Description

Technical Field

[0001] The utility model relates to the field of vehicle lamps, in particular to a vehicle lamp with a heat dissipation structure. Background Art

[0002] Modern headlights, especially LED headlights and xenon headlights, are widely used in various vehicles due to their high brightness and long life. However, high brightness also means high power consumption, which in turn generates a lot of heat. If this heat cannot be dissipated in time, it will cause damage to the electronic components inside the headlights.

[0003] The electronic components inside the headlights, such as LED chips and drive circuits, have a certain operating temperature range. If they work in a high temperature environment for a long time, the performance of these components will decline or may even fail. Therefore, by using a heat dissipation system to reduce the temperature inside the headlights, the service life of these components can be extended, thereby ensuring the stability and reliability of the headlights.

[0004] For LED headlights, high temperature can also lead to light decay. Light decay refers to the phenomenon that the brightness of LED lights gradually decreases after being lit for a period of time. This is because the LED chip works at high temperature, and the efficiency of electron and hole recombination inside it decreases, resulting in a decrease in luminous efficiency. Therefore, reducing the operating temperature of the LED chip through heat dissipation can effectively slow down the speed of light decay and maintain the brightness of the headlights.

[0005] Headlights are important safety components during vehicle driving. Their stability and reliability are directly related to the vehicle's driving safety. If the headlights fail or their performance deteriorates due to overheating, it will increase the risk of vehicle driving. Therefore, ensuring the normal operation of the headlights through a heat dissipation system is of great significance to improving the safety of vehicle driving.

[0006] Traditional headlights mostly dissipate heat actively through the operation of fans, which cannot change the working mode according to the driving conditions of the vehicle, consume a lot of energy, and easily cause the fan to be damaged due to long-term operation.

[0007] Therefore, it is necessary to propose an automobile lamp with a heat dissipation structure to solve the above problems. Utility Model Content

[0019] Technical effects and advantages of the utility model:

[0020] 1. The device collects and guides the airflow during driving by setting an air inlet shell and an air outlet shell. On the one hand, this method can prevent the airflow from entering the air outlet shell during driving, ensuring the smoothness of gas flow. The air inlet shell and the air outlet shell are close to the surface of the light-transmitting lampshade, and the contact area is large, so the airflow can cool the inside of the light-transmitting lampshade when it flows. On the other hand, the blown airflow will be blown along the surface of the light-transmitting lampshade, which can remove fog and dust from the outer wall of the light-transmitting lampshade. The temperature can be reduced only when the car is driving normally, without the need for power components, thereby reducing energy consumption.

[0021] 2. The device can cool down the inside of the light-transmitting lampshade while cooling down the lighting component by setting a ventilation pipe. If you do not want to cool down the inside of the light-transmitting lampshade, you only need to rotate the lighting component so that the second ventilation hole and the first ventilation hole are staggered. At this time, the gas inside the light-transmitting lampshade cannot be sucked out. At this time, the ventilation pipe can also play a protective role, preventing the light-transmitting lampshade from being broken by air pressure due to the temperature rise of the light-transmitting lampshade. The ventilation pipe can eliminate the pressure generated by the thermal expansion and contraction of the air, and the ventilation pipe draws air from the inside of the car to reduce the possibility of dust and other debris entering the light-transmitting lampshade.

