Optical element and lamp

Abstract

The invention discloses an optical element and a lamp, and relates to the field of illumination. The optical element comprises at least two lens units, the bottom of each lens unit is provided with a containing cavity, and the containing cavities are used for containing light-emitting parts. The lens units are used for generating asymmetric light beams from light emitted by the light-emitting parts; and the asymmetric light beams emitted by the plurality of lens units are combined to obtain an emergent light beam in a preset irradiation range. The lamp illuminates through the optical element. Through the arrangement of the plurality of lens units, a plurality of asymmetric light beams can be generated, and at the moment, the polarization angle of the emergent light beam of each lens unit is adjusted, so that the asymmetric light beams with different polarization angles can be obtained. Therefore, the range of the area needing to be irradiated can be divided into the multiple sub-irradiation areas so that each asymmetric light beam can be deflected into the corresponding sub-irradiation area, and compared with a traditional illumination mode, due to the fact that the light rays are more fully and effectively utilized, the effective utilization rate of light of the light-emitting parts in the lamp can be increased.

Description

technical field [0001] The present application relates to the lighting field, in particular to an optical element and a lamp. Background technique [0002] In the field of lighting, such as the fishing industry, it is necessary to irradiate enough light in the fishing area to attract fish to gather; in other industries, such as the stage, it is also necessary to cover the entire site with light. Therefore, in order to achieve this specified range of light intensity, high-power lamps are usually used for irradiation to meet the light requirements at a distance. Taking the fishing industry as an example, high-power metal halide lamps and some LED fishing lights are used for irradiation; however, this metal halide lamp emits light at 360 degrees, and the effective utilization rate of light is low. Some LED fishing lights on the market use street lamp lenses for light distribution, but the light near the boat and near the bottom is less. After adjusting the light through the ro...

Taking the fishing industry as an example, high-power metal halide lamps and some LED fishing lights are used for irradiation; however, this metal halide lamp emits light at 360 degrees, and the effective utilization rate of light is low

Some LED fishing lights on the market use street lamp lenses for light distribution, but the light near the boat and near the bottom is less. After adjusting the light through the rotation angle, although the light near the boat and near the bottom is improved, it also sacrifices part of the boat. Some LED fishing lights use transparent covers to distribute light, and the angle is small. The range of exposure on sea level is not wide, and LED light cannot be fully utilized within the expected range of exposure, resulting in low light utilization.
