Abstract
The utility model relates to a novel reflective housing of an LED street lamp, which is formed by a fixation frame and a reflective area, wherein the fixation frame is arranged at the outer edge of the reflective area; the reflective area is formed by at least one reflective concave position; a plurality of different total reflection surfaces are arranged on the inner surface of the reflective concave position; a notch is arranged on the bottom surface of the concave position; and LED lamps are arranged on the notch. The novel reflective housing of the LED street lamp provided by the utility model achieves the required light spot and lighting effect in virtue of the secondary optical utilization and distribution realized through the total reflection surfaces, has excellent illumination uniformity, accurate irradiation range, no dazzling light, no radiation and remarkable energy saving effect, simultaneously reduces light pollution, and is energy-saving and environment-friendly.
Description
Technical field
The utility model relates to the LED lighting field, relates in particular to a kind of LED street lamp, more particularly a kind of Novel LED street lamp reflector.
Background technology
Along with the megatrend of energy-saving and emission-reduction, environmental protection, LED obtains application more and more widely with its energy-conserving and environment-protective, luminous efficiency height, long, colour rendering index advantages of higher of life-span.LED is having the trend that replaces conventional road lamp light source (high-pressure mercury lamp, high-pressure sodium lamp and Metal halogen lamp etc.) greatly as a kind of novel solid light source aspect the city illumination light source.
Yet, the luminous of LED street lamp is to be combined by single led light source (finishing the encapsulated LED chip one time), belong to Lambertian source owing to generally be applied to the led light source of street lamp, light emission direction is strong, at distance road surface certain altitude and perpendicular to the road surface when luminous, can only on the road surface, form a less circular light spot, brightness is outwards sharply reduced by the center of circle, illumination uniformity is low, therefore need in addition secondary optics design, make it on the road surface, form a bigger uniform light spots, because have only rectangular light spot could on the road surface, realize seamless link near rectangle, evenly, reach the optimal illumination effect according to full entire road.
Selecting for use lens to carry out the secondary optics design is the most direct effective method, but prior art is often only carried out the outer surface design of lens, and has ignored the design that lens basal plane central authorities are used to place the concave surface (inner headed face) of led light source.Only the lens at outer surface design, limited lens send light direction and light spot shape to LED improvement, can not control the distribution of emergent ray well, thereby make that shining the light spot shape that forms on the road surface keeps off desirable rectangle, and uniformity is not good.
Second deficiency of prior art is the edge that street lamp is installed in road one side when not considering the real road application, but not road central authorities, adopt the prior art of symmetric design just can not play a role in this occasion, because the hot spot that prior art forms on the road surface is all around, a relative street lamp installation site symmetry respectively, and street lamp is in road edge, must have a big chunk light like this and be radiated at outside the road surface, cause the waste of luminous energy, reduce light efficiency.Not only can not address this problem and only tilt to place perfectly, also cause the distortion of road surface light spot shape, changed over trapezoidally by rectangle, make illumination uniformity descend by street lamp cap.For example road lighting requires range of exposures wide on the road bearing of trend, good illumination effect, the angle demand is big, and do not need the illumination of wide region in vertical direction, otherwise both wasted electric energy, optical energy loss is also big, to bad border on every side also causing light pollution, but concerning existing round lens LED, can only reach light intensity by establishing light fixture at bearing of trend, other zones also can be on the low side more, cause the road surface uneven illumination even, directly influence traffic safety.
The utility model content
At the weak point that exists in the above-mentioned technology, the light that the utility model provides a kind of LED of making street lamp can meet the road illuminator distributes, illumination requirement, and the Novel LED street lamp reflector of energy-conserving and environment-protective.
For achieving the above object, the utility model provides a kind of Novel LED street lamp reflector, constitute by fixed frame and retroreflective regions, described fixed frame is arranged at the outer rim of described retroreflective regions, described retroreflective regions is made of at least one reflective recess, the inner surface of described reflective recess is provided with a plurality of different fully reflecting surfaces, and the bottom surface of described recess is provided with a breach, and described breach is provided with the LED light fixture.
Described reflective recess is an irregular structure.
Four angles of described fixed frame are provided with screwed hole, are connected with light cover by screwed hole.
Compared with prior art, the utlity model has following advantage:
A kind of Novel LED street lamp reflector that the utility model provides, carry out the utilization and the distribution of secondary optics by fully reflecting surface, to reach needed hot spot and light efficiency, its illuminance uniformity is good, and range of exposures is accurate, free from glare, radiationless, have obvious energy-saving effect, also reduced light pollution simultaneously, and energy-conserving and environment-protective.

Fig. 2 is the second example structure schematic diagram of the present utility model;
Fig. 3 is the structure schematic diagram of Fig. 2.
The main element symbol description is as follows:
1, screwed hole 2, fully reflecting surface 3, bottom surface
4, fixed frame
The specific embodiment
In order more clearly to explain the utility model, the utility model will be further described below in conjunction with accompanying drawing.
As Fig. 1 and shown in Figure 3, the utility model provides a kind of Novel LED street lamp reflector, constitute by fixed frame 4 and retroreflective regions, fixed frame 4 is arranged at the outer rim of retroreflective regions, retroreflective regions is made of at least one reflective recess, the inner surface of reflective recess is provided with a plurality of different fully reflecting surfaces 2, and the bottom surface 3 of recess is provided with a breach, and breach is provided with the LED light fixture.Reflective recess is an irregular structure, and four angles of fixed frame are provided with screwed hole, are connected with light cover by screwed hole.
More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
