[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1:

[0031] like Figures 1 to 5 As shown: A white laser motorcycle spotlight, comprising:

[0032] The lamp body 2 has a lamp chamber 10 and a control chamber 12 inside it;

[0033] White laser module 11, which is installed inside lamp chamber 10, is used to emit white laser light outward;

[0034] PCB board 13 is installed in the control room 12 and is electrically connected to the white laser module 11;

[0035] The light distribution structure is located inside the lamp chamber 10 and on the path of the white laser emitted by the white laser module 11, and distributes the light of the white laser.

[0036] Compared to LED or xenon lamps, white lasers offer higher luminous efficacy and greater brightness. Their strong directionality allows for longer illumination distances, improving safety during nighttime driving. Compared to traditional light sources, white lasers can achieve higher brightness with lower power consumption, improving energy efficiency. A PCB board 13, located within the control chamber 12 and electrically connected to the white laser module 11, drives its operation and may integrate temperature control and current regulation functions to ensure stable operation. A beam distribution structure, located within the lamp chamber 10 and along the white laser path, shapes, diffuses, or focuses the beam to optimize beam shape, improve illumination uniformity, and reduce glare and light pollution. White laser motorcycle spotlights are suitable for motorcycles in harsh environments or at high speeds, providing a superior lighting experience, especially at night or in extreme weather conditions.

[0037] In this embodiment, the light distribution structure includes:

[0038] Lens 8 is positioned in front of the white laser module 11 to focus the white laser.

[0039] The outer lamp cover is located outside the lamp chamber 10. The focused white laser beam illuminates the front of the vehicle through the outer lamp cover.

[0040] Lens 8 is mounted in front of the white laser module 11 to focus the white laser beam, making it more concentrated and improving illumination brightness and range. Through precise optical design, light energy loss is reduced and energy utilization is improved. An aspherical or freeform lens 8 can be used to optimize the beam shape and improve uniformity. After being focused by lens 8, the laser beam can illuminate a greater distance, improving safety during nighttime driving. The combination of lens 8 and the outer lamp cover effectively reduces hot spots, avoiding localized over-brightness or under-brightness and improving overall lighting performance. Combined with the high brightness of white laser light, the motorcycle spotlight can still provide clear illumination in low-visibility environments, significantly improving driving safety.

[0041] As a preferred embodiment of the above, the outer lamp cover 7 is a transparent yellow lamp cover, which converts the focused white laser into yellow light.

[0042] Yellow light has a longer wavelength (approximately 580-600nm), which reduces scattering in the air and makes it more effective than white light in foggy, rainy, and snowy conditions. By using a yellow filter, white laser light is converted into yellow light, improving its penetration and making it suitable for low-visibility environments such as rainy, foggy, and snowy days. It reduces light scattering, improves road visibility, and is softer than blue-white light, making it less likely to cause driver visual fatigue.

[0043] As a preferred embodiment of the above, the outer lamp cover 7 is a transparent floodlight cover, which floods the focused white laser.

[0044] Through a special optical diffusion design, the light is distributed more evenly, reducing strong focal points and forming a wider illumination area, providing large-area lighting. It is suitable for close-range night riding or complex road conditions. In situations where wide-angle lighting is needed, such as in urban areas, curves, and rugged mountain roads, it can provide a safer field of vision, prevent excessively concentrated beams from interfering with oncoming vehicles, and improve driving safety.

[0045] The outer lamp cover 7 is attached to the lamp body 2 by snap-fit, and the outer lamp cover 7 can be disassembled and replaced by snap-fit.

[0046] The outer lamp cover 7 and the lamp body 2 adopt a snap-fit ​​structure, which can be installed and removed without additional tools. The design is a slot + elastic buckle to ensure a stable installation. At the same time, it is convenient for users to replace different types of lamp covers. Users can change them according to their needs without having to buy multiple different lamps. They only need to replace the lamp cover 7 to adapt to different environments.

[0047] In this embodiment, a through hole 16 is provided between the lamp chamber 10 and the control chamber 12, and a wire is provided between the PCB board 13 and the white laser module 11, with the wire passing through the through hole 16.

[0048] The through-hole 16+ wire connection design ensures stable communication and power supply between the PCB board 13 and the white laser module 11, while also improving protection, heat dissipation, and ease of maintenance. Suitable for high-brightness motorcycle spotlights, it ensures stable operation in various harsh environments, enhancing the overall safety and reliability of the light.

[0049] As a preferred embodiment of the above embodiment, the lamp body 2 further includes a front cover 1 and a rear cover 3. The front cover 1 and the rear cover 3 are respectively disposed in front of and behind the lamp body 2 when the vehicle is traveling. A waterproof rubber ring 159 is provided between the front cover 1 and the lamp body 2. The rear cover 3 is provided with a through hole 16 and a vent hole 5. The through hole 16 is used for the PCB board 13 to be electrically connected to the vehicle. A waterproof rubber gasket 14 is provided between the rear cover 3 and the lamp body 2.

[0050] The front cover 1, tail cover 3, waterproof rubber ring 159, and waterproof rubber pad 14 significantly improve the waterproof, dustproof, shockproof, and heat dissipation capabilities of the lamp body 2. The optimized design of the through hole 16 and vent hole 5 ensures stable electrical connection, while preventing fogging and heat accumulation, improving the durability of the spotlight. It can be used in various harsh environments such as long-distance travel, high temperature, water crossing, and bumpy road sections, meeting the high-performance requirements of motorcycle spotlights and ensuring that users can obtain a stable and safe lighting experience under various extreme conditions.

