Optical lens and aviation obstruction light using the optical lens

Abstract

The invention provides an optical lens, which is used for reflecting light emitted by a light source inside the optical lens. The optical lens is shield-shaped; a cavity is formed inside the optical lens; the optical lens comprises a bottom surface, an light incidence surface arranged on the inner side and a plurality of light emergence surfaces and a plurality of outer light split surfaces which are arranged on the outside; lens light refraction areas are formed between the light emergence surfaces and the light incidence surface; light is sent from the inside of the optical lens, and is reflected to the outside of the optical lens by the lens light refraction areas; and the light emergence direction deflects toward the bottom surface of the optical lens relative to the light incidence direction. The invention further provides an aviation obstruction beacon.

Description

technical field [0001] The invention relates to an optical lens and an aviation obstruction light using the optical lens. Background technique [0002] Aviation obstruction lights are an important facility for aircraft navigation. The optical lenses used in existing aviation obstruction lights are usually Fresnel lenses, but Fresnel lenses are only suitable for spherical illuminants such as incandescent lamps, not Diode light source suitable for directional light emission. And because existing aviation obstruction light adopts incandescent lamp as luminescent light source, so its power is big, energy consumption is high, life-span is short, is unfavorable for maintenance and long-term use. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned prior art, the present invention provides an optical lens and an aviation obstruction light using the optical lens. [0004] An optical lens for refracting light emitted by a light source d...

[0002] Aviation obstruction lights are an important facility for aircraft navigation. The optical lenses used in existing aviation obstruction lights are usually Fresnel lenses, but Fresnel lenses are only suitable for spherical illuminants such as incandescent lamps, not Diode Light Sources for Directional Lighting

And because the existing aviation obstruction lights use incandescent lamps as light sources, they have high power, high energy consumption, short life, and are not conducive to maintenance and long-term use.
