Technical Field

Background

In life, the uniformity and collimation of the surface light source can directly influence the application effect and application range of the product. In the fields of exposure machines, 3D surface forming photocuring, projection application and the like, the requirements on the uniformity and the collimation of a light source are high. The light emitted by the existing light sources such as LED lamps is scattered and cannot form parallel light, so that the light generated by the existing light sources needs to be converged by the lamp to form the parallel light, and the uniformity and the collimation of the light meet the requirements.

However, in the conventional lens-type LED array light source, because the lens and the lens (lamp and lamp) inevitably generate a patchwork spot in the splicing process, there are problems such as insufficient uniformity of light; in the lumen-imitating LED array light source, the collimation of the light source is insufficient, so that the application of the LED array light source is limited. In addition, the two types of LED array light sources are implemented based on two-layer optics, i.e., a primary optical component (primary optics) is soil-encapsulated by an LED chip, and then a lens (secondary optics) is added, thereby resulting in higher manufacturing cost.

Therefore, it is desirable to design an optical member to solve the above problems.
