The edge of described Lamp cup enclosing cover is provided with the convex edge, all side projecting slot of Lamp cup enclosing cover.
Described Lamp cup enclosing cover and Lamp cup inner cap adopt the aluminium punch forming.
A kind of LED light fixture that comprises above-mentioned radiator; The LED light fixture lens board that also it comprises substrate, is installed in LED lamp body on the substrate, covers on lens on the LED lamp body, lid is contained in the lens upper surface, be installed in the lamp socket of the outer cover back-end of Lamp cup and be installed in the inboard power supply module of Lamp cup enclosing cover; Described substrate is a layer structure; They are that electronic circuit layer, insulating barrier and aluminum base layer are formed, and described substrate is installed and stated in Lamp cup inner cap following along on the anchor ring.
Be provided with heat conductive silica gel between described substrate and the Lamp cup inner cap.
Described LED lamp body has a plurality of, and they evenly are installed on the substrate.
The invention has the beneficial effects as follows: the present invention adopts Lamp cup enclosing cover and Lamp cup inner cap to adopt the aluminium drawing; And conduct heat to Lamp cup inner cap and Lamp cup enclosing cover in led light source combination, and in Lamp cup, cover the steam vent that is provided with, lamp body is at adstante febre; Can air-flow be introduced in lamp body the place ahead; In Lamp cup enclosing cover and Lamp cup inner cap, form thermal convection current, and add the Lamp cup enclosing cover, Lamp cup is covered with many row's steam vents outward; Can strengthen circulation of air with the Lamp cup enclosing cover, Lamp cup enclosing cover and Lamp cup inner cap heat-sinking capability are provided greatly; And this structure Lamp cup enclosing cover and Lamp cup inner cap can conveniently adopt drawing, and overall structure is comparatively frivolous, and material cost and processing cost are lower.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is the structure chart of Lamp cup enclosing cover of the present invention and Lamp cup inner cap;
Fig. 2 is the three-dimensional exploded view of lamp body of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
Shown in Fig. 1-2; The radiator of a kind of LED light fixture disclosed by the invention; Radiator constitutes the main casing of LED light fixture, and described radiator comprises Lamp cup enclosing cover 1 and Lamp cup inner cap 2, in Lamp cup enclosing cover 1 lower end is provided with the ring-type of mounting lamp holder along 11; Be provided with the ring-type outer 12 of the evagination that Lamp cup inner cap 2 is installed in Lamp cup enclosing cover 1 upper end; On all sides of Lamp cup enclosing cover 1, be provided with many group steam vents 13, be provided with in the lower end of Lamp cup inner cap 2 the interior along anchor ring 21 of lamp substrate 3 is installed, be provided with the outer anchor ring 22 of overlap joint in Lamp cup inner cap 2 upper ends in the ring-type outer of Lamp cup enclosing cover 1; Outer anchor ring 22 width of Lamp cup inner cap 2 are greater than the ring-type outer 12 of lamp body enclosing cover 1, and anchor ring 22 inboard circular row are provided with steam vent 23 in the outer.When cooperate installing, Lamp cup inner cap 2 is directly installed on the ring-type outer 12 of Lamp cup enclosing cover 1, can directly substrate 3 be installed in Lamp cup inner cap 2 upper ends during use, in order to reach higher conducting effect, can heat conductive silica gel be set at Lamp cup enclosing cover 1 and Lamp cup inner cap 2.
The edge of described Lamp cup enclosing cover 1 is provided with convex edge 15, and convenient like this that Lamp cup enclosing cover 1 and Lamp cup inner cap 2 is spacing, all side projecting slot 14 of Lamp cup enclosing cover 1 can increase radiating effect, and can increase the aesthetic feeling of lamp body.
