Abstract

The utility model provides an LED (light-emitting diode) lamp reflection cup which comprises a reflection cup body. The inner surface of the reflection cup is set into a cambered surface relative to the axis of the reflection cup, the cambered surface is divided into a plurality of small reflection surfaces, and the distance between the cambered surface and the axis of the reflection cup is enlarged along with the distance between the cambered surface and the vertex of the reflection cup. By the aid of the scheme, condensation effects are enhanced by the aid of the small reflection surfaces of the reflection cup, and the use ratio of LED light sources is increased.

Description

A kind of LED lamp reflector
Technical field
The utility model relates to lighting field, refers to a kind of LED lamp reflector especially.
Background technology
LED (Light Emitting Diode), light emitting diode, its basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, uses epoxy sealing all around then, plays the effect of protection internal core.LED is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity.Since the LED lamp comes out, rely on advantages such as its energy-saving and environmental protection, life-span are long, be subjected to attention and the application of numerous industries, be called the 4th generation light source.Though the LED light fixture has been equipped with numerous advantages, it also comes with some shortcomings, as brightness value be not very high, light is relatively dispersed and easily produce problems such as temperatures involved LED quality.For improving this 2 deficiencies, people carry out luminous intensity distribution by reflector is set.LED lamp reflector adopts the optically focused principle, and light emission is gone out, existing LED lamp reflector is owing to the defective in its design, and the effect of optically focused is not satisfactory, therefore, be necessary to propose a kind of new LED lamp reflector, improve spotlight effect, in order to adapt to the needs in market.
The utility model content
The utility model proposes a kind of LED lamp reflector, solved the problem of the bad and dazzle of the radiating effect of LED Ceiling light in the prior art.
The technical solution of the utility model is achieved in that
A kind of LED lamp reflector comprises: the reflector body, and the relative reflector axis of reflector inner surface is the cambered surface setting, and the cambered surface branch is set as some fritter reflective surfaces, and the distance of cambered surface and reflector axis is along with the distance on cambered surface and reflector summit increases and increases.
Further, described cambered surface in axial direction is divided at least three parts, and the arc radius of each several part cambered surface becomes big along the summit gradually to the direction of rim of a cup.
Further, described cambered surface in axial direction is divided into three parts, is respectively first cambered surface, second cambered surface and the 3rd cambered surface, and the arc radius of first cambered surface is 20-24mm, and the arc radius of second cambered surface is 40-48mm, the arc radius 75mm-85mm of the 3rd cambered surface.
Further, described reflective surface is shaped as rhombus.
The beneficial effects of the utility model are: pass through such scheme, by arranging, regulate the radian curvature of the inner surface cambered surface of reflector, make the LED lamp under the effect of reflector, improve spotlight effect, improved the utilization rate of led light source, light is stable, is not prone to hot spot.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the planar structure schematic diagram of an embodiment of a kind of LED lamp of the utility model reflector;
Fig. 2 is the structural representation of looking up of LED lamp reflector shown in Figure 1.
1 is reflector among the figure, and 2 is reflective surface, and 3 is the reflector summit, and 4 is the 3rd cambered surface, and 5 is second cambered surface, and 6 is first cambered surface, and 7 is the reflector rim of a cup.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to the embodiment of Fig. 1 to a kind of LED lamp of the utility model shown in Figure 2 reflector, comprise:: reflector body 1, relative reflector 1 axis of reflector 1 inner surface is the cambered surface setting, the cambered surface branch is set as some fritter reflective surfaces 2, and the distance of cambered surface and reflector 1 axis is along with the distance on cambered surface and reflector summit 3 increases and increases.Described cambered surface in axial direction is divided into three parts, is respectively first cambered surface 6, second cambered surface 5 and the 3rd cambered surface 4, and the arc radius of each several part cambered surface becomes big along reflector summit 3 gradually to the direction of reflector rim of a cup 7.Referring to Fig. 1, reflector 1 height is 34.0mm, and reflector 1 maximum gauge is 55mm.The cambered surface height is 27.9mm, and the arc radius of first cambered surface 6 is 22.4mm, and the arc radius of second cambered surface 5 is 44.5mm, the arc radius 80.7mm of the 3rd cambered surface 4.Led light source is arranged on 3 places, reflector inner surface summit.Pass through such scheme, reflector 1 wall of cup inner surface branch is set as a plurality of cambered surfaces zone, and each zone is divided again and is set as a plurality of fritter reflective surfaces 2, has improved reflecting effect, make that the led light source at 3 places, summit is more even through the light behind reflector 1 optically focused, be not prone to bad phenomenon such as hot spot.
Preferably, described reflective surface 2 is shaped as rhombus, also can be triangle or parallelogram, and the conversion of this structure still falls within the protection domain of the present utility model.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
