Description

Technical Field

[0001] This utility model relates to LED vehicle lights, and more particularly to an LED vehicle light structure for replacing vehicle lights with lenses. Background Technology

[0002] Automotive headlights commonly use halogen lamps, xenon lamps, and LED lights. Halogen lamps, such as models H1, H7, H11, 9005, 9006, and 9012, and D-series xenon lamps, are generally equipped with lenses. Halogen and xenon lamps have drawbacks such as high energy consumption and short lifespan. With the mature development of LED technology, users are increasingly replacing traditional halogen and xenon lamps with LED headlights. These LED headlights have advantages such as high brightness, low energy consumption, and long lifespan, but their illumination range is relatively short, and their high beam brightness is poor, which significantly affects the driver's experience and negatively impacts driving safety. Utility Model Content

[0003] The purpose of this invention is to provide an LED vehicle light structure with better high-beam illumination, thereby improving lighting performance, driving experience, and safety.

[0004] The LED vehicle lamp structure that replaces the lens-type vehicle lamp described in this utility model includes a lamp housing, a substrate, a heat pipe, and a heat sink mounted on the lamp housing. LED beads are mounted on the substrate. The heat pipe is in contact with the substrate, and one end of the heat pipe is connected to the heat sink, while the other end extends forward of the vehicle and is equipped with a high beam bead and a reflective high beam cup.

A chuck is installed in the middle of the lamp housing, and the other end of the lamp housing is relatively long and thin, extending forward of the car. A substrate is installed on the long end of the lamp housing, and LED beads are installed on the substrate and connected to the LED car light circuit.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0043] This utility model proposes an LED vehicle lamp structure to replace lens-type vehicle lamps.

[0044] Example 1, as Figure 1-6 As shown.

[0045] The LED vehicle lamp structure that replaces the lens-mounted vehicle lamp in this embodiment includes a lamp housing 1, a substrate, a heat pipe 3, and a heat sink 4 mounted on the lamp housing. LED beads 5 are mounted on the substrate. The heat pipe is in contact with the substrate, and one end of the heat pipe is connected to the heat sink, while the other end extends forward of the vehicle and is equipped with a high beam bead 6 and a reflective high beam cup 7. The high beam cup covers the high beam bead and reflects light forward of the vehicle.

[0046] like Figure 1 , 2 As shown, the left end of the lamp housing is larger and contains a heat sink. A chuck is installed in the middle of the lamp housing. The right end of the lamp housing is relatively long and thin, extending forward of the car. A substrate is installed on the long and thin end of the lamp housing. LED beads are installed on the substrate and connected to the LED headlight circuit. When the LED beads emit light, they provide illumination through the car's headlight assembly and transfer heat to the heat pipe, which then transfers the heat to the heat sink. When the car needs to switch to high beam while driving, in addition to using the high beam chip group or light shield of the LED beads to provide long beam, the high beam beads at the front end of the heat pipe can also be used. After the high beam beads are powered on and emit light, the light will be reflected by the high beam cup to a position further forward of the car, forming a high beam effect.

[0047] The LED vehicle light structure includes a main substrate 21 for mounting LED chips 5 and a secondary substrate 22 for mounting high beam chips 6. The main substrate is mounted on the lamp housing 1 and contacts the middle of the heat pipe 3. The secondary substrate is fixedly mounted to the end of the heat pipe. The main substrate and the secondary substrate are electrically connected through conductive elements (such as wires, not shown). Dividing the substrate into two parts makes it easier to set the orientation of different LED chips and better accommodates the arrangement of heat pipes with different shapes. Figure 3 , 4As shown, the end of the heat pipe 3 is inclined upward and a sub-substrate 22 is installed thereon. The sub-substrate 22 and the high beam cup 7 are installed on the top surface of the end of the heat pipe, so that the high beam can form a suitable angle and distance after being reflected by the high beam cup. At the same time, the end of the heat pipe 3 is bent to control the horizontal height of the high beam beads and the high beam cup, so as to avoid obstructing the LED beads behind it. It can also extend the length of the heat pipe and improve the heat dissipation effect.

