Problems solved by technology

This kind of three-dimensional painting technology has a simple structure, but the three-dimensional effect is relatively general, which largely depends on the viewing angle of the observer. If the viewing angle is wrong, a better three-dimensional lighting effect cannot be obtained.
At present, there is no LED three-dimensional light source technology that combines LED surface light source and three-dimensional picture

Abstract

An LED stereoscopic area light source comprises an LED light bar, a radiating support, and a light guide plate. The LED stereoscopic area light source is characterized in that the light guide plate comprises an incident end and an emergent end, the LED light bar is disposed at the edge of the light guide plate, the end, which the LED light bar is arranged at, is the incident end of the light guide plate, the radiating support is disposed at the incident end of a light source and in lap joint with the LED light bar, one side of the light guide plate is provided with light guide points, the other side, opposite to the light guide points, of the light guide plate is an emergent side of the light guide plate, the emergent side of the light guide plate is provided with a stereoscopic pattern which is made on the light guide plate by carving, and the surface of the stereoscopic pattern is provided with a coating. The LED area light source capable of mapping stereoscopic diagrams is designed by combining the traditional area light source, the stereo technology and the nano technology; the LED area light source has the effect of stereoscopic lighting, is capable of emitting light and is also ornamental.

Description

technical field [0001] The invention belongs to the technical field of optical lighting and relates to an LED surface light source, in particular to an LED three-dimensional surface light source. Background technique [0002] Three-dimensional picture technology is a technology with high ornamental value. At present, most three-dimensional picture technology uses grating materials combined with corresponding patterns, and uses the refraction effect of grating to achieve three-dimensional visual effects. It can also be called grating three-dimensional picture technology. There is also a three-dimensional picture technology that combines the grating three-dimensional picture technology with optical technology, and the three-dimensional picture can realize the effect of light by setting a simple optical illuminant behind the grating three-dimensional picture. This three-dimensional painting technology has a simple structure, but the three-dimensional effect is more general, and...
