The specific embodiment
With reference to Fig. 1, a kind of LED heat abstractor of the present invention, comprise insulating support 1, described insulating support 1 is made for suitable with the insulation exotic material, be arranged with the heat sink 2 more than two on the insulating support 1, described heat sink 2 is made for the metal material of conductive and heat-conductive, heat sink 2 is divided into positive heating panel that is connected with positive source and the negative pole heat sink that is connected with power cathode, positive heating panel and negative pole heat sink are intervally arranged, between described adjacent positive heating panel and the negative pole heat sink more than one LED3 is installed, but in order to prevent that burning out from appearring in LED 3, the LED number on each group heat sink 2 should keep roughly close degree.
It is more firm for heat sink 2 is installed, described insulating support 1 is divided into upper bracket 11 and lower carriage 12, described heat sink 2 is separately fixed between the upper and lower support 11,12, adopt between described heat sink 2 and the insulating support 1 and peg graft or bolting is connected, thereby make installation and removal all become convenient.In actual use, described insulating support 1 can be made into different shapes such as long strip type, circle as required and need not to change the structure of heat sink 2, even can be made into tabular to insulating support 1, heat sink more than two 2 is pegged graft in its surface, perhaps insulating support 1 is set to one, and heat sink 2 is provided with in the middle.
With reference to Fig. 2, Fig. 3, for LED can conveniently be installed, described heat sink 2 includes panel 21, described panel 21 both sides are extended with left and right side plate 22,22 ' downwards, thereby make panel 21 bottoms form the space of heat radiation, in addition, extend upward the left and right elastic pressure plate 23,23 ' that is useful on clamping LED lamp base respectively in left and right side plate 22,22 ' bottom.LED is convenient to be installed in order to make, and described left and right elastic pressure plate 23,23 ' respectively left, right plate 22,22 ' direction tilt certain angle blocking the lamp base of LED, thereby make LED can directly plug installation.Certainly, in actual use, heat sink 2 also can adopt other Any shape; and LED also can adopt forms such as welding to be connected on the heat sink 2; no matter use which kind of form,, all belong to protection scope of the present invention in a word so long as realize purpose of the present invention with essentially identical means.
With reference to Fig. 3, can accurately locate in order to make LED, on described left and right elastic pressure plate 23, the 23 ' side respectively punching press have several to be used for the slot 24 of LED lamp base location and installation.In order to make the contact area maximum of LED lamp base and slot, the cross section of described slot 24 is the square that is complementary with the LED lamp base, thereby effectively reaches radiating effect.In addition, described slot evenly is distributed on the side of left and right elastic pressure plate, thereby effectively guarantees to have enough cross-ventilations.
