Description

Technical Field

[0001] The present application relates to the technical field of lens modules, and in particular to an LED lens module, a lamp and a vehicle. Background Art

[0002] With the rapid development of the automotive industry, vehicle lighting is gradually shifting towards automation and intelligence.

[0003] In the related art, the LED lens module and PCB controller in the vehicle-mounted lamp are two independent components, among which the PCB controller is used to control the operation of the LED component in the LED lens module, and is mainly used to control the high and low beam switching of the LED lamp (the light-emitting element in the LED component). It should be noted that the LED lamp will emit a lot of heat during operation, and the PCB controller is usually composed of a variety of high-heat generating components such as chips, inductors, MOS tubes, etc., so it is necessary to dissipate heat for the PCB controller and the LED lens module in time. However, the utilization rate of the heat sinks corresponding to the LED lens module and the PCB controller is not high at present, resulting in low heat dissipation efficiency. Summary of the invention

[0004] The present application provides an LED lens module, a lamp and a vehicle, which solve the current technical problem that the utilization rate of the heat sinks corresponding to the LED lens module and the PCB controller is low. By integrating the LED component and the PCB controller on the substrate of the same heat sink, it is beneficial to improve the utilization rate of the heat sink, thereby improving the heat dissipation efficiency, and further improving the performance of the LED lens module.

[0005] In order to achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, an embodiment of the present application provides an LED lens module, comprising:

[0007] case;

[0008] A lens body, wherein the lens body is fixed to the housing;

[0009] A heat sink, the heat sink is fixed to the housing, the heat sink includes a substrate, along a first direction, the lens body and the substrate are arranged opposite to each other and are spaced apart, the housing, the lens body and the substrate jointly form a mounting cavity, the substrate has a first mounting portion and a second mounting portion on a side close to the lens body, along a second direction, the first mounting portion and the second mounting portion are arranged in sequence, wherein the first direction is perpendicular to the second direction;

[0010] The LED component and the PCB controller are both arranged in the installation cavity. The LED component is fixed on the first installation part and is arranged opposite to the lens body. The PCB controller is fixed on the second installation part.

[0011] The LED lens module proposed in the first aspect of the embodiment of the present application integrates the LED component and the PCB controller on the substrate of the same radiator, which is beneficial to improving the utilization rate of the radiator, thereby improving the heat dissipation efficiency, and further improving the performance of the LED lens module; at the same time, compared with the traditional practice of setting the PCB controller in the lamp housing and causing poor sealing, the present application integrates the PCB controller inside the LED lens module, which is beneficial to improving the sealing of the PCB controller and preventing defects such as water ingress into the PCB controller.

[0012] Optionally, along the second direction, the LED assembly and the PCB controller are spaced apart.

[0013] Such an arrangement can further reduce the heat transfer between the LED component and the PCB controller, and prevent the high heat generated by the LED component from having a significant impact on the PCB controller, thereby affecting the normal operation of the PCB controller.

[0014] Optionally, the spacing distance between the LED component and the PCB controller is d, satisfying the relationship: d≥3mm.

[0015] Such an arrangement can ensure the spacing between the LED component and the PCB controller in the second direction, further reduce the impact of high heat generated by the LED component on the PCB controller, and help ensure the normal operation of the PCB controller.

[0016] Optionally, along the first direction, the first mounting portion protrudes in a direction away from the second mounting portion, and the first mounting portion is connected to the second mounting portion to form a first step surface.

[0017] Such an arrangement makes the thickness of the substrate where the PCB controller is installed smaller than the thickness of the substrate where the LED component is installed. It can be understood that the thermal resistance of the thinner area of ​​the substrate is smaller, so the heat transferred outward from the PCB controller through the substrate can be accelerated, which is beneficial to improving the heat dissipation efficiency of the PCB controller, thereby ensuring the normal operation of the PCB controller.

[0018] Optionally, along the first direction, the size of the first step surface is h, satisfying the relationship: d≥2mm.

[0019] Such an arrangement can ensure the spacing between the LED component and the PCB controller in the first direction, further reduce the influence of the high heat generated by the LED component on the PCB controller, and help ensure the normal operation of the PCB controller.

[0020] Optionally, the heat sink further includes a heat dissipation plate connected to the substrate, and the heat dissipation plate is arranged on a side of the substrate away from the lens body.

[0021] Such an arrangement greatly improves the heat dissipation efficiency of the radiator, which is beneficial to further improving the performance of the LED lens module.

[0022] Optionally, the heat dissipation plate protrudes along the first direction toward a direction away from the substrate and extends along the second direction.

[0023] Such a configuration makes the extension direction of the heat sink consistent with the movement direction of the hot air, which facilitates the cold air to flow in from the bottom of the heat sink and take away the heat of the heat sink, and finally dissipate the hot air after heat exchange from the top of the heat sink. It can also prevent the hot air from flowing back to the second mounting area of ​​the substrate, thereby avoiding adverse effects on the heat dissipation of the PCB controller.

[0024] Optionally, there are multiple heat dissipation plates, and the multiple heat dissipation plates are arranged in sequence and at intervals along a third direction, wherein the third direction is perpendicular to both the first direction and the second direction.

