Abstract
The utility model discloses a kind of LED light lens, comprise LED lens body, be provided with LED installation cavity in this LED lens body, the exiting surface of described LED lens body is coated with magnesium fluoride rete, and this magnesium fluoride rete is coated in outer surface or the inner surface of LED lens body exiting surface.The utility model, by arranging magnesium fluoride rete at the light output surface of lens, can reduce the reflection of camera lens interface to incident light line, reduces halation, strengthens LED light effect, improves the utilization rate of light.
Description
Technical field
the utility model relates to LED light source technical field, specifically a kind of LED light lens.
Background technology
LED light source is widely used in lighting field, in use because the field used or purposes difference, will carry out an optics or secondary optical design in the design process, employ optical lens and optical material in large quantities.When refraction and reflection can occur LED light line light when an interface (plane or the curved surface) of optical lens, and angle also can change when adjusting the distance between lens and LED, lens flare through optical design will be very even, but due to the restriction of lens material and Lens-Mode, there is some light can reflect in optical lens, cause the light utilization efficiency of LED not high.In order to improve the penetrance of light, part LED, by improving on fitting structure, owing to improving the structure of light fixture itself, usually can relate to comparatively complicated technique, and improve manufacture difficulty.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of LED light lens, and reduce camera lens interface to the reflection of incident light line, light utilization efficiency is high.
A kind of LED light lens, comprise LED lens body, be provided with LED installation cavity in this LED lens body, the exiting surface of described LED lens body is coated with magnesium fluoride rete.
Described magnesium fluoride rete is coated in the outer surface of LED lens body exiting surface.
Described magnesium fluoride rete is coated in the inner surface of LED lens body exiting surface.
Described magnesium fluoride rete is coated in outer surface and the inner surface of LED lens body exiting surface.
Described magnesium fluoride rete at least arranges one deck.
Described LED lens body utilizes PMMA, optics PC material, clear glass or silica gel to make.
The utility model applies magnesium fluoride rete by the optical interface that goes out at LED lens, can reduce the reflection of camera lens interface to incident light line, reduce halation, strengthens LED light effect, improves the utilization rate of light, make luminescence more even.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model cross-sectional view;
Accompanying drawing 2 is the decomposing state structural representation of 1.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in figure 1 and 2, the utility model discloses a kind of LED light lens, comprises LED lens body 2, is provided with LED installation cavity 3 in this LED lens body 2, the exiting surface of described LED lens body 3 is coated with in magnesium fluoride rete 1, LED installation cavity for mounted LED lamp.When specific design, can only at the outer surface magnesium fluoride rete of the exiting surface of LED lens body, also can only at the inner surface coating magnesium fluoride rete of the exiting surface of LED lens body, or apply magnesium fluoride rete at the inner surface of the exiting surface of LED lens body and outer surface simultaneously.LED lens body utilizes the materials such as PMMA, optics PC material, clear glass or silica gel to make.By arranging magnesium fluoride rete, to reduce the reflection of lens interface to incident light line, reducing halation, strengthening LED light extraction efficiency.
According to different LED lens, according to film interference principle, utilize the coating process such as sputtering method or thermal resistance vaporation-type, go out at LED lens the magnesium fluoride plated film that optical interface carries out single or multiple lift.
It should be noted that, the LED lens in the utility model can be designed to various shape.The above embodiment only have expressed the specific embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that the technology for this area, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Claims (4)
