Laser lighting lamp

Abstract

The invention discloses a laser lighting lamp. The laser lighting lamp comprises a light-emitting unit, an installation unit used for fixing the light-emitting unit and a cooling unit connected with the light-emitting unit and the installation unit. The light-emitting unit comprises laser sources. The light-emitting unit comprises a cooling shell and a heat conducting piece, wherein the cooling shell is arranged on the periphery of the installation unit and the heat conducting piece is located between the laser sources and the cooling shell. An outgoing beam of the light-emitting unit is emitted out in the axis of the cooling shell. The laser sources are located on the side face, perpendicular to the outgoing beam, of the installation unit. The heat conducting piece is of an L-shaped structure. The laser sources are used as a lighting source, so that the lighting distance and the lighting brightness are greatly improved. Because of the cooling shell arranged on the periphery of the installation unit in a sleeving manner and the L-shaped-structure heat conducting piece located between the laser sources and the cooling shell, heat generated by the laser source can be rapidly conducted outwards to the cooling shell by two edges and are rapidly dissipated, the situation that a local portion is overheated is avoided, and the stability and safety of the product are guaranteed.

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.
