Description

Technical Field

[0001] This invention relates to the field of automotive lighting equipment technology, and more particularly to an automotive LED headlight. Background Technology

[0002] Currently, automotive dual-LED headlights on the market use a back-to-back mounting method for the high and low beam LEDs on the heat sink, which causes the high temperature of the two LEDs to concentrate in a small local area; or they use independent high and low beam reflectors, which, due to the back-to-back layout, easily cause deviations in the high and low beam illumination positions and are difficult to adjust.

[0003] In addition, most power modules are designed as separate units, requiring additional installation space; or they are integrated with the lamp assembly, but cannot be disassembled independently from the rear, making later maintenance difficult. Summary of the Invention

[0004] To solve the technical problem, this invention provides an automotive LED headlight.

[0005] The present invention also provides an automotive LED headlight, comprising a lamp holder and a low beam lamp, a high beam lamp, a reflector assembly, a heat dissipation assembly, and a focusing assembly respectively mounted on the lamp holder; the mounting surface of the low beam lamp is horizontally mounted on the lamp holder, and the mounting surface of the high beam lamp is mounted on the lamp holder at an obtuse angle to the mounting surface of the low beam lamp; the focusing assembly is mounted on the light emitting end of the high beam lamp to focus the high beam lamp and adjust the projection angle of the high beam lamp; the reflector assembly is mounted on the light emitting end of the low beam lamp and is used to reflect the projection position of the light from the low beam lamp; the heat dissipation assembly is mounted between the mounting surfaces of the low beam lamp and the high beam lamp.

[0006] Furthermore, the lamp holder is provided with a low beam lamp mounting base connected to the mounting surface of the low beam lamp and a high beam lamp mounting base connected to the mounting surface of the high beam lamp; the low beam lamp mounting base and the high beam lamp mounting base are connected at an obtuse angle.

[0007] Furthermore, the lamp holder has a focusing groove on the side where the high beam is mounted on the high beam mounting bracket. The focusing assembly includes a focusing tube installed in the focusing groove and having a hollow cavity with openings at both ends, a convex lens installed at one end of the hollow cavity, and a mounting plate installed on the outside of the convex lens. The mounting plate is fixedly connected to the edge sidewall of the opening end of the focusing groove at both ends.

[0008] Furthermore, the other open end of the focusing tube is connected to the light emitting end of the high beam; the diameter of the focusing tube gradually increases from the light emitting end of the high beam towards the convex lens.

[0009] Furthermore, the reflector is mounted above the low beam lamp mounting base. The reflector includes a bowl-shaped reflector and a connecting portion extending outward along the edge of the reflector. The lamp holder is provided with a reflective groove corresponding to the connecting portion.

[0010] Furthermore, the heat dissipation assembly includes heat dissipation fins installed on the back side of the low beam lamp mount and the back side of the high beam lamp mount, and a heat dissipation fan installed on the side of the heat dissipation fins away from the low beam lamp mount.

[0011] Furthermore, the lamp holder also includes a lamp mirror mounting bracket mounted on the lamp holder and a lamp mirror mounted on the lamp mirror mounting bracket; the lamp mirror mounting bracket is mounted on the common end of the low beam and high beam light projection.

[0012] Furthermore, the automotive LED headlight also includes a power module detachably mounted on the lamp holder, the power module being mounted on the side of the lamp holder away from the lamp mirror mounting bracket.

[0013] Furthermore, the lamp holder is also equipped with an adjustment assembly for adjusting the projection position and angle of the high beam light; the adjustment assembly includes a light shield mounted on the side of the convex lens away from the high beam light, a fixing plate for fixing the light shield, a mounting ear for mounting the fixing plate, and an adjustment power component for driving the fixing plate to rotate along the mounting ear.

[0014] Furthermore, the fixing plate is provided with connecting ears that connect to the mounting trunnions at both ends, a connecting shaft is provided between the connecting ears, the output end of the adjusting power component is provided with an adjusting rod, and the end of the adjusting rod that connects to the connecting rod is provided with a clamping groove for clamping the connecting shaft.

[0015] The beneficial effects of this invention are: by connecting the mounting surfaces of the low beam and high beam at an obtuse angle and setting heat dissipation components on the back side of both, the mounting surface of the low beam is far away from the mounting surface of the high beam, effectively solving the problem of excessively high temperature in local areas; at the same time, the setting of a focusing component makes it easy to adjust the projection position and angle of the high beam, which is beneficial to the optimization of the light pattern; the structure is relatively simple and easy to apply.

[0035] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0036] like Figures 1-14As shown, the present invention also provides an automotive LED headlight, including a lamp holder 1 and a low beam lamp 2, a high beam lamp 3, a reflector 4, a heat dissipation assembly 5, and a focusing assembly 8 respectively mounted on the lamp holder 1; the mounting surface 21 of the low beam lamp is horizontally mounted on the lamp holder 1, and the mounting surface 31 of the high beam lamp 3 is mounted on the lamp holder 1 at an obtuse angle to the mounting surface 21 of the low beam lamp 2; the focusing assembly 8 is mounted on the light emitting end of the high beam lamp 3 to focus the high beam lamp 3 and adjust the projection angle of the high beam lamp 3; the reflector 4 is mounted on the light emitting end of the low beam lamp 2 and is used to reflect the projection position of the light from the low beam lamp 2; the heat dissipation assembly 5 is mounted between the mounting surface 21 of the low beam lamp 2 and the mounting surface 31 of the high beam lamp 3.

