Side-light type light-emitting module

Abstract

The invention relates to a side-light type light-emitting module which comprises a light guide plate, a first light-emitting unit and reflecting pieces. After penetrating at least the first reflecting piece, light emitted by the first light-emitting unit is uniformly guided to the light-exiting face of the light guide plate, and the side-light type light-emitting module can be provided with one or more light-exiting faces through the design of multiple dots additionally arranged on the light guide plate and the second reflecting piece.

Description

technical field [0001] The invention relates to a side-light light emitting module, in particular to a side light light-emitting module using secondary optics. Background technique [0002] Generally speaking, the light-emitting diode (LED, Light-Emitting-Diode) light emitting method includes point light source and surface light source. The point light source is a light source idealized as a particle that emits light in all directions, and the surface light source consists of the entire surface of the light-emitting area. Gives even light. Compared with the LED point light source, the LED surface light source is a flood light, so the light angle is larger, and it is less likely to produce black shadows or double shadows. There is no glare, and the light is uniform and soft without hurting the eyes. Although there is also a way to make the overall light soft and uniform through the design of the lampshade in the point light source, but through this method, part of the light ...

Problems solved by technology

[0006] By setting a plurality of LED strip light sources, although the problem of optical dark areas can be solved, another problem will be derived, that is, when the number of light sources is too small, the gap between the light sources will be reduced. If the gap between multiple light sources is too large, the obvious problem of the optical dark area cannot be perfectly solved. However, if the light distribution is uniform and the optical dark area is not obvious, it is necessary to make the gap between multiple light sources The shortening of the gap produces a large number of light-emitting diodes in the strip light source, resulting in a large amount of cost and power loss

[0007] The reason is that the traditional side-light light-emitting module needs to be equipped with more light-emitting diodes to solve the problem of optical dark areas. In view of this, the inventor designed a way to use reflection to provide a uniform surface light source with a small number of light sources. , which is assisted by many years of manufacturing and design experience and knowledge in related fields, and a newer research and development improvement for the existing edge-lit light-emitting module, in order to exert its higher practical benefits
