Abstract
The utility model provides scattered lens which has lower light emitting dissipation to a light source and is used for a LED light source light fitting. The scattered lens is formed by superposed a micro convex lens group and Fresnel lens, wherein, one end of the micro convex lens group adopts a light entering face, and one end of the Fresnel lens adopts a light emitting face. The utility model perform the scattering and the convergence to the LED light source emergent light through the micro convex lens group and the Fresnel lens, to reach the purpose of ensuring the LED light source emergent light to scatter and enlarge the partial light emitting quantity, and the utility model has lower light emitting dissipation to the light source.
Description
Technical field
The utility model relates to a kind of scattering eyeglass that is used for the led light source light fixture.
Background technology
LED is contained in the light fixture as light source, because the physical characteristic of LED is that the light emitting sheet area is little, luminous flux is big, so luminosity height of LED, when adopting many great power LEDs to make up to strengthen the bright dipping general power, it goes out light effect as shown in Figure 1, the emergent ray that converges has strong impulse to human eye, may produce strong dazzle and persistance of human vision to human eye when being used to throw light on, and influences vision.
Install the light source behind the scattering eyeglass additional, as shown in Figure 2, scattering has appearred in its emergent light, help eliminating glare effect, but general scattering eyeglass 1 is to form irregular pit at lens surface, or when being shaped, eyeglass adds the scattering particulate, make incident light produce unordered reflection and refraction, change optical transmission direction, thereby make the light after the outgoing produce dispersion effect, but because a part of light can be because of reflection and the excessive outgoing light source direction or repeatedly anti-that occurs turning back in refraction angle, the phenomenon that refraction back light energy weakens, therefore, the bright dipping loss of 1 pair of light source of this scattering eyeglass is relatively large, is unfavorable for effectively getting light.
The utility model content
Technical problem to be solved in the utility model provides a kind of scattering eyeglass of being used for led light source light fixture lower to the bright dipping loss of light source.
The technical scheme that the utility model technical solution problem is adopted: be used for the scattering eyeglass of led light source light fixture, described scattering eyeglass is formed by stacking by dimpling set of lenses and Fresnel mirror, and wherein, dimpling set of lenses one end is an incidence surface, and Fresnel mirror one end is an exiting surface.
The beneficial effects of the utility model: the utility model carries out scattering with the led light source emergent light by dimpling set of lenses and Fresnel mirror and converges, and reaches the purpose that makes the scattering of led light source emergent light and strengthen local amount of light, and lower to the bright dipping loss of light source.

The specific embodiment
As shown in Figure 3, scattering eyeglass of the present utility model is light transmission plastic cement or the glass scattering sheet that bimirror is formed by stacking, wherein, one side is a dimpling set of lenses 3, dimpling set of lenses 3 is that the dimpling lens of the end, dome are formed by the identical hexagon of a plurality of sizes, and the limit, limit, hexagon base of a plurality of dimpling lens joins, as shown in Figure 4; Another side is a Fresnel mirror 4 of carving concentric groove, and as shown in Figure 5, dimpling set of lenses 3 one ends are incidence surfaces, and Fresnel mirror 4 one ends are exiting surfaces, behind the incident light 2 process dimpling set of lenses 3 that led light source comes out, the Fresnel mirror 4, becomes emergent light 5.Scattering eyeglass of the present utility model go out light effect as shown in Figure 6.
The surperficial curvature of the dimpling lens by rational dimpling set of lenses 3; Reasonably led light source is to the distance of dimpling set of lenses 3, dimpling set of lenses 3 is distinguished imaging with led light source at exiting surface, as shown in Figure 7, enter the light of the LED imaging that the only part of human eye reduces through dimpling set of lenses 3 brightness of image, no longer be the high-luminance light that led light source produces, therefore played and reduced the spread effect of dazzle human eye.
The ring distance and the gradient of the cutting by rational Fresnel mirror 4, can improve the effect of its diffraction light, the characteristic that converges owing to 4 pairs of light of Fresnel mirror, therefore have certain light convergence effect, as shown in Figure 8, for the light fixture of only requiring local lighting, have raising illumination, reduce the effect of chromatic dispersion.
