Description

Technical Field

[0001] The present application relates to the technical field of automobile lamps, and in particular to a radiator, an optical module and a vehicle. Background Art

[0002] Conventional LED high / low beam lens module designs typically apply thermal adhesive to the surface where the LED circuit board contacts the heat sink for optimal heat dissipation. Different brands and models of thermal adhesive come in different colors, such as white, off-white, and dark gray. When the circuit board is mounted on the heat sink, the thermal adhesive squeezes and overflows to the edge of the board. This overflow is visible from the outside of the lens. Because the color of the thermal adhesive differs from the color of the module's structural components, this can result in a poor appearance.

[0003] Furthermore, LED circuit boards typically use aluminum, copper, or FR4. Due to manufacturing limitations, the natural color of the materials often shows through the edges of the circuit boards, such as the silvery-white color of aluminum, the reddish-brown color of copper, and the white color of FR4. These materials differ from the color of the module components, making the edges of the circuit boards visible from outside the lens, thus affecting the aesthetics of the headlight.

[0040] like Figure 1-Figure 2 , a radiator proposed in this application includes:

[0041] The heat dissipation component 100 has a mounting surface 110 , and the mounting surface 110 includes an assembly positioning area 111 for mounting the circuit board 300 ;

[0042] The blocking component 200 is disposed at least partially at the edge of the assembly positioning area 111 ; with the mounting surface 110 as a reference, the height of the blocking component 200 is greater than the height of the assembly positioning area 111 .

[0043] In this application, after applying thermal conductive glue on the surface of the assembly positioning area 111 and installing the circuit board 300, when the thermal conductive glue is squeezed and overflows, since the height of the blocking component 200 is greater than the assembly positioning area 111, as shown in FIG. Figure 2 When looking at the circuit board 300 from the side of the blocking component 200 away from the assembly positioning area 111, the color of the thermal conductive adhesive is basically not visible; and because the blocking component 200 has a certain height, it will block at least part of the edge facade of the circuit board 300, and at least part of the metal color of the edge of the circuit board 300 will not be seen, thereby improving the static appearance.

[0044] The present application has a simple structure and does not require additional placement space for the blocking component 200 between the assembly positioning area 111 and the lens 400. However, adding placement space can easily increase the total length of the optical system in the front-to-back direction, which is not conducive to the intensive layout of the vehicle lights.

[0045] This application eliminates the need for a complex shielding structure between the assembly positioning area 111 and the lens 400. This complex shielding structure, when applied to an optical system, can easily increase the overall length of the optical system along the light output direction and complicate the design of the light path layout. The blocking component 200 of this application has a simple structural design and, when applied to an optical system, does not affect light output and the formation of the intended light pattern, thereby avoiding unnecessary cost.

[0046] refer to Figure 1 In some embodiments, the blocking member 200 is arranged side by side with the edge and extends in the same direction as the edge of the adjacent assembly positioning area 111. The blocking member 200 extends along the edge of the assembly positioning area 111, providing more comprehensive shielding of the edge of the circuit board 300 in the assembly positioning area 111. When viewing the circuit board 300 from different angles away from the assembly positioning area 111, the color of the thermal conductive adhesive or the edge of the circuit board 300 is not easily visible.

[0047] The blocking component 200 is arranged side by side with the edge of the assembly positioning area 111. During the design, there is no need to add a placement space for the blocking component 200 between the assembly positioning area 111 and the lens 400. Adding a placement space can easily increase the total length of the optical system in the front-to-back direction, which is not conducive to the intensive layout of the vehicle lights; it will not affect the optical path.

[0048] refer to Figure 4 In some embodiments, the height h of the blocking member 200 protruding from the mounting surface 110 is 1.0-3.5 mm. In practical applications, if the height h of the blocking member 200 is greater than 3.5 mm, it can easily block the light path, affecting light transmission during illumination. If the height h is less than 1.0 mm, some traces of thermal adhesive and exposed metallic color of the circuit board 300 can still be seen.

[0049] refer to Figure 1 and Figure 2 In some embodiments, the heat sink includes a head and a tail, the assembly positioning area 111 is provided with a first edge 111a at one end close to the head, and the assembly positioning area 111 is provided with a second edge 111b in a width direction intersecting the head and tail arrangement direction;

[0050] The blocking component 200 includes:

[0051] a main body portion 210 , the main body portion 210 being disposed along the first edge 111 a ;

[0052] The side portion 220 is connected to the main body portion 210 , and the side portion 220 is disposed along at least a portion of the second edge 111 b .

[0053] In this application, the so-called head portion normally refers to the area near the lens 400, and the tail portion refers to the location where the heat sink fins are located. After the circuit board 300 is assembled to the positioning and mounting surface 110, the main portion 210 of the blocking component 200 is located at the head portion of the circuit board 300; the side portions 220 are combined with the main portion 210. In the width direction of the heat sink, the dimension L of the entire blocking component 200 is slightly larger than the dimension of the circuit board 300. When looking straight at the circuit board 300 from the head portion of the heat sink, the metal color of the circuit board 300 or the thermal conductive adhesive overflowing from the assembly is completely invisible, thereby further improving the static appearance.

