Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, specifically to an integrated vehicle lighting system for buses with a surface heat dissipation structure. Background Technology

[0002] Integrated bus headlights provide sufficient road illumination during nighttime driving, ensuring drivers can clearly see road conditions within a safe distance. As a holistic optical system, integrated headlights better consider light distribution and reflection. Through precise optical simulation and design, light loss is reduced, improving lighting efficiency. However, integrated bus headlights generate heat during operation. If this heat cannot be effectively dissipated, the temperature inside the headlight will rise sharply. High temperatures accelerate chip aging, ultimately leading to frequent headlight replacements and increasing maintenance and operating costs.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number CN201921039321.7, application date 2019-07-05) provides an integrated vehicle light. In use, a locking block is inserted through a through-hole into a stepped cavity on the edge of the fan cover. Further pressing causes the T-shaped movable block to elastically deform the spring, allowing the locking block to engage precisely in the stepped cavity. The rotating hollow column causes the universal ball bearings to rotate within the stepped cavity, and the protrusion engages precisely in the first circular groove, thus fixing the vehicle light in place. Meanwhile, the fan operates, dissipating heat from the housing containing the lamp body through ventilation and heat dissipation holes. This prevents excessively high local temperatures and extends the lifespan of the vehicle light.

[0004] Although existing technology can dissipate heat from vehicle lights, when the lights operate for a long time and generate excessive heat, it is inconvenient to dissipate the heat effectively, which will cause the temperature to rise continuously, reduce the luminous efficiency of the LED chips, and cause the color temperature of the LED chips to change due to prolonged high temperature, affecting the lighting effect and visual clarity. Utility Model Content

[0005] The purpose of this invention is to provide an integrated bus headlight with a surface heat dissipation structure to solve the problem mentioned in the background art, which is that the temperature rises continuously, reducing the luminous efficiency of the lamp beads, causing the color temperature of the lamp beads to change, and affecting the lighting effect and visual clarity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated bus headlight with a surface heat dissipation structure, comprising a headlight column, with LED beads fixedly connected to both sides of the headlight column, a headlight holder fixedly connected to the bottom of the headlight column, a mounting base installed at the bottom of the headlight holder, and a drive module fixedly installed at the bottom of the mounting base; the outer wall of the drive module is provided with a heat dissipation component for reducing the headlight temperature, the heat dissipation component includes a mounting shell fixedly connected to the outer wall of the drive module, a cooling fan installed at the bottom of the mounting shell, a condenser pipe fixedly connected to the inner wall of the mounting shell, and condensate flowing inside the condenser pipe; a cooling water supply device for collecting and discharging condensate is fixedly installed on the outer wall of the mounting shell; a plurality of heat dissipation fins are provided on the outer wall of the drive module, and the heat dissipation fins are evenly arranged around the center of the drive module; and a disassembly and assembly component for disassembling and assembling the headlight is provided between the mounting base and the headlight holder.

[0007] Furthermore, the assembly and disassembly assembly includes two connecting blocks fixedly connected to the bottom of the lamp holder. The mounting base has a sliding cavity inside. A fixing rod is fixedly connected to the inner wall of the sliding cavity. A slider is slidably installed on the outer wall of the fixing rod. A spring is fixedly connected to one side of the slider, and the end of the spring away from the slider is fixedly connected to the inner wall of the sliding cavity. A control block is fixedly connected to the other side of the slider. Two protrusions are fixedly connected to the top of the slider.

[0008] Furthermore, the bottom of the mounting shell is provided with a mounting groove, and the cooling fan is fixedly installed inside the mounting groove. The air inlet end of the cooling fan is provided with a filter plate.

[0009] Furthermore, the inner bottom wall of the mounting shell is provided with an air inlet communicating with the mounting groove, and the mounting shell is provided with a plurality of evenly distributed air outlets.

[0010] Furthermore, a limiting groove is provided through the side wall of the connecting block. When the lamp post is in the locked state, the outer wall of the protrusion is slidably connected to the inside of the limiting groove. The top of the mounting base is provided with two through grooves communicating with the sliding cavity, and the bottom of the connecting block is slidably inserted into the inside of the sliding cavity through the through groove.

[0011] Furthermore, the side wall of the mounting base is provided with a sliding cavity communicating with a sliding groove, and one side of the control block is fixedly connected to the side wall of the slider through the sliding groove.

[0012] Furthermore, the protrusion is L-shaped, and the sidewalls of the protrusion are arc-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The bus integrated headlight with surface heat dissipation structure can continuously release cold air in the mounting shell and exchange heat with the drive module in cooperation with the cooling water supply device and condenser pipe. At the same time, the heat dissipation fins can accelerate the heat dissipation of the drive module. When the cooling fan is turned on, the purified external air can be blown into the mounting shell. Under the action of the cooling fan, the heat inside the mounting shell is blown out, thereby further dissipating heat and preventing the headlight temperature from rising, which would cause the color temperature of the lamp to change.

[0015] (2) The bus integrated headlight with surface heat dissipation structure can quickly detach and install the lamp post and drive module by pressing the control block, with the cooperation of the slider, spring, protrusion and connecting block. Thus, when the headlight has a problem, the lamp bead and drive module can be quickly separated for inspection, and a certain component can be repaired or replaced separately, reducing maintenance costs.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a bus integrated headlight with a surface heat dissipation structure, including a lamp post 1, lamp beads 2 fixedly connected to both sides of the lamp post 1, a lamp holder 3 fixedly connected to the bottom of the lamp post 1, a mounting base 4 installed at the bottom of the lamp holder 3, and a drive module 10 fixedly installed at the bottom of the mounting base 4.