[0022] 3. This device is equipped with a recovery component. When the car is driving, the fan can be driven to recover kinetic energy and then charge the battery. When the car is stationary, the battery will supply the electric energy required for the fan to work. Then, the working mode can be changed according to the driving state of the car. The kinetic energy generated by the airflow can be converted and collected when driving, and active cooling protection can be generated when the car stops to ensure working stability.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The utility model provides Figures 1 to 8The automobile lamp with a heat dissipation structure shown in the figure comprises a translucent lampshade 1, an air inlet shell 2 is fixedly mounted on the lower surface of the translucent lampshade 1, an air outlet shell 3 is fixedly mounted on the upper surface of the air inlet shell 2, two evenly distributed cooling shells 4 are fixedly mounted on one side of the translucent lampshade 1, a fixed shell 41 is fixedly mounted on the middle part of the cooling shell 4, a lighting component 5 is detachably and rotatably mounted inside the fixed shell 41, an air collecting scoop 21 is integrally formed on one side of the air inlet shell 2, two connecting grooves 22 corresponding to the cooling shell 4 are provided on the side of the air inlet shell 2 away from the air collecting scoop 21, and the air inlet shell 2 is provided with a plurality of connecting grooves 22. A triangular guide block 23 is fixedly installed at the middle position of the interior, an inclined plate 31 is integrally formed at one end of the air outlet shell 3, an end of the air outlet shell 3 close to the inclined plate 31 has an air outlet 32, and two connecting grooves 22 corresponding to the cooling shell 4 are also provided on the side of the air outlet shell 3 close to the cooling shell 4, a first connecting groove 42 is provided at a position corresponding to the air inlet shell 2 on one side of the cooling shell 4, a second connecting groove 43 is provided at a position corresponding to the air outlet shell 3 on one side of the cooling shell 4, the first connecting groove 42 is communicated with the interior of the air inlet shell 2, and the second connecting groove 43 is communicated with the interior of the air outlet shell 3.

[0034] In actual use, when the vehicle is driving, the air inlet shell 2 can collect the airflow and transport it to the interior of the cooling shell 4, and then pass through the cooling shell 4 into the interior of the air outlet shell 3. Because of the wind collecting scoop 21, the air inlet shell 2 can collect more airflow. Since the height of the wind collecting scoop 21 is greater than the height of the air inlet shell 2, the airflow entering the air inlet shell 2 is accelerated due to the reduced cross-section, and the air inlet shell 2 can further guide the airflow into the interior of the cooling shell 4, and the triangular guide block 23 gradually reduces the cross-section of the air inlet shell 2, so the airflow entering the cooling shell 4 will be further accelerated, the lighting component 5 can provide lighting, and the airflow passing through the lighting component 5 can cool the lighting component 5, and one end of the air outlet shell 3 has an inclined plate 31, so the airflow will be inclined by the inclined plate 3 during driving. 1 is pushed open, so that the airflow velocity on one side of the inclined plate 31 is greater, and then the air pressure at the position of the inclined plate 31 is reduced, so that the air inside the air outlet shell 3 is sucked out through the air outlet 32, so that the air circulation is smoother, and the airflow introduced by the air inlet shell 2 flows out through the inclined plate 31, and the air outlet 32 ​​can guide the airflow to fit the surface of the light-transmitting lampshade 1 and blow it out. On the one hand, this method can prevent the airflow from entering the air outlet shell 3 during driving, and ensure the smoothness of gas flow. The air inlet shell 2 and the air outlet shell 3 are close to the surface of the light-transmitting lampshade 1, and the contact area is large, so the airflow can cool the inside of the light-transmitting lampshade 1 when it flows. On the other hand, the blown airflow will be blown out along the surface of the light-transmitting lampshade 1, which can defog and remove dust from the outer wall of the light-transmitting lampshade 1, and the cooling can be performed only when the car is driving normally, without the need for power components, thereby reducing energy consumption.

[0035] A first placement groove 11 is provided at a position corresponding to the fixed housing 41 of the light-transmitting lampshade 1, a second placement groove 12 is provided at a middle position inside the first placement groove 11, a plurality of first ventilation holes 13 are provided inside the first placement groove 11, the lighting component 5 includes a mounting plate 51, a lamp board 52 is provided on one side of the mounting plate 51, a plurality of evenly distributed heat sinks 53 are fixedly installed between the mounting plate 51 and the lamp board 52, the lamp board 52 is located inside the first placement groove 11, the mounting plate 51 is detachably rotatably mounted inside the fixed housing 41, and a plurality of heat sinks 53 corresponding to the first ventilation holes 13 are provided on the lamp board 52 A second ventilation hole 55 is formed, an LED light source 54 is fixedly installed in the middle of one side of the light board 52 away from the heat sink 53, and the LED light source 54 is located inside the second mounting groove 12. A ventilation pipe 16 is fixedly connected to the middle of one side of the translucent lampshade 1 close to the cooling shell 4, and the ventilation pipe 16 is communicated with the inside of the translucent lampshade 1. One end of the ventilation pipe 16 away from the translucent lampshade 1 is communicated with the inside of the car, and two spotlight covers 14 corresponding to the LED light source 54 are fixedly installed inside the translucent lampshade 1, and a lens 15 is installed at the end of the spotlight cover 14, and the LED light source 54 is located inside the spotlight cover 14.

