[0052] The core of this application is to provide a lighting module to improve the heat dissipation efficiency of the lighting module.
[0053] Another core of the present application is to provide a vehicle having the above-mentioned lighting module.
[0054] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0055] With the advancement of vehicle technology, headlights are becoming more versatile. Lighting modules not only provide illumination but also project static patterns or dynamic images onto the road ahead. To achieve optimal projection performance, the lighting module's power must be kept high. This generates significant heat, and if this heat cannot be dissipated promptly, its service life will be significantly impacted.
[0056] like Figure 1 and Figure 2As shown, an embodiment of the present application discloses a lighting module, including a circuit board 100, a light source module 101 and a heat dissipation assembly 200. The main heat transferred from the light source module 101 to the circuit board 100 can be transferred to the heat conductive insert 202 through the heat conductive part of the circuit board 100, and is discharged by the heat dissipation copper tube 203 fixed on the heat conductive insert 202, thereby improving the heat dissipation efficiency of the lighting module and extending the service life of the lighting module.
[0057] The following will be combined Figures 1 to 11 The lighting module disclosed in the embodiments of the present application is specifically explained and illustrated.
[0058] Among them, such as Figure 1 As shown, the light source module 101 is disposed on one side of the circuit board 100. A heat conducting portion is disposed on the side of the circuit board 100 facing away from the light source module 101, and the heat conducting portion is disposed correspondingly to the light source module 101. For ease of understanding, the two opposite sides of the circuit board 100 are defined as a first side and a second side, respectively. The light source module 101 is located on the first side of the circuit board 100, while the heat conducting portion is disposed on the second side of the circuit board 100, opposite the light source module 101, so that the heat conducting portion can conduct heat emitted by the light source module 101.
[0059] In order to achieve the heat dissipation of the lighting module, such as Figure 1 and Figure 2 As shown, the heat dissipation assembly 200 includes a thermally conductive gasket 201, a thermally conductive insert 202 and at least one heat dissipation copper tube 203. The thermally conductive gasket 201 is arranged on the side surface of the circuit board 100 away from the light source module 101, that is, the second side of the circuit board 100. The heat dissipation copper tube 203 is located on the side of the thermally conductive gasket 201 away from the circuit board 100, and the heat dissipation copper tube 203 can be directly fixed to one side of the thermally conductive insert 202 by welding. The thermally conductive gasket 201 is provided with a hollow area 2011, so that the other side of the thermally conductive insert 202 can directly or indirectly contact the heat conduction part of the circuit board 100 through the hollow area 2011 of the thermally conductive gasket 201, so that the main heat transferred from the light source module 101 to the circuit board 100 can be transferred to the thermally conductive insert 202 through the heat conduction part of the circuit board 100, and is conducted out by the heat dissipation copper tube 203 fixed on the thermally conductive insert 202, thereby improving the heat dissipation efficiency of the lighting module and extending the service life of the lighting module.
[0060] The light source module 101, serving as the light source for the illumination module, is mounted on the circuit board 100. The light source module 101 can include multiple micron-scale light-emitting points, each of which can be independently controlled, for example, to illuminate or de-emit light, or to vary the intensity of the light emitted by a single point. The light-emitting points are controlled by conventional methods, such as a control circuit composed of thin-film transistors (TFTs), and are not described in detail herein. The light source module 101 can have an illumination mode and a projection mode, and the light-emitting mode of the light-emitting points can be adjusted according to the operating mode. For example, in illumination mode, all light-emitting points can be controlled to emit white light to maximize illumination brightness, while in projection mode, some light-emitting points can be controlled to emit light, thereby projecting a specific pattern. Those skilled in the art will appreciate that if the light-emitting points in each light source module 101 are composed of red, green, and blue light-emitting points, then various colors of light can be modulated through color combinations, and dynamic images can be projected by combining these colors with existing display technologies. Alternatively, the light source module 101 can include multiple light-emitting devices arranged in an array, which can utilize Mini LEDs or Micro LEDs. Among them, Mini LED is a light-emitting device with a size of tens of microns, and Micro LED is a light-emitting device with a size of less than ten microns.
