Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an automotive light source kit. Background Technology

[0002] With the increasing popularity of LED car lights, the requirements for heat dissipation in LED car lights within limited installation space are also increasing. The heat dissipation effect of LED car lights directly affects the power of LED car lights, and poor heat dissipation can easily lead to light attenuation or even burn out electronic components.

[0003] Currently, LED automotive lights typically consist of a heat sink housing, a substrate with LED beads, and a circuit board. Cooling of LED automotive lights is achieved by configuring heat dissipation fins on the heat sink housing, but this technical solution still has the drawback of poor heat dissipation.

[0004] Therefore, a car lighting kit with good heat dissipation needs to be designed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing an automotive light source kit that at least solves the aforementioned technical problems and has the advantage of good heat dissipation.

[0006] To achieve the above objectives, this utility model provides an automotive light source kit, comprising:

[0007] The housing has an internal assembly cavity, and its peripheral wall has an air inlet and a heat dissipation outlet that communicate with the assembly cavity;

[0008] The circuit board is disposed in the assembly cavity of the housing and is electrically connected to an external power source;

[0009] A fan is disposed in the assembly cavity of the housing and is electrically connected to the circuit board;

[0010] An LED light source assembly is disposed on the housing, with one end extending into the assembly cavity and electrically connected to the circuit board.

[0011] Optionally, the heat dissipation vent includes: a first heat dissipation vent disposed on the two side peripheral walls adjacent to the air inlet.

[0012] Optionally, the first heat dissipation vent is a plurality of spaced and horizontally arranged elongated heat dissipation holes.

[0013] Optionally, the heat dissipation vent further includes a second heat dissipation vent disposed on the peripheral wall opposite to the air inlet.

[0014] Optionally, an assembly ring groove is formed in the assembly cavity of the housing, and the fan is engaged in the assembly ring groove; the rotation axis of the fan is arranged perpendicular to the extension direction of the LED light source assembly, and the rotation axis of the fan is parallel to the plane of the circuit board.

[0015] Optionally, the LED light source assembly includes a metal substrate with multiple light-emitting chips integrated thereon, and LED light sources symmetrically mounted on both sides of the metal substrate.

[0016] Optionally, the LED light source assembly further includes a heat-conducting copper tube that covers a portion of the metal substrate and is arranged along the extension direction of the LED light source assembly; at least a portion of the heat-conducting copper tube is in contact with the inner wall of the housing, and one end extends into the assembly cavity.

[0017] Optionally, a plug electrically connected to the circuit board is disposed inside the housing, and the extension direction of the plug is configured in the same direction as the rotation axis of the fan.

[0018] Optionally, the outer surfaces of the two side walls of the housing corresponding to the first heat dissipation vent are configured with an uneven surface.

[0019] Optionally, the housing includes a symmetrically arranged left housing and a right housing, the left housing and the right housing being made of aluminum; a portion of the LED light source assembly is sandwiched between the left housing and the right housing.

[0020] Compared with the prior art, the advantages of this application are:

[0021] Because the housing of this automotive light source kit has an assembly cavity inside, with air inlets and heat dissipation vents on the peripheral walls; the circuit board and fan are configured in the assembly cavity of the housing; one end of the LED light source assembly extends into the assembly cavity and is electrically connected to the circuit board. In this way, the large amount of heat generated by the LED light source assembly can not only be dissipated directly through the part of the housing that is in contact with it, but the heat transferred to the assembly cavity of the housing can also be quickly expelled from the housing by the fan, thus achieving a rapid cooling effect.

[0040] Please refer to Figures 1 to 7 This utility model embodiment provides an automotive light source kit 100, including: a housing 1, a circuit board 2, a fan 3, and an LED light source assembly 4.

[0041] The housing 1 has an assembly cavity a inside, and its peripheral wall has an air inlet b and a heat dissipation vent communicating with the assembly cavity a. Preferably, the housing 1 is made of a material with good thermal conductivity, such as aluminum.

[0042] Circuit board 2 is disposed in assembly cavity a of housing 1 and is electrically connected to an external power supply (not shown in the figure). Specifically, circuit board 2 is prior art, so it will not be elaborated on here, as long as it can realize the control of the electronic components of automotive light source kit 100.

[0043] Fan 3 is disposed in assembly cavity a of housing 1 and electrically connected to circuit board 2. Preferably, the air inlet end of fan 3 is positioned close to and directly facing air inlet b, thereby increasing the air intake volume. Optionally, fan 3 is electrically connected to circuit board via wires (not shown in the figure).

[0044] The LED light source assembly 4 is disposed on the housing 1, with one end extending into the assembly cavity a of the housing 1 and electrically connected to the circuit board 2. Optionally, the LED light source assembly 4 is directly soldered onto the circuit board 2 to achieve electrical connection with the circuit board 2.

[0045] In this way, the large amount of heat generated by the LED light source component 4 can not only be dissipated directly through the part of the housing 1 that is in contact with it, but the heat transferred to the assembly cavity a of the housing 1 can also be quickly discharged from the housing 1 by the fan 3 to achieve the effect of rapid cooling.