[0025] Such a configuration helps to increase the contact area between the radiator and the external cold air by setting up multiple heat sinks, so that the heat on the substrate can be dissipated to the outside through multiple heat sinks at the same time, which can further quickly dissipate the heat to the external environment, further improving the heat dissipation efficiency of the radiator.

[0026] Optionally, along the first direction, the heat sink has a first end and a second end that are relatively set, and along the third direction, the heat sink has a first end face and a second end face that are relatively set, the first end is fixedly connected to the substrate, and the distance between the first end face and the second end face gradually decreases from the first end to the second end, wherein the third direction is perpendicular to both the first direction and the second direction.

[0027] Therefore, by setting the heat sink as a whole to a trapezoidal structure that is thick at the bottom and thin at the top, it is beneficial to reduce the thermal resistance of the heat sink, thereby improving the heat transfer efficiency of the heat sink, and it is also beneficial to reduce the weight of the heat sink, thereby achieving a perfect combination of the heat dissipation efficiency and lightweight design of the heat sink, that is, reducing the thermal resistance between the heat sink and the substrate while ensuring the optimal weight of the entire radiator, thereby accelerating the heat conduction speed.

[0028] Optionally, the first end surface and the second end surface both have a plurality of heat dissipation grooves, the plurality of heat dissipation grooves all extend along the second direction, and each heat dissipation groove is recessed inwardly toward the heat dissipation plate.

[0029] Such a configuration can effectively increase the area of ​​the heat sink without affecting the heat convection heat exchange between the heat sink and the cold air, thereby effectively increasing the heat radiation and heat convection heat exchange of the radiator to quickly dissipate the heat on the radiator to the external environment.

[0030] Optionally, it further comprises: a condenser, which is arranged in the installation cavity, and along the first direction, the condenser is arranged between the lens body and the LED assembly, and the condenser and the LED assembly are arranged opposite to each other and spaced apart;

[0031] Along the second direction, the shell has a first side wall, which is closer to the LED assembly than the PCB controller, and the first side wall is provided with a first ventilation hole connected to the mounting cavity, the lens body is projected toward the first side wall along the second direction to form a first lens projection, and the concentrator is projected toward the first side wall along the second direction to form a first concentrator projection, and along the first direction, the first ventilation hole is provided between the first lens projection and the first concentrator projection.

[0032] Such a configuration can quickly dissipate the heat dissipated into the interior of the LED lens module through the concentrator, thereby avoiding heat accumulation in the LED lens module. Moreover, since the first ventilation hole is arranged on the upper side of the shell, that is, the first ventilation hole is arranged in the flow direction of the hot air, it is beneficial to increase the flow rate of the hot air and further accelerate the dissipation of heat from the first ventilation hole.

[0033] Optionally, along the second direction, the shell also has a second side wall arranged opposite to the first side wall, the second side wall is closer to the PCB controller relative to the LED assembly, the second side wall is provided with a second ventilation hole arranged corresponding to the first ventilation hole, and the second ventilation hole is connected to the installation cavity.

[0034] With such a configuration, cold air from the outside enters the interior of the LED lens module from the second ventilation hole at the bottom, and hot air flows out from the first ventilation hole above the LED lens module. With the continuous entry of cold air and the continuous discharge of hot air to take away the heat accumulated inside the LED lens module, it can be understood that the configuration of the first ventilation hole and the second ventilation hole increases the convection speed of cold and hot air, which is conducive to further increasing the flow rate of hot air, thereby further accelerating the dissipation of heat from the first ventilation hole.

[0035] Optionally, the first side wall is provided with a third ventilation hole connected to the mounting cavity, at least part of the direct projection of the concentrator along the second direction toward the first side wall overlaps with the third ventilation hole, and at least part of the direct projection of the LED component along the second direction toward the first side wall overlaps with the third ventilation hole.

[0036] Such an arrangement ensures that the gap between the LED assembly and the concentrator can be opposite to the third ventilation hole, so that the heat accumulated between the LED assembly and the concentrator can be dissipated through the third ventilation hole, avoiding excessive accumulation of heat between the LED assembly and the concentrator, which is beneficial to reducing the ambient temperature of the LED assembly.

[0037] Optionally, the second side wall is provided with a fourth ventilation hole corresponding to the third ventilation hole, and the fourth ventilation hole is connected to the installation cavity. In this arrangement, cold air from the outside enters between the LED component and the concentrator from the fourth ventilation hole below, and hot air flows out from the third ventilation hole above the LED lens module. With the continuous entry of cold air and the continuous discharge of hot air to take away the heat accumulated between the LED component and the concentrator, it can be understood that the arrangement of the third ventilation hole and the fourth ventilation hole increases the convection speed of cold and hot air, which is conducive to further increasing the flow rate of hot air, thereby further accelerating the heat dissipation from the third ventilation hole, which is conducive to further reducing the ambient temperature of the LED component.

[0038] Optionally, along the second direction, the concentrator has a third end face and a fourth end face arranged at intervals on one side close to the LED assembly, the third end face is provided with a plurality of first ventilation slots, each of the first ventilation slots is recessed inwardly toward the concentrator and extends along the second direction, and the plurality of first ventilation slots are sequentially arranged at intervals along the third direction;

[0039] The fourth end surface is provided with a plurality of second ventilation slots, each of which is recessed inwardly toward the concentrator and extends along the second direction, and the plurality of second ventilation slots are sequentially arranged at intervals along the third direction.