[0061] In some embodiments, the heat-conducting insert 202 can directly contact the heat-conducting portion of the circuit board 100, so that the main heat transferred from the light source module 101 to the circuit board 100 is directly transferred to the heat-conducting insert 202 through the heat-conducting portion of the circuit board 100, and is then discharged by the heat-dissipating copper tube 203 fixed to the heat-conducting insert 202, thereby improving the heat dissipation efficiency of the lighting module. Of course, the heat-conducting insert 202 can also indirectly contact the heat-conducting portion of the circuit board 100. Specifically, Figure 2 and Figure 4 As shown, the thermally conductive insert 202 includes a planar portion 2021 and a raised portion 2022. The raised portion 2022 protrudes from the planar portion 2021 toward the side closest to the circuit board 100, allowing the raised portion 2022 to mate with the thermally conductive portion. A first predetermined gap filled with thermally conductive material 207 is defined between the raised portion 2022 and the thermally conductive portion. A second predetermined gap filled with thermally conductive material 207 is defined between the planar portion 2021 and the circuit board 100, with the first predetermined gap being smaller than the second predetermined gap. The first predetermined gap can be 0.05 mm, and the second predetermined gap can be 0.2 mm. This allows the thermally conductive insert 202 to fully adhere to the thermally conductive portion of the circuit board 100 while ensuring a thinner thickness of the thermally conductive material 207 in the core heat dissipation area of the circuit board 100, thereby improving heat dissipation efficiency. It should be noted that the core heat dissipation area of the circuit board 100 is the area between the raised portion 2022 of the thermally conductive insert 202 and the thermally conductive portion of the circuit board 100.
[0062] In the above embodiment, the thermal conductive material 207 can be made of filling materials that can achieve thermal conductivity, such as thermal conductive glue, thermal conductive silicone grease, and flexible thermal conductive pads. Of course, the thermal conductive material 207 can also be made of other materials with thermal conductive properties, which will not be listed here one by one.
[0063] In some embodiments, as Figure 2 and Figure 3 As shown, the heat dissipation copper tube 203 may include a heat absorbing tube section 2031, a heat dissipation tube section 2032 and a connecting tube section 2033. The heat absorbing tube section 2031 has a connecting surface 2034 connected to the heat conductive insert 202, so that the heat absorbing tube section 2031 can be welded to the heat conductive insert 202 through the connecting surface 2034. The two ends of the connecting tube section 2033 are respectively connected to the heat absorbing tube section 2031 and the heat dissipation tube section 2032, so that the heat conductive insert 202 transfers the main heat of the light source module 101 to the circuit board 100 through the heat absorbing tube section 2031, the connecting tube section 2033 and the heat dissipation tube section 2032 in sequence to export the lighting module.
[0064] To further enhance heat dissipation, in some embodiments, the inner wall of the heat dissipating copper tube 203 may be formed with microchannels, and the interior of the heat dissipating copper tube 203 may be filled with coolant, allowing the coolant to flow through the microchannels throughout the heat dissipating copper tube 203, thereby enhancing heat dissipation. The coolant may be water, or a specialized coolant such as alcohol or glycerin. Furthermore, the interior of the heat dissipating copper tube 203 may be under negative pressure to lower the boiling point of the coolant within the heat dissipating copper tube 203.
