Abstract

The invention provides a novel laser street lamp which comprises a lamp shell, a radiating baffle, a laser lighting module and light transmitting face covers. The lamp shell and the radiating baffle are combined to form a cavity, the radiating baffle is connected with the light transmitting face cover, and one or more laser light modules is / are arranged below the light transmitting face cover. The laser lighting module comprises an optical device and a support, and the optical device is fixed to the support. The optical device comprises a laser light source, a collimating lens, a focusing lens, a fluorescent powder film, a secondary grading element TIR lens and a diffraction optical element which are sequentially arranged on the support from bottom to top. The novel laser street lamp is simple in structure, attractive, elegant, easy to maintain and controllable in cost; in addition, the luminous energy loss is greatly reduced, the efficiency for solar energy utilization is high, the directivity is good, the exposure distance is long, the production technology is simple, and the actual lighting requirement can be well met.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a novel laser street lamp. Background technique [0002] With the widespread application of light emitting diodes (Light Emitting Diode, LED) and laser diodes (Laser Diode, LD), lighting devices that use fluorescence generated by laser-excited phosphor powder as a light source are gradually becoming popular. Laser lighting devices that use lasers to excite phosphors to generate white light have also been further developed. Although LED has the advantages of long life, energy saving and environmental protection. However, white LEDs that use GaN blue chips as excitation devices have the problems of light decay, low photoelectric conversion efficiency, and unstable light color, and their light emission direction is not directional, which belongs to Lambertian light emission. As a new generation of phosphor excitation light source, laser has the advantages of stable li...
