/bread type) piranha, etc. SMD patches are generally divided into 3535/3528/5050 and other front light sources, and 1016/020 and other side light sources.
Mercury in CCFL backlight is a kind of substance that does great harm to the environment, but LED backlight does not contain this harmful substance. You should know that the global total output of monitors reached 220 million in 2009. If LED backlight displays become popular in the future, it will greatly help improve the earth's environment.
Because the white light emitted by the LED backlight module is more pure than that of the traditional CCFL, the display with LED backlight is easier to improve the color gamut. The improvement of color gamut can make the display display display more colors and make the color performance better. Theoretically, LED backlight has longer life and longer brightness attenuation cycle than CCFL backlight. Benefiting from the cost advantage and the rapidly expanding market of LED application products, the domestic packaging industry has achieved sustained and rapid growth. At present, it has formed a certain industrial scale and become an important LED packaging production base in the world, and has initially formed four LED industry intensive regions in the Pearl River Delta, the Yangtze River Delta, Fujian, Jiangxi and the Bohai Rim.
