The led light source exiting surface is that its characteristics of luminescence of a plane is a lambertian distribution in addition, if directly use or continue to use the luminous intensity distribution way of conventional light source without suitable optical system processing, mostly is difficult to satisfy the required performance indications that reach of lighting.Like traditional Planar Quadratic optical texture, even if processing such as surface micro-structure are arranged, can only be among a small circle the light field spatial distribution of change system.

Compared to conventional light source; Characteristics such as led light source has efficiently, safety, energy-saving and environmental protection, long-life, response speed are fast, colour rendering index height; Especially it is smaller and more exquisite that the characteristics aspect volume make the LED light fixture; But thing followed glare problem faces certain test for the LED light fixture, and the method for conventional process dazzle is hidden light source, adds means such as anti-dazzle circle and grid deeply; But these all are to be cost to reduce Luminaire efficiency without exception, not only have been unfavorable for energy-conservation consideration but also can better brought into play the characteristics of led light source.

The utility model content

The utility model technical problem to be solved is; Overcome the problem that exists in the prior art; A kind of new LED non-planar optics face shield is provided; It is to led light source, and the spatial light field that can better improve led light source distributes, and can effectively reduce dazzle numerical value for the LED light fixture and promote lighting quality.

For the technical scheme that addresses the above problem the utility model is such:

A kind of new LED non-planar optics face shield; Said optics face shield is made up of the anti-glare optical unit structure of the identical or different non-planar mixed light of one or more structures; The optical unit structure is semi-enclosed housing, and the opening portion of housing is corresponding to the mounting hole site of LED lamp.

The optical unit structure rotary body that one or more snippets bus forms after rotating of serving as reasons, bus are that one or more of straight line, circular arc, parabola, free curve connect combination.

The optics face shield is processed by the diffusion material of printing opacity, and handle through atomizing on optics face shield surface.

Through this optical unit structure, the optical field distribution of led light source is effectively reduced its peak brightness by spatial expansion.

In the process of the combination of many moneys optical unit structure, to the height of each optical unit structure and the adjusting of position, and the cooperation of adjacent optical unit structure; The peak brightness of led light source is inhibited again; The LED light fixture that cooperates the optical texture of this non-planar is being guaranteed on the basis of Luminaire efficiency, reaches system's optical field distribution of expection; Reduce the dazzle index of LED light fixture, promoted lighting quality.
