Abstract
The invention discloses a reflection cup used for an anti-glare lamp. The reflection cup is horn-shaped, and the inner wall of the reflection cup is a reverse parabolic face. Light generated by a light source is directly emitted to the outside of an opening end face of the reflection cup after primary reflection by the inner wall of the reflection cup and cannot form glaring hotspots at an opening of the reflection cup, so that the problem of glaring generated by secondary intersection of light in conventional reflection cups is solved, irradiating range of a lighting lamp can be expanded.
Description
Technical field
The present invention relates to field of illuminating lamps, particularly relate to a kind of reflector for anti-glare lamp.
Background technology
The light fixtures such as Down lamp, shot-light, track lamp, underground lamp, wall lamp all belong to the directional type lighting that is provided with reflector, have that light is relatively concentrated, lumen value high.Along with LED lighting engineering is updated, the light extraction efficiency of LED improves constantly, and LED becomes the principal light source of this class light fixture gradually at present.Yet because the volume of LED own is little, brightness is high, makes its glare problem also more serious.
The reflector of prior art please refer to Fig. 1, common reflector inwall is generally parabolic surface at present, adopt the reflector of this structure, shortcoming is that the light of light source can intersect after reflector inwall secondary reflection on reflector opening, thereby in light-emitting area, form dazzling focal point, easily to people, cause dizzy sensation.For solving the glare problem of light fixture, prior art be everlasting be equiped with on light fixture can anti-dazzle cloudy surface cover, but cloudy surface cover can reduce the brightness of illumination of Down lamp again.
Summary of the invention
The deficiency existing for prior art, the object of the present invention is to provide a kind of reflector for anti-glare lamp, by this reflector, can prevent that light secondary from intersecting, and reaches the effect of anti-dazzle.
The technical solution used in the present invention is:
For a reflector for anti-glare lamp, described reflector is horn-like, and the inwall of described reflector is anti-parabola face.
Improvement as technique scheme; for existing directional type light fixture, conventionally can on light fixture, be provided with the glass cover-plate for waterproof and dustproof and protection light source; the light portion of LED light source outgoing still can produce dazzle after glass cover-plate reflection; for addressing this problem, the inwall of described reflector middle part is provided with for absorbing from the light-absorption layer of the light of glass cover-plate reflection.
As the improvement of technique scheme, the upper port edge of described reflector is provided with flanging, and because the light of glass cover-plate reflection partly can be in the formation dazzle of flanging edge, therefore described flanging is also provided with light-absorption layer.
As the improvement of technique scheme, described light-absorption layer is a circle light-absorbing coating.
As the improvement of technique scheme, described light-absorption layer is a circle extinction rete.
The invention has the beneficial effects as follows: a kind of reflector for anti-glare lamp that the present invention adopts, this reflector is horn-like, the light that light source produces is after the inwall primary event of reflector, directly shine outside the open end of reflector, can not form dazzling focal point at reflector opening part, thereby solved light secondary in traditional reflective cup, intersect the problem that produces dazzle, and can increase the range of exposures of lighting.In addition, due to the glass cover-plate of existing light fixture also can reflecting part outgoing light, produce dazzle, so the present invention is respectively equipped with light-absorption layer at inwall middle part and the flanging of reflector, by light-absorption layer, absorb from the light of glass cover-plate reflection, effectively prevent dazzle.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the invention will be further described.
Fig. 1 is the structural representation of the reflector of prior art;
Fig. 2 is structural representation of the present invention.
Fig. 3 is that reflector of the present invention has been installed the generalized section after LED light source.
The specific embodiment
With reference to Fig. 2 and Fig. 3, a kind of reflector 1 for anti-glare lamp of the present invention, described reflector 1 is horn-like, and the inwall of described reflector 1 is anti-parabola face.When this reflector 1 is arranged in light fixture, the light path that the light that LED light source 2 sends reflects through reflector 1 as shown in phantom in Figure 3, light is after the inwall primary event of reflector 1, directly shine outside the open end of reflector 1, can not form dazzling focal point at reflector 1 opening part, thereby solved light secondary in traditional reflective cup 1, intersect the problem that produces dazzle, and can increase the range of exposures of lighting.
Existing directional type light fixture can be provided with the glass cover-plate 3 for waterproof and dustproof and protection light source conventionally on light fixture; the light portion of LED light source 2 outgoing still can produce dazzle after glass cover-plate 3 reflections; for addressing this problem, the inwall of described reflector 1 middle part is provided with for absorbing from the light-absorption layer 4 of the light of glass cover-plate 3 reflections.In addition, the upper port edge of described reflector 1 is provided with flanging 11, and because the light of glass cover-plate 3 reflections partly can be in flanging 11 edges formation dazzles, therefore described flanging 11 is also provided with light-absorption layer 4.Described light-absorption layer 4 is a circle light-absorbing coating or extinction rete.Described light-absorbing coating or extinction rete are light absorbent, utilize light absorbent to absorb from the light of glass cover-plate 3 reflections, effectively prevent dazzle.
The above, be preferred embodiment of the present invention, and the present invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
