Abstract
The invention discloses an anti-glare reflector mainly comprising a lower light control portion and an upper expanded portion. A lower end opening of the expanded portion is larger than an upper end opening of the light control portion in radius. The anti-glare reflector is applied to directional lighting sets such as down lamps, spotlights, track lamps, underground lamps and wall lamps. After being reflected by the sidewall of the light control portion, light from a light source directly emerges out of the upper end of the expanded portion, and no glaring condensed light spots occur to the opening of the reflector. Therefore, the problem that the light in the traditional reflector intersects twice and glares is solved, and lighting range of the lighting sets can be widened.
Description
Technical field
The field of illuminating lamps that relates to of the present invention, particularly relates to the reflector with anti-dazzle function.
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 the reflector with anti-dazzle function, 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:
A reflector with anti-dazzle function, the intracavity sidewall of described reflector comprises the control light part of bottom and the flared portions on top, and the lower surface opening radius of described flared portions is greater than the opening radius of the upper surface of control light part.
As the improvement of technique scheme, the middle part of described reflector is provided with step portion, and described control light part, step portion, flared portions successively transition link into an integrated entity.
Further, described step portion is provided with for absorbing from the light-absorption layer of the light of glass cover-plate reflection.
Another kind as technique scheme improves, and the middle part of described reflector is overhanging portion.
As the improvement of technique scheme, the upper port edge of described flared portions is provided with flanging, and described flanging is provided with light-absorption layer.
Further, described light-absorption layer is circle extinction rete or a light-absorbing coating.
The invention has the beneficial effects as follows: the reflector with anti-dazzle function that the present invention adopts, it is applied in the directional type lightings such as Down lamp, shot-light, track lamp, underground lamp, wall lamp, the light sending from light source is after the sidewall reflects of control light part, the direct upper surface outgoing from flared portions, 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.
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 the reflector structural representation of the embodiment of the present invention one;
Fig. 3 is that the reflector of the embodiment of the present invention one is arranged on the profile in light fixture;
Fig. 4 is that the reflector of the embodiment of the present invention two is arranged on the profile in light fixture.
The specific embodiment
Embodiment mono-
With reference to Fig. 2 and Fig. 3, a kind of reflector with anti-dazzle function of the present invention, the intracavity sidewall of described reflector comprises control light part 11, the step portion 12 at middle part and the flared portions 13 on top of bottom, and the lower surface opening radius of described flared portions 13 is greater than the opening radius of the upper surface of control light part 11, and described control light part 11, step portion 12, flared portions 13 successively transition link into an integrated entity.By this reflector device in light fixture time, the light that LED light source 2 sends through the light path of reflective cup reflects as shown in phantom in Figure 3, light is after the inwall primary event of control light part 11, directly shine outside the open end of flared portions 13, 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.
Because 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 present embodiment is provided with for absorbing from the light-absorption layer of the light of glass cover-plate 3 reflections in described step portion 12.
In addition, the upper port edge of described reflector is provided with flanging 14, and the light part reflecting due to glass cover-plate 3 also can form dazzles in flanging 14 edges, so the present embodiment is provided with light-absorption layer equally at flanging 14 places.
In the present embodiment, described light-absorption layer is circle extinction rete or a light-absorbing coating.Described extinction rete or light-absorbing coating all adopt light absorbent, utilize light absorbent to absorb from the light of glass cover-plate 3 reflections, effectively prevent dazzle.
Embodiment bis-
With reference to Fig. 4, another kind of the present invention has the reflector of anti-dazzle function, described reflector comprises device in the control light part 11 of light fixture bottom and installs the flared portions 13 on light fixture top, and the lower surface opening radius of described flared portions 13 is greater than the opening radius of the upper surface of control light part 11, described control light part 11 and flared portions 13 are separately fixed in light fixture, and the middle part of described reflector is overhanging portion.From the light of glass cover-plate 3 reflection of light fixture, can inject control light part 11 rears from overhanging portion, therefore can not produce dazzle, the anti-dazzle effect reaching is identical with embodiment mono-.
In embodiment bis-, the upper port edge of described flared portions 13 is provided with flanging 14 equally, and described flanging 14 is provided with light-absorption layer.Described light-absorption layer is circle extinction rete or a light-absorbing coating.
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.