[0051] In this embodiment, the tail cover 3 is also provided with several grooves.

[0052] The grooves can increase the surface area of ​​the tail cover 3, improve air convection efficiency, and accelerate heat dissipation. They are suitable for high-temperature environments and ensure that the tail cover will not overheat during long-term use. By optimizing the groove layout, the weight of the lamp body 2 can be reduced without affecting the structural strength, thus reducing the burden on the vehicle.

[0053] Among them, the white laser module 11 is a reflective light source.

[0054] The reflective light source design in the white laser module 11 ensures that even if the phosphor sheet in the white laser module 11 falls off, there will be no risk of high-energy blue light being emitted directly, thus ensuring safety during use.

[0055] As a preferred embodiment of the above, the PCB board 13 includes a white laser constant current driving circuit.

[0056] Constant current drive ensures that the white laser module 11 operates within a stable current range, preventing brightness fluctuations or flickering. Constant current control prevents current overshoot, reduces overheating damage to the laser module, and extends the lifespan of the spotlight. The use of a high-efficiency constant current circuit reduces energy loss, optimizes power consumption, and improves motorcycle battery life. It is suitable for complex motorcycle circuit environments (such as engine electromagnetic interference), ensuring stable operation of the light source under various road conditions.

[0057] Example 2:

[0058] This utility model provides, for example Figures 1 to 5 The illustrated white laser motorcycle spotlight includes a lamp body 2, inside which are a lamp chamber 10 and a control chamber 12, with a through hole between the control chamber 12 and the lamp chamber 10. A reflective white laser module 11 is mounted on the lamp chamber 10, and a PCB board 13 is mounted in the control chamber 12. The white laser module 11 and the PCB board 13 are connected by wires passing through the through hole 16. A lens 8 is mounted at the front of the lamp body 2, and a front cover 1 is placed in front of the lens 8. The front cover 1 is threaded to the lamp body 2, and waterproof gaskets are placed between the front cover 1 and the lens 8, and between the front cover 1 and the lamp body 2, for waterproof sealing. A tail cover 3 is mounted at the rear of the lamp body 2, and the tail cover 3 is threaded to the lamp body 2 and sealed with a waterproof gasket 14. The tail cover 3 has a through hole, and the PCB board 13 is electrically connected to the motorcycle body by wires passing through the through hole 6 of the tail cover 3.

[0059] In the above technical solution, the light distribution structure includes a lens 8, a transparent outer lamp cover 7, and a transparent yellow outer lamp cover. The lens 8 is installed in front of the lamp body 2 via a threaded connection and is non-removable. It is also located in front of the white laser module 11. The white laser module 11 emits white laser light forward, which is focused by the lens 8 to achieve a focused light mode. The transparent yellow outer lamp cover is installed in front of the lamp body 2 via a snap-fit ​​and is detachable. In the focused light mode, it converts white light into yellow light, increasing fog penetration. The transparent outer lamp cover 7 is installed in front of the lamp body 2 via a snap-fit ​​and is detachable. It is located in front of both the white laser module 11 and the lens 8. The white laser module 11 emits laser light forward, which is focused by the lens 8 and then flooded by the transparent outer lamp cover 7 to achieve a floodlight mode. The two modes can be switched to meet the needs of different occasions such as highways and urban areas.

[0060] Among them, PCB board 13 adopts a drive control circuit with automotive-grade components, such as... Figure 5 As shown, it includes reverse connection protection, undervoltage protection, EMC design, and active thermal management control, which effectively improves the reliability of the lamp and ensures stable laser output.

[0061] In the above technical solution, the lamp body 2 has a streamlined design, and the tail of the lamp body 2 has grooves in many places to increase the contact area between the lamp body 2 and the air, so that the lamp has a good heat dissipation effect.

[0062] In the above technical solution, threaded holes are provided on both sides of the lamp body 2, and the bracket 4 is threadedly connected to the vehicle lamp through the threaded holes at both ends. The bottom of the bracket 4 is provided with a through hole for fixing to the motorcycle.

[0063] The white laser module 11 uses a reflective light source, which effectively avoids the harm of blue laser light.

[0064] Working Principle: By installing a white laser module 11 inside the lamp chamber 10 to replace conventional halogen, xenon, or LED lamps, the illumination distance and brightness of the motorcycle light are improved. With the use of a light distribution structure, the white laser motorcycle spotlight can switch modes to meet different lighting needs at high speeds and in urban areas. The lens 8 in the light distribution structure is installed in front of the white laser module 11 to focus the white laser emitted by the module, achieving a focused beam mode. In this mode, the laser emitted by the motorcycle spotlight has a central luminous intensity of 300,000 cd, a maximum illumination distance of 1500m at the 0.251x isolux line, a maximum longitudinal width of 3m at 10m in front of the light, 15m at 50m in front of the light, and 25m at 100m in front of the light. When the transparent outer lamp cover 7 in the light distribution structure is installed, a floodlight mode can be achieved. In this mode, the laser emitted by the motorcycle spotlight has a central luminous intensity of 45,000 cd, a maximum illumination distance of 600m at the 0.251x isolux line, a maximum longitudinal width of 8m at 10m in front of the light, 40m at 50m in front of the light, and 80m at 100m in front of the light. The white laser module 11 adopts a reflective design, effectively reducing the harm of blue laser light.
