Abstract
The utility model relates to a kind of anti-glare lampshades, it includes the astigmatism cover with the cooperation of the light-emitting angle of LED light, the rib body that a plurality of center from astigmatism cover expands extension around is laid on the astigmatism cover, the cross section that a plurality of rib body is constituted is corrugated.Using the utility model, lamps and lanterns glare problem can effectively solve the problem that, while guaranteeing the illuminating effect of lamps and lanterns to the greatest extent.
Description
Technical field
The utility model belongs to lighting area, more specifically to a kind of anti-glare lampshade.
Background technique
Currently, the anti-dazzle light processing of bulkhead lamp, which is generally used for lampshade or glass surface, reaches anti-dazzle using frosted processing
Effect.However, frosted surface treatment can generally make light efficiency reduce by 20% or more, though meeting the requirement of anti-dazzle, cannot really reach
The requirement of illuminating effect and the light uniformity.
Utility model content
Problem to be solved in the utility model is, provides a kind of anti-glare lampshade, can effectively solve the problem that lamps and lanterns dazzle
Problem, while guaranteeing the illuminating effect of lamps and lanterns to the greatest extent.
In order to solve the above-mentioned technical problem, the utility model provides a kind of anti-glare lampshade comprising with going out for LED light
The astigmatism cover of angular cooperation is laid with a plurality of center from astigmatism cover on the astigmatism cover and expands extension around
Rib body, the cross section that a plurality of rib body is constituted are corrugated.
As the preferred scheme of the utility model, the astigmatism cover is circular cover body.
As the preferred scheme of the utility model, the center of the astigmatism cover is located on the central optical axis of LED light.
As the preferred scheme of the utility model, two adjacent rib bodies are formed by angle at 0 degree to 90 degree
It is gradually increased around in range from the center of astigmatism cover.
As the preferred scheme of the utility model, it is screwed between the astigmatism cover and lamp holder.
As the preferred scheme of the utility model, the cover mouth of the astigmatism cover is equipped with several peaces passed through for screw
Fill hole.
A kind of anti-glare lampshade for implementing the utility model has the following beneficial effects: compared with prior art
The utility model is by the setting of above-mentioned astigmatism cover, and the light that LED light issues is through wavy concaveconvex structure
The reflection and refraction of rib body, make light reach equally distributed effect on astigmatism cover, reduce intermediate region and marginal zone
The light efficiency gap in domain, and then lamps and lanterns glare problem is efficiently solved, while farthest ensure that the illuminating effect of lamps and lanterns.
Detailed description of the invention
In order to illustrate more clearly of the technical solution of the utility model embodiment, the attached drawing of embodiment will be made below simple
Ground introduction.
Fig. 1 is a kind of structural schematic diagram of anti-glare lampshade provided by the utility model；
Fig. 2 be in the structure shown in Fig. 1 A-A to sectional view；
Fig. 3 is the sectional view of B-B direction in the structure shown in Fig. 1.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1 to Figure 3, the preferred embodiment of the utility model, a kind of anti-glare lampshade comprising with LED light
The astigmatism cover 1 of light-emitting angle cooperation, is laid with a plurality of center from astigmatism cover 1 on the astigmatism cover 1 and expands around
The rib body 2 of extension, the cross section that a plurality of rib body 2 is constituted are corrugated.The utility model passes through above-mentioned astigmatism cover as a result,
1 setting, the reflection and refraction of rib body 2 of the light that LED light issues through wavy concaveconvex structure, makes light in astigmatism cover
Reach equally distributed effect on 1, reduces the light efficiency gap of intermediate region and fringe region, and then it is dizzy to efficiently solve lamps and lanterns
Optical issue, while farthest ensure that the illuminating effect of lamps and lanterns.
Illustratively, the preferably circular cover of the astigmatism cover 1.The center of the astigmatism cover 1 is located in LED light
On heart optical axis.Such setting, can enable LED light generate light uniform irradiation to target area on, make the light of lamps and lanterns
According to region uniform and can be bigger according to amount.
Illustratively, to guarantee that astigmatism cover 1 uniformly goes out the effect of light, two adjacent rib bodies 2 are formed by folder
Angle is gradually increased in the range of 0 degree to 90 degree from the center of astigmatism cover 1 around.
Illustratively, it is screwed between the astigmatism cover 1 and lamp holder.In the present embodiment, the astigmatism cover 1
Cover mouth be equipped with several mounting holes 3 passed through for screw.
Above disclosed is only the preferred embodiment of the utility model, certainly cannot be practical new to limit this with this
The interest field of type, therefore equivalent variations made according to the patent scope of the utility model still belong to the utility model and are covered
Range.
