The specific embodiment

For the utility model is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.

The automobile-used high-power LED lamp schematic diagram of portable lighting that Fig. 1 provides for the utility model, described high-power LED lamp comprises high-power LED substrate 3, LED substrate 3 is to be formed by the fixing encapsulation of many high-capacity LED fluorescent tubes, by screw, LED substrate 3 is assemblied on LED lamp radiator 2, if desired, can between LED substrate 3 and LED lamp radiator 2, be coated with one deck thermal grease.Like this, guarantee that the heat that LED produces can successfully be transmitted on the blade of LED lamp radiator 2, guarantee that LED is under the long-time operating mode using, the heat of generation can fully effectively dissipate.

LED lamp radiator 2 adopts A360 pack alloy, this aluminium alloy has good thermal diffusivity, and surface adopts chromating to process or oxidation processes, when this processing method can guarantee that product uses out of doors, prevent corrosion, effectively reduce the impact of the heat radiation of surface corrosion on aluminium alloy.This radiator surface area reaches 0.75 square metre, thereby guarantees heat radiation fully.

The first sealing ring 1, adopts the silica gel of resistance to 200 ℃ of high temperature to make, for the assembling space between sealing LED lamp radiator 2 and LED lamp housing 19.First the first sealing ring 1 is embedded in the seal groove of LED lamp radiator 2, and then by LED lamp radiator 2 be assembled to the flat openend of LED lamp housing 19, the other end pad radiator stiffener 18 of LED lamp housing 19, then tightens together radiator stiffener 18, LED lamp housing 19 and LED lamp radiator 2 with screw.

LED lamp housing 19 adopts 1060 aluminium sheets to form through multi-drawing, and feature is that intensity is high, lightweight, good heat dissipation, attractive in appearance, plays reflection ray simultaneously and helps the effect of dispelling the heat.

Together with one end of LED lamp housing 19 is equipped in LED lamp holder end die casting 15, between LED lamp housing and LED lamp holder end die casting, pad sealing gasket 5, LED lamp housing 19 inner mast head end aluminium backing plates 17 are strengthened, this head end aluminium backing plate is with 12.7 holes, for threading, on LED lamp holder end die casting 15, have a fairlead, cable seal head 16 is screwed on this hole, for locking electric wire.The other end of LED lamp housing 19 adopts together with same structure is equipped in LED lamp end die casting 6, and unique difference is to only have installing hole on end aluminium backing plate 4, there is no through wires hole, on LED lamp end die casting 6, there is no fairlead.On the side of LED lamp end die casting 6 and LED lamp holder end die casting 15, a double threaded screw 7 is respectively housed.A first nylon spacer 8 of each cover on double threaded screw 7, the hole on support 14 2 limits is enclosed within on double threaded screw respectively, then on double threaded screw, overlaps respectively nylon spacer 8 and metallic gasket 9, finally fixing with hexagon check nut 10.Utilize support 14 lamp can be fixed on to the position needing.In the time unclamping stop nut 10, can rotate lamp body, lamp body is adjusted to after the angle needing, then stop nut 10 is tightened, fixing whole lamp body.

LED lamp housing 19 is provided with 4 leaking holes, and as shown in Fig. 2～Fig. 5, in Fig. 4, A place is leaking hole place partial enlarged drawing, the edge outwardly convex of leaking hole.Guarantee that like this water is difficult for flowing to LED lamp housing, can guarantee that lamp body rotates any angle time, ponding can successfully flow out simultaneously.

On oval safety glass 12, cover has the second sealing ring 13; attach it to again the elliptical openings end of LED lamp housing 19; and fastening with aluminium shroud ring assembly 11; to play good sealing function; reach outdoor water-proof class requirement, the destruction that effectively protection LED substrate 3 is not subject to insect, rainwater, sand, rubble etc. simultaneously.

The automobile-used high-power LED lamp of portable lighting that the utility model provides is according to the feature of LED, in conjunction with the situation of outdoor use.To lamp body done reasonably, optimal design.There is following features:

1) solve the heat dissipation problem of LED from material: lamp radiator adopts A360 pack alloy, and lamp housing adopts 1060 aluminium sheets to make, and these two kinds of materials are all high heat conductance, light-duty material.

2) solve the heat dissipation problem of LED from structure: fansink designs becomes the muscle shape of vertical bar, in increasing surface area, be twoly convenient to circulation of air, radiator surface area reaches 0.75m2.The fitting surface of radiator and LED substrate, after adding by machine, surface smoothness reaches 0.05mm, guarantees to fit tightly with LED substrate, is conducive to heat transmission.

3) on the die casting of two of lamp bodies, a double threaded screw is respectively housed, double threaded screw is through the hole on support, highstrenghtpiston's pad of the each pad in support both sides, and an additional metallic gasket, finally locks with stop nut.Having realized like this lamp body can rotate by 360 degree; If adjust the angle of irradiation, slightly loose nut, rotate lamp body to the angle needing, then fastening nut is fixed.

4) on lamp body in different Position Design 4 leaking holes, while guaranteeing that lamp irradiates to different angles, can guarantee that ponding spills.Meanwhile, the fitting surface of radiator and LED substrate, is designed to the structure of boss, and while guaranteeing up ligthing, ponding can not flow on LED substrate.

5) LED adopts modular designs, is encapsulated on aluminium base.If there is LED particle to damage, only need to change relevant substrate, be the convenience that maintenance provides, also reduce the cost of maintenance simultaneously.
