Abstract
The utility model provides a LED lens face lid, including the front and the back, for going out the plain noodles, glossy plane openly, the back is equipped with fixed column and lens, the solid of revolution of lens for being the round platform form, the sunken light source for cavity that forms in lens bottom, the lens lateral wall forms the complete reflective surface. The utility model provides a LED lens face lid, not only processing technology is simple, easily realizes having efficient spotlight function in addition, and light that LED sent is through the secondary optics effect back of lens face lid, and luminous angle is very little, when guaranteeing the spotlight function, has greatly improved the efficiency of light energy utilization of lamps and lanterns, improvement light efficiency. Going out the plain noodles and be the plane, be favorable to lens to be surface treatment, surface treatment technology is simpler than non - planar lens, more evenly, the effect is better.
Description
Technical field
This utility model belongs to technical field of semiconductor illumination, is specifically related to a kind of LED lens cover.
Background technology
LED as a kind of novel lighting system, have life-span length, consume energy low, volume is little, high brightness, controls the advantages such as flexible, belongs to typical green illumination light source, its application prospect is more and more extensive.
LED light source distribution curve flux approximate Lambertian type, directly can not reach during application to design needs, it is necessary to carry out secondary light-distribution design.The secondary light-distribution basic optical element that used of design mainly has lens, but the traditional optical lens such as cylindrical mirror or the coquille etc. that are used mostly, their exiting surface typically uses a smooth flat or smooth surface, and relatively greatly, illumination range is wider for rising angle.And major part place needs illumination range little but light is concentrated, the high illumination spot of brightness in actual illumination.In these cases, if directly using conventional lenses, then it is likely to result in a part of light and can be irradiated to cause outside required illumination region the waste even light pollution of luminous energy, a lot of light cannot utilize, cause the problem that LED light flux utilization is low, eventually reduce light fixture light efficiency, also make required illumination district intraoral illumination intensity substantially inadequate simultaneously, affect radiation response.Therefore, it is necessary to LED lens are carried out optically focused design.But, LED collecting lens of the prior art, structure is complicated, difficulty of processing compared with big, realize cost is high, spotlight effect is undesirable defect and deficiency, limit it and promote the use of.
Summary of the invention
To be solved in the utility model is the technical problem that existing LED lens difficulty of processing is big, spotlight effect is undesirable, it is provided that the LED lens cover that a kind of simple in construction, spotlight effect are good, the efficiency of light energy utilization is high.
In order to solve technical problem of the present utility model, this utility model is achieved through the following technical solutions: LED lens cover, and including front and back, described front is exiting surface, is smooth plane；The described back side is provided with fixing post and lens, and described lens are in round table-like revolving body, and described lens bottom notch forms light source and accommodates chamber, and described lens sidewall forms fully reflecting surface.
Preferably, the height height 0.7mm ~ 1.1mm of the aspect ratio lens of described fixing post, facilitate the installation of LED lens cover.
Preferably, described LED lens cover front is other suitable shapes of meeting circular, oval, square, according to light fixture shape or customer requirement, can select flexibly.
Preferably, described LED lens cover uses PC material to make, and light transmission is good, and intensity and reliability are high, and salt spray resistance, anticorrosive.
Preferably, described lens numbers is at least 1, can carry out lens numbers regulation according to lamp power requirement.
Compared with prior art, this utility model obtains and provides the benefit that:
A kind of LED lens cover disclosed in this utility model, not only processing technique is simple, it is easily achieved, and there is efficient light-focusing function, the light that LED sends is after the secondary optics effect of lens cover, and light emitting anger is the least, while ensureing light-focusing function, greatly improve the efficiency of light energy utilization of light fixture, improve light efficiency.
LED lens cover disclosed in this utility model, exiting surface be plane, beneficially lens do surface process, process of surface treatment is simpler than non-planar lens, evenly, effect more preferable；Exiting surface is the convenience that plane substantially increases that light fixture is safeguarded, after lens surface laying dust, can be easy to cleaning, there is not cleaning dead angle, so that light fixture maintains higher maintenance factor, keeps good optical property；LED lens cover uses PC material to make, and light transmission is good, and intensity and reliability are high, and salt spray resistance, anticorrosive.
Accompanying drawing explanation
Fig. 1 is this utility model structure chart.
Reference: 1, exiting surface；2, lens；21, light source accommodates chamber；3, fixing post.
Detailed description of the invention
Below in conjunction with the accompanying drawings, embodiment is described in detail.
Seeing accompanying drawing 1, LED lens cover, including front and back, described front is exiting surface, is smooth plane；The described back side is provided with fixing post and lens, and described lens are in round table-like revolving body, and described lens bottom notch forms light source and accommodates chamber, and described lens sidewall forms fully reflecting surface.
Further, the height height 0.7mm ~ 1.1mm of the aspect ratio lens of described fixing post, facilitate the installation of LED lens cover.
Further, described LED lens cover front is other suitable shapes of meeting circular, oval, square, according to light fixture shape or customer requirement, can select flexibly.
Further, described LED lens cover uses PC material to make, and light transmission is good, and intensity and reliability are high, and salt spray resistance, anticorrosive.
Further, described lens numbers is 6, can carry out lens numbers regulation according to lamp power requirement.
Listed above is only one of specific embodiment of the utility model.Obviously, this utility model is not limited to above example, it is also possible to have many similar reshapings.All deformation that those of ordinary skill in the art can directly derive from this utility model disclosure or associate, are all considered as this utility model scope of the claimed.
