[0021] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0022] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0023] See Figure 1 and Figure 2 This application provides a vehicle light 1. In some embodiments, the vehicle light 1 includes a housing 10, a light-emitting module 20, a heat sink 30, and a heat sink 40.

[0024] Combined Figure 3 The housing 10 has a receiving cavity 11. Exemplarily, the housing 10 includes a lamp housing 10a and a lamp shade 10b, with the lamp housing 10a and lamp shade 10b covering each other to form the receiving cavity 11. The material of the lamp housing 10a includes at least one of polypropylene (PP) and engineering plastic alloy (PC+ABS). The material of the lamp shade 10b includes, for example, polycarbonate (PC).

[0025] The light-emitting module 20 is disposed within the receiving cavity 11. Specifically, the light-emitting module 20 includes a light source, which is at least one of, for example, a halogen lamp, a xenon lamp, a light-emitting diode (LED), and a laser lamp. In an exemplary embodiment, the light source is a light-emitting diode, thereby improving the energy efficiency of the vehicle lamp 1 and extending its service life.

[0026] A heat sink 30 is disposed within the receiving cavity 11 and connected to the light-emitting module 20, wherein the heat sink 30 and the light-emitting module 20 can be directly or indirectly connected. A coolant is disposed within the heat sink 30. The coolant material includes, for example, at least one selected from ethylene glycol-based coolant, propylene glycol-based coolant, water-based coolant, dielectric coolant, and nanofluid.

[0027] The radiator 40 is connected to the heat dissipation pipe 30, wherein the radiator 40 and the heat dissipation pipe 30 can be directly or indirectly connected. At least a portion of the radiator 40 extends outside the receiving cavity 11, that is, a portion of the radiator 40 extends outside the receiving cavity 11, or the entire radiator 40 is located outside the receiving cavity 11.

[0028] Based on this, the condenser in the heat pipe 30 transfers the heat of the light-emitting module 20 to the heat sink 40, and part or all of the heat sink 40 extends out of the receiving cavity 11, so that the heat generated by the light-emitting module 20 can be quickly transferred to the outside of the outer shell 10, thereby improving the heat dissipation effect.

[0029] Continue reading Figures 1-3 In some embodiments, the light-emitting module 20 has a light-emitting side 21 and a backlight side 22 that are opposite to each other. The light-emitting module 20 includes, for example, a back plate and a light source. The back plate is, for example, a printed circuit board (PCB), and the light source is, for example, a light-emitting diode. The light source is fixed to one side surface of the back plate, which corresponds to the light-emitting side 21. Correspondingly, the other side of the back plate corresponds to the backlight side 22.

[0030] The heat sink 30 is located on the backlight side 22. Optionally, the heat sink 30 is directly fixed to the surface of the backlight side 22 of the light-emitting module 20, or the heat sink 30 is connected to the surface of the backlight side 22 of the light-emitting module 20 through an additional connecting structure. For example, the light-emitting module 20 includes a back plate and a light source fixed to one side of the back plate, and the heat sink 30 is fixed to the side of the back plate where the light source is not located, thereby exchanging heat more fully with the light-emitting module 20 without affecting the light output efficiency, thus improving the heat dissipation effect.

[0031] The heat sink 40 is located on the side of the heat sink 30 away from the light-emitting module 20. Optionally, the heat sink 40 is directly fixed to the surface of the heat sink 30 away from the light-emitting module 20, or the heat sink 40 is connected to the surface of the heat sink 30 away from the light-emitting module 20 through an additional connecting structure.

[0032] Based on this, the radiator 40 and the light-emitting module 20 are respectively connected to the opposite sides of the heat pipe 30. The heat generated by the light-emitting module 20 can be efficiently and quickly transferred to the radiator 40 through the coolant in the heat pipe 30, and then the heat is further discharged out of the housing cavity 11 through the radiator 40, thereby improving the heat dissipation efficiency of the headlight 1.

[0033] Continue reading Figures 1-3 In some embodiments, the heat dissipation pipe 30 includes a first connecting pipe 31, a second connecting pipe 32, a third connecting pipe 33, and a fourth connecting pipe 34, which are sequentially and sealed together in a ring shape. This ring shape can be a circular ring, an elliptical ring, a rectangular ring, or other desired shapes. The sealing connection of the first connecting pipe 31, the second connecting pipe 32, the third connecting pipe 33, and the fourth connecting pipe 34 includes at least one of the following: sealant bonding, clamp connection, and flange connection. The sealant includes, for example, at least one of silicone sealant, epoxy resin sealant, polyurethane sealant, and cyanoacrylate.

