Embodiment Construction

[0018] It should be noted that the use of words such as "first" and "second" to define parts is only for the convenience of distinguishing corresponding parts. Limitation of the scope of protection of the invention.

[0019] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] It can be understood that the present invention achieves the purpose of the present invention through some embodiments.

[0021] Such as figure 1 As shown, the present invention provides a large-scale laser lighting structure, including: a laser 1, the laser 1 emits a beam; along the direction of the outgoing beam 10, a half-wave plate 2, a Galileo beam expander assembly, and a beam lifter 7 are sequentially arranged And the beam reflection assembly can form the outgoing beam into a large-scale laser illumination area; the half-wave plate 2 is a rotatable structure so that the polarization direction of the incident beam...

Abstract

The invention provides a large-range laser illumination structure, which comprises a laser device for emitting a light beam; a half-wave plate, a Galileo beam expanding assembly, a light beam lifting device and a light beam reflecting assembly are sequentially arranged in the direction of an outgoing light beam so that the outgoing light beam can form a large-range laser illumination area. The device is simple in structure, the light intensity and the divergence angle of a laser beam are continuously adjusted, the laser diffusion effect is good, and large-range laser illumination is achieved.

Description

technical field [0001] The invention relates to the technical field of laser lighting, in particular to a large-scale laser lighting structure. Background technique [0002] In recent years, for example, laser lighting devices using laser light as a light source have been used as illumination for vehicle-mounted peripheral monitoring sensors and monitoring sensors for monitoring people in hospitals, factories, facilities, and the like. [0003] In such a laser illuminating device, it is required to widen the width of the laser beam and irradiate it at a wide angle so as to monitor as wide an area as possible by laser light emitted from a single light source. Therefore, in the past, as a unit for diffusing laser light, for example, a diffuser plate that diffuses light has been used for diffusion, but the laser diffusion effect is not good, the illumination area is limited, and in such a laser illumination device, the light intensity and divergence angle cannot be achieved Co...