[0048] In existing vehicles that use LED headlights instead of xenon headlights, the compatibility of LED headlights is severely limited due to the varying sizes and shapes of headlight lenses across different vehicles, making it impossible to install LED headlights on many cars. Therefore, the LED headlight structure in this embodiment is as follows: Figure 1-4 As shown, a chuck 8 is mounted in the middle of the lamp housing 1. The heat sink 4 is mounted on the lamp housing on one side of the chuck. The lamp housing on the other side of the chuck is elongated and has an adjustment groove 11. The heat pipe 3 includes a fixed pipe 31 and an adjustment pipe 32. The fixed pipe is fixedly installed and in contact with the main substrate 21. The adjustment pipe is movably installed in the adjustment groove and in contact with the fixed pipe, so that the adjustment pipe can be adjusted along the front-rear direction of the vehicle. At the same time, the sub-sub-substrate 22 and its high beam bulb 6 and high beam cup 7 are fixedly installed at the end of the adjustment pipe, so that the high beam bulb can be adjusted as the adjustment pipe moves. This allows for adjustment of the high beam illumination range and better adaptability to the needs of different types of vehicle assembly modifications. Furthermore, as... Figure 5 As shown, the adjustment groove 11 of the lamp housing 1 is provided with an opening groove 12 extending to the outer wall of the lamp housing. The fixing tube 31 and the adjustment tube 32 are both set in the adjustment groove. The main substrate 21 is set in the opening groove and contacts the fixing tube. The plate of the main substrate 21 is vertically set. LED beads 5 are installed on both sides of the main substrate. This can improve the stability of the movement of the adjustment tube and ensure its continuous and stable contact with the fixing tube, ensuring the heat transfer and heat dissipation required. At the same time, it can make the overall structure more compact and ensure the lighting effect.

[0049] The regulating tube can be fixed and adjusted using an interference fit, or it can be fixed in the desired position using different fixing components, or as... Figure 5 , 6As shown, the lamp housing 1 includes two opposing shell plates 13. The opposite sides of the two shell plates have recessed grooves forming an adjustment groove 11. A clamping assembly 9 clamps the two shell plates and fixes the adjustment tube 32 within the adjustment groove. The clamping assembly clamps the two shell plates, which in turn clamp the adjustment tube within the adjustment groove, thus fixing the adjustment to the desired position. When the position of the adjustment tube needs to be changed, the clamping assembly is released, releasing the lock on the adjustment tube by the two shell plates, thereby satisfying the adjustment requirement. The two shell plates can be two interconnected parts of the entire lamp housing, or they can simply extend from the lamp housing, for example, two slender rods extending from the middle of the lamp housing as shell plates for setting the adjustment groove, and then clamped by the clamping assembly. The specific configuration can be set as needed to meet different production, installation, and usage requirements. In addition, the clamping assembly can be a screw to fix the two shell pieces by a screw bracket, or it can be a sleeve that fits over the shell pieces, or other devices capable of clamping the shell pieces; or as in this embodiment. Figure 2 , 5 As shown in Figure 6, the clamping assembly 9 includes two clamping shells 91 disposed outside the lamp housing 1. The two clamping shells are fixedly connected by fasteners 92 (such as screws) and clamp the two shell pieces 13. This not only facilitates assembly, disassembly, and replacement, but also improves the fixing strength. Furthermore, by changing the size and shape of the clamping shells, all or part of the shell pieces, substrate, and heat-conducting pipes can be covered internally to form protection. In addition, the outer wall of the lamp housing 1 has a positioning groove 14 parallel to the adjustment groove 11. The clamping shell 91 is provided with a limiting block 93 disposed in the positioning groove and moving along the positioning groove. This facilitates positioning for installation and also improves the overall connection strength. Moreover, the clamping shell 91 can be integrally disposed with the reflector cup, which not only reduces production costs but also ensures the fitting accuracy between components and guarantees the lighting effect.

[0050] Example 2, as Figure 7 As shown.

[0051] The LED vehicle light structure in this embodiment, which replaces the lens-type vehicle light, includes a heat pipe 3. The end of the heat pipe is inclined upward and mounted on a sub-substrate 22. The main substrate 21 is horizontally arranged and mounted on the top surface of the heat pipe. The rest is the same as in Embodiment 1. This type of LED vehicle light has a relatively simple structure, low cost, and can effectively meet the illumination requirements of high beams.

[0052] Example 3, as Figure 8 As shown.

[0053] The LED vehicle light structure of this embodiment, which replaces the lens-type vehicle light, includes a heat pipe 3. The heat pipe includes a horizontal section 33, an inclined section 34, and a curved section 35 arranged sequentially. The horizontal section is horizontally arranged along the front-rear direction of the vehicle and connected to the heat sink 4. The inclined section is inclined downwards, and the main substrate 21 is mounted on the top surface of the inclined section. One LED bead 5 is mounted on the main substrate. The curved section is curved and its end is inclined upwards, where a sub-substrate 22 is mounted. The rest is the same as in Embodiment 1. This type of LED vehicle light not only has a simple structure but also allows the LED bead to form a specific angle to achieve the required lighting effect; and the lighting requirements can be met with a single LED bead.

[0054] Example 4, as Figure 9 As shown.

