Problems solved by technology
[0007] If this convex lens grating is used for light distribution, there will be at least the following two disadvantages: one is that all the light is concentrated directly below, and in the case of a short lighting distance, the effect of wide lighting area cannot be achieved; the other is that all the light overlaps High performance, easy to produce Gaussian distribution phenomenon, unable to achieve uniform distribution of light
[0008] Therefore, the light-transmitting lampshade 104 in the lamp cannot use the currently known grating plate to improve the problem and achieve the light distribution effect

Embodiment Construction
[0066] The invention relates to a light distribution plate with a plurality of complex focus gratings. One or more light-transmitting plates are used to shape the light distribution plate as a lighting mask body of a lamp. The shape of the light-transmitting plate can be square, circular, oval, and special-shaped; the material of the light-transmitting plate can be light-transmitting plastic, light-transmitting glass or other light-transmitting materials. At least one side of the light-transmitting plate is formed with a plurality of strip-shaped, ring-shaped, cloud-shaped linear or granular compound focus gratings, each of which is composed of two or more than two curved lenses, with two or more The compound focal point single grating with more than two focal points, and the curvature and inclination of each curved lens forming the complex focal point single grating are designed according to the angle at which the incident light is to be refracted by the surface of the curved ...

A light distribution board having a plurality of light gratings each with multiple focuses, the light distribution board is used on a light outputting surface of a lamp, in which at least a transparent board is provided on at least one of its surfaces with a plurality of light gratings each having multiple focuses, each light grating having multiple focuses is composed of two or more mutually integratedly juxtaposed arciform (concave or convex) lenses to form a convex lens grating having two or more focuses. With this structure, light beams can be uniformly distributed and can avoid the phenomenon of Gauss distribution that makes the area below the lamp especially bright, and can avoid the phenomenon of dazzling of eyes during looking at the light emitting member in the lamp; and except the light beams directly under the lamp, other light beams around the lamp are completely obscured, thus an effect of no optical pollution can be obtained.
Description
technical field [0001] The present invention relates to a light distribution plate with a plurality of complex focus gratings, which is designed by using the principles of optical reflection and refraction to be applied to various lighting lamps, so that the brightness of the lighting area of various lamps is uniform and the light is bright under the condition of minimum brightness loss. Soft, non-glare, suitable for home, office, factory and road lighting places to save energy and avoid light pollution. Background technique [0002] Lighting lamps are generally divided into two types for indoor and outdoor use, and indoor lamps are mainly half-covered (please refer to Figure 1A ), a semi-shield-type opaque cover body 101 is mainly installed above the light source 102, and a reflector 103 inside the cover body has a reflective effect. In addition to the light directly irradiated by the light source, the illumination light also has a lot of light from the reflector. 103 re...