[0040] With such an arrangement, part of the cold air can enter between the LED assembly and the concentrator from the second ventilation slot, and part of the hot air after heat exchange can also flow out from between the LED assembly and the concentrator through the first ventilation slot. That is to say, the arrangement of the first ventilation slot and the second ventilation slot accelerates the flow of hot air between the LED assembly and the concentrator, and can take away the hot air between the LED assembly and the concentrator more quickly, thereby effectively reducing the temperature between the LED assembly and the concentrator, and finally quickly dissipating the heat at the LED assembly into the environment.

[0041] In a second aspect, an embodiment of the present application provides a lamp, comprising the LED lens module in the embodiment of the first aspect.

[0042] The lamp proposed in the second aspect of the embodiment of the present application is provided with the above-mentioned LED lens module, and the LED component and the PCB controller are integrated on the substrate of the same radiator, which is beneficial to improve the utilization rate of the radiator, thereby improving the heat dissipation efficiency, and further improving the performance of the LED lens module; at the same time, compared with the traditional poor sealing phenomenon caused by setting the PCB controller in the lamp housing, the present application integrates the PCB controller inside the LED lens module, which is beneficial to improve the sealing of the PCB controller and prevent defects such as water ingress into the PCB controller.

[0043] In a third aspect, an embodiment of the present application provides a vehicle, comprising the lamp in the embodiment of the second aspect.

[0044] The vehicle proposed in the third aspect of the embodiment of the present application is provided with the above-mentioned lamp, and the LED component and the PCB controller are integrated on the substrate of the same radiator, which is beneficial to improve the utilization rate of the radiator, thereby improving the heat dissipation efficiency, and further improving the performance of the LED lens module; at the same time, compared with the traditional phenomenon of poor sealing caused by setting the PCB controller in the lamp housing, the present application integrates the PCB controller inside the LED lens module, which is beneficial to improve the sealing of the PCB controller and prevent defects such as water ingress into the PCB controller.

[0069] With the rapid development of the automotive industry, car lights are gradually shifting towards automation and intelligence, so people have also put forward higher requirements on the performance of car lights.

[0070] In the related art, the LED lens module and PCB controller in the car light are two independent components. Among them, the PCB controller is used to control the operation of the LED component in the LED lens module, and is mainly used to control the high and low beam switching of the LED lamp (the light-emitting element in the LED component). It should be noted that the LED lamp will emit a lot of heat during operation, and the PCB controller is usually composed of a variety of high-heat generating components such as chips, inductors, MOS tubes, etc., so it is necessary to dissipate heat for the PCB controller and the LED lens module in time.

[0071] However, currently the PCB controller is usually fixed to the housing of the lamp by screws, which may easily lead to problems such as poor sealing and water ingress of the PCB controller. In addition, the LED lens module is arranged in the lamp, and the PCB controller and the LED lens module each have their own separate heat sinks. Therefore, the utilization rate of the heat sinks corresponding to the PCB controller and the LED lens module is not high, resulting in low heat dissipation efficiency, which in turn affects the performance of the car lamp.

[0072] Based on this, the present application proposes an LED lens module 100, in which the LED component 4 and the PCB controller 5 are integrated on the substrate 31 of the same heat sink 3, which is beneficial to improving the utilization rate of the heat sink 3, thereby improving the heat dissipation efficiency, and further improving the performance of the LED lens module 100; at the same time, compared with the traditional poor sealing phenomenon caused by setting the PCB controller in the lamp housing, the present application integrates the PCB controller 5 inside the LED lens module 100, which is beneficial to improving the sealing of the PCB controller 5 and preventing defects such as water ingress into the PCB controller 5.

[0073] The LED lens module 100, lamp and vehicle proposed in the embodiments of the present application are described below with reference to the accompanying drawings.

[0074] like Figure 1-Figure 8 As shown, the LED lens module 100 according to the first embodiment of the present application includes: a shell 1, a lens body 2, a heat sink 3, an LED component 4 and a PCB controller 5, the lens body 2 is fixed to the shell 1, the heat sink 3 is fixed to the shell 1, the heat sink 3 includes a substrate 31, along the first direction X, the lens body 2 and the substrate 31 are arranged opposite to each other and spaced apart, the shell 1, the lens body 2 and the substrate 31 jointly form an installation cavity, the substrate 31 has a first installation portion 311 and a second installation portion 312 on a side close to the lens body 2, along the second direction Y, the first installation portion 311 and the second installation portion 312 are arranged in sequence, wherein the first direction X is perpendicular to the second direction Y, the LED component 4 and the PCB controller 5 are both arranged in the installation cavity, the LED component 4 is fixed to the first installation portion 311 and is arranged opposite to the lens body 2, and the PCB controller 5 is fixed to the second installation portion 312.

