Abstract

The invention provides a laser flashlight. The laser flashlight comprises a flashlight body, a power source, a lighting module and a control switch. The power source is arranged on the inside of the flashlight body. The lighting module is arranged at the front end of the flashlight body. The control switch is mounted on the flashlight body in an embedded mode. The power source is connected with the lighting module and the control switch correspondingly. The lighting module includes an optical device and an optical device barcket. The optical device is fixed to the inside of the optical device bracket. The optical device includes a laser light source, a collimator lens, a focusing lens, a fluorescent powder film and a reflection cup arranged on the optical device bracket in sequence from bottom to top. The laser light source is installed in the center of the bottom of the optical device bracket. A light transmission cover is arranged on the top of the optical device bracket. The top of the reflection cup is closely connected with the light transmission cover. The laser flashlight is simple in structure, the light energy loss is greatly reduced, and the utilization rate of light energy is improved; the laser flashlight has the advantages of good in directivity, far in irradiation distance and the like; and the actual lighting demand can be satisfied well.

Description

Technical field [0001] The invention belongs to the technical field of lighting appliances, and specifically relates to a laser flashlight. Background technique [0002] As a special kind of light source, laser is widely used in military, aerospace, civil and other fields. As a laser light source, the fluorescent component that excites fluorescent powder and the resulting fluorescence is used as illuminating light. The flashlight has become a must-have for household life, and the use of laser as the light source of the flashlight has gradually been widely used. [0003] Generally, the laser light generated by the laser light source is strip-shaped, and the semiconductor laser irradiates the object as a strip-shaped non-uniform spot, which cannot be used to uniformly illuminate an object of a specific area. Summary of the invention [0004] The present invention aims to solve the above technical problems and provide a laser flashlight with high utilization rate of light energy and g...
