Technical Field

The present invention relates to an optical lens assembly and a mold for manufacturing the same, and more particularly, to an optical lens assembly capable of reducing UGR value and a mold for manufacturing the same.

Background

With the widespread application of LED lighting fixtures, optical lenses (including TIR lenses/fresnel lenses) have gained widespread acceptance in the market as excellent optical elements. Conventional optical lenses on the market at present have a common problem that the glare is serious, the light comfort is not enough, the health is not affected to a certain extent, and the utilization rate of light is reduced due to the stray light. Therefore, it is an urgent need for those skilled in the art to develop an optical lens assembly and a mold for manufacturing the same that can reduce UGR value.

SUMMERY OF THE UTILITY MODEL

The utility model provides an optical lens assembly capable of reducing UGR value and a manufacturing mold thereof in order to solve the defects.

The above object of the present invention is achieved by the following technical means: an optical lens assembly capable of reducing UGR value comprises a lens body, wherein a reticular groove is formed in the top of a light outlet of the lens body, and a reticular optical light receiver matched with the reticular groove is installed in the reticular groove.

Furthermore, a spherical protrusion is arranged on the end face of the light outlet of the lens body.

Furthermore, the radian of the upper end surface of the optical light receiver is completely matched with that of the end surface of the light outlet of the lens body, and the surfaces of the optical light receiver and the lens body are flat.

Furthermore, the optical light receivers are in a hexagonal array shape, a circular array shape and a square array shape.

Further, the optical light receiver is made of a non-transparent material.

Preferably, the surface color of the optical light receiver is black.

The utility model is that the top of the light outlet of the optical lens obtained by rotating a plurality of sections of high-order free curves for 360 degrees is provided with a regular reticular groove, the groove is embedded with an optical light receiver with a corresponding shape, and the radian of the upper end of the reticular optical light receiver is consistent with that of the groove at the upper end of the lens and can be completely embedded.

The manufacturing mold of the optical lens component capable of reducing the UGR value comprises a first mold and a second mold, wherein the first mold is provided with a cavity in the shape of the lens body, and the second mold is provided with a cavity in the shape of the reticular optical light receiver.

Compared with the prior art, the utility model has the advantages that: the utility model can greatly reduce visual glare and UGR value of the optical lens, and can obtain more comfortable lighting effect. Has better integrity, does not occupy extra space, and more importantly, has higher light-emitting efficiency than the prior art (as shown in fig. 4) while achieving the anti-dazzle effect. The diameter of the whole light receiver can account for 20% -80% of the diameter of the optical lens.