[0075] Specifically, Figure 3 The placement direction of the LED lens module 100 shown is taken as an example for explanation, wherein the first direction X is the horizontal direction, the LED lens module 100 is placed horizontally, the second direction Y is the height direction, and the first mounting portion 311 and the second mounting portion 312 of the substrate 31 are arranged along the height direction. It should be noted that the LED component 4 is fixedly mounted on the first mounting portion 311 and because the LED component 4 generates a large amount of heat when in contact with the substrate 31, in order to reduce the heat transfer between the LED component 4 and the PCB controller 5 and avoid the heat generated by the high-heat LED component 4 from being transferred to the PCB controller 5 board, according to the thermodynamic transfer mechanism of heat transfer from high-temperature medium to low-temperature medium and heat transfer upward along the direction of gravity, the LED component 4 needs to be set above the PCB controller 5. Therefore, during the installation and placement process of the LED lens module 100 of the present application, it is necessary to ensure that the first mounting portion 311 of the substrate 31 is located above the second mounting portion 312.

[0076] like Figure 1 and Figure 2As shown, the shell 1 is overall constructed as a columnar structure formed by connecting multiple side walls in sequence, and has a first opening and a second opening that are connected along the first direction X of the shell 1, wherein the lens body 2 is fixedly mounted on the shell 1 and is used to block the first opening, and along the first direction X, the substrate 31 of the heat sink 3 is arranged opposite to and spaced from the lens body 2, and the substrate 31 is also fixedly mounted on the shell 1 and is used to block the second opening, with such an arrangement, the inner side wall of the shell 1 and the inner surfaces relative to the lens body 2 and the substrate 31 jointly form a mounting cavity.

[0077] Furthermore, the LED component 4 and the PCB controller 5 are both arranged in the installation cavity, and the LED component 4 is connected to the PCB controller 5 for communication. For example, the LED component 4 includes an LED lamp and an LED lamp board. The LED lamp is fixedly installed on the LED lamp board. The LED lamp board is fixedly installed on the first installation portion 311 of the substrate 31, and ensures that the LED lamp is arranged relative to the lens body 2. A data line is arranged in the LED lamp board. The LED lamp is connected to the PCB controller 5 for communication through the data line in the LED lamp board. The PCB controller 5 is used to control the high and low beam switching of the LED lamp. It can be understood that during the light emission of the LED lamp, part of the light directly irradiates the lens body opposite to the LED lamp. 2, and then emitted to the outside of the LED lens module 100 through the lens body 2, and part of the light is emitted outward in the form of heat radiation, wherein the outwardly emitted heat radiation part is transferred to the substrate 31 of the radiator 3 through the LED lamp board, and finally the heat dissipation of the LED component 4 is realized through the radiator 3; at the same time, the PCB controller 5 is directly mounted on the second mounting portion 312 of the substrate 31. In the process of controlling the light emission of the LED lamp, the high-heat-generating components such as the chip, inductor, MOS tube in the PCB controller 5 will also emit a large amount of heat. Therefore, the heat generated by the PCB controller 5 can be directly transferred to the substrate 31 of the radiator 3, and finally the heat dissipation of the PCB controller 5 is realized through the radiator 3.

[0078] With such a configuration, compared with the problem of low utilization rate of the heat sink 3 caused by the traditional PCB controller 5 and the LED lens module 100 each having a separate heat sink 3, the present application integrates the LED component 4 and the PCB controller 5 on the substrate 31 of the same heat sink 3, which is beneficial to improving the utilization rate of the heat sink 3, thereby improving the heat dissipation efficiency, and further improving the performance of the LED lens module 100.

[0079] The present application integrates the PCB controller 5 inside the LED lens module 100. Compared with the traditional PCB controller 5 which is usually fixed to the housing of the lamp by screws, the sealing of the PCB controller 5 is improved, which is beneficial to prevent defects such as water ingress to the PCB controller 5.

[0080] To sum up, the LED lens module 100 proposed in the embodiment of the first aspect of the present application integrates the LED component 4 and the PCB controller 5 on the substrate 31 of the same heat sink 3, which is beneficial to improve the utilization rate of the heat sink 3, thereby improving the heat dissipation efficiency, and further improving the performance of the LED lens module 100; at the same time, compared with the traditional poor sealing phenomenon caused by setting the PCB controller in the lamp housing, the present application integrates the PCB controller 5 inside the LED lens module 100, which is beneficial to improve the sealing of the PCB controller 5 and prevent defects such as water ingress into the PCB controller 5.

[0081] In some embodiments of the present application, Figure 3 As shown, the LED assembly 4 and the PCB controller 5 are spaced apart along the second direction Y. That is, in order to further reduce the mutual influence and transfer of heat between the LED assembly 4 and the PCB controller 5, the LED assembly 4 and the PCB controller 5 in the present application have a certain spacing distance along the second direction Y (i.e., the height direction of the LED lens module 100), thereby further reducing the heat transfer between the LED assembly 4 and the PCB controller 5, and avoiding the high heat generated by the LED assembly 4 from having a greater impact on the PCB controller 5, thereby affecting the normal operation of the PCB controller 5.

[0082] In some embodiments of the present application, the spacing distance between the LED component 4 and the PCB controller 5 is d, which satisfies the relationship: d≥3mm. That is to say, in the present application, the spacing distance between the LED component 4 and the PCB controller 5 along the second direction Y is generally set to be greater than or equal to 3mm. For example, the spacing distance between the LED component 4 and the PCB controller 5 in the second direction Y can be 3mm, 4mm, 5mm, or 6mm, which is set according to actual conditions and is not specifically limited here. Such a setting can ensure the spacing between the LED component 4 and the PCB controller 5 in the second direction Y, further reduce the influence of the high heat generated by the LED component 4 on the PCB controller 5, and is conducive to ensuring the normal operation of the PCB controller 5.

