Goldsuno LED Bulb Heat-dissipation Solution
2013-03-08 | Hits:90 | Print


 
LED bulb thermal problem solving bad affect lamp life, LED drive power, the operating temperature of the drive power generally can not be higher than 60 ° C, but the structure of the LED bulb decided to drive power can only be builtThis requires that the lamp structure to ensure that the low light fades and the overall life of the lamps have good heat transfer, thermal conductivity and thermal path. All currently available LED ball bubble more than 6063 the car aluminum and die-cast aluminum for heat dissipation and shell, from the thermal conductivity, thermal conductivity of 6063 about 190 die-cast aluminum about 150, 6063 the car aluminum fabrication process for picking up profiles cutting lathe whittled lamp body, the profile groove Article calories mutual radiation area, but the effect is not completely play. Die cast housing processing methods, mass production faster than the cars aluminum, good economic returns, but due to poor heat transfer, plus the shell can not oxidation treatment, the appearance of dealing with only paint, paint molding thermal resistance, the impact of heat. Shorter life expectancy of the LED and power, fine Scienward R & D engineers With many years of experience in metal processing using pure aluminum is enclosure cooling materials, pure aluminum thermal conductivity of 230 high-quality thermal materials, processed into a variety of housing by stamping, surface treatment for oxidation, and an auxiliary conduction and thermal liner carefully designed, so that by LED fever timely, balanced passed to the shell disperses into the housing and aluminum PCB following the use of pure aluminum stamping and increase cooling liner, so the LED PN junction temperature 5-10 ° C lower than similar products, the heat transfer to the enclosure 5 minutes faster than 6063, 10 minutes faster than the die-cast aluminum, our products bubble comparison with similar products die casting ball at the Beijing solar Energy Research Institute, Division I two minutes the temperature reaches equilibrium state, die-casting LED bulb takes 10 minutes to reach the temperature peaceful.
