The light source module refers to a plurality of LED light sources in a high-power LED lamp, which are integrated into a structure such as light distribution, heat dissipation, waterproof and dustproof IP level, and one lamp is composed of several modules, instead of all the original LED light sources. They are all installed in one fixture. The light source module should have functions such as waterproofing, light distribution, heat dissipation, etc., and it is easy to disassemble and replace.
Liu Muqing, a professor at the Institute of Electric Light Sources of Fudan University, pointed out in the "Shijiazhuang International Semiconductor Lighting Application and Standard Testing Innovation Forum" that the LED street lamp industry after LED light source will go to the road of specialized division of labor, drawing on the experience of high-pressure sodium lamps, the LED street lamp industry chain is concentrated. In the three specialization areas: the light source module, namely the light bulb factory, the drive factory and the street lamp factory, each field has clear specifications, so the specialized division of labor is conducive to the solution of heat dissipation problems, easy to maintain, and promote the LED street lamp industry to continue to move. Standardization.
High Voltage Epoxy Resin Insulator
Insulators can be divided into low-voltage insulators and high-voltage insulators according to different voltage levels. High voltage insulator refers to the insulator used for high voltage and ultra-high voltage overhead transmission lines and substations. In order to meet the needs of different voltage levels, different numbers of single (piece) insulators of the same type are usually used to form insulator strings or multiple insulation poles.
Epoxy resin material has a series of outstanding advantages in organic insulation materials, such as high cohesion, strong adhesion, good flexibility, excellent heat curing performance and stable chemical corrosion resistance. It can be made into various solid materials by vacuum casting through epoxy resin casting system, such as automatic epoxy pressure gel manufacturing process (APG process). The epoxy resin insulation parts made of the epoxy resin have high mechanical strength, strong arc resistance, high compactness, smooth surface, good cold resistance, good heat resistance, good electrical insulation and other advantages, and are widely used in the power industry, mainly playing a supporting and insulating role.
