Abstract

The invention provides an optical lens structure, applicable to guiding light rays emitted by a light source to multiple directions. The optical lens structure comprises a substrate, a column body and an umbrella body, wherein the substrate is provided with a containing slot applicable to containing the light source, the column body is connected onto the substrate, the column body is provided with a central shaft and a first curved surface, wherein the first curved surface symmetrically surrounds the central shaft; the umbrella body is connected onto the column body, the umbrella body is provided with a second curved surface and a third curved surface which symmetrically surround the central shaft, and the second curved surface and the third curved surface are arranged at the top of the umbrella body and are adjacent.

Description

technical field [0001] The present invention relates to a lens structure, and in particular to a divergent light emitting lens structure. Background technique [0002] With the progress of semiconductor technology, the luminous brightness and luminous efficiency of light-emitting diodes (LEDs) continue to increase. Since light emitting diodes have the advantages of fast response, high reliability, low power consumption, small size, low pollution, low driving voltage and no mercury, the application of light emitting diodes has become more and more extensive. [0003] However, the light-emitting diode is a point light source, and its light source characteristics have high directivity, so it cannot be directly applied to flood lighting equipment. Therefore, how to solve the gap between the lighting characteristics of light-emitting diodes and the existing lighting requirements, so that they can be applied to flood lighting, is actually a problem that relevant personnel should ...
