Solar street lamps light source now basically is to use led light source, and the street lamps in the production process is an important material thermal conductive materials choice, because the choice of solar street lamps and lanterns heat dissipation and thus affecting the service life of led road lighting failure and a
at present, solar street lamps light source is basically led light source, a new type of street lamp is an important material in the manufacture of thermal conductive materials choice, because of the thermal conductive materials selection is the key factors influencing the solar street light heat dissipation, affecting the light of the led street light attenuation and service life. At present, widely used in the production of thermal conductive materials, including thermal conductivity silicone grease, thermal conductivity silicone grease, thermal conductive silicon and graphite thermal conductive materials, solder paste and other traffic light pillar. Among them, the most widely used is the thermal conductivity silica gel. Thermal conductive silicone thermal conductive silicone tablets are silicone base makings, metal oxide and other auxiliary materials, through special process synthesis of a heat conduction medium material. In industry, also known as thermal conductive silicone pads, silicone sheets, soft mat of thermal conductivity, thermal conductivity of thermal conductivity silicone pad, etc. Due to the thermal conductive silicone with high average coefficient of thermal conductivity, thermal conductivity, stable and filling, sealing and heat conduction function of thermal conductivity, therefore is widely used for lighting. Leading thermal silicone piece of the disadvantages of the sol occurs when the temperature is high, resulting in aluminum adhesion between substrate and radiator, not only avoid the heat, but also the heat accumulation. Of course, there is little possibility of this happening. Graphite and solder paste is a new material, the technology is not particularly adult. It is estimated that with the maturity of the technology, it will be widely used in the future. By the way, compared with other indoor led lights, solar street light has a relatively high power. In order to ensure the heat dissipation of lamps and lanterns, prolong the service life of the solar street lamps, using thermal effect good thermal insulating materials - — Thermal conductive silicone is the inevitable choice. This is because compared with other products of thermal conductivity, thermal conductivity silicone performance is more stable, better thermal conductivity, thermal conductivity is mainly used in high-power products, has a slightly sticky, easy to operate, can be directly paste in aluminum plate and the light emitting diode light between the heat sink, strong adhesion, good contact with conducting strip and aluminum plate, discharge the air, through the heat sink will better heat conduction, greatly reduces the heat lamp itself, prolong the service life of the lamp