[0037] This invention connects the mounting surfaces 21 of the low beam lamp 2 and 31 of the high beam lamp 3 at an obtuse angle, and provides a heat dissipation component 5 on the back side of both, so that the mounting surface 21 of the low beam lamp 2 is far away from the mounting surface 31 of the high beam lamp 3, effectively solving the problem of excessively high temperature in local areas; at the same time, a focusing component 8 is provided, so that the projection position and angle of the high beam lamp 3 can be easily adjusted, which is beneficial to the optimization of the light pattern; the structure is relatively simple and easy to apply.

[0038] In an optional embodiment, the lamp holder 1 is provided with a low beam lamp mounting base 11 connected to the mounting surface 21 of the low beam lamp 2 and a high beam lamp mounting base 12 connected to the mounting surface 31 of the high beam lamp 3; the low beam lamp mounting base 11 and the high beam lamp mounting base 12 are connected at an obtuse angle. Specifically, the low beam lamp mounting base 11 is provided with a low beam lamp mounting groove for accommodating the mounting surface 21 of the low beam lamp 2, and the high beam lamp mounting base 12 is provided with a high beam lamp mounting groove for accommodating the mounting surface 31 of the high beam lamp 3; this facilitates the fixed installation of the low beam lamp 2 and the high beam lamp 3, and also increases the contact area between the low beam lamp mounting base 11 and the high beam lamp mounting base 12 and the low beam lamp 2 and the high beam lamp 3, which facilitates subsequent heat dissipation and is simple and convenient.

[0039] In an optional embodiment, the lamp holder 1 has a focusing groove 13 on the side of the high beam mounting base 12 where the high beam is mounted. The focusing assembly 8 includes a focusing tube 81 installed in the focusing groove 13 and having openings at both ends, a convex lens 82 installed at one end of the hollow cavity, and a mounting plate 83 installed outside the convex lens 82. The mounting plate 83 is fixedly connected to the edge sidewall of the opening end of the focusing groove 13 at both ends. The other opening end of the focusing tube 81 is connected to the light emitting end of the high beam 3. The diameter of the focusing tube 81 gradually increases from the light emitting end of the high beam 3 towards the convex lens 82. In this embodiment, the focusing tube 81 is provided to facilitate the focusing of the light from the high beam 3 onto the convex lens 82, while the convex lens 82 can further focus and emit the light from the high beam 3. The mounting plate 83 can effectively fix the focusing assembly 8, which is simple and convenient.

[0040] In an optional embodiment, the reflector 4 is mounted above the low beam lamp mounting base 11. The reflector 4 includes a bowl-shaped reflector 41 and a connecting portion 42 extending outward along the edge of the reflector 41. The lamp holder 1 is provided with a reflective groove 14 corresponding to the connecting portion 42.

The connecting portion 42 effectively fixes the reflector 41 to the lamp holder 1.

[0041] In an optional embodiment, the heat dissipation assembly 5 includes heat dissipation fins 51 mounted on the back side of the low beam lamp mount 11 and the back side of the high beam lamp mount 12, and a cooling fan 52 mounted on the side of the heat dissipation fins 51 away from the low beam lamp mount 11. In this embodiment, mounting the heat dissipation fins 51 on the back side of the low beam lamp mount 11 and the back side of the high beam lamp mount 12 can effectively dissipate heat from the low beam lamp mount 11 and the high beam lamp mount 12, while the cooling fan 52 can further increase the heat dissipation efficiency.

[0042] In an optional embodiment, the lamp holder 1 further includes a lamp mirror mounting bracket 61 mounted on the lamp holder 1 and a lamp mirror 62 mounted on the lamp mirror mounting bracket 61; the lamp mirror mounting bracket 61 is mounted at the common end where the low beam lamp 2 and the high beam lamp 3 project light. Specifically, the lamp mirror 62 is bowl-shaped to facilitate the focusing and emission of light from the high beam lamp 3 and the low beam lamp 2.

[0043] In an optional embodiment, the automotive LED headlight further includes a power module 7 detachably mounted on the lamp holder 1, the power module 7 being mounted on the side of the lamp holder 1 away from the lamp mirror mounting bracket 61. This improves the overall integrity of the automotive LED headlight and allows for separate disassembly, facilitating future maintenance and upgrades of the power module 7.

[0044] In an optional embodiment, the lamp holder 1 is further equipped with an adjustment assembly for adjusting the position and angle of the high beam 3. The adjustment assembly includes a light-shielding plate 91 mounted on the side of the convex lens 82 away from the high beam 3, a fixing plate 92 for fixing the light-shielding plate 91, mounting ears 93 for pivoting the fixing plate 92, and an adjustment power component 94 for rotating the fixing plate 92 along the mounting ears 93. The fixing plate 92 is provided with connecting ears 93 that are pivotally connected to the mounting ears 97 at both ends, and a connecting shaft 95 is provided between the connecting ears 93. The output end of the adjustment power component 94 is provided with an adjustment rod 96, and the end of the adjustment rod 96 connected to the connecting rod is provided with a clamping groove for clamping the connecting shaft 95. Specifically, the adjustment power component 94 is a motor, the light-shielding plate 91 is arc-shaped, and the mounting ears 97 are fixedly mounted on the adjustment assembly mounting plate 15. In this embodiment, when the low beam headlights are turned on, the adjusting rod 96 is moved upward by the adjusting power component 94, causing the fixing plate 92 to rotate clockwise around the mounting ear 97, thus raising the angle of the light shield 91 and blocking the light from the high beam headlights. When the high beam headlights are turned on, the adjusting rod 96 is moved downward by the adjusting power component 94, causing the fixing plate 92 to rotate counterclockwise around the mounting ear 97, thus lowering the angle of the light shield 91 and allowing the high beam headlights 3 to project light. By adjusting the components, the projection angle of the high beam headlights 3 can be effectively adjusted, making it convenient and easy for users to use.