[0083] In some embodiments of the present application, Figure 5 and Figure 6 As shown, along the first direction X, the first mounting portion 311 protrudes in a direction away from the second mounting portion 312 , and the first mounting portion 311 is connected to the second mounting portion 312 to form a first step surface.

[0084] Specifically, the side of the substrate 31 close to the lens body 2 is the inner surface, and the side of the substrate 31 away from the lens body 2 is the outer surface, and the inner surface of the substrate 31 is provided with a first mounting portion 311 and a second mounting portion 312 in sequence along the second direction Y, wherein the first mounting portion 311 is provided above the second mounting portion 312, the first mounting portion 311 protrudes in a direction away from the second mounting portion 312, and the first mounting portion 311 is connected to the second mounting portion 312 to form a first step surface, that is, the first mounting portion 311 protrudes relative to the second mounting portion 312 in a direction away from the substrate 31, and a first step surface is formed at the connection between the first mounting portion 311 and the second mounting portion 312.

[0085] For example, the first mounting portion 311 can be configured as a first mounting surface, the second mounting portion 312 can be configured as a second mounting surface, the LED component 4 is fixedly mounted on the first mounting surface, and the PCB controller 5 is fixedly mounted on the second mounting surface. In some embodiments of the present application, the contact area between the LED component 4 and the first mounting surface is relatively large, for example, the contact area between the LED component 4 and the first mounting surface is 3325mm 2 , and the first step surface is usually smaller in area, for example, the area of ​​the first step surface is 280mm 2 Therefore, most of the heat generated by the LED component 4 is preferentially transferred outward through the substrate 31 for heat dissipation, and only a small part of the heat will affect the PCB controller 5 fixedly mounted on the second mounting surface, thereby further reducing the impact of the high heat generated by the LED component 4 on the PCB controller 5, which is beneficial to further ensure the normal operation of the PCB controller 5.

[0086] It should be noted that, in some embodiments of the present application, the outer surface of the substrate 31 can be constructed as a plane. In this way, the thickness of the substrate 31 in the first mounting portion 311 area is greater than the thickness of the substrate 31 in the second mounting portion 312 area. In this way, the thickness of the substrate 31 where the PCB controller 5 is installed is less than the thickness of the substrate 31 where the LED component 4 is installed. It can be understood that the thermal resistance of the thinner area of ​​the substrate 31 is smaller, so the heat transferred to the outside by the PCB controller 5 through the substrate 31 can be accelerated, which is beneficial to improving the heat dissipation efficiency of the PCB controller 5, thereby ensuring the normal operation of the PCB controller 5.

[0087] In some embodiments of the present application, along the first direction X, the size of the first step surface is h, satisfying the relationship: d ≥ 2mm. That is to say, the size of the first step surface formed along the first direction X at the connection between the first mounting portion 311 and the second mounting portion 312 in the present application is greater than or equal to 2mm. For example, the size of the first step surface formed along the first direction X at the connection between the first mounting portion 311 and the second mounting portion 312 can be 2mm, 3mm, 4mm, 5mm, 6mm, which is set according to actual conditions and is not specifically limited here. Such a setting can ensure the spacing between the LED component 4 and the PCB controller 5 in the first direction X, further reduce the influence of the high heat generated by the LED component 4 on the PCB controller 5, and is conducive to ensuring the normal operation of the PCB controller 5.

[0088] In some embodiments of the present application, Figure 1-Figure 7 As shown, the heat sink 3 further includes a heat dissipation plate 32 connected to the substrate 31 , and the heat dissipation plate 32 is arranged on a side of the substrate 31 away from the lens body 2 .

[0089] Specifically, a heat sink 32 is further provided on the outer surface of the substrate 31. Optionally, the heat sink 32 can be constructed as an arc-shaped plate, a circular plate, an annular plate, etc., and is specifically set according to actual cooling requirements. No specific restrictions are made here. The heat sink 32 can increase the contact area between the radiator 3 and the external cold air. When the heat generated by the LED component 4 and the PCB controller 5 is transferred to the substrate 31 of the radiator 3, the heat on the substrate 31 can be quickly conducted to the heat sink 32 outside the substrate 31, and then the surface of the heat sink 32 is used to exchange heat with the external cold air through heat radiation and heat convection, thereby quickly dissipating the heat to the external environment. Such a setting greatly improves the heat dissipation efficiency of the radiator 3, which is beneficial to further improve the performance of the LED lens module 100.

