As preferably, the bottom of described built-in fitting is provided with threading opening, and the inner ring of threading opening is provided with and the close-fitting waterproof washer of lead.The bottom of described housing is provided with the waterproof terminal of lead, and the threading opening of this terminal and built-in fitting bottom is complementary, so that the lead that will link to each other with the LED lamp passes from built-in fitting.The purpose that waterproof washer is set is better sealing, and anti-sealing infiltrates in the light fixture from threading opening.
As preferably, described built-in fitting is made by aluminum material.Built-in fitting adopts pure aluminum material to make, and has good heat dissipation effect, characteristics that waterproof ability is strong.
As preferably, described housing is made by pure aluminum material, offer one group of strip groove that is parallel to each other on the hull outside wall, form the heat radiation sheet, thereby increased area of dissipation, improved thermal diffusivity, dwindled the volume of light fixture under the identical area of dissipation simultaneously, make that light fixture integral body is smaller and more exquisite, reduced cost; Adopt pure aluminum material to make housing,, thereby improve its service life also in order to improve its thermal diffusivity.
As preferably, described euphotic cover also is provided with waterproof washer by constituting with the metal framework of housing bolting and the luminous plaque that is arranged in the metal framework between described metal framework and the luminous plaque.
As preferably, described metal framework is made by stainless steel material, and described luminous plaque is made by safety glass.The effect of stainless steel upper cover is that ability to bear is strong, outward appearance good, is difficult for getting rusty, and the effect of safety glass is that weight capacity is strong, has better light emission rate as luminous plaque than common acrylic glass; By the purpose that waterproof washer is set is to make the LED light cover have the function of airtight waterproof.
As preferably, described LED lamp comprises several LED lamp sockets that are installed on the aluminium base, the LED lamp socket is provided with the LED particle, LED lamp socket bead is equipped with optical lens, described optical lens is cellular optical lens, by selecting cellular lens for use, make the emergent ray of LED lamp softer, avoided not seeing the road in the place ahead because of the eyeball that can't keep one's eyes open because of strong excessively light makes the pedestrian.
The beneficial effects of the utility model are: by the LED lamp body is provided with in the roomy built-in fitting of memory headroom, not only increased the heat-sinking capability of LED lamp, and the service life of having improved light fixture; 2, adopt aluminium matter lamp housing and aluminium matter built-in fitting,, but also improved water proofing property, bearing not only for the further thermal diffusivity that improves light fixture; 3, on the lateral wall of aluminium matter lamp housing, offer one group of strip groove that is parallel to each other, form the heat radiation sheet, thereby increased area of dissipation, improved thermal diffusivity, dwindle the volume of light fixture under the identical area of dissipation simultaneously, made that light fixture integral body is smaller and more exquisite, reduced cost; 4, adopt stainless steel upper cover and safety glass, can improve the light emission rate of light fixture, make its brightness can illuminate entire wall, have the illumination of high brightness; 5, adopt cellular lens, make the emergent ray of LED lamp softer, avoided strong excessively direct projection fluorescent tube to make the pedestrian not see the road in the place ahead because of the eyeball that can't keep one's eyes open.