[0036] Because of the wind collecting scoop 21 and the triangular guide block 23, the flow velocity of the airflow when entering the cooling shell 4 is relatively large, and the pressure decreases when the flow velocity is large. Therefore, when the high-speed airflow passes through the cooling shell 4, the hot air inside the light-transmitting lampshade 1 will be sucked along with the first ventilation hole 13 and the second ventilation hole 55, and then be taken away by the high-speed airflow. In order to maintain pressure balance, the light-transmitting lampshade 1 will draw air from the inside of the car through the ventilation pipe 16, and then complete the cooling of the inside of the light-transmitting lampshade 1. Drawing air from the inside of the car can reduce the possibility of dust and other debris entering the light-transmitting lampshade 1. When cooling the lighting component 5, the inside of the light-transmitting lampshade 1 can also be cooled. If you do not want to cool the inside of the light-transmitting lampshade 1, you only need to rotate the lighting component 5 so that the second ventilation hole 55 and the first ventilation hole 13 are staggered. At this time, the gas inside the light-transmitting lampshade 1 cannot be sucked. At this time, the ventilation pipe 16 can also play a protective role to prevent the temperature of the light-transmitting lampshade 1 from rising and causing the light-transmitting lampshade 1 to be broken by air pressure. The ventilation pipe 16 can eliminate the pressure generated by thermal expansion and contraction of the air.

[0037] The LED light source 54 is used to provide lighting. When used for a long time, the lamp board 52 will heat up quickly. Therefore, a heat sink 53 is provided to allow heat to be quickly transferred to the heat sink 53. When air flows through, the heat on the heat sink 53 can be quickly taken away, thereby cooling the lamp board 52 to prevent the lamp board 52 from burning out due to long-term use. Because the LED light source 54 uses LED lamp beads, LED lamps can operate stably without filling inert gas during use. They are more stable than halogen headlights. However, the main board of the LED lamp is prone to overheating during use. If the main board is in an overheated state for a long time, the service life of the LED lamp will be greatly shortened, and even damage will be caused. Therefore, cooling of the LED headlight during use is extremely important.

[0038] A recovery component 6 is installed inside the cooling shell 4. The recovery component 6 is located below the fixed shell 41. The recovery component 6 includes a battery 61, an induction switch 62, a first diode 63, a second diode 64, a master control switch 65, a voltage regulator 66, and a fan 67. The battery 61 is connected in series with the master control switch 65 and the fan 67, the voltage regulator 66 is connected in series with the second diode 64, the induction switch 62 is connected in series with the first diode 63, and the induction switch 62, the first diode 63, the voltage regulator 66, and the second diode 64 are connected in parallel.

[0039] When the user turns on the headlights, the master switch 65 is closed, and the battery 61, the fan 67, and the induction switch 62 form a closed loop. Because of the voltage stabilizer 66, the voltage stabilizer 66 does not work at this time. The induction switch 62 can detect the state of the vehicle in real time. When the vehicle is in motion and the lights are on, the induction switch 62 is disconnected, and the air flow passes through the air inlet housing 2, the cooling housing 4, and the air outlet housing 3. When the air flow passes through the cooling housing 4, the fan 67 is driven by the air flow to rotate. Because of the second diode 64, the battery 61 cannot supply current to the fan 67 at this time, and the fan 67 will generate when it is blown. The current can pass through the second diode 64 and the voltage stabilizer 66 in one direction and charge the battery 61. The voltage stabilizer 66 can stabilize the voltage to prevent the rotation speed change of the fan 67 from causing voltage instability and causing damage to the battery 61. The second diode 64 and the first diode 63 only allow the current to pass through in one direction. When the vehicle is stopped and the headlights are turned on, the induction switch 62 is closed. At this time, the battery 61 outputs current to the outside. The current passes through the induction switch 62 and the first diode 63 and passes through the fan 67. The fan 67 will work and rotate, thereby actively driving the air flow inside the cooling shell 4 to prevent the headlights from being damaged due to the car turning on the headlights in situ.

