Annular light source device

Abstract

The invention discloses an annular light source device. The brightness of the light source device is improved. The annular light source device comprises a housing, a plurality of light sources, a plurality of collimating lenses and a converging lens. The plurality of light sources are arranged in the housing and are arranged along a circular trajectory. The plurality of collimating lenses are arranged in the housing, and one collimating lens and one light source are oppositely arranged. The converging lens is arranged on the housing, the collimating lenses are located between the converging lens and the light sources, and the converging lens extends along the circular trajectory. The collimating lenses are used for correcting light emitted from the light sources and emitting the light. Theconverging lens is used for converging the light emitted from the collimating lenses onto a target focus. The plurality of light sources arranged along the circular trajectory emit the light, and thelight is emitted into the collimating lenses. Since the converging lens also extends along the circular trajectory, the light emitted from the collimating lenses can be converged onto the target focus. Therefore, the brightness on the target focus is relatively large, and the brightness of the annular light source device is integrally improved.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to a ring light source device. Background technique [0002] In the field of lighting equipment, for example, when performing industrial inspection lighting, the light sources used are light bulbs, LED lights, etc. The article is irradiated by the light source, so that the staff can perform certain technological operations. [0003] However, the existing lighting equipment often uses a light bulb or LED lamp, and the light is emitted from these light sources at multiple angles, thus resulting in insufficient light for irradiating objects and the like, and the brightness provided by the lighting equipment is relatively small. Contents of the invention [0004] The object of the present invention is to provide a ring light source device for improving the brightness of the light source device. [0005] For reaching this purpose, the present invention adopts following tec...