[0065] In the above embodiment, when the heat generated by the light source module 101 is transferred to the heat-absorbing pipe section 2031 of the heat-dissipating copper tube 203, the coolant in the heat-absorbing pipe section 2031, which is under a negative pressure, evaporates due to the heat. The coolant then flows from the heat-absorbing pipe section 2031 through the connecting pipe section 2033 to the heat-dissipating pipe section 2032. The temperature of the heat-dissipating pipe section 2032 is lower than that of the heat-dissipating pipe section 2031. The gaseous coolant condenses upon encountering cold in the heat-dissipating pipe section 2032, transferring the heat away from the lighting module. The coolant in the heat-dissipating pipe section 2032 then gradually flows back from the heat-dissipating pipe section 2032 to the heat-absorbing pipe section 2031 under the capillary action of the microchannels on the inner wall of the heat-dissipating copper tube 203. Specifically, because the inner wall of the heat-dissipating copper tube 203 has numerous tiny microchannels, the coolant is adsorbed within these microchannels. Due to the combined effects of surface tension, cohesive forces, and adhesive forces, the coolant gradually flows back from the heat-dissipating pipe section 2032 to the heat-absorbing pipe section 2031. Therefore, the coolant can circulate back and forth between the heat absorbing pipe section 2031 and the heat dissipating pipe section 2032, thereby continuously transferring the heat generated by the lighting module from the heat absorbing pipe section 2031 to the heat dissipating pipe section 2032 and dissipating it outside the lighting module.
[0066] In some embodiments, the heat dissipation copper tube 203 can be bent twice to form a structure similar to a "匚" shape, or the heat absorption tube section 2031 and the heat dissipation tube section 2032 of the heat dissipation copper tube 203 can be arranged in a staggered manner. As Figure 2 shown, in the vertical direction, the heat absorption tube section 2031 can be arranged above or below the heat dissipation tube section 2032. Among them, for the connecting tube section 2033 connecting the heat absorption tube section 2031 and the heat dissipation tube section 2032, it can form a certain angle with the heat absorption tube section 2031 and the heat dissipation tube section 2032. As Figure 2 shown, the connecting tube section 2033 can be arranged perpendicular to both the heat absorption tube section 2031 and the heat dissipation tube section 2032. In addition, it can also be set as an acute angle or an obtuse angle according to actual needs, which is not limited in this application.
[0067] In some embodiments, the heat absorption tube section 2031 can have a connecting surface 2034 connected to the heat conduction insert 202, and the connecting surface 2034 can increase the effective contact area between the heat dissipation copper tube 203 and the heat conduction insert 202, thereby improving the heat dissipation efficiency. The heat absorption tube section 2031 can be a cuboid structure or other structures, such as a flat structure. For the convenience of processing and manufacturing the heat absorption tube section 2031, the heat dissipation copper tube 203 can be integrally made of a round tube, and the heat absorption tube section 2031 is processed into a flat structure with two opposite planes by stamping, extrusion, etc. on the heat absorption tube section 2031.
[0068] In some embodiments, as Figures 2 to 4 shown, two heat dissipation copper tubes 203 can be used, and the heat absorption tube sections 2031 of the two heat dissipation copper tubes 203 are adjacent and arranged side by side up and down, so that the adjacent heat absorption tube sections 2031 are arranged more closely, thereby better covering the heat conduction part on the circuit board. And the heat absorption tube sections 2031 are arranged side by side up and down, which is also convenient for the installation and fixation of the heat dissipation copper tube 203.
[0069] In the above embodiments, as Figure 2 shown, in the vertical direction, in the heat dissipation copper tube 203 located above, the heat dissipation tube section 2032 is closer to the upper side relative to the heat absorption tube section 2031, so that in addition to the capillary action, the heat dissipation tube section 2032 can accelerate the reflux to the heat absorption tube section 2031 under the action of gravity. Therefore, the coolant in the heat dissipation copper tube 203 can flow back to the heat absorption tube section 2031 more quickly. At the same time, in the heat dissipation copper tube 203 located below, the heat dissipation tube section 2032 is closer to the lower side relative to the heat absorption tube section 2031. In this way, enough space can be maintained between the heat dissipation tube sections 2032 of the upper heat dissipation copper tube 203 and the lower heat dissipation copper tube 203 to avoid affecting each other's heat dissipation effect.
[0070] In some embodiments, as Figure 2As shown, the heat dissipation assembly 200 may further include a mounting plate 204, and the mounting plate 204 is located between the thermal pad 201 and the heat dissipation copper tube 203. A recess 2041 for mounting the heat dissipation insert 202 is provided on the side of the mounting plate 204 facing away from the heat dissipation copper tube 203, so that the heat dissipation insert 202 can be installed in the recess 2041. A mounting opening 2042 is provided at the bottom of the recess 2041, so that the heat dissipation copper tube 203 can pass through the mounting opening 2042 and be fixed to the heat dissipation insert 202 by welding.
