Abstract
The utility model discloses a television backlight lens which comprises a light-exiting surface located at the surface of the lens, a light-entering surface located at the bottom surface of the lens, and a mesh surface located on the bottom surface of the lens and surrounding the periphery of the light-entering surface. The light-exiting surface and the light-entering surface are diamond turning mirror surfaces. The luminous flux and the light transmittance of the lens are improved greatly, and uniformity of light is high. Mesh points of the mesh surface are cone-shaped bodies, so the divergence effect of the light is good.
Description
Technical field
The utility model relates to a kind of lens, refers specifically to a kind of television set lens backlight.
Background technology
The optical surface of conventional television lens backlight all adopts burnishing surface, and burnishing surface is to adopt polishing it is comparatively coarse, usually causes the luminous flux of lens, light transmittance to reduce greatly, and the uniformity of light is poor.Circle is all adopted in its site of wire side of conventional television lens backlight bottom, can cause the weak effect of dispersing of light.
The utility model content
The technical problems to be solved in the utility model provide a kind of light uniformity height, disperse effective television set lens backlight.
In order to solve the problems of the technologies described above, the utility model is realized by following technical scheme.
A kind of television set lens backlight comprise an exiting surface that is positioned at lens surface, an incidence surface that is positioned at the lens bottom surface, and a wire side that is positioned at the lens bottom surface and centers on the incidence surface periphery, it is characterized in that: described exiting surface is the diamond turning minute surface.
Described incidence surface is the diamond turning minute surface.
The site of described wire side is bullet.
The utility model beneficial effect is that exiting surface, incidence surface are the diamond turning minute surface, and luminous flux, the light transmittance of lens improve greatly, the uniformity height of light.The site of wire side is bullet, and dispersing of light is effective.
