Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional view in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
As shown in drawings: a kind of LED down radiator, comprise cylindrical shell 4 and fin 5, fin 5 circumferentially distributes on cylindrical shell 4 lateral surface, the lateral surface of cylindrical shell 4 is provided with multiple supporting structure 6 swung, fin 5 is arranged on supporting structure 6 respectively, the maximum amplitude of oscillation of supporting structure 6 is less than the distance between adjacent two supporting structures 6, and the swaying direction of all supporting structures 6 is consistent; Cylindrical shell 4 is the cylinder of hollow structure, has a cavity 4-4 in the solid construction of cylindrical shell, and be provided with a small machine 7 in cavity 4-4, small machine 7 is provided with temperature signal inductor 8, and lead-out wire 2 end of small machine 7 is connected to controller 1; The upper bottom surface of cylindrical shell 4 is provided with LED lamp panel installing hole 4-2, a groove 4-1 is provided with near one of them installing hole, be provided with temperature sensor 3 in groove 4-1, the height of temperature sensor 3 is less than the degree of depth of groove 4-1, and the bottom surface of cylindrical shell 4 is provided with small machine and draws string holes 4-3.
The surperficial undulate structure of fin 5, can increase the area of dissipation of fin 5, be beneficial to the raising of rate of heat dispation.-
The early warning temperature of temperature sensor 3 is 50 DEG C, when the temperature of temperature sensor 3 is more than 50 DEG C, temperature signal inductor 8 just orders about small machine 7 and carries out work, and small machine 7 drives bracket institution 6 that fin 5 is swung back and forth to carry out quick heat radiating, makes temperature near LED lower than 50 degrees Celsius.
The amplitude of oscillation of controller 1 adjustable support structure 6 and hunting frequency, can select the suitable amplitude of oscillation and hunting frequency according to actual conditions, not only reached heat radiation object but also economy.
Cylindrical shell 4 adopts fine copper material to make, and fin 5 adopts fine aluminium material to make, and makes cylindrical shell 4 and fin 5 all have good heat conduction and radiating effect.
Supporting structure 6 all scribbles silicone grease with the junction of cylindrical shell 4 and the junction of supporting structure 6 and fin 5, strengthens the heat conduction rate of each junction.
Operation principle of the present utility model and using method are: LED lamp panel be arranged in the installing hole 4-2 on cylindrical shell 4 upper bottom surface, when LED lamp panel is just started working, temperature near lamp plate is lower, when temperature sensor 3 in groove 4-1 does not reach early warning value, small machine 7 is in off working state, now fin 5 is still on bracket institution 6, and now fin 5 dispels the heat slowly, when after LED lamp panel work a period of time, temperature near lamp plate can sharply raise, when temperature sensor 3 senses that the temperature of lamp plate exceedes early warning value, temperature sensor 3 can produce a kind of signal, after this signal is accepted by the temperature signal inductor 8 on small machine 7, small machine 7 can be ordered about start working, under the drive of small machine 7, heat radiation is accelerated in the swing that bracket institution 6 drives fin 5 to carry out left and right, because the swaying direction of all supporting structures 6 is consistent, and the maximum amplitude of oscillation of supporting structure 6 is less than the distance between adjacent two supporting structures 6, so the phenomenon that there will not be fin 5 mutually to collide occurs, now fin 5 dispels the heat fast, the temperature near LED lamp panel is forced to drop to less than 50 DEG C fast, and make the temperature at LED lamp panel place maintain 50 DEG C all the time once, thus can ensure that the temperature at LED lamp panel place can not be too high, LED lamp panel is made to have longer normal service life, temperature near LED lamp panel is lower to be got off suitably to be reduced the amplitude of oscillation and the hunting frequency of supporting structure 6 by controller 1 later, and then suitably reduce rate of heat dispation, reach energy-conservation object, also can suitably increase according to the size of LED lamp panel heat production power or reduce the amplitude of oscillation and the hunting frequency of supporting structure 6 in addition, to reach the object of quick heat radiating.
