Problems solved by technology

[0002] At present, the lens used in LED spotlights is a single-focus plano-convex aspheric lens. When the light passes through this lens, the illuminance in the spot produced by this lens changes greatly, and light scattering is easy to occur around the spot, resulting in colorful color separation. The phenomenon is more serious, and it is easy to image, that is, the light spot is the shape of the light source
The above phenomenon has seriously affected the effect of stage lighting.

Abstract

The invention discloses a plano-convex composite aspherical lens of an LED (light-emitting diode) for a stage. The plano-convex composite aspherical lens comprises an aspherical convex lens layer, a first smooth-transition mirror layer and a large spherical convex lens layer, wherein the small end of the large spherical convex lens layer is connected with the large end of the first smooth-transition mirror layer into a whole; the small end of the first smooth-transition mirror layer is connected with the plane end of the aspherical convex lens layer into a whole; and the side wall of the large spherical convex lens layer, the side wall of the first smooth-transition mirror layer and the outer surface of the aspherical convex lens layer form a uniform arc surface. The plano-convex composite aspherical lens has the advantages that by arrangement of the aspherical convex lens layer, the first smooth-transition mirror layer and the large spherical convex lens layer, the light-spot imaging phenomenon can be avoided after the light spots are irradiated by a light source, and the multicolor separation phenomenon around the light spots is eliminated; and in addition, the uniformity of the light spots is good after the light spots are irradiated, the center luminance and the edge luminance of the light spots are decreased gradually without drastic change, and the effect of stage lighting is obviously improved.

Description

technical field [0001] The invention relates to a lens used in an LED spotlight, in particular to a plano-convex composite aspheric lens for an LED spotlight on a stage. technical background [0002] At present, the lens used in LED spotlights is a single-focus plano-convex aspheric lens. When the light passes through this lens, the illuminance in the spot produced by this lens changes greatly, and light scattering is easy to occur around the spot, resulting in colorful color separation. The phenomenon is more serious, and it is easy to image, that is, the light spot is the shape of the light source. The above phenomenon has seriously affected the effect of stage lighting. Contents of the invention [0003] The purpose of the present invention is to solve the above technical problems and provide a plano-convex composite aspheric lens for stage LED spotlights. The lens can overcome the spot imaging phenomenon, weaken the seven-color separation phenomenon around the spot, a...
