The utility model content:
The purpose of this utility model is to overcome the above-mentioned weak point of existing product, provides a kind of radiating effect better high-powered LED lamp.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of high-powered LED lamp, comprise the lamp housing assembly, LED die set and radiating subassembly, described radiating subassembly comprises heat-conducting plate, first heat sink, second heat sink and heat-pipe radiator, wherein the one side of heat-conducting plate is installed with the LED substrate contacts of LED die set, another side contacts installation with the one side of first heat sink, another surface of first heat sink is provided with several first grooves, the one side of corresponding second heat sink is also offered the second corresponding groove, the evaporator section of described heat-pipe radiator is clamped and fixed between second groove of first groove of first heat sink and second heat sink, and the condensation segment periphery of heat-pipe radiator is provided with radiating fin.
On the upper casing of described lamp housing assembly and lower casing, offer some louvres relative respectively with the radiating fin position.
After the utility model adopts said structure, the heat that produces during high-powered LED lamp work is given heat-pipe radiator by heat-conducting plate conduction in time, the evaporation of absorbing heat fast of the working solution of heat-pipe radiator evaporator section, the temperature of heat-conducting plate and high-powered LED lamp module is reduced rapidly, and gaseous working medium is through the condensation segment motion of inside heat pipe to heat-pipe radiator, heat is conducted to condensation segment, rely on condensation segment and peripheral radiating fin heat radiation thereof, and being cooled to liquid, working medium is back to evaporator section, circulation and so forth forms quick conductive, heat radiation.
The utility model utilizes the fabulous heat conductivility of heat-pipe radiator, the heat diversion that produces when apace high-powered LED lamp being worked, and, the LED module is under the lower temperature environment away from the row heat radiation again of LED module working region part, therefore can prolong the service life of LED module.
