Problems solved by technology

However, the body of this ordinary milky diffuser plate is composed of uniform and random diffused particles. No matter what direction the incident light passes through, it will form a cosine-Lambert-shaped luminous intensity distribution, which will cause certain glare light pollution, which cannot meet the requirements of architectural design.

Abstract

The invention belongs to the technical field of illumination and provides an optical structural plate. The optical structural plate comprises a tabulate transparent body and a plurality of convex condensation units which are evenly arrayed on at least one surface of the body. The surface of each convex condensation unit is of a mirror structure. The body and the convex condensation units are integrally formed. The multiple convex condensation units are arrayed in a plurality of lines. The convex condensation units in every two adjacent lines are distributed in a staggered mode, so that the convex condensation units are integrally in a honeycomb shape. According to the optical structural plate, the multiple convex condensation units are formed on the surface of the body and are integrally in the honeycomb shape, so that large-angle light which enters the convex condensation units and deviates from the center axes of the convex condensation units is emitted out at a small angle after being refracted and totally reflected by the surfaces of the convex condensation units, glare caused by leakage of the large-angle light is prevented, and light pollution is avoided; moreover, the closely-distributed convex condensation units also have a light homogenizing effect; in addition, the optical structural plate is not doped with diffusion particles, so that the light transmittance is remarkably improved; and meanwhile the light receiving effect and light homogenizing effect of the optical structural plate are improved.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to an optical structure board and an LED lighting device. Background technique [0002] As a new type of environmentally friendly light source, LED is widely used in TV backlight, general outdoor lighting, general indoor lighting, automotive lighting and other fields. At present, in LED indoor lighting fixtures, surface luminous panel lamps mostly use plates added with milky white diffuser, referred to as diffuser plates, whose main function is to cover the LED and light guide plate outlets, so that they will not be particularly dazzling when used. However, the body of this ordinary milky white diffuser plate is composed of uniform and random diffused particles. No matter what direction the incident light passes through, it will form a cosine-Lambert-like luminous intensity distribution, which will cause certain glare light pollution, which cannot meet the requirements ...
