Because existing LED Down lamp belongs to the directional type lighting, its beam angle belongs to optically focused, and light is comparatively concentrated, thereby causes light-receiving area less, can't satisfy the daily life demand.

Summary of the invention

More concentrated for the light that solves existing LED Down lamp, cause technical problems such as light-receiving area is little; Technical problems such as the utility model provides a kind of LED Down lamp, and it is more concentrated that this LED Down lamp can effectively solve led light source, and light-receiving area is less.

For solving above technical problem, the technical scheme that the utility model is taked is a kind of LED Down lamp, it includes illuminating module and astigmatic module, and described illuminating module includes substrate and the led light source that is fixed on the substrate of organizing more, and described substrate is fixed on the fin; Described astigmatic module includes a reflector, and this reflector and fin fix; The center that it is characterized in that described reflector is provided with a through hole, in this through hole, be provided with one and be the astigmatic convex lens of the transparent body, the protruding end of this astigmatism convex lens passes in the cavity volume that through hole places reflector, and described substrate and the many groups led light source that is fixed on the substrate place between fin and the astigmatic convex lens.

Further, also be provided with the frosted line on the protruding end of described astigmatic convex lens.

Further, be provided with a mount pad in the described astigmatic convex lens, described led light source places in this mount pad.

Further, described substrate edges place is provided with many group fixing holes and wiring hole, and this fixing hole and wiring hole run through this substrate respectively; Be provided with a cross section in described mount pad bottom and be trumpet-shaped reflexed light ring, roof pressure mutually bottom the mount pad of this reflexed light ring one end and astigmatic convex lens, the other end and substrate be roof pressure mutually; Installing hole on the described substrate and wiring hole place between the endoporus of reflexed light ring and the outward flange and the many groups led light source that is installed on the substrate places in the endoporus of reflexed light ring.

Further, described led light source is the adopting surface mounted LED light source and roundedly uniformly is arranged on the substrate and places between the endoporus of reflexed light ring.

The beneficial effects of the utility model are to add an astigmatic convex lens in reflector, can greatly improve the astigmatic performance of LED Down lamp by this astigmatism convex lens, thereby strengthen light-receiving area, satisfy user's daily life demand.

The specific embodiment

Below in conjunction with accompanying drawing the utility model embodiment is described further:

To shown in Figure 2, the utility model is a kind of LED Down lamp as Fig. 1, and it includes illuminating module 1 and astigmatic module 2, and described illuminating module 1 includes substrate 11 and the led light source 12 that is fixed on the substrate 11 of organizing more, and described substrate 11 is fixed on the fin 13; Described astigmatic module 2 includes a reflector 21, and this reflector 21 fixes with fin 13; For the light that solves existing LED Down lamp more concentrated, cause technical problems such as light-receiving area is little, the center of described reflector 21 is provided with a through hole 211, in this through hole 211, be provided with one and be the astigmatic convex lens 22 of the transparent body, the protruding end of this astigmatism convex lens 22 passes in the cavity volume that through hole 211 places reflector 21, and described substrate 11 and the many groups led light source 12 that is fixed on the substrate 11 place between fin 13 and the astigmatic convex lens 22; One astigmatic convex lens 22 is set in reflector 21 and can effectively improves the astigmatic performance of LED Down lamp, thereby strengthen light-receiving area, satisfy user's daily life demand by it.

In the present embodiment, preferably also be provided with the frosted line on the protruding end of described astigmatic convex lens,, can make the light that gives out more even, soft by setting up mill yarn effect.

In the present embodiment, for further improving the astigmatic performance of LED Down lamp and the installation firmness of led light source, be provided with a mount pad 221 in the described astigmatic convex lens 22, described led light source 12 places in this mount pad 221; Led light source 12 is placed in this mount pad 221, not only can guarantee the dispersion of light, simultaneously, can guarantee that also led light source 12 avoids the corrosion of external substance, improve the service life of LED Down lamp.

In the present embodiment, be heat radiation and the assembling make things convenient for the LED Down lamp and the astigmatic performance that further improves the LED Down lamp, described substrate 11 edges are provided with many group fixing holes 111 and wiring holes 112, and this fixing hole 111 and wiring hole 112 run through this substrate 11 respectively; Be provided with a cross section in described mount pad 221 bottoms and be trumpet-shaped reflexed light ring 23, mount pad 221 bottoms of these reflexed light ring 23 1 ends and astigmatic convex lens 22 are roof pressure mutually, and the other end and substrate 11 be roof pressure mutually; Installing hole 111 on the described substrate 11 and wiring hole 112 place between the endoporus 231 of reflexed light ring 23 and the outward flange and the many groups led light source 12 that is installed on the substrate 11 places in the endoporus 231 of reflexed light ring 23; Reflexed light ring 23 is blocked above fixing hole 111 and wiring hole 112, not only can guarantee the overall appearance of LED Down lamp, simultaneously, also can improve the brightness of LED Down lamps and the uniformity and the utilization rate of the light in marginal ray source is improved greatly by this reflexed light ring 23, thereby reach the astigmatic performance that improves the LED Down lamp, enlarge light-receiving area.
