Abstract
An LED reflection cup a horn-mouth-shaped cup body, an installation clip on the external of the horn-mouth-shaped cup body, a reflection and refraction surface on the inner side, and a light source aperture site on the upper center part, wherein the reflection and refraction surface is a stepped reflection layer. By designing the reflection and refraction surface into a stepped reflection layer, the light rays are easily controllable via reflection of stepped reflection layer, the light distribution requirement for actual lighting can realized easily. Gradual transition of illumination brightness from center to periphery ensures an excellent lightning effect and wider lighting scope, and realizes directional lighting for roads and in tunnels. Moreover, stepped reflection layer is more flexible for light distribution and the sizes of the reflection layer steps can be designed based on the requirement of the actual light distribution curve thereby improving effective utilization rate of total light flux of light fixture and uniformity of light rays on a road surface. The LED reflection cup has the advantages of simple structure, easy manufacture and pleasing appearance.
Description
Technical field
The utility model relates to a kind of lamp fittings, particularly a kind of LED reflector.
Background technology
Along with the maturation of led chip and packaging technology, energy-saving and environmental protection, life-span length are the distinguishing features of LED at present, and the LED solid-state illumination has become current trend.In application facet, particularly aspect road and tunnel illumination, in order to strengthen illuminating effect, secondary optics is the important embodiment of LED light fixture performance, as long as it has two kinds of forms, be lens and reflector, wherein reflector is than the light utilization efficiency height of lens, but control relative difficult for light, and the reflector of prior art, generally being that side is provided with reflective plane or arc reflector layer within it, is the Chinese patent disclosed a kind of " module type LED street lamp reflecting cup " of ZL200810219771.4 as the patent No., and its reflector layer has adopted the said structure form exactly, but still there is very big difficulty in this reflector layer for the control of light, be difficult to realize actual illuminating light distribution requirement, the effective rate of utilization of light fixture total light flux is not high enough, and illuminating effect is not ideal enough.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems and deficiency, provides a kind of light control easily, can realize actual illuminating light distribution requirement like a cork, and simple in structure, good illumination effect, LED reflector that illumination zone is wide.
The technical solution of the utility model is achieved in that LED reflector described in the utility model, comprise loudspeaker cup body and be arranged on the installation card base in the loudspeaker cup body outside, the reflective plane of refraction of inboard and the light source hole position of upper middle position, be characterized in that described reflective plane of refraction is the stairstepping reflector layer.
In order to improve reflectivity, make illuminating effect of the present utility model better, the inner surface of above-mentioned stairstepping reflector layer is coated with the aluminium film.
In order to make the utility model structure varied, above-mentioned loudspeaker cup body can be the cup body of rectangular horn cup body or cylindrical cup body or triangle cup body or other shape.
The utility model is because employing is arranged to the stairstepping reflector layer to reflective plane of refraction, reflection by the stairstepping reflector layer, not only light control easily, can realize actual illuminating light distribution requirement like a cork, and illumination brightness meeting is by the transition of middle mind-set periphery gradual change type, make the good illumination effect of light fixture, illumination zone is wide, realize directional lighting easily to highway and tunnel, and the stairstepping reflector layer has luminous intensity distribution flexible design more, make it require to design the reflector layer step size, thereby improve the effective rate of utilization of light fixture total light flux and shine the uniformity of the light on road surface according to the illuminating light distribution curve of reality.Simultaneously, can plate the very thin aluminum membranous layer of one deck by vacuum aluminum-coated membrane process, make reflector layer have higher reflectivity, thereby improve the illuminating effect of light fixture further at the inner surface of stairstepping reflector layer.And loudspeaker cup body can be arranged to rectangular configuration, thereby makes hot spot present rectangle, helps enlarging illumination range like this.Advantages such as that the utility model also has is simple in structure, easily manufactured, good looking appearance.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is a polycrystalline substance schematic diagram of the present utility model.
The specific embodiment
As Fig. 1-shown in Figure 2, LED reflector described in the utility model, comprise loudspeaker cup body 1 and be arranged on the installation card base 2 in loudspeaker cup body 1 outside, the reflective plane of refraction 3 of inboard and the light source hole position 4 of upper middle position, in order to make light control easily, can realize actual illuminating light distribution requirement like a cork, thereby make the good illumination effect of light fixture, illumination zone is wide, simultaneously in order to make luminous intensity distribution more flexible, make it require to design the reflector layer step size according to the illuminating light distribution curve of reality, described reflective plane of refraction 3 is set to the stairstepping reflector layer.Wherein, card base 2 is installed is can be barb-shaped structure, and be provided with two, and be symmetricly set on the both sides of loudspeaker cup body 1.And in order to improve reflectivity, make illuminating effect of the present utility model better, the inner surface of above-mentioned stairstepping reflector layer is coated with the aluminium film, and this aluminum membranous layer plates by vacuum aluminum-coated membrane process, and the aluminium film thickness is even, and reflecting properties is good.In order to make the utility model structure varied, above-mentioned loudspeaker cup body 1 can be the cup body of rectangular horn cup body or cylindrical cup body or triangle cup body or other shape.
The utility model is described by embodiment, but the utility model is not construed as limiting, with reference to description of the present utility model, other variations of the disclosed embodiments, expect easily that as professional person such variation should belong within the utility model claim restricted portion for this area.
