The specific embodiment

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

See also Fig. 1 and Fig. 2, be respectively three-dimensional exploded view of the present utility model and three-dimensional combination figure.The utility model provides a kind of outdoor LED light fixture, comprises a lamp socket 1, a lampshade 2, reaches a protective cover 3; Wherein:

This lamp socket 1 usefulness is provided with on it for a led light source 10, and comprises a substrate 11 and two and be located at interval conducting end 12 on this substrate 11; And in the present embodiment, this led light source 10 is a LED fluorescent tube, just can be electrically connected between two conducting end 12, provides its required electric power after conducting electricity by this two conducting end 12.

The material that this lampshade 2 is a tool light transmission is made, and cooperates substrate 11 shapes of above-mentioned lamp socket 1 and the screen body that forms, is covered in opening part on this lampshade 2 for this substrate 11; For example the substrate in the present embodiment 11 is strip, so this lampshade 2 also is the screen body of a strip.The nib 21 that this lampshade 2 has a shielding part 20 and stretched out by these shielding part 20 peripheries; The inner accommodation spaces 200 that form of shielding part 20 wherein constituting the main covering position of this lampshade 20, and are inserted wherein for the led light source 10 of lamp socket 1.This nib 21 then forms a segment difference section 210 with the inwall of this shielding part 20, described segment difference section 210 and nib 21 formed height falls, thickness greater than aforesaid substrate 11, and be distributed with in these shielding part 20 inwalls and upwards erect a plurality of hollow double-screw bolts 22 that are provided with, with the rough height place (promptly as shown in Figure 3) that trims to described segment difference section 210, after must being flat on the segment difference section 210 for above-mentioned substrate 11, pass this substrate 11 and lock respectively in the hollow double-screw bolt 22 by establish assembly 13 as a plurality of spiral shells such as screws again, make substrate 11 be covered in lampshade 2 tops.

This protective cover 3 also is that the material of tool light transmission is made, and cooperates the external form of above-mentioned lampshade 2 and be placed on outside this lampshade 2, and is equipped with a coaming 30 in 21 of the nibs of this protective cover 3 and lampshade 2.

As shown in Figures 2 and 3, after above-mentioned each assembly assembling is finished, can go up coating one deck heat-conducting medium 14 in substrate 11 surfaces of this lamp socket 1, and the accommodation space 200 of this shielding part 20 is sealed.This heat-conducting medium 14 can be heat-conducting glue or heat-conducting cream, because segment difference section 210 and nib 21 formed height falls are the thickness greater than substrate 11, so can be in order to fill up in

substrate

11 and 21 formed height falls of nib (as shown in Figure 3), must trim height place with the outer surface that makes this heat-conducting medium 14 to nib 21, and, after passing substrate 11 and heat-conducting medium in this lampshade 2, stretch out (promptly as shown in Figure 4) only in order to the power line of led light source 10 required electric powers to be provided.

So,, can obtain the utility model outdoor LED light fixture by above-mentioned contexture.

In view of the above; as shown in Figures 3 and 4; because the main printing opacity position of this lampshade 2 is on shielding part 20; and this shielding part 20 is protected by protective cover 3; reduce problems such as its gloss so can reduce this shielding part 20 to be subjected to the erosion of rainwater, daylight; and more because of this protective cover 3 is placed on outside the lampshade 2, thus also can the appropriateness protective cover 3 that more renew, with the gloss of keeping the light source that the LED light fixture can project and brightness etc.And can provide the effect of waterproof and dustproof by the heat-conducting medium 14 on coaming 30 and the substrate 11, and this heat-conducting medium 14 more has concurrently and helps led light source 10 to carry out thermolysis, with problems such as the waterproof and dustproof that once solves the LED light fixture and heat radiations, more can be applicable to, throw light on outdoors to provide at home as waiting at home outdoor LED lamp installation that outdoor point (as shown in Figure 5) provide the utility model outdoors on the door pillar 40 of door 4 both sides.

Moreover as shown in Figure 6, the led light source 10 that this is located at lampshade 2 inside also can be a LED lamp group, can provide the heat radiation of this led light source 10 required by coating substrate 11 lip-deep heat-conducting mediums 14 so equally.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
