Technical Field
[0001] This utility model belongs to the field of semiconductor laser application technology, and in particular relates to an ultra-narrow angle projection laser light. Background Technology
[0002] Currently, there are still several shortcomings in the floodlighting systems on the market. For example, as the distance increases, it is difficult to maintain the uniformity of the brightness at the center and the edge, making it impossible to achieve a balance between distance and uniformity. Moreover, the brightness loss is severe at long distances, making it difficult to meet the needs of certain special applications. In addition, most floodlighting systems use LED light sources, which perform poorly in terms of brightness and light spot uniformity, resulting in unsatisfactory quality of the projected light spot. Furthermore, in order to achieve high brightness and long distance, traditional floodlighting systems require larger heat sinks and more LEDs, resulting in a large lamp size.
[0003] This paper improves and upgrades the traditional projection system based on market demand. The brightness of the laser is much higher than that of the traditional LED. A single laser diode can generate an extremely strong beam, easily achieving ultra-long-distance wall washing at the level of hundreds of meters. Moreover, the brightness attenuation is much less than that of LED. This paper proposes a projection laser light with customizable angle, high brightness, good uniformity, small size, and the ability to meet special application scenarios. This utility model provides an ultra-narrow angle projection laser light. After the fiber optic output passes through the lens module, it emits a high-brightness uniform light spot, and the projection angle can be customized. Summary of the Invention

It solves the problem that existing projection systems have difficulty maintaining the uniformity of center and edge brightness as the distance increases, making it impossible to achieve a balance between distance and uniformity. Moreover, the brightness loss is severe at long distances, making it difficult to meet the needs of certain special applications. Most projection systems use LED light sources, which perform poorly in terms of brightness and spot uniformity, resulting in unsatisfactory projected spot quality. Furthermore, traditional projection systems require larger heat sinks and more LEDs to achieve high brightness and long distance, resulting in a large lamp size.

[0025] The working principle of this utility model: In use, external 220V AC power is input through power interface 19, and converted into a stable DC voltage required by various components in the system (such as laser light source 21, driver board, and fan) via power module 23 and DC step-down power module 22. Under the command of 512 control board 25, light source drive module 24 provides precise drive current to laser light source 21, exciting it to generate high-power laser. 512 control board 25 receives external control signals (such as DMX512 protocol) through 512 male connector 17 and female connector on the back, thereby precisely controlling laser light source 21. The laser light generated by the emission, blocking, and brightness changes is coupled into one end of the armored fiber 3. The yellow cladding on the outer layer of the armored fiber 3 protects the fragile inner fiber from excessive bending, damage, and dust intrusion. The two ends of the fiber are securely locked to the laser source system 2 and the lens system 1 respectively through waterproof connectors 4, ensuring stable connection and achieving IP protection level. The laser light is transmitted through the armored fiber 3 into the lens system 1 and enters the lens module 36. The lens module 36 is a core component with precise optical design, and its function is to diffuse the point-like laser light. The lens system 1 is homogenized to form a light spot with uniform brightness and clear edges. Depending on the application requirements, different optical lens modules 36 with varying divergence angles can be used to achieve different field of view (FOV) light spot effects, from narrow to wide angles, thus enabling customization of the projection angle. The shaped uniform light spot is emitted through the window mirror 5, which also seals the interior of the lens system 1, providing dust and water protection. The entire lens system 1 can be finely adjusted in multiple dimensions (up / down, left / right, and tilt) via its bottom three-dimensional adjustment bracket 6. This adjustment allows for precise control of the light spot's position. The position, shape, and illumination angle of the target plane or object can be adjusted and kept stable by tightening screws. The laser source 21 generates a large amount of heat during operation, as do other electronic components such as the power module 23 and drive module. These heat-generating components, especially the laser source 21, are tightly fixed to the heat sink 26 with screws. Thermal grease is applied to the contact surface to fill tiny gaps, ensuring efficient heat transfer from the heat-generating components to the heat sink 26. The heat sink 26 is designed with dense heat dissipation fins, greatly increasing the heat dissipation area in contact with the air. Four cooling fans 28 generate forced airflow to quickly blow away the heat from the fins, achieving convection cooling. The laser source system 2 generates a high-brightness laser, which is conducted to the lens system 1 through the armored optical fiber 3. After being shaped and projected by the lens module 36, it finally emits a high-brightness, uniform, and adjustable beam through the window mirror 5.