[0046] Alternatively, please refer to Figure 2 , Figure 3 and Figure 5In this embodiment, the heat dissipation vent includes a first heat dissipation vent c1. The first heat dissipation vent c1 is disposed on the two side peripheral walls adjacent to the air inlet b. Thus, the cool air drawn in by the fan 3, after carrying away the heat in the assembly cavity a of the housing 1, can be discharged from the first heat dissipation vent c1 on both sides. Optionally, the first heat dissipation vent c1 is a plurality of spaced and laterally arranged elongated heat dissipation holes o2. The plurality of spaced and laterally arranged elongated heat dissipation holes o2 are roughly in the same direction as the air flow inside the housing 1, so their heat dissipation effect is better.

[0047] To further improve heat dissipation, optionally, please refer to... Figure 4 and Figure 5 In this embodiment, the heat dissipation vent further includes a second heat dissipation vent c2 disposed on the peripheral wall opposite to the air inlet b. Thus, the housing 1 can simultaneously exhaust hot air from the housing 1 from three directions: the two peripheral walls adjacent to the air inlet b, and the peripheral wall opposite to the air inlet b, resulting in better heat dissipation.

[0048] Alternatively, please refer to Figure 6 In this embodiment, an assembly ring groove d is formed in the assembly cavity a of the housing 1, and the fan 3 is engaged in the assembly ring groove d. The rotation axis of the fan 3 is perpendicular to the extension direction of the LED light source assembly 4, and the rotation axis of the fan 3 is parallel to the plane of the circuit board 2. In this way, the cool air drawn in by the fan 3 can directly remove the heat generated on the upper and lower surfaces of the circuit board 2 and the heat from the surface of the LED light source assembly 4 extending into the assembly cavity a, without being obstructed by the circuit board 2; the airflow is smoother and the heat dissipation effect is better.

[0049] To reduce the size of the automotive light source kit 100 while increasing its power, optionally, please refer to... Figure 5 In this embodiment, the LED light source assembly 4 includes a metal substrate 41 with multiple light-emitting chips integrated thereon, and LED light sources 42 symmetrically mounted on both sides of the metal substrate 41. Specifically, the LED light sources 42 here are high-power LED light sources 42. In this way, the power of the LED light source assembly 4 can be significantly increased while reducing its size, thereby improving the luminous intensity of the automotive light source kit 100.

[0050] In order to quickly transfer the heat generated on the LED light source assembly 4 to the assembly cavity a of the housing 1, so that the fan 3 can remove the heat, optionally, please refer to Figures 5 to 7In this embodiment, the LED light source assembly 4 further includes a heat-conducting copper pipe 43. The heat-conducting copper pipe 43 covers a portion of the metal substrate 41 and is arranged along the extending direction of the LED light source assembly 4; at least a portion of the heat-conducting copper pipe 43 is in contact with the inner wall of the housing 1, and one end extends into the assembly cavity a. Specifically, an assembly groove e is formed inside the housing 1 that matches the outer periphery of the heat-conducting copper pipe 43 and communicates with the assembly cavity a of the housing 1. Thus, the heat-conducting copper pipe 43 can transfer a portion of the heat from the metal substrate 41 to the housing 1 for heat dissipation, and another portion is directed into the assembly cavity a of the housing 1 for heat dissipation by the fan 3.

[0051] To facilitate the connection of the automotive lighting kit 100 to an external power source, optionally, please refer to... Figure 3 , Figure 4 and Figure 6 In this embodiment, a plug 5 electrically connected to the circuit board 2 is disposed inside the housing 1, and the extension direction of the plug 5 is arranged in the same direction as the rotation axis of the fan 3. Specifically, the plug 5 can be electrically connected to the circuit board 2 via a wire. In order to protect the plug 5, a plug protective sleeve 13 is formed on the outer periphery of the housing 1 corresponding to the plug 5. The plug protective sleeve 13 can be spaced around the axial outer periphery of the plug pins 51 of the plug 5 to protect the connection safety between the plug 5 and the external socket (not shown in the figure).

[0052] To improve the heat dissipation of housing 1, optionally, please refer to... Figure 2 and Figure 3 In this embodiment, the outer surfaces of the two side walls of the housing 1 corresponding to the first heat dissipation port c1 are arranged with uneven surfaces. Because the outer surface of the housing 1 is arranged with uneven surfaces, the surface area is increased within a certain volume, that is, the heat dissipation area of ​​the housing 1 is increased, further improving the heat dissipation effect of the housing 1.

[0053] To facilitate the assembly of the 100 components of this automotive lighting kit, optionally, please refer to... Figure 5 and Figure 7In this embodiment, the housing 1 includes a symmetrically arranged and overlapping left housing 11 and a right housing 12, both made of aluminum. A portion of the LED light source assembly 4 is sandwiched between the left housing 11 and the right housing 12. Specifically, during assembly, the circuit board 2, fan 3, and LED light source assembly 4 are first connected and assembled onto one of the left housing 11 or the right housing 12. The other of the left housing 11 or the right housing 12 is then positioned using the positioning protrusion 121 and positioning hole o1 on its mounting surface, and finally secured with screws 6. Of course, in other embodiments, the left housing 11 and the right housing 12 can also be secured in other ways, such as by snap-fit ​​fixing; no specific method is limited. It is understood that the assembly cavity a, assembly ring groove d, assembly through groove e, and the structure of the fixing plug 5 in the housing 1 are all formed by the cooperation of the left housing 11 and the right housing 12.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the substance of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
