[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] like Figure 1-4 As shown, an embodiment of the present invention provides a high and low beam lamp, including a lamp body 1. The lamp body 1 is provided with a circuit board 12 and at least one set of high and low beam lamps 11. A photosensitive sensor 121 is provided on the circuit board 12, with one end extending to one side of the lamp body 1.

[0029] The circuit board 12 integrates an automotive-grade MCU (microcontroller) which is responsible for processing sensor signals and controlling the switching of lights. If a signal of sudden brightening is detected, it is determined to be an oncoming vehicle and the low beam is switched immediately. If no signal of sudden brightening is detected and the light remains low, it is determined to be a dark environment and the high beam is switched to maintain high beam illumination.

[0030] The product uses a photosensitive sensor 121 to capture environmental information in real time, identify oncoming light sources, ambient light intensity, and the distance to obstacles in front, and automatically switch between high beam and low beam. The product features a simple structure, low manufacturing cost, stable performance, and low power consumption.

[0031] like Figure 3-4 As shown, in some embodiments, the high and low beam lamps 11 include a high beam lamp plate 111 disposed on one side of the circuit board 12 and a low beam lamp plate 112 disposed at the bottom of the circuit board 12.

[0032] The spatial separation layout of the high beam lamp panel 111 and the low beam lamp panel 112 eliminates optical crosstalk and ensures the purity of optical performance. The circuit board 12 serves as an installation reference surface to simplify the production and assembly process. The high beam lamp panel 111 directly forms a concentrated beam, while the low beam lamp panel 112 achieves wide-angle illumination through the reflective structure of the bottom low beam lamp cup 114.

[0033] like Figure 1-4 As shown, in some embodiments, the lamp body 1 includes an aluminum shell 13, and the interior of the aluminum shell 13 is provided with a transparent lens 14, a heat sink 15 and a battery 16 from front to back.

[0034] The axial stacking design of the internal components of the aluminum shell 13 optimizes the heat conduction path and mechanical stability. The rear-mounted battery 16 balances the overall center of gravity and improves vibration resistance. Heat is conducted to the outer surface of the aluminum shell 13 through the heat sink 15, forming a passive heat dissipation cycle.

[0035] like Figure 2-4 As shown, in some embodiments, one side and the bottom of the heat sink 15 are respectively attached to the high beam panel 111 and the low beam panel 112, and the other side of the heat sink 15 is attached to one side of the battery 16.

[0036] The multi-faceted contact design of the heat sink 15 enables bidirectional temperature management of the high beam board 111, the low beam board 112, and the battery 16. The heat sink 15 absorbs the heat generated by the LED beads and the heat generated by the discharge of the battery 16, and dissipates heat through the surface of the aluminum shell 13.

[0037] like Figure 3-4 As shown, in some embodiments, a lens 113 is provided on one side of the high beam headlight panel 111, with one end passing through the circuit board 12 and the transparent lens 14 and extending to the side of the aluminum shell 13. A low beam output port 141 is provided on one side of the transparent lens 14. A low beam lamp cup 114 is provided at the bottom of the low beam headlight panel 112. The opening of the low beam lamp cup 114 is angled towards the transparent lens 14 and opposite to the low beam output port 141. A lamp cup stud 115 is provided at one end of the low beam lamp cup 114. A light hole 116 is provided at both ends of the low beam lamp cup 114.

[0038] The inner wall of the low beam lamp cup 114 is arc-shaped. After the high beam lamp panel 111 is lit, the light is emitted as a concentrated beam through the lens 113. After the low beam lamp panel 112 is lit, the light is guided through the low beam lamp cup 114 to the low beam output port 141. Wide-angle illumination is achieved through the reflective structure of the low beam lamp cup 114.

[0039] like Figure 1-4As shown, in some embodiments, a transparent lens sealing ring 142 is provided on one side of the transparent lens 14, and a lower cover 17 is installed on the bottom of the aluminum shell 13 through a lower cover sealing ring 131. The top of the lower cover 17 is provided with a lower cover stud 171 whose top extends into the interior of the aluminum shell 13 and is coaxially opposite to the light cup stud 115.

[0040] The transparent lens sealing ring 142 is pressed between the transparent lens 14 and one side wall of the aluminum shell 13 to seal the holes of the photosensitive sensor 121 and the lens 113. A screw is inserted into the inside of the lower cover stud 171 from the bottom of the lower cover 17. One end of the screw is screwed into the inside of the light cup stud 115 to fix the lower cover 17. After the lower cover 17 is fixed, the lower cover sealing ring 131 is pressed to achieve the sealing of the lower part of the aluminum shell 13.

[0041] like Figure 2-4 As shown, in some embodiments, the top of the aluminum shell 13 is fitted with a top cover 18 via a top cover sealing ring 132. The bottom of the top cover 18 is provided with two top cover studs 181 extending into the interior of the aluminum shell 13. Both ends of the bottom of the heat sink 15 are provided with light holes 151. The light holes 151, light holes 116 and the top cover studs 181 are coaxial and opposite to each other.

[0042] A heat dissipation bracket 19 extends from the bottom of the top cover 18. The bottom end of the heat dissipation bracket 19 contacts the top of the heat sink 15. The heat of the heat sink 15 is conducted to the top cover 18 through the heat dissipation bracket 19, and then conducted to the surface of the aluminum shell 13 and the bracket 19 for heat dissipation. When assembling the product, the top cover 18 is installed first. Before the bottom cover 17 is installed, screws are inserted from the bottom of the aluminum shell 13 into the light hole 116 and the light hole 151 and screwed into the inside of the top cover stud 181. After the top cover 18 is fixed, the top cover sealing ring 132 is pressed to ensure the sealing of the top of the aluminum shell 13. Finally, the bottom cover 17 is installed.

[0043] like Figure 3-4 As shown, in some embodiments, the top of the cover 18 is fitted with a bracket 19 via a quick-release disc 182.

[0044] The quick-release plate 182 and the bracket 19 are fixed by a conventional twist-lock snap connection. The bracket 19 can be fixedly installed on motorcycles and electric vehicles as a headlight, and can also be used in bicycle lighting scenarios and auxiliary lighting scenarios for special engineering vehicles. The bracket 19 can also be in other forms.

[0045] like Figure 3-4As shown, in some embodiments, a charging interface 122 and a switch button 123 are integrated at both ends of one side of the circuit board 12, and waterproof plugs 133 and waterproof buttons 134 corresponding to the charging interface 122 and the switch button 123 are respectively provided on both sides of the aluminum shell 13. The circuit board 12 is electrically connected to the high and low beam lamps 11 and the battery 16.

[0046] The waterproof plug 133 is made of silicone, which ensures the sealing of the charging interface 122. By removing the waterproof plug 133, the battery 16 can be charged by connecting the power source and the charging interface 122 through the charging cable. The waterproof button 134 waterproofly seals the switch button 123, further improving the outdoor performance of the product.

[0047] In summary, the photosensitive sensor 121 detects ambient light and oncoming light sources in real time, enabling automatic switching between high and low beams. The main body 1 of the lamp adopts an axially stacked structure integrating an aluminum shell 13 with a transparent lens 14, a heat sink 15, and a battery 16. The heat sink 15 has a multi-faceted contact design to simultaneously conduct heat from the high and low beam lamps 11 and the battery 16. The entire system is waterproof and dustproof through the transparent lens sealing ring 142, the upper cover sealing ring 132, and the lower cover sealing ring 131. It features a compact structure, efficient heat dissipation, and easy assembly. While ensuring riding safety and avoiding glare, it significantly improves environmental adaptability and equipment reliability, and extends the lamp's service life.
