Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting technology, specifically relating to a direct-insertion dual-lamp board automotive lamp with built-in fan for heat dissipation. Background Technology

[0002] With the development of automotive lighting technology, LED light sources have gradually become the mainstream choice for automotive headlights due to their advantages such as high brightness, long lifespan, and low energy consumption. In order to improve lighting effects and lamp compatibility, LED automotive lights with double-sided light source panels have gradually appeared on the market. These lights use two light source panels to work together to emit light, thereby improving the beam angle and illumination range.

[0003] In existing technologies, there are mainly two structural forms:

[0004] The method of using a half-heat sink with a light source board and a built-in fan to actively dissipate heat and reduce the thermal decay of LED light source is adopted. However, the heat sink of this type of structure has limited size and the heat dissipation efficiency is still not ideal. In addition, the heat dissipation conditions are limited because it is equipped with only one light source board.

[0005] Using an integrated heat sink in conjunction with two interlocking light source boards can achieve symmetrical lighting. However, most of these structures are not equipped with fans and rely solely on the metal heat sink for natural heat dissipation, which is difficult to meet the heat dissipation requirements of high-power LEDs for continuous operation. Long-term use can easily lead to problems such as light decay, overheating of the control circuit, or even damage.

[0006] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0019] like Figures 1 to 3 As shown, a direct-insertion dual-lamp panel automotive lamp with built-in fan cooling includes a lamp housing 10. The rear end of the lamp housing 10 has a component mounting section 11, in which a cooling fan 20, a control circuit board 30, and a conductive plug 40 are respectively mounted. The cooling fan 20, the control circuit board 30, and the conductive plug 40 are arranged sequentially. The front end of the component mounting section 11 has a light source mounting section 12. A first light source plate 50 is mounted on the upper surface of the light source mounting section 12, and a second light source plate 60 is mounted on the lower surface of the light source mounting section 12. The first light source plate 50 and the second light source plate 60 are symmetrically arranged, effectively improving illumination. Regarding the angle and brightness, the control circuit board 30 is electrically connected to the conductive plug 40, the cooling fan 20, the first light source board 50, and the second light source board 60, respectively. In use, the user can directly insert the conductive plug 40 into the original car lamp socket. After the power is turned on, the control circuit board 30 starts the first light source board 50 and the second light source board 60 for illumination, and at the same time controls the cooling fan 20 to run. The fan quickly draws heat away from the vicinity of the light source board and the circuit board and discharges it through the heat dissipation openings of the lamp housing 10, thereby effectively improving heat dissipation efficiency, preventing LED overheating and light decay, and ensuring stable and reliable operation of the car lamp under high brightness and high power conditions.

[0020] In practical implementation, the inner side of the mounting part 11 of the component is recessed with a positioning slot 111, in which a mounting bracket 70 is fitted. The mounting bracket 70 is connected to the first light source plate 50 and the second light source plate 60 respectively. In use, the mounting bracket 70, in conjunction with the limiting function of the positioning slot 111, enables the entire light source component to have good structural stability and durability, facilitates mass assembly, and also improves the shock resistance and service life of the automotive lamp.

[0021] In specific implementation, the upper surface of the light source mounting part 12 is recessed with a first light source groove 121, the size of which is larger than the size of the first light source plate 50. The first light source plate 50 is embedded in the first light source groove 121. The lower surface of the light source mounting part 12 is recessed with a second light source groove 122, the size of which is larger than the size of the second light source plate 60. The second light source plate 60 is embedded in the second light source groove 122. A fixing through hole 123 is provided between the first light source groove 121 and the second light source groove 122. A first light source plate 50 is formed on its surface. Mounting through holes 51 are provided on the surface of the second light source board 60. The first mounting through hole 51 and the second mounting through hole 61 are correspondingly located at both ends of the fixing through hole 123, and are connected and fixed by fasteners passing through the first mounting through hole 51, the fixing through hole 123, and the second mounting through hole 61. This structural design reliably mounts the first light source board 50 and the second light source board 60 on both sides of the light source mounting part 12, improving installation strength and shock resistance, and ensuring that the light source board will not loosen or shift due to thermal expansion or vibration during operation, thus enhancing the stability and service life of the entire lamp. In use, this structure also facilitates disassembly and maintenance. When the light source board is damaged or needs replacement, only the fasteners need to be removed to complete the replacement, improving maintenance convenience and product versatility.

[0022] In practical implementation, the front and rear sides of the component mounting part 11 are evenly provided with a plurality of fan heat dissipation holes 112 and a plurality of circuit board heat dissipation holes 113. The fan heat dissipation holes 112 correspond to the position of the cooling fan 20 and are used to guide cold air in or hot air out. The circuit board heat dissipation holes 113 correspond to the position of the control circuit board 30 and are used to enhance air circulation around the circuit board and improve the overall heat dissipation performance. The rear ends of the first light source groove 121 and the second light source groove 122 are evenly provided with air inlet openings 124. The setting of the air inlet openings 124 facilitates the cooling fan 20 to further guide cold air into the area where the light source board is located when it is working, effectively increasing the airflow speed in the LED chip area, thereby enhancing the heat dissipation effect of the upper and lower light source boards. Through the above structural design, the car light can form a complete airflow path during operation: cold air is introduced from the air inlet 124 behind the light source recess, passes through the surface of the light source board, the control circuit board and the fan area, and is discharged through the fan heat dissipation hole 112 and the circuit board heat dissipation hole 113 respectively, thereby realizing a stable and reliable active convection heat dissipation system, and further ensuring the thermal balance of the light source and the control system under long-term working conditions.

[0023] In summary, the rear end of the lamp housing 10 is provided with a component mounting section 11, in which a cooling fan 20, a control circuit board 30, and a conductive plug 40 are respectively installed. The front end of the component mounting section 11 is provided with a light source mounting section 12, on which a first light source board 50 is mounted on the upper surface and a second light source board 60 is mounted on the lower surface. The plug-in dual-lamp board automotive lamp of this utility model combines the corresponding air duct design of the fan, circuit board, and light source board to realize a plug-in mounting structure and dual-light source symmetrical lighting. Furthermore, the built-in fan and heat dissipation holes work together to achieve active and efficient heat dissipation, which greatly improves the working stability and service life of the LED.
