Abstract
The utility model relates to a radiating structure of an LED module, comprising parts of a radiator, an LED lamp panel, a silica gel pad, a lens, a pressing plate and the like, wherein the LED lamp panel is provided with a plurality of LED lamps; and a thermal pad is arranged under the lamp panel, and installed in a groove of the radiator together with the lamp panel. The lens is arranged above the LED lamp panel, the middle part thereof is connected and sealed by the silica gel pad, and the LED lamp panel, the silica gel pad and the lens are wholly fixed on the radiator by the pressing plate. The radiating structure of the LED module can ensure that the lamp panel and radiating fins can be contacted effectively, thus having good radiating effect.
Description
Technical field
The utility model relates to a kind of led module radiator structure.
Background technology
The LED lamp can reduce power consumption greatly and increase the service life, and the LED of high brightness receives much concern in recent years; LED is photoelectric device, has only 15%～25% electric energy to convert luminous energy in its course of work, and remaining electric energy nearly all converts heat energy to, and the temperature of LED is raise.In great power LED, heat radiation is a big problem.In led module, adopt the heat dissipation metal substrate usually, mainly contain aluminium base and copper base, copper base is being more much better than aluminium aspect the conductibility of heat, but its cost and weight ratio aluminium are much higher.Current the most frequently used a kind of method is that the LED lamp is welded on the aluminum base PCB, the aluminium base bottom surface is more directly or with heat-conducting silicone grease and radiator combination, make it reach the purpose of heat radiation, this connected mode adopts plane contact, the flatness of contact-making surface will influence radiating effect, in the uneven position of contact, its heat conductivility will be subjected to influencing significantly.
The utility model content
Main purpose of the present utility model is to provide a kind of led module radiator structure of good heat dissipation effect, and simple in structure, with low cost.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of led module radiator structure, comprise parts such as radiator, LED lamp plate, silicagel pad, lens, pressing plate, several LED lamps are installed on the LED lamp plate, heat conductive pad covers under the lamp plate, and in lamp plate is installed in the groove of radiator.Lens are placed on the top of LED lamp plate, and middle the connection with silicagel pad guarantees that sealing, pressing plate are used for LED lamp plate, silicagel pad, lens overall fixed at radiator.
Because the existence of heat conductive pad, and the periphery of lamp plate makes lamp plate effectively contact with fin, thereby can guarantee to have better heat radiating effect all among radiator in the led module radiator structure of the present utility model.The utility model adopts overall structure simultaneously, and excellent sealing performance is arranged, and need not to install additional outer cover again, helps heat radiation more, and makes terminal with compact integral structure attractive in appearance.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments led module radiator structure of the present utility model is described further:
As shown in Figure 1, the led module radiator structure comprises parts such as radiator 1, LED lamp plate 3, silicagel pad 4, lens 5, pressing plate 6; Several LED lamps are installed on the LED lamp plate 3, and heat conductive pad 2 adopts the CNT heat conductive pad, covers the LED lamp plate 3 times, and in LED lamp plate 3 is installed in the groove 11 of radiator 1.Lens 5 are placed on the top of LED lamp plate 3, and middle the connection with silicagel pad 4 guarantees that sealing, pressing plate 6 are used for LED lamp plate 3, silicagel pad 4, lens 5 overall fixed at radiator 1.Radiator 1 offers the groove of two-stage step, and subordinate's groove 11 cooperates with heat conductive pad 2 and LED lamp plate 3, and higher level's groove 12 cooperates with lens 5 and silicagel pad 4, has guaranteed good sealing property; The back of radiator 1 has fin 13, and the rounding processing is carried out in its corner 14.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
