Problems solved by technology

At present, this kind of application mainly adopts the method of combining multiple planar LED surface light sources to realize the multi-angle light emission of LED surface light sources. However, due to the influence of the view angle of the observer, this application mode cannot achieve a better light source transition. Feedback to In the eyes of the observer, the bend is an intermittent image, which cannot meet the user's needs for curved surface light sources

Abstract

An LED arc area light source comprises an LED light bar, a radiating support, and a light guide plate. The light guide plate is in an arc bent structure and comprises a flat portion and an arc bend. The bent inner side of the arc bent structure is the inner side of the light guide plate. The bent outer side of the arc bent structure is the outer side of the light guide plate. The light guide plate comprises a light source input end. The LED light bar is mounted at the tail end of the arc bent structure of the light guide plate. The end, which the LED light bar is mounted at, is an incident end of the light guide plate. The radiating support is disposed at the incident end of the light source and in lap joint with the LED light bar. The radiating support functions in fixing and supporting the whole arc area light source. The arrangement density of light guide points of the bent portion of the light guide plate is smaller than that of the flat portion of the light guide plate. The LED arc area light source with variable shape has the advantages of variable shape and lighting uniformity, is capable of emitting light, and is applicable to more places.

Description

technical field [0001] The invention belongs to the technical field of light sensing and relates to an LED surface light source, in particular to an LED arc-shaped surface light source. Background technique [0002] LED surface light source is a kind of LED light source, which has the characteristics of long life and small size. Compared with LED point light source and traditional lamps, it is a new lighting mode. [0003] Traditional LED surface light sources are flat surface light emitting structures, but LED surface light sources are used in a wide range of occasions, and are usually applied to curved surfaces, corners, etc., and sometimes the number of bending times of folded surfaces and corners is more than one. At present, this kind of application mainly adopts the method of combining multiple planar LED surface light sources to realize the multi-angle light emission of LED surface light sources. However, due to the influence of the view angle of the observer, this ap...
