Light guide plate manufactured by inner carving, manufacture method thereof and lighting lamp

Abstract

The invention discloses a light guide plate manufactured by inner carving, aiming to provide a light guide plate which is characterized in that the light guide spot of the light guide plate does not become yellow because of air oxidation and dust pollution, and the light guide plate improves light guide efficiency, reduces luminous decay and prolongs the service life the light guide plate. The light guide plate is provided with the light guide spot comprising an inner light guide spot manufactured in the light guide plate by inner carving via laser. The invention also provides a manufacture method of the light guide plate and the lighting lamp with the light guide plate. The invention can be used for various fields of lighting, artistic lighting, decorative lighting, bathtubs, artware, artworks, furniture lighting, decorative materials, shopwindows, cabinets, display stands, direction boards and the like.

Description

technical field [0001] The present invention relates to a light guide plate, in particular to a light guide plate and a manufacturing method thereof which are suitable for various types of lighting, artistic lighting and decorative lighting, decorative materials, showcases, cabinets, display stands, etc. Lighting fixtures with light panels. Background technique [0002] In the field of liquid crystal display manufacturing, the light guide plate is used to pass the light emitted by fluorescent lamps, CCFL, LED and other light sources through the light guide point or light guide groove designed according to the optical principle. Under the action of the reflective film (reflector) and the diffusion film, Converts a directional or point light to an area light. In order for the light guide plate to emit light evenly, it must pass through various light guide points of different densities and sizes to ensure that the efficiency of light reflection in all directions is basically t...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the technical problems that the light guide point of the light guide plate in the prior art is exposed and easily oxidized by air and dust pollution and cause yellowing, resulting in a decrease in light guide efficiency, a large light attenuation, and a decrease in service life, the present invention provides an internal light guide plate. Light guide plate made by engraving, its manufacturing method, and lighting fixture with the light guide plate
