COB Light Source Difference

It is best to choose an electronic ballast in the ballast, because the electronic ballast has the characteristics of improving the light effect and life of the lamp. At present, all the fluorescent light sources on the market must have a ballast to ignite. From the analysis of the number of chip work and the integrated density of the chip, it is found that the integrated packaging multi -chip white light LED knot temperature increases with the increase of the number of integrated chips. Its luminous efficiency has decreased with the increase of the number of integrated chips, so the number of chips and integrated density are also an important influencing factor in the application of integrated packaging technology. Cob package“COB light source module→LED lamps”, You can directly encapsulate multiple chips on MCPCB on the metal -based printing circuit board, and directly dissipate the heat through the substrate to save LED packaging costs, light engine module production costs, and secondary lighting costs. In terms of performance, through reasonable design and microscopy, the COB light source module can effectively avoid the disadvantages of light and glare exist in the combination of separation light source devices; it can also effectively improve the color of the light source by adding appropriate red chip combinations sex. The role of COB light source is to bring instantaneous start voltage and stable voltage to the light source. It can be seen that the quality of the ballast will directly determine the life and light effect of the lamp directly. In addition to the volume, the LED light source also has the advantage of long life. This is also the biggest advantage. The faster speed of the light bulb is attenuation, but the speed is slow. From the aspects of the use of various lamps, COB light sources are mainly used for indoor lighting fixtures such as LED downlights, LED ceiling lamps, etc. Its maximum single watt count will not exceed 50W. Integrated high -power light sources are mainly used for road lighting and industrial lighting fixtures such as solar street lights, LED light lamps, LED street lights, LED industrial and mining lights. SMD slowly replaces HP light sources. HP light sources are currently applied to outdoors. COB still has some places that need to be improved. MCOB is currently not promoted in the existing stage. Cooperation to launch than the current COBoptical parts (aluminum or PMMA village materials, etc.). At present, the size of the COB light source is not fully standardized. When COB light sources are 10,000 hours, the brightness can reach 70%to 80%of the initial brightness, and the traditional light bulb light source has been replaced twice in this use time. After all, the traditional light source can only use 4000 hours of brightness. Only half of the initial brightness is less than half of the selection of this free LED light source. The COB light source can be simply understood as a high -power integrated surface light source. The outlet area and shape size of the light source can be designed according to the product shape structure. As a strategic emerging industry in my country, semiconductor light. However, in the field of special LED light sources, due to the high technical threshold, the market has been monopolized by foreign companies. Semiconductor lighting is a technological revolution in this century. From the perspective of technical maturity, it is still a baby. Although LED high -power white light technology has developed rapidly, the three lives in LED light decay, heat dissipation, and cost are still LEDs. Tiger Tiger, the popularization and development of lighting. COB light source COB (CHIP on Board) is to fix the chip through the silver glue on the substrate, and the electrical connection method of the chip and the substrate is implemented.