[0040] Therefore, the device is provided with a recovery component 6. When the car is driving, the fan 67 can be driven to recover kinetic energy, thereby charging the battery 61. When the car is stationary, the battery 61 will supply the fan 67 with the electricity required for the operation. The working mode can be changed according to the driving state of the car. The kinetic energy generated by the airflow can be converted and collected when driving, and active cooling protection can be generated when stopping to ensure working stability.

[0041] Mounting rods 17 are fixedly mounted at both ends of one side of the light-transmitting lampshade 1 close to the cooling shell 4 , and the mounting rods 17 are used to mount the device on the lamp mounting position of the vehicle.

[0042] Working principle: In actual use, when the vehicle is driving, the air inlet shell 2 can collect and transport the airflow to the inside of the cooling shell 4, and then finally pass through the cooling shell 4 into the inside of the air outlet shell 3. The airflow entering the air inlet shell 2 is accelerated because of the reduced cross-section, and the air inlet shell 2 can further guide the airflow into the inside of the cooling shell 4, and the triangular guide block 23 gradually reduces the cross-section inside the air inlet shell 2, so the airflow entering the cooling shell 4 will be further accelerated, the lighting component 5 can provide lighting, and the airflow passing through the lighting component 5 can cool the lighting component 5, and one end of the air outlet shell 3 has an inclined plate 31, so during driving, the airflow will be pushed away by the inclined plate 31, so that the airflow velocity on one side of the inclined plate 31 is larger, and then the air pressure at the position of the inclined plate 31 is reduced, and then the air inside the air outlet shell 3 will be sucked out through the air outlet 32;

[0043] Because of the wind collecting scoop 21 and the triangular guide block 23, the airflow enters the cooling housing 4 at a relatively high velocity. Therefore, when the high-speed airflow passes through the cooling housing 4, the hot air inside the light-transmitting lampshade 1 is sucked along the first ventilation hole 13 and the second ventilation hole 55, and then carried away by the high-speed airflow. The light-transmitting lampshade 1 absorbs air from the interior of the vehicle through the ventilation pipe 16, thereby completing the cooling of the interior of the light-transmitting lampshade 1.

[0044] When the user turns on the headlights, the master control switch 65 is closed, and the battery 61, the fan 67, and the induction switch 62 form a closed loop. Because of the voltage stabilizer 66, the voltage stabilizer 66 does not work at this time, and the induction switch 62 can detect the state of the vehicle in real time. When the vehicle is in motion and the lights are on, the induction switch 62 is disconnected, and the air flow passes through the air inlet housing 2, the cooling housing 4, and the air outlet housing 3. When the air flow passes through the cooling housing 4, the fan 67 is driven by the air flow to rotate. Because of the second diode 64, the battery 61 cannot supply current to the fan 67 at this time, and the fan 67 is When blowing, current will be generated, and the current can unidirectionally pass through the second diode 64 and the voltage stabilizer 66 to charge the battery 61. The voltage stabilizer 66 can stabilize the voltage to prevent the speed change of the fan 67 from causing voltage instability and causing damage to the battery 61. The second diode 64 and the first diode 63 only allow current to pass through in one direction. When the vehicle is in a stopped state and the headlights are on, the induction switch 62 is closed. At this time, the battery 61 outputs current to the outside, and the current passes through the induction switch 62 and the first diode 63 and passes through the fan 67. The fan 67 will work and rotate, thereby actively driving the air flow inside the cooling shell 4.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
