Abstract: This paper introduces the led light market point light source and the surface light source coexistence, analyzes their advantages and disadvantages, impact on the lighting market, while the trend in the use of led lighting manufacturers regard these two sources were analyzed
1.Overview
Now on the market for LED light sources in the form mainly divided into two categories, one is a combination of multiple chips directly encapsulated COB integrated light source, the other one is a single LED light source patch made by the PCB posted sided light.
2.Light source characteristics
Two light sources in the form of advantages and disadvantages. For COB integrated light source, the light-emitting surface of the small, light is more concentrated, packaged in a standard LED stent, the high cooling requirements; especially high sealing requirements on the structure of the three anti LED lamps, explosion-proof LED lamps require special treatment, in order to ensure life.
Advantages posted sided light source is respectively uniform, wide illumination area, according to the LED chip cooling requirements, more convenient to expand the size of the aluminum substrate to ensure LED light source life; but the same power source, the light source than the patch COB integrated light source Dimensions several times larger, so the shape of the lamp will increase, especially in both explosion-proof LED lighting industry, the lighting becomes more bulky, which for many lighting manufacturers manufacturing costs made the test, which is the LED lighting industry, especially It is the use of COB mining lamp light causes.
3.Development Direction
COB light source technology has been provided, and constantly improve the business process, product quality and meet the requirements of. As we further enhance the awareness of product quality, many manufacturers have introduced a SMD LED light source products, many users have begun to choose SMD LED light source products. We now introduce the BZD series of explosion-proof LED lamp is compatible with these two light sources, so that our customers more convenient selection, installation.?