[0071] In some embodiments, as Figure 1 and Figure 2 As shown, the heat dissipation assembly 200 further includes heat dissipation fins 205. A plurality of heat dissipation fins 205 may be provided, each of which is parallel to and spaced apart from each other. The heat dissipation fins 205 may be arranged perpendicular to the heat absorption pipe segment 2031 and the heat dissipation pipe segment 2032. The heat dissipation fins 205 are in contact with the heat dissipation copper tube 203, with the heat absorption pipe segment 2031 located at one end of the heat dissipation fins 205. A through hole for accommodating the heat dissipation pipe segment 2032 is provided on the heat dissipation fins 205, thereby allowing the heat from the heat dissipation pipe segment 2032 to be better dissipated through the heat dissipation fins 205.
[0072] To further enhance heat dissipation, the heat-absorbing pipe segment 2031 also has a bonding surface, which is disposed opposite the connecting surface 2034 and mates with the ends of the heat-dissipating fins 205. This allows heat absorbed by the heat-dissipating pipe segment 2031 and transferred from the heat-conducting insert 202 to be dissipated outside the lighting module via the heat-dissipating fins 205. The bonding surface of the heat-dissipating copper tube 203 can be formed by stamping or extruding a round tube.
[0073] In some embodiments, as Figure 1 and Figure 2 As shown, the heat dissipation assembly 200 may further include a fan assembly 206. The fan assembly 206 may include a heat dissipation fan 2061 and a fan bracket 2062 for fixing the heat dissipation fan 2061. The fan bracket 2062 is connected to the mounting plate 204 to fix the heat dissipation fan 2061 below the heat dissipation fins 205. The heat dissipation fan 2061 has an air inlet and an air outlet. The heat dissipation fan 2061 may be arranged toward the gap between adjacent heat dissipation fins 205 through the air outlet to provide heat dissipation airflow, thereby improving the heat exchange efficiency of the heat dissipation fins 205.
[0074] It should be noted that, in the above embodiment, the thermally conductive insert 202 and the thermally conductive gasket 201 can be made of materials with high thermal conductivity, such as copper and aluminum, to improve the heat dissipation efficiency of the lighting module.
[0075] like Figures 5 to 13 As shown, the lighting module also includes a lens module 300 and a support platform 400. Figure 5 As shown, at least one of the lens module 300 and the support platform 400 is provided with a sliding member 301, and the other is provided with a sliding groove 401 that cooperates with the sliding member 301, and the sliding groove 401 can extend in a direction parallel to the lens module 300, and at the same time, the opening side 4011 of the sliding groove 401 is set toward or away from the direction of the lens module 300. The sliding member 301 and the sliding groove 401 are slidably matched to achieve the focus of the lens module 300. After the focus of the lens module 300 is completed, it can be locked along the side wall direction perpendicular to the sliding groove 401 by fasteners 302 such as bolts. It can be seen from the above embodiment that the sliding member 301 and the sliding groove 401 are slidably matched, as shown in FIG. Figure 6 As shown, displacement in the z- and y-directions can be constrained, preventing the position of the lens module 300 from shifting when the lens module 300 is tightened, thereby improving focusing stability. Furthermore, since the fastener 302 is tightened perpendicular to the sidewalls of the slideway 401, there is no need to consider the y-direction depth, thus reducing the size of the lens module 300. Furthermore, the tightening direction of the fastener 302 aligns with the process installation direction, shortening production time and improving production efficiency.
