Laser lighting lamp

Abstract

The invention discloses a laser lighting lamp comprising a light emitting unit, a mounting unit for fixing the light emitting unit and a heat radiating unit respectively connected with the light emitting unit and the mounting unit; the light emitting unit comprises a laser source fixedly arranged on the mounting unit; the heat radiating unit comprises a heat radiating shell sleeving the periphery of the mounting unit and a heat conducting part located between the laser source and the heat radiating shell; an emergent beam of the light emitting unit is emergent along the axis direction of the heat radiating shell; the heat conducting part is a metal sheet which is of a rectangular structure; and the inner side of the heat radiating shell is provided with a connecting piece fitted with one of surfaces of the heat conducting part. The laser source is used as a lighting source, so that the lighting distance is prolonged, and the lighting brightness is improved; and the heat radiating shell and the heat conducting part are arranged, the heat conducting part is the metal sheet which is of the rectangular structure, and the heat radiating shell is provided with the connecting piece fitted with the heat conducting part, so that heat generated by the laser source is rapidly guided out of the heat radiating shell and is rapidly radiated, and the problems that the local temperature is overhigh, and even, the laser source is burnt out are avoided.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a laser lighting lamp. Background technique [0002] With the development of semiconductor technology, LED (Light Emitting Diode, light-emitting diode) light source has the advantages of high efficiency, energy saving, environmental protection, low cost and long life, and is gradually replacing traditional incandescent lamps and energy-saving lamps, becoming a general lighting Light source, due to the limitation of the brightness of the current LED light source, there is usually the problem that the central illumination is obviously not enough. In applications such as marine searchlights, stage lighting, car headlights, projection displays, etc. that require ultra-high brightness and long-distance lighting, LED The light source is difficult to meet the requirements. [0003] The laser light source has the advantages of concentrated energy and long irradiation distance, and can ...

AI Technical Summary

Problems solved by technology

However, due to the high heat generation of the laser light source, the heat dissipation requirements are very high. Once the heat dissipation is insufficient, it is easy to cause local overheating, affecting normal use or even burning out the laser light source and other components.