[0034] Both the first connecting pipe 31 and the third connecting pipe 33 comprise metal pipes. The material of the first connecting pipe 31 may be the same as or different from that of the third connecting pipe 33. The material of the second connecting pipe 32 may be the same as or different from that of the first connecting pipe 31. The material of the fourth connecting pipe 34 may be the same as or different from that of the first connecting pipe 31. The material of the first connecting pipe 31 may include, for example, at least one of stainless steel, copper, aluminum, nickel, and nickel alloys. The material of the third connecting pipe 33 may include, for example, at least one of stainless steel, copper, aluminum, nickel, and nickel alloys.

[0035] The light-emitting module 20 is attached to the first connecting pipe 31, and the heat sink 40 is attached to the third connecting pipe 33. In this way, the heat exchange efficiency between the light-emitting module 20 and the heat sink 30 is improved by the first connecting pipe 31, which is made of metal, and the heat exchange efficiency between the heat sink 30 and the heat sink 40 is improved by the third connecting pipe 33, which is also made of metal, thereby improving the heat dissipation efficiency of the vehicle headlight 1.

[0036] Continue reading Figures 1-3In some embodiments, the light-emitting module 20 has a first mounting plate 23 on the side facing the heat sink 30, and the heat sink 40 has a second mounting plate 41 on the side facing the heat sink 30. The material of the first mounting plate 23 may be the same as or different from the material of the first connecting pipe 31, and the material of the second mounting plate 41 may be the same as or different from the material of the first connecting pipe 31. The shape of the first mounting plate 23 may be the same as or different from the shape of the second mounting plate 41. In an exemplary embodiment, the first mounting plate 23 is rectangular, and the second mounting plate 41 is rectangular.

[0037] Furthermore, a first heat-dissipating adhesive layer is provided between the first mounting plate 23 and the first connecting pipe 31, and a second heat-dissipating adhesive layer is provided between the second mounting plate 41 and the third connecting pipe 33. The material of the first heat-dissipating adhesive layer may be the same as or different from that of the second heat-dissipating adhesive layer. The thickness of the first heat-dissipating adhesive layer may be the same as or different from that of the second heat-dissipating adhesive layer. The material of the first heat-dissipating adhesive layer includes, for example, at least one of thermally conductive grease, thermally conductive silicone, and thermally conductive epoxy resin. The material of the second heat-dissipating adhesive layer includes, for example, at least one of thermally conductive grease, thermally conductive silicone, and thermally conductive epoxy resin.

[0038] Based on this, a first heat-dissipating adhesive layer is used to fix the first mounting plate 23 and the first connecting pipe 31, and the first heat-dissipating adhesive layer also creates a larger contact area between the first mounting plate 23 and the first connecting pipe 31, thereby improving the heat dissipation effect. Similarly, a second heat-dissipating adhesive layer is used to fix the second mounting plate 41 and the third connecting pipe 33, and the second heat-dissipating adhesive layer also creates a larger contact area between the second mounting plate 41 and the third connecting pipe 33, thereby improving the heat dissipation effect.

[0039] In some embodiments, the second connecting tube 32 comprises a rubber tube. Thus, the second connecting tube 32 has higher flexibility, vibration resistance, impact resistance, sealing performance, temperature adaptability, and is lighter, thereby providing a better sealing connection with the first connecting tube 31 and the third connecting tube 33.

[0040] In some embodiments, the fourth connecting tube 34 comprises a rubber tube. Thus, the fourth connecting tube 34 has higher flexibility, vibration resistance, impact resistance, sealing performance, temperature adaptability, and is lighter, thereby providing a better sealing connection with the first connecting tube 31 and the third connecting tube 33.

[0041] It is understandable that the material of the second connecting pipe 32 and the fourth connecting pipe 34 can be the same or different, and the specific choice can be made according to the design requirements.

[0042] Continue reading Figures 1-3In some embodiments, the first connecting pipe 31 and the third connecting pipe 33 are arranged opposite each other along the first direction X, and both the first connecting pipe 31 and the third connecting pipe 33 extend along the second direction Y. The first direction X and the second direction Y intersect, for example, the first direction X and the second direction Y are perpendicular, or the angle between the first direction X and the second direction Y is an acute angle. The dimension of the first connecting pipe 31 along the second direction Y is larger than the dimension of the second connecting pipe 32 along the first direction X, the dimension of the third connecting pipe 33 along the second direction Y is equal to the dimension of the first connecting pipe 31 along the second direction Y, and the dimension of the fourth connecting pipe 34 along the first direction X is equal to the dimension of the second connecting pipe 32 along the first direction X. Thus, the space occupied by the heat dissipation pipe 30 along the first direction X is small, and the dimension of the heat dissipation pipe 30 in the second direction Y is large. In other words, the space occupied by the heat dissipation pipe 30 in the light emission direction is small, and the heat dissipation pipe 30 has a large heat exchange area, thereby improving heat exchange efficiency.

