The specific embodiment
Further describe the specific embodiment of the present utility model below in conjunction with accompanying drawing.
In conjunction with referring to shown in Fig. 1～4, one embodiment of a kind of LED lamp cooling structure of the utility model is provided, it dispels the heat for LED lamp pearl plate 2, comprise radiator 1, described radiator 1 comprises both sides side plate 11 and the middle plate 12 that is connected to side plate 11 middle parts, described both sides, and described middle plate 12 lower surfaces vertically arrange many radiating ribs 13 consistent with described radiator direction extending longitudinally; The outer surface of described both sides side plate vertically arranges many radiating ribs 14 consistent with described radiator direction extending longitudinally; Described lamp pearl plate 2 is located at described middle plate 12 upper surfaces, the light-passing board 3 of light fixture is arranged between described both sides side plate 11 and is positioned at described lamp pearl plate 2 one sides, described radiator structure also comprises the push pedal 4 that is arranged between described both sides side plate 11 and is arranged in described plate radiating ribs 13 1 sides, be fixedly mounted on the air supply device 5 in described push pedal 4, and be fixedly mounted on the end cap 6 at described radiator 1 longitudinal two ends; Described radiator 1, light-passing board 3 and two ends end cap 6 form a light-source chamber 7; Described radiator 1, push pedal 4 and two ends end cap 6 form a heat radiation chamber 8.In an embodiment, lamp pearl plate 2 is directly close to the upper surface of plate 12 in radiator 1, forms a large heat-conducting area, contacts with lamp pearl plate 2 heating faces 100%, thereby can more imitate, the heat of lamp pearl plate 2 is delivered in radiator 1 and is spread; This radiator 1 radiating ribs 13,14 reasonable in design around, makes the area of dissipation of radiator 1 many, and radiator 1 can be to three different directions heat radiations, with existing radiator merely compared with the heat radiation of direction, more can promote circulation of air, accelerate radiating rate, extend the service life of LED lamp.Preferably, the radiating ribs 13 of described middle plate 12 is laterally and is evenly spaced; The radiating ribs 14 of described both sides side plate 11 is vertically and is evenly spaced.By the gap of radiating ribs 13,14 is rationally set, make wind path smoothness in radiator 1, and in conjunction with air supply device 5, in the situation that installing other accessories, fan 51 is dried facing to middle radiating ribs 13, when wind is mobile toward two ends, take away the heat in radiating ribs 13, derive thereby accelerate further heat, realize high efficiency and heat radiation.
The inner side, vertical end of described both sides side plate 11 is respectively equipped with longitudinal square groove 15 that can supply described light-passing board 3 and described push pedal 4 to install, so that location is installed, fastener-free exposes to light-passing board 3 one sides and affects outward appearance; Further, described push pedal 4 is provided with 2, inserts the deep bead that forms an intermediate openings respectively from longitudinal two ends of described square groove 15.This is because this radiator 1 is strip, if when radiator is long, push pedal is only inserted and runs through whole radiator from a side, so during insertion easily because the foozle of parts is stuck; Again because this radiator need to be reserved the ventilating opening that air supply device 5 is set, thereby insert from longitudinal two ends of square groove 15 respectively by two push pedals 4, can adjust flexibly the installation site of air supply device 5, to guarantee the just middle part to heat radiation chamber 8 of ventilating opening of air supply device 5.
The outside, vertical two ends of described both sides side plate 11 is respectively equipped with the longitudinal arc groove 16 that can install for described end cap 6, and further, described end cap 6 has the installing hole 61 corresponding with described arc groove 16, and is fixedly connected with described radiator 1 screw thread.End cap 6 has the effect that stops that light-passing board 3 and push pedal 4 vertically move, and when fixing end cap 6 is installed, realizes fixing light-passing board 3 and push pedal 4.Certainly, between end cap 6 and radiator 1, can also adopt other modes of removably connecting to be fixed.
Described air supply device 5 comprises the shell 52 that is provided with installation foot and the fan 51 that is arranged on described shell 52 inner sides, can make like this fan 51 as far as possible near radiating ribs 13, when blowing, middle plate 12 is to the generation barrier effect of the wind comes from, poor at heat radiation 8 middle parts, chamber and both sides mineralization pressure, and then accelerate the speed air flow in heat radiation chamber 8, effectively improve the radiating effect of radiator.
Described end cap 6 has the wind hole 62 communicating with described heat radiation chamber 8, unblocked to realize radiator wind path.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
