Based on market demand, this invention upgrades traditional laser lights, proposing a wide-field-of-view laser wide-angle projection system that can meet the pattern effects of various scenarios. This invention provides an ultra-wide-angle laser wide-angle projection system with a divergence angle of fiber optic output that is much larger than that of free spatial output.

[0003] To address the problems of existing technologies, this invention provides an ultra-wide-angle laser projection system. It features a divergence angle from fiber optic output that is significantly greater than that of free spatial output. Through secondary amplification via the wide-angle system, it can ultimately achieve a 180° wide-angle output. Furthermore, it boasts a large field of view for the output beam, variable pattern effects, and customizable projection angle. This solves the problems of existing laser systems, which are mostly free-range with small divergence angles, unable to meet the demands for large-angle projection, struggling to achieve ultra-wide-angle output, and limited pattern effects and field of view. Traditional laser lights also have small pattern fields of view, unable to cover the needs of various scenarios for large-field-of-view patterns, and have fixed projection angles that are difficult to adjust flexibly according to different scenarios.

[0009] As a preferred embodiment of this invention, the laser wide-angle projection system emits light from the red, green, and blue light source modules, which are then combined and coupled into the optical fiber by the beam combining module before exiting through the armored optical fiber. After collimation, the light spot strikes the XY mirror of the galvanometer system and is emitted as an image. The light is then output through the wide-angle system for beam expansion imaging.

[0010] With this setup, light is emitted from red, green, and blue light source modules, then combined and coupled into an optical fiber by a beam combining module before exiting through an armored optical fiber. The armored optical fiber is then connected and locked to the rear end of a collimating lens. After collimation, the light spot strikes the XY mirrors of the galvanometer system.

Different divergence angles of the wide-angle system can be replaced according to different field-of-view requirements to achieve different pattern effects and thus achieve the desired light spot. This realizes wide-angle laser projection based on fiber collimation and galvanometer scanning.

The galvanometer power supply and the galvanometer driver ensure the stable operation of the galvanometer system.

[0018] This setting facilitates power supply and helps ensure the stable operation of the galvanometer system.

[0019] As a preferred embodiment of this utility model, a 220V power interface is provided on the rear panel, and the power interface enables 220V power supply.

[0020] This setting allows for convenient control of the laser output on / off.

[0021] As a preferred embodiment of this invention, the armored optical fiber has a yellow armor cladding layer on the outside.

[0022] This setting provides a certain degree of protection for the optical fiber by preventing dust from entering it and avoiding damage caused by excessive bending.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is an improvement and upgrade based on the traditional laser lamp according to market demand. The divergence angle of the fiber output is much greater than that of free spatial output. Moreover, through secondary amplification by the wide-angle system, a 180° large-angle output can be achieved.

Utilizing fiber optic collimation and galvanometer scanning technology, the pattern effect is variable, and the divergence angle of the wide-angle system can be customized to meet the needs of various scenarios. The core optical components are precisely designed and reinforced, ensuring excellent optical axis consistency. The aluminum alloy material and silicone rubber protection achieve IP65 waterproof and dustproof performance. Combined with efficient heat dissipation and stable power supply, the equipment's reliability is enhanced. The modular design reduces maintenance time and supports customization of parameters such as the light source, fiber optics, and galvanometer, balancing production efficiency and application flexibility, and comprehensively optimizing the performance and adaptability of the laser projection system.