[0043] In some embodiments, the second connecting pipe 32 is constructed in a curved, zigzag, or combination thereof. The fourth connecting pipe 34 is constructed in a curved, zigzag, or combination thereof. The shape of the second connecting pipe 32 may be the same as or different from the shape of the fourth connecting pipe 34. Based on this, the lengths of the first connecting pipe 31 and the second connecting pipe 32 are relatively large, and the space occupied by the second connecting pipe 32 and the fourth connecting pipe 34 in the first direction X is relatively small, allowing the heat dissipation pipe 30 to accommodate more refrigerant in a limited space, thereby improving the heat exchange efficiency of the heat dissipation pipe 30 and thus improving the heat dissipation effect of the vehicle headlight 1.

[0044] Continue reading Figures 1-3 In some embodiments, the housing 10 is provided with a mounting hole 12. The shape of the mounting hole 12 is, for example, triangular, circular, elliptical, quadrilateral, pentagonal, or a combination thereof. The heat sink 40 passes through the mounting hole 12, with a portion of the heat sink 40 extending into the receiving cavity 11 and another portion extending out of the receiving cavity 11. Optionally, the cross-sectional shape of the portion of the heat sink 40 located in the mounting hole 12 is the same as the shape of the mounting hole 12, thereby allowing the mounting hole 12 to be better concealed, reducing the difficulty of sealing, and preventing external debris from entering the receiving cavity 11 through the mounting hole 12.

[0045] Combined Figure 4 Furthermore, the headlight 1 also includes a sealing ring 50. The material of the sealing ring 50 includes at least one of ethylene propylene diene monomer (EPDM) rubber and silicone sealant. The sealing ring 50 is fitted onto the area of ​​the radiator 40 located within the mounting hole 12. In this way, the receiving cavity 11 can be better sealed, thereby protecting the structure within the receiving cavity 11.

[0046] Continue reading Figures 1-4In some embodiments, the housing 10 is provided with a flange 13, which extends from the wall of the mounting hole 12 into the receiving cavity 11. The inner wall of the sealing ring 50 abuts against the heat sink 40, and the outer wall of the sealing ring 50 abuts against the flange 13. In this way, the flange 13 increases the contact area between the housing 10 and the sealing ring 50, thereby improving the sealing effect.

[0047] Optionally, the flange 13 is integrally formed with the outer shell 10, thereby improving structural strength and sealing performance.

[0048] Continue reading Figures 1-4 In some embodiments, the radiator 40 includes a heat exchange plate 42 and a plurality of heat exchange columns 43 disposed on one side surface of the heat exchange plate 42. The heat exchange plate 42 is located within a receiving cavity 11, and a portion of the heat exchange columns 43 is located within the receiving cavity 11, while another portion extends outside the receiving cavity 11. The heat exchange plate 42 and the heat exchange columns 43 may be made of the same or different materials. The material of the heat exchange plate 42 includes, for example, at least one of aluminum and copper. The material of the heat exchange columns 43 includes, for example, at least one of aluminum and copper. Thus, the radiator 40 has a high heat dissipation efficiency.

[0049] Optionally, multiple heat exchange columns 43 are arranged in an array to increase the arrangement density of the heat exchange columns 43, thereby improving the heat dissipation effect.

[0050] Optionally, the axes of the multiple heat exchange columns 43 are parallel to each other, which can improve space utilization and allow more heat exchange columns 43 to be set in a limited space, thereby improving the heat dissipation effect.

[0051] Optionally, the heat exchange plate 42 can be reused as the second mounting plate 41, that is, the same structure serves as both the heat exchange plate 42 and the second mounting plate 41. This can reduce the overall weight of the headlight 1, save materials, and reduce costs.

[0052] Optionally, the heat exchanger also includes a mounting portion 44 protruding from the surface of the heat exchange plate 42 opposite to the light-emitting module 20. The mounting portion 44 is annular, and the annular shape can be circular, elliptical, rectangular, or other desired shapes. Multiple heat exchange columns 43 are located within the annular mounting portion 44. A sealing ring 50 is fitted onto the annular mounting portion 44. This improves the stability of the radiator 40 installation and enhances the sealing effect.