[0090] In some embodiments of the present application, Figure 1-Figure 4As shown, the heat dissipation plate 32 protrudes along the first direction X in a direction away from the substrate 31 and extends along the second direction Y. That is to say, the heat sink 32 is arranged on the outer surface of the substrate 31 and protrudes in the direction away from the substrate 31 along the first direction X. For example, the heat sink 32 can be perpendicular to the outer surface of the substrate 31, or it can be constructed to have a certain angle with the substrate 31. Further, the heat sink 32 also extends along the second direction Y, that is, the extension direction of the heat sink 32 is consistent with the arrangement direction of the first mounting portion 311 and the second mounting portion 312. According to the thermodynamic transfer mechanism, hot air moves upward in the height direction. The placement of the LED lens module 100 in this application ensures that the first mounting portion 311 for mounting the LED component 4 is located above the second mounting portion 312 for mounting the PCB controller 5. In this way, the extension direction of the heat sink 32 is consistent with the movement direction of the hot air, which facilitates the cold air to flow into and take away the heat of the heat sink 32 from the bottom of the heat sink 32, and finally dissipate the hot air after heat exchange from the top of the heat sink 32, and can also prevent the hot air from flowing back to the second mounting portion 312 area of ​​the substrate 31, thereby avoiding adverse effects on the heat dissipation of the PCB controller 5.

[0091] In some embodiments of the present application, Figure 5 and Figure 7 As shown, there are multiple heat sinks 32, and the multiple heat sinks 32 are arranged in sequence along the third direction Z, wherein the third direction Z is perpendicular to both the first direction X and the second direction Y. That is to say, multiple heat sinks 32 arranged at intervals can be arranged on the outer surface of the substrate 31 along the third direction Z. Optionally, each heat sink 32 protrudes along the first direction X in a direction away from the substrate 31 and extends along the second direction Y. It can be understood that the multiple heat sinks 32 can be arranged at uniform intervals or at non-uniform intervals along the third direction Z, depending on the actual situation, and no specific restrictions are made here. In this way, by setting up multiple heat sinks 32, it is beneficial to increase the contact area between the radiator 3 and the external cold air, so that the heat on the substrate 31 can be dissipated to the outside world through the multiple heat sinks 32 at the same time, which can further quickly dissipate the heat to the external environment, further improving the heat dissipation efficiency of the radiator 3.

[0092] In some embodiments of the present application, Figure 7 As shown, along the first direction X, the heat sink 32 has a first end 321 and a second end 322 that are relatively set, and along the third direction Z, the heat sink 32 has a first end 321 surface and a second end 322 surface that are relatively set, the first end 321 is fixedly connected to the substrate 31, and from the first end 321 to the second end 322, the distance between the first end 321 surface and the second end 322 surface gradually decreases, wherein the third direction Z is perpendicular to both the first direction X and the second direction Y.

[0093] Specifically, the first end 321 of the heat sink 32 is fixedly connected to the outer surface of the substrate 31, and the second end 322 of the heat sink 32 extends along the first direction X in a direction away from the substrate 31, and along the third direction Z, the heat sink 32 has a first end 321 surface and a second end 322 surface that are oppositely arranged, and the distance between the first end 321 surface and the second end 322 surface gradually decreases from the first end 321 to the second end 322. That is, assuming that the first direction X and the third direction Z form a cutting surface, the heat sink After the cutting surface 32 is cut, when the cutting surface of the heat sink 32 is viewed from the second direction Y, the cutting surface of the heat sink 32 is generally in a trapezoidal structure, and from the first end 321 to the second end 322, the bottom dimension of the trapezoid along the third direction Z at the first end 321 is larger than the outer dimension of the trapezoid along the third direction Z at the second end 322. For example, the bottom dimension is 2.5 mm, and the outer dimension is 1.25 mm. Along the first direction X, the spacing distance between the first end 321 and the second end 322 is 45 mm.

[0094] Based on the thermal balance mechanism of conduction and heat dissipation in thermodynamics, and the fact that heat is continuously dissipated outward through thermal radiation and thermal convection during the transfer process, the heat transfer on the heat sink 32 is continuously reduced. Therefore, by setting the heat sink 32 as a trapezoidal structure with a thick bottom and a thin top, it is beneficial to reduce the thermal resistance of the heat sink 32, thereby improving the heat transfer efficiency of the heat sink 32, and at the same time, it is also beneficial to reduce the weight of the heat sink 32, thereby achieving a perfect combination of the heat dissipation efficiency and lightweight design of the heat sink 32, that is, reducing the thermal resistance between the heat sink 32 and the substrate 31 while ensuring the optimal weight of the entire radiator 3, thereby accelerating the heat conduction speed.

[0095] In some embodiments of the present application, Figure 7 As shown, the first end 321 surface and the second end 322 surface are both provided with a plurality of heat dissipation slots 323, and the plurality of heat dissipation slots 323 are both extended along the second direction Y, and each heat dissipation slot 323 is recessed inwardly toward the direction of the heat dissipation plate 32. That is to say, the first end 321 surface and the second end 322 surface of each heat dissipation plate 32 are both provided with a heat dissipation slot 323 extending along the second direction Y, and the heat dissipation slots 323 on the first end 321 surface and the second end 322 surface can be provided in plurality. For example, the plurality of heat dissipation slots 323 on the first end 321 surface are sequentially provided from the first end 321 to the second end 322, and similarly, the plurality of heat dissipation slots 323 on the second end 322 surface are also sequentially provided from the first end 321 to the second end 322, and the extension direction of the heat dissipation slots 323 is consistent with the extension direction of the heat dissipation plate 32, and both extend along the flow direction of the hot air. Such a configuration can effectively increase the area of ​​the heat sink 32 without affecting the heat convection heat exchange between the heat sink 32 and the cold air, thereby effectively increasing the heat of the heat radiation and heat convection heat exchange of the radiator 3 to quickly dissipate the heat on the radiator 3 to the external environment.