[0025] When the vehicle lights are needed to operate, the drive module 10 can provide suitable electrical energy to the lamp beads 2, which can convert the vehicle power supply into the current and voltage required by the lamp beads 2. By connecting the mounting bracket 4 and the lamp holder 3, it can be used to fix the lamp post 1 and provide electrical connection for the lamp beads 2. Finally, the lamp beads 2 convert electrical energy into light energy to produce the light required for illumination.

[0026] Example 2:

[0027] Based on Embodiment 1, by setting up a heat dissipation component, the temperature of the vehicle headlight can be prevented from rising, which would cause a change in the color temperature of the LED bead 2. The specific structure is as follows: The outer wall of the drive module 10 is provided with a heat dissipation component for reducing the temperature of the vehicle headlight. The heat dissipation component includes a mounting shell 7 fixedly connected to the outer wall of the drive module 10. A cooling fan 13 is installed at the bottom of the mounting shell 7. A condenser pipe 15 is fixedly connected to the inner wall of the mounting shell 7, and condensate flows inside the condenser pipe 15. A cooling water supply device 9 for collecting and discharging condensate is fixedly installed on the outer wall of the mounting shell 7. Several heat dissipation fins 6 are provided on the outer wall of the drive module 10, and the heat dissipation fins 6 are evenly arranged around the center of the drive module 10. A mounting groove 16 is opened at the bottom of the mounting shell 7, and the cooling fan 13 is fixedly installed inside the mounting groove 16. A filter plate is provided at the air inlet end of the cooling fan 13. An air inlet 14 communicating with the mounting groove 16 is opened on the inner bottom wall of the mounting shell 7, and multiple evenly distributed air outlets 8 are opened on the mounting shell 7.

[0028] When the headlights generate a lot of heat, the cooling fan 13 can be activated to blow outside air into the mounting housing 7 through the air inlet 14. At the same time, the filter plate at the air inlet of the cooling fan 13 can filter the outside air. Meanwhile, the cooling water supply device 9 continuously provides condensate to the condenser pipe 15, so that it can continuously release cool air into the mounting housing 7 to exchange heat generated by the drive module 10. At the same time, several heat dissipation fins 6 on the outer wall of the drive module 10 can accelerate the dissipation of heat inside the drive module 10. Finally, under the action of the cooling fan 13, the heat inside the mounting housing 7 can be discharged through multiple air outlets 8, thereby preventing the temperature inside and on the surface of the drive module 10 from being too high, which would cause the color of the light emitted by the lamp bead 2 to deviate, affecting the lighting effect and visual experience.

[0029] Example 3:

[0030] Based on Embodiment 2, by setting a disassembly and assembly component, the LED bead 2 can be separated from the drive module 10, allowing for individual repair or replacement of one of them. The specific structure is as follows: A disassembly and assembly component for disassembling and assembling the LED bead 1 is provided between the mounting base 4 and the lamp holder 3. The component includes two connecting blocks 11 fixedly connected to the bottom of the lamp holder 3. A sliding cavity 21 is provided inside the mounting base 4. A fixing rod 18 is fixedly connected to the inner wall of the sliding cavity 21. A slider 17 is slidably mounted on the outer wall of the fixing rod 18. A spring 20 is fixedly connected to one side of the slider 17, and the end of the spring 20 away from the slider 17 is fixedly connected to the inner wall of the sliding cavity 21. The other side of the slider 17... A control block 5 is fixedly connected to one side, and two protrusions 19 are fixedly connected to the top of the slider 17. A limiting groove 12 is opened through the side wall of the connecting block 11. When the lamp post 1 is in the locked state, the outer wall of the protrusion 19 is slidably connected to the inside of the limiting groove 12. Two through grooves 22 communicating with the sliding cavity 21 are opened on the top of the mounting base 4, and the bottom of the connecting block 11 is slidably inserted into the inside of the sliding cavity 21 through the through groove 22. A sliding groove 23 communicating with the sliding cavity 21 is opened through the side wall of the mounting base 4, and one side of the control block 5 is fixedly connected to the side wall of the slider 17 through the sliding groove 23. The protrusion 19 is L-shaped, and the side wall of the protrusion 19 is arc-shaped.

[0031] When the headlights malfunction, pressing the control block 5 moves the slider 17 around the fixed rod 18, compressing the spring 20 and simultaneously moving the two protrusions 19 away from the two connecting blocks 11, releasing the fixation on the lamp holder 3. Then, the two connecting blocks 11 slide out of the sliding cavity 21, allowing the lamp bead 2 or the drive module 10 to be repaired or replaced individually, thus reducing maintenance costs. Finally, the two connecting blocks 11 are inserted into the sliding cavity 21, and then the control block 5 is released, causing the spring 20 to return to its original state and move the slider 17, allowing the two protrusions 19 to slide into the two connecting blocks 11, thereby fixing the lamp holder 3. The sidewalls of the protrusions 19 are designed to be arc-shaped to ensure greater stability when they enter the connecting blocks 11.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