[0076] In some embodiments, as Figure 12 and Figure 13 As shown, the sliding member 301 can be a rectangular plate strip, and two sliding members 301 can be used. The two sliding members 301 can be symmetrically arranged on either side of the lens module 300 or the support platform 400. At the same time, the slide 401 can adopt an I-shaped structure or a U-shaped structure that matches the sliding member 301, so that the cross-sectional shape of the slide 401 body is I-shaped or U-shaped. This allows the slide 401 body to have a large contact area with the sliding member 301, ensuring the stability of focusing and the connection strength. In addition, two waist-shaped holes 3011 are provided on the sliding member 301, and mounting holes 4012 are provided on the two side walls of the slide 401 respectively, which are compatible with the waist-shaped holes 3011 of the sliding member 301. After the lens module 300 is focused through the waist-shaped holes 3011, a fastener 302 such as a bolt can be used to pass through the waist-shaped holes 3011 and the mounting holes 4012 to achieve locking between the lens module 300 and the support platform 400. Of course, the sliding member 301 may also adopt a columnar structure, and the slide groove 401 may adopt a C-shaped structure adapted to the sliding member 301, so that the groove body of the slide groove 401 can have a larger contact area with the sliding member 301, thereby ensuring the focusing stability and connection strength.
[0077] In some embodiments, as Figures 5 to 8As shown, the slide groove 401 can be disposed on the support platform 400, with the open side 4011 of the slide groove 401 facing the lens module 300. That is, the open sides 4011 of the two slide grooves 401 are disposed opposite each other. At the same time, the outer end of the slide groove 401, i.e., the end closest to the lens module 300, is connected to the groove body of the slide groove 401, allowing the slider 301 to slide into the groove body of the slide groove 401 from the outer end of the slide groove 401. The slider 301 can also be disposed on the lens module 300. During installation, the slider 301 of the lens module 300 is slid into the groove body of the slide groove 401 through the outer end of the slide groove 401, so that the waist-shaped hole 3011 of the slider 301 aligns with the mounting hole 4012 on the side wall of the slide groove 401. After adjusting to the appropriate position, the lens module 300 and the support platform 400 are locked by passing a fastener 302, such as a bolt, through the mounting hole 4012 and the waist-shaped hole 3011.
[0078] In some embodiments, as Figure 9 and Figure 10 As shown, the slide groove 401 can also be provided on the lens module 300, and the open side 4011 of the slide groove 401 is provided in a direction away from the lens module 300, that is, the open sides 4011 of the two slide grooves 401 are provided opposite to each other, and the inner end of the slide groove 401, that is, the end close to the support platform 400, is connected to the groove body of the slide groove 401, so that the sliding member 301 slides into the inner end of the slide groove 401. At the same time, the sliding member 301 can be provided on the support platform 400. During installation, the inner end of the slide groove 401 of the sliding member 301 is moved closer to the sliding member 301 of the support platform 400 until the sliding member 301 enters the groove body of the slide groove 401, so that the waist-shaped hole 3011 of the sliding member 301 corresponds to the mounting hole 4012 on the side wall of the slide groove 401. After adjusting to the appropriate position, the fastener 302 such as a bolt is passed through the mounting hole 4012 and the waist-shaped hole 3011 to achieve locking between the lens module 300 and the support platform 400.
[0079] In some embodiments, as Figures 5 to 7 As shown, the support platform 400 may include a lens bracket 402, and the lens bracket 402 is located between the lens module 300 and the heat dissipation assembly 200, and one of the sliding member 301 and the sliding groove 401 is disposed on the lens bracket 402. Figures 5 to 7As shown, the slider 301 can be set on the lens module 300, and the slide groove 401 can be set on the lens holder 402, with the open side 4011 of the slide groove 401 facing the lens module 300. That is, the open sides 4011 of the two slide grooves 401 are arranged opposite each other. At the same time, the outer end of the slide groove 401, that is, the end close to the lens module 300, is connected to the groove body of the slide groove 401, so that the slider 301 slides into the groove body of the slide groove 401 from the outer end. When installing, the slider 301 of the lens module 300 is slid into the groove body of the slide groove 401 through the outer end of the slide groove 401, so that the waist-shaped hole 3011 of the slider 301 corresponds to the mounting hole 4012 on the side wall of the slide groove 401. After adjusting to the appropriate position, the lens module 300 and the lens holder 402 are locked by fasteners 302 such as bolts passing through the mounting hole 4012 and the waist-shaped hole 3011. In addition, the lens bracket 402 and the mounting plate 204 of the heat dissipation component 200 are fixed together by screws, and a thermal insulation gasket 500 and a first seal 600 can be set between the lens bracket 402 and the heat dissipation component 200 to achieve the effect of sealing and heat insulation. At the same time, the lens module 300 and the lens bracket 402 can be sealed by the second seal 700, wherein the first seal 600 and the second seal 700 can be sealed by silicone sealing rings, etc.
