Description

A kind of new LED non-planar optics face shield

Technical field

The present invention relates to a kind of new LED non-planar optical surface cover structure, its cooperated with LED light source uses, and has improved the spatial distribution of light field, has then effectively controlled surperficial dazzle for the LED light fixture.

Background technology

Flourish along with semiconductor lighting, the power of led light source, light efficiency continue to improve, and the size of led chip develops to miniaturization day by day, this has also caused the peak brightness of led light source to continue to strengthen, the peak brightness at high power white light LED (power is greater than 1W) light source place is basically all at 1,000,000 Cd/m2 in the market, when human eye is directly seen led light source, can produce discomfort, have the serious glare problem, can damage human eye when serious.

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.As 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, the method of conventional process dazzle, light source is hidden, is added 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.

Summary of the invention

Technical problem to be solved by this invention is, overcome problems of the prior art, a kind of new LED non-planar optics face shield is provided, it is at led light source, 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.

In order to address the above problem technical scheme of the present invention is such:

A kind of new LED non-planar optics face shield, described 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 made by the diffusion material of printing opacity, and handle through atomizing on optics face shield surface.

By 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.

The specific embodiment

For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.

Referring to Fig. 1 and Fig. 1 a, LED non-planar optics face shield is made up of the anti-glare optical unit structure of the identical or different non-planar mixed light of a plurality of structures, and 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 is a non-planar optical unit structure, has the dazzling function in mixed light side.The outer ring optical unit structure 2 of concrete face shield 1 is a dome shape, 3 on the inner ring optical unit structure of outer ring optical unit structure 2 is shorter dome shape, 8 optical unit structures 2 are closely arranged in the outer ring, inner ring is closely arranged 4 optical unit structures 3, the face shield the inside is then placed 8 the LED lamps 4 in outer ring accordingly, and inner ring is placed 4 LED lamps.

Optical unit structure

2 or 3 corresponding with positions such as LED.

The optics face shield is made by the diffusion material of printing opacity, and handle through atomizing on optics face shield surface.Can reach mixed light and anti-glare function preferably.

Referring to Fig. 2 a, first kind of optical unit textural association, optics face shield 1a is made of three optical unit structures, and these three optical unit structures are identical 2a, the compact middle part that is arranged in the optics face shield.

Referring to Fig. 2 b, second kind of optical unit textural association, optics face shield 1b is made of 11 optical unit structures, these 11 optical unit structures are arranged for being divided into two circles, the outer ring is optical unit structure 2b totally 7 annulus arrangements, inner ring optical unit structure 2b ' is four, the compact middle part that is arranged in the optics face shield.