[0055] The LED headlight structure of this embodiment, which replaces the lens-mounted headlight, includes a heat pipe 3 and two main substrates 21 on which LED beads 5 are mounted. The two main substrates are respectively mounted on the top and bottom surfaces of the heat pipe, and the end of the heat pipe is inclined upward and mounted on a sub-substrate 22; the rest is the same as in Embodiment 1. By setting LED beads on the upper and lower sides, the lighting range and lighting effect can be better guaranteed, and the possibility of dark areas can be reduced.

[0056] Example 5, as Figure 10 As shown.

[0057] In this embodiment, the LED headlight structure, which replaces the lens-mounted headlight, has a main substrate 21 mounted obliquely on both the left and right sides of the fixing tube 31, with LED beads 5 mounted on each of the two main substrates; the rest is the same as in Embodiment 1. By setting the LED beads on the left and right sides, the lighting range and lighting effect can be better guaranteed, and the possibility of dark areas can be reduced.

[0058] Example 6, as Figure 11 As shown.

[0059] In this embodiment, the LED headlight structure, which replaces the lens-mounted headlight, has the sub-substrate 22 and the high beam cup 7 mounted at the bottom of the heat pipe 3; the rest is the same as in Embodiment 1. This achieves a specific lighting effect.

[0060] Example 7, as Figure 12 As shown.

[0061] The LED vehicle light structure in this embodiment, which replaces the lens-mounted headlight, has two fixed tubes 31. These two tubes are arranged along the left-right direction of the vehicle with a gap between adjacent sides. The main substrate 21 is mounted at the gap between the two fixed tubes. The adjusting tube 32 can be horizontally positioned; the rest is the same as in Embodiment 1. This type of LED vehicle light has better heat conduction and dissipation effects, and can reduce the manufacturing difficulty and cost of the adjusting tube.

[0062] Example 8, as Figure 13 As shown.

[0063] In this embodiment, the LED headlight structure that replaces the lens headlight has a direct-light bulb 10 installed at the end of the heat pipe 3, with the light-emitting surface of the direct-light bulb facing the front of the car.

[0064] like Figure 13 As shown, a high beam LED is installed on the top surface near the end of the right side of the heat pipe, and a direct-beam LED is installed at the end of the right side. The direct-beam LED is vertically positioned. When the car needs to use high beams while driving, the LED LEDs can form the first high beam through the car's headlight assembly. The high beam reflector reflects the light from the high beam LEDs to form the second high beam. The direct-beam LED illuminates the front directly to form the third high beam. These three high beams combine to form the final high beam effect, thereby greatly improving the intensity and range of high beam lighting and further meeting lighting needs.

[0065] In the described LED vehicle light structure, the direct-light bulb 10 can be directly mounted on the sub-substrate 22. However, the sub-substrate has a complex structure and high production cost. Therefore, a separate direct-light substrate 20 can be provided. The direct-light substrate is mounted at the end of the heat pipe 3 and connected to the sub-substrate 22. The direct-light bulb 10 is mounted on the direct-light substrate, which facilitates the arrangement and installation of components. In addition, the lamp housing 1 and the substrate have elongated clearance holes 30 on the opposite side of the fastener 92 for the fastener to pass through. This allows the clamping assembly to move relative to the lamp housing. On the other hand, the elongated clearance holes can also limit the travel of the direct-light bulb.

[0066] Example 9, as Figure 14-16 As shown.

[0067] In this embodiment, the LED headlight structure, which replaces the lens-mounted headlight, integrates the heat sink 4 onto the headlight housing 1. One end of the headlight housing serves as the heat sink, and its outer wall is provided with heat dissipation fins. Adjacent heat dissipation fins are connected to internal heat dissipation grooves, ensuring airflow during the operation of the internal cooling fan. Additionally, as... Figure 15 As shown, one end of the lamp housing 1 is a heat sink 4, and a mounting cavity is provided on the side of the heat sink facing away from the direct-light lamp bead 10. The cooling fan 40 and the terminal circuit board 50 are both installed in the mounting cavity. There is also a back cover 60 covering the side of the heat sink, which ensures the installation of the cooling fan and the terminal, and protects them and improves the aesthetics. In addition, the clamping assembly 9 and the lamp housing 1 have a positioning hole that connects to the adjustment groove 11 and points to the adjustment tube 32. A positioning screw 70 is installed at the positioning hole. The end of the positioning screw abuts and presses against the adjustment tube, thereby fixing the adjustment tube in a specific position and preventing it from moving accidentally and affecting the lighting effect and working stability.

[0068] In other embodiments, different LED headlight structures can also be appropriately selected, such as... Figure 17 As shown, this LED vehicle headlight structure is equipped with LED bulbs and high beam bulbs, and the heat sink is integrated into the headlight housing; for example... Figure 18 As shown, its counterpart to Embodiment 1 adds direct-light LED beads. The above description is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the utility model concept and utilizing the content of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