[0080] Of course, if Figure 9 and Figure 10 As shown, the slide groove 401 can also be set on the lens module 300, with the open side 4011 of the slide groove 401 facing away from the lens module 300, that is, the open sides 4011 of the two slide grooves 401 are arranged opposite to each other, and the inner end of the slide groove 401, that is, the end close to the lens holder 402, is connected to the groove body of the slide groove 401, so that the sliding member 301 slides into the inner end of the slide groove 401. At the same time, the sliding member 301 can be set on the lens holder 402. During installation, the inner end of the slide groove 401 of the sliding member 301 is moved closer to the sliding member 301 of the lens holder 402 until the sliding member 301 enters the groove body of the slide groove 401, so that the waist-shaped hole 3011 of the sliding member 301 corresponds to the mounting hole 4012 on the side wall of the slide groove 401. After adjusting to the appropriate position, the lens module 300 and the lens holder 402 are locked by fasteners 302 such as bolts passing through the mounting hole 4012 and the waist-shaped hole 3011.
[0081] In some embodiments, as Figure 11As shown, the support platform 400 may include a heat dissipation assembly 200, with one of the slider 301 and the slide 401 disposed on the heat dissipation assembly 200. This eliminates the need for the lens holder 402, thereby reducing the number of parts, the size of the lighting module, and the cost. Specifically, the slide 401 may be disposed on the lens module 300, with the open side 4011 of the slide 401 facing the lens module 300. This means that the open sides 4011 of the two slides 401 are disposed opposite each other. Furthermore, the inner end of the slide 401, i.e., the end closest to the heat dissipation assembly 200, is connected to the body of the slide 401, allowing the slider 301 to slide into the inner end of the slide 401. Furthermore, the slider 301 may be disposed on the heat dissipation assembly 200. During installation, the inner end of the slide groove 401 of the slider 301 is moved closer to the slider 301 of the heat dissipation assembly 200 until the slider 301 enters the groove body of the slide groove 401, so that the waist-shaped hole 3011 of the slider 301 aligns with the mounting hole 4012 on the side wall of the slide groove 401. After adjusting to the appropriate position, fasteners 302 such as bolts are passed through the mounting hole 4012 and the waist-shaped hole 3011 to lock the lens module 300 and the heat dissipation assembly 200. In addition, a thermal insulation gasket 500 and a first sealing member 600 can be placed between the lens holder 402 and the heat dissipation assembly 200 to achieve a sealing and heat insulation effect.
[0082] Of course, the slider 301 can also be set on the lens module 300, and the slide groove 401 can be set on the heat dissipation assembly 200, and the open side 4011 of the slide groove 401 is set in the direction of the lens module 300, that is, the open sides 4011 of the two slide grooves 401 are set opposite each other, and the outer end of the slide groove 401, that is, the end close to the lens module 300, is connected to the groove body of the slide groove 401, so that the slider 301 slides into the groove body of the slide groove 401 from the outer end. When installing, the slider 301 of the lens module 300 is slid into the groove body of the slide groove 401 through the outer end of the slide groove 401, so that the waist-shaped hole 3011 of the slider 301 corresponds to the mounting hole 4012 on the side wall of the slide groove 401. After adjusting to the appropriate position, the lens module 300 and the heat dissipation assembly 200 are locked by passing the fastener 302 such as a bolt through the mounting hole 4012 and the waist-shaped hole 3011.
