Abstract

The invention particularly relates to a focusing laser lighting device. The problems that an existing flashlight is small in irradiation area, not far enough in irradiation distance, low in energy efficiency conversion rate and unadjustable in luminance are mainly solved. The focusing laser lighting device comprises a barrel, a tail cover, a light-emitting assembly and a focusing assembly. The light-emitting assembly comprises a lens, a light transmitting mirror, a yellow phosphorus filter, a laser assembly and a circuit bin. The laser assembly comprises a laser support, a laser emitter and acircuit control board. The lens, the light transmitting mirror, the yellow phosphorus filter, the laser assembly and the circuit bin are arranged in the focusing assembly sequentially. The yellow phosphorus filter and the laser support are fixedly connected. The laser emitter is arranged in the laser support. The circuit control board is arranged in the circuit bin and is connected with the laseremitter. According to the focusing laser lighting device, the irradiation distance and area are increased, the luminous energy conversion rate is increased, the luminance is adjustable, and service life of a lamp is prolonged.

Description

technical field [0001] The invention relates to the field of lighting devices, in particular to a focusing laser lighting device. Background technique [0002] Flashlights are commonly used lighting equipment. Existing flashlights are generally spotlight flashlights or LED light-emitting diodes as lighting sources; LED light-emitting diodes are used as lighting sources. Advantages, but because the LED light-emitting diode converts a large part of the input electric energy into heat energy, the energy efficiency conversion rate is low, and serious energy waste occurs; the LED light-emitting diode has a small area and a high heat density, and poor heat dissipation leads to an increase in the junction temperature, which is serious It affects the luminous wavelength, luminous intensity, luminous efficiency and service life; at the same time, LED luminescence is astigmatism, which has defects such as diffusion, large volume, and insufficient irradiation distance. [0003] The fe...