[0096] In some embodiments of the present application, Figure 3 , Figure 4 and Figure 8 As shown, it also includes: a concentrator 6, which is arranged in the installation cavity. Along the first direction X, the concentrator 6 is arranged between the lens body 2 and the LED component 4, and the concentrator 6 is arranged opposite to and spaced from the LED component 4. Along the second direction Y, the shell 1 has a first side wall 11, and the first side wall 11 is closer to the LED component 4 relative to the PCB controller 5. The first side wall 11 is provided with a first ventilation hole 111 connected to the installation cavity. The lens body 2 is projected toward the first side wall 11 along the second direction Y to form a first lens projection. The concentrator 6 is projected toward the first side wall 11 along the second direction Y to form a first concentrator 6 projection. Along the first direction X, the first ventilation hole 111 is arranged between the first lens projection and the first concentrator 6 projection.

[0097] Specifically, the concentrator 6 is arranged in the installation cavity. It can be understood that the concentrator 6 can be constructed as a high and low beam concentrator 6. The high and low beam concentrator 6 is arranged between the lens body 2 and the LED component 4 along the first direction X, and the high and low beam concentrator 6 is arranged relative to the LED component 4 and spaced apart, that is, it is ensured that there is a certain gap between the high and low beam concentrator 6 and the LED component 4. When the PCB controller 5 controls the LED lamp in the LED component 4 to switch between high and low beams, the high and low beam concentrator 6 can respectively concentrate the high beam or low beam emitted by the LED lamp, so that the concentrated high beam or low beam is emitted to the outside through the lens body 2.

[0098] It should be noted that a large amount of heat radiation is generated during the light emission process of the LED component 4. After the heat radiation generated by the LED component 4 is dissipated between the concentrator 6 and the LED component 4, part of the heat radiated by the LED component 4 is dissipated into the interior of the LED lens module 100 after passing through the concentrator 6. Based on this, the present application sets a first ventilation hole 111 connected to the mounting cavity on the first side wall 11, wherein the first side wall 11 is closer to the LED component 4 than the PCB controller 5, and continues with Figure 3 The LED lens module 100 shown in FIG. 1 is placed in the direction of the LED lens module 100 as an example. The first side wall 11 is located on the upper side of the housing 1. Figure 4 As shown, the lens body 2 can form a first lens projection by being projected toward the first side wall 11 along the second direction Y, and the concentrator 6 can form a first concentrator 6 projection by being projected toward the first side wall 11 along the second direction Y. Along the first direction X, the first ventilation hole 111 is arranged between the first lens projection and the first concentrator 6 projection, that is, the first ventilation hole 111 is arranged relative to the mounting cavity between the lens body 2 and the concentrator 6.

[0099] Such a configuration can quickly dissipate the heat dissipated into the interior of the LED lens module 100 through the concentrator 6, thereby avoiding heat accumulation in the LED lens module 100. Moreover, since the first ventilation hole 111 is arranged on the upper side of the shell 1, that is, the first ventilation hole 111 is arranged in the flow direction of the hot air, it is beneficial to increase the flow rate of the hot air and further accelerate the dissipation of heat from the first ventilation hole 111.

[0100] In some embodiments of the present application, Figure 2-Figure 4 As shown, along the second direction Y, the shell 1 also has a second side wall 12 arranged opposite to the first side wall 11, the second side wall 12 is closer to the PCB controller 5 relative to the LED component 4, and the second side wall 12 is provided with a second ventilation hole 121 arranged corresponding to the first ventilation hole 111, and the second ventilation hole 121 is connected to the installation cavity.

[0101] Specifically, along the height direction of the LED lens module 100, the housing 1 further has a second side wall 12 arranged opposite to the first side wall 11, wherein the second side wall 12 is closer to the PCB controller 5 relative to the LED assembly 4. Figure 3 The LED lens module 100 shown in FIG. 1 is placed in the direction as an example. The second side wall 12 is located at the lower side of the housing 1. Figure 4 As shown, the second side wall 12 is provided with a second ventilation hole 121 corresponding to the first ventilation hole 111. It can be understood that the second ventilation hole 121 is also arranged relative to the mounting cavity between the lens body 2 and the concentrator 6. In this arrangement, the cold air from the outside enters the interior of the LED lens module 100 from the second ventilation hole 121 below, and the hot air flows out from the first ventilation hole 111 above the LED lens module 100. With the continuous entry of cold air and the continuous discharge of hot air to take away the heat accumulated inside the LED lens module 100, it can be understood that the arrangement of the first ventilation hole 111 and the second ventilation hole 121 increases the convection speed of cold and hot air, which is conducive to further increasing the flow rate of hot air, thereby further accelerating the heat dissipation from the first ventilation hole 111.

[0102] In some embodiments of the present application, Figure 1 , Figure 3 and Figure 4 As shown, the first side wall 11 is provided with a third ventilation hole 112 connected to the installation cavity, at least part of the positive projection of the concentrator 6 along the second direction Y toward the first side wall 11 overlaps with the third ventilation hole 112, and at least part of the positive projection of the LED component 4 along the second direction Y toward the first side wall 11 overlaps with the third ventilation hole 112.

