Abstract

The invention relates to the field of illumination devices, in particular to a laser projection lamp. By adoption of the laser projection lamp, the problems that existing projection lamps are low in energy conversion rate, short in irradiation distance, short in service life and the like are solved. The laser projection lamp comprises a housing, a lamp shade, a mounting support and a light-emitting assembly. The light-emitting assembly is located in a cavity defined by the shell and the lamp shade and comprises a heat dissipation substrate, a laser control module and a laser module, wherein the laser module is fixedly arranged on the front side of the heat dissipation substrate, a radiator is arranged on the back side of the heat dissipation substrate, and the laser control module is connected with the laser module. The laser module comprises a laser module shell, a lens pressing ring, a lens, a yellow phosphorus filter and a laser emission device, wherein the lens pressing ring, the lens, the yellow phosphorus filter and the laser emission device are sequentially arranged inside the laser module shell, and the lens pressing ring tightly presses the lens and the yellow phosphorus filter in the axial direction. According to the laser projection lamp, laser light is used as an illumination light source, the energy conversion rate is increased, and the irradiation distance of theillumination device is increased.

Description

technical field [0001] The invention relates to the field of lighting devices, in particular to a laser projection lamp. Background technique [0002] With the development of society, projection lamps are used in more and more occasions, and projection lamps are generally used for lighting and decoration. Most of the existing projection lamps use LED light-emitting diodes as lighting sources. LED lighting sources have the advantages of long life, energy saving, environmental protection, rich colors, and miniaturization. However, LED light-emitting diodes convert a large part of the input electric energy into heat energy. The energy efficiency conversion rate is low, resulting in serious energy waste; at the same time, LED light-emitting diodes have a small area and high heat density, and poor heat dissipation leads to an increase in junction temperature, which seriously affects the luminous wavelength, luminous intensity, luminous efficiency and service life. In addition, L...