[0054] refer to Figure 1 In some embodiments, the blocking member 200 is a blocking bar having a width W perpendicular to the height of 1.0-4.0 mm. As long as the desired blocking effect is achieved, the smaller the width W of the blocking bar, the better. Excessive width W results in redundant material and can affect light transmission during illumination.

[0055] refer to Figure 1 In some embodiments, the first edge 111a includes a segment I 111a-1 extending along the width direction of the radiator, and a segment II 111a-2 connected to the segment I 111a-1 and extending toward the tail end of the radiator, and the angle between the segment II 111a-2 and the segment I 111a-1 is an obtuse angle.

[0056] Specifically, compared to the form in which the first edge 111a only extends along the width direction of the radiator, the solution of this embodiment extends segment II 111a-2 toward the tail end of the radiator, and the first edge 111a is bent as a whole. When looking at the circuit board 300 from different lateral angles of the radiator head, the metal color of the outer periphery of the circuit board 300 or the thermal conductive adhesive overflowed from the assembly will not be seen. It is not limited to viewing from the front of the radiator head, and the visual effect is better, thereby improving the flexibility and adaptability of the solution.

[0057] refer to Figure 1-Figure 3 , the present application also provides an optical module, comprising:

[0058] A circuit board 300, the circuit board 300 being fixed to the positioning and mounting surface 110, and the circuit board 300 being provided with a light source;

[0059] The lens 400 is provided on one side of the heat dissipation component 100. The light incident surface and the light emitting surface of the lens 400 are sequentially arranged in a direction gradually away from the heat dissipation component 100, and is used to adjust the light emitted by the light source and project a light pattern on the side away from the light emitting surface;

[0060] The blocking component 200 is at least partially located between the circuit board 300 and the lens 400 .

[0061] In the present application, after applying thermal conductive glue on the surface of the assembly positioning area 111 of the circuit board 300 and installing the circuit board 300, in the case where the thermal conductive glue is squeezed and overflows, since the height of the blocking component 200 is greater than the assembly positioning area 111, when looking from the light-emitting surface side of the lens 400 to the inside of the optical module, the color of the thermal conductive glue is basically not visible; and since the blocking component 200 has a certain height, it will block at least part of the edge facade of the circuit board 300, and the metal color of at least part of the edge of the circuit board 300 will not be seen, thereby improving the static visual experience.

[0062] The present application has a simple structure and does not require an expanded placement space for the blocking component 200. However, expanding and increasing the placement space can easily increase the total length of the optical system in the front-to-back direction, which is not conducive to the intensive layout of the vehicle lights.

[0063] This application avoids designing a complex shielding structure between the circuit board 300 and the lens 400. This complex shielding structure, when applied to an optical system, can easily increase the overall length of the optical system along the light output direction and complicate the design of the light path of the vehicle lamp. The blocking component 200 of this application has a simple structural design. When applied to an optical system, it does not affect the output of light and the formation of the intended light pattern, thereby avoiding unnecessary cost.

[0064] refer to Figure 3 In some embodiments, the circuit board 300 is provided with a third edge in front of the light source in the light emitting direction, and the circuit board 300 is provided with a fourth edge on both sides of the light source in the light emitting direction;

[0065] The blocking component 200 includes:

[0066] a main body portion 210, the main body portion 210 being arranged along the third edge;

[0067] The side portion 220 is connected to the main body portion 210 and is disposed along at least a portion of the fourth edge.

[0068] In the present application, after the circuit board 300 is assembled to the positioning and mounting surface 110, the main portion 210 of the blocking component 200 is located between the circuit board 300 and the lens 400; the side portion 220 and the main portion 210 are combined and arranged, and along the width direction of the optical module, the size L of the entire blocking component 200 is slightly larger than the size of the circuit board 300. When looking at the optical module from the front of the vehicle, the metallic color of the outer periphery of the circuit board 300 or the overflowed thermal conductive adhesive color will not be seen at all, thereby further improving the static visual experience.

[0069] refer to Figure 4In some embodiments, the height difference between the blocking member 200 and the circuit board 300 is 0-1.0 mm relative to the mounting surface 110. Practical verification has shown that if the height difference between the blocking member 200 and the circuit board 300 is greater than 1.0 mm, the light path of the light source on the surface of the circuit board 300 may be blocked, affecting the transmission of light during illumination. If the height difference between the blocking member 200 and the circuit board 300 is less than 0 mm, some metallic color of the circuit board 300 may still be visible.

[0070] The present application also provides a vehicle comprising any of the above optical modules. The present application eliminates visible traces of thermal adhesive overflow from the lens's exterior, thereby preventing the appearance of thermal adhesive that differs from the color of the module's structural components. Furthermore, the edge elevation of the circuit board cannot be seen from the lens' exterior, improving the aesthetics of the headlight.

[0071] The exemplary implementation methods of the present application are described in detail above with reference to the preferred embodiments. However, it will be understood by those skilled in the art that, without departing from the concept of the present application, various variations and modifications may be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present application may be combined in various ways without exceeding the scope of protection of the present application, which is determined by the appended claims.