[0103] Specifically, in order to prevent excessive accumulation of heat radiation generated by the LED component 4 between the LED component 4 and the concentrator 6, a third ventilation hole 112 connected to the mounting cavity is provided on the first side wall 11, wherein at least a portion of the orthographic projection of the concentrator 6 along the second direction Y toward the first side wall 11 overlaps with the third ventilation hole 112, and at least a portion of the orthographic projection of the LED component 4 along the second direction Y toward the first side wall 11 overlaps with the third ventilation hole 112. For example, a portion of the orthographic projection of the concentrator 6 along the second direction Y toward the first side wall 11 overlaps with the third ventilation hole 112, and a portion of the orthographic projection of the LED component 4 along the second direction Y toward the first side wall 11 overlaps with the third ventilation hole 112. Such an arrangement ensures that the gap between the LED component 4 and the concentrator 6 can be opposite to the third ventilation hole 112, so that the heat accumulated between the LED component 4 and the concentrator 6 can be dissipated through the third ventilation hole 112, thereby preventing excessive accumulation of heat between the LED component 4 and the concentrator 6, which is beneficial to reducing the ambient temperature of the LED component 4.

[0104] In some embodiments of the present application, Figure 2-Figure 4 As shown, the second side wall 12 is provided with a fourth ventilation hole 122 corresponding to the third ventilation hole 112, and the fourth ventilation hole 122 is communicated with the installation cavity. That is to say, along the height direction of the LED lens module 100, the second side wall 12 of the housing 1 is provided with a fourth ventilation hole 122 corresponding to the third ventilation hole 112, and the fourth ventilation hole 122 is communicated with the installation cavity. It can be understood that at least part of the positive projection of the concentrator 6 toward the second side wall 12 along the second direction Y overlaps with the fourth ventilation hole 122, and at least part of the positive projection of the LED component 4 toward the second side wall 12 along the second direction Y overlaps with the fourth ventilation hole 122. For example, part of the positive projection of the concentrator 6 toward the second side wall 12 along the second direction Y overlaps with the fourth ventilation hole 122, and part of the positive projection of the LED component 4 toward the second side wall 12 along the second direction Y overlaps with the fourth ventilation hole 122, thereby ensuring that the gap between the LED component 4 and the concentrator 6 can be opposite to the fourth ventilation hole 122. With such arrangement, cold air from the outside enters between the LED component 4 and the concentrator 6 from the fourth ventilation hole 122 below, and hot air flows out from the third ventilation hole 112 above the LED lens module 100. With the continuous entry of cold air and the continuous discharge of hot air to take away the heat accumulated between the LED component 4 and the concentrator 6, it can be understood that the arrangement of the third ventilation hole 112 and the fourth ventilation hole 122 increases the convection speed of cold and hot air, which is beneficial to further increase the flow rate of hot air, thereby further accelerating the dissipation of heat from the third ventilation hole 112, which is beneficial to further reduce the ambient temperature of the LED component 4.

[0105] In some embodiments of the present application, Figure 3 , Figure 4and Figure 8 As shown, along the second direction Y, the concentrator 6 has a third end face 61 and a fourth end face 62 arranged at intervals on one side close to the LED component 4, the third end face 61 is provided with a plurality of first ventilation grooves 611, each of the first ventilation grooves 611 is recessed inwardly toward the concentrator 6 and extends along the second direction Y, and the plurality of first ventilation grooves 611 are arranged in sequence along the third direction Z, and the fourth end face 62 is provided with a plurality of second ventilation grooves 621, each of the second ventilation grooves 621 is recessed inwardly toward the concentrator 6 and extends along the second direction Y, and the plurality of second ventilation grooves 621 are arranged in sequence along the third direction Z.

[0106] Specifically, a third end face 61 and a fourth end face 62 are formed on one side of the concentrator 6 close to the LED component 4, and the third end face 61 and the fourth end face 62 are arranged at intervals along the second direction Y, wherein the third end face 61 is located above the fourth end face 62, and further, the third end face 61 is provided with a plurality of first ventilation grooves 611 arranged in sequence along the third direction Z, each of the first ventilation grooves 611 is recessed inwardly toward the concentrator 6 and extends along the second direction Y, and the fourth end face 62 is provided with a plurality of second ventilation grooves 621 arranged in sequence along the third direction Z, each of the second ventilation grooves 621 is recessed inwardly toward the concentrator 6 and extends along the second direction Y. Extending along the second direction Y, it is configured in this way, so that part of the cold air can enter between the LED component 4 and the concentrator 6 from the second ventilation groove 621, and part of the hot air after heat exchange can also flow out from between the LED component 4 and the concentrator 6 through the first ventilation groove 611. That is to say, the setting of the first ventilation groove 611 and the second ventilation groove 621 accelerates the flow of hot air between the LED component 4 and the concentrator 6, and can take away the hot air between the LED component 4 and the concentrator 6 more quickly, thereby effectively reducing the temperature between the LED component 4 and the concentrator 6, and finally quickly dissipating the heat at the LED component 4 into the environment.
