Description

Technical Field

[0001] This utility model relates to LED vehicle lights, and in particular to an LED vehicle light structure with direct high beam. Background Technology

[0002] Automotive headlights commonly use halogen lamps, xenon lamps, and LED lights. Many halogen and xenon lamps are equipped with lenses or reflectors to reflect light and create the desired beam angle. However, with the maturation of LED technology, users are increasingly replacing traditional halogen and xenon lamps with LED lights. These LED lights offer advantages such as high brightness, low energy consumption, and long lifespan. However, existing LED lights have a relatively short illumination range and poor high-beam brightness, which is detrimental to driver operation and negatively impacts driving safety. Utility Model Content

[0003] The purpose of this invention is to provide a direct-beam LED vehicle headlight structure with better high-beam illumination, thereby improving the lighting effect, driving experience and safety.

[0004] The direct-light LED vehicle lamp structure of 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 connected to the direct-light beads. The direct-light beads are mounted at the end of the heat pipe or at the end of the lamp housing and are in contact with the heat pipe. The light-emitting surface of the direct-light beads faces forward of the vehicle.

[0005] The direct-beam LED vehicle light structure of this utility model has a larger lamp housing at one end with a heat sink, a chuck installed in the middle of the lamp housing, and a thinner, longer end that extends forward towards the car. A substrate is mounted on the thinner end of the lamp housing, with one end extending into and contacting the heat sink. An LED bead is mounted on the other end of the substrate and connected to the LED vehicle light circuit. When the LED bead emits light, it illuminates the car's headlight assembly. The heat generated by the light is transferred to the heat sink through the substrate, and further transferred to the heat pipe before being transferred to the heat sink, thereby improving heat dissipation efficiency. When the car needs to switch to high beam while driving, in addition to using the LED bead chipset to form high beam, the direct-beam LED can also be controlled to illuminate a position further forward of the car, thus forming high beam. Combining the high beam of the LED bead, a wider range and higher brightness high beam illumination effect can be formed, which can effectively improve driving convenience and the driver's driving experience, as well as driving safety.

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. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0031] This utility model proposes a direct-projection LED vehicle light structure.

[0032] Example 1, as Figure 1-3 As shown.

[0033] The direct-light LED vehicle lamp structure of this embodiment includes a lamp housing 1, a substrate 2, a heat pipe 3, and a heat sink 4 mounted on the lamp housing, and LED beads 5 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, and the other end extends forward of the vehicle and is equipped with a direct-light bead 6, with the light-emitting surface of the direct-light bead facing forward of the vehicle.

[0034] like Figure 1 As shown, a chuck 7 is installed in the middle of the lamp housing, which is used to fix the LED car light onto the car's headlight assembly. The lamp housing is located on the left side of the chuck, facing the car's cab. It has a larger diameter and is used to install the heat sink inside. The lamp housing is located on the right side of the chuck, facing the front of the car. It has a relatively long and thin shape and extends forward. The substrate and heat pipe that are in contact with each other are installed at the long and thin end of the lamp housing, and one end of each of them extends into the heat sink and contacts the heat sink. The other end of the substrate is equipped with an LED lamp bead and connected to the LED car light circuit. The other end of the heat pipe continues to extend forward and is equipped with a direct-beam LED bead. When in operation, the LED beads emit light and provide illumination through the car's headlight assembly. The heat generated by the light emission is transferred to the heat sink through the substrate, and even more so to the heat pipe, and then from the heat pipe to the heat sink, thereby improving heat dissipation efficiency. When the car needs to switch to high beam while driving, in addition to using the LED bead chipset to generate high beam, the direct-beam LED at the front end of the heat pipe can also be controlled to operate. The light-emitting surface of the direct-beam LED is set facing forward of the car. In this embodiment, the direct-beam LED is set vertically, and the light emitted by the direct-beam LED directly illuminates a position further forward of the car, thereby generating high beam. Combining the high beam of the LED beads, a wider range and higher brightness high beam illumination effect can be achieved.

[0035] The described direct-beam LED vehicle light structure allows the direct-beam LED chips to be connected to a substrate via conductive elements (such as wires), and their operation to be controlled by a control circuit on the substrate. Alternatively, it can be... Figure 1-3 As shown, a direct-light substrate 8 is installed at the end of the heat pipe 3, and the direct-light LED 6 is installed on the front side of the direct-light substrate. The direct-light substrate allows for more accurate and safer control of the direct-light LED, and also better adapts to the arrangement of heat pipes with different shapes. The substrate and the direct-light substrate can be electrically connected through conductive elements to ensure power transmission. In addition, the end of the heat pipe 3 is bent to control the horizontal height of the direct-light LED. Depending on the situation, the horizontal height of the direct-light LED can be made to be consistent with or staggered with the horizontal height of the LEDs behind it, thereby improving the lighting brightness while achieving the desired lighting effect. The bent end also increases the length of the heat pipe, which is beneficial for improving heat dissipation.

[0036] Because different cars have different headlight assembly structures, and existing LED headlights are difficult to adapt to different car models, many cars cannot be effectively modified, which greatly limits the use of LED headlights. To address this, an adjustment groove 11 can be provided on the lamp housing 1. The direction of the adjustment groove is along the front-to-back direction of the car, i.e., the same as the direction of the substrate in the figure. The heat-conducting pipe 3 is movably mounted on the adjustment groove, and an adjustment housing 9 is mounted on the lamp housing 1 and can move back and forth. The heat-conducting pipe and the adjustment housing are fixedly connected, and the adjustment housing is fixedly connected to the lamp housing by fasteners 10. When the fasteners are loosened, the adjustment housing can move the heat-conducting pipe and its direct-beam LED along the adjustment groove, thereby changing the position of the direct-beam LED. This can adjust the high beam illumination range and better adapt to the modification needs of different types of car assemblies. Figure 2 As shown, the adjusting housing 9 includes two housing pieces clamped and fixed on the lamp housing 1. The fastener 10 is a fastening screw. The two housing pieces are clamped and fixed on the lamp housing by tightening the fastening screw. The lamp housing and the base plate 2 have clearance holes 12 at the positions opposite to the fastening screw, allowing the adjusting housing to move relative to the lamp housing. On the other hand, the clearance holes can be used to limit the travel of the direct-light lamp beads.

[0037] Example 2, as Figure 4-6 As shown.

[0038] In this embodiment of the direct-light LED vehicle lamp structure, the heat pipe 3 includes a fixed pipe 31 and an adjusting pipe 32. The fixed pipe is fixedly installed and in contact with the substrate 2. The adjusting pipe is in contact with the fixed pipe and is movably installed on the adjusting groove 11 of the lamp housing 1. One end of the fixed pipe 31 is connected to the heat sink 4, and one end of the adjusting pipe extends forward of the vehicle and is equipped with a direct-light bulb 6. This can improve the heat dissipation efficiency by adding a heat pipe, and the fixed pipe is more stably connected to the heat sink, thereby ensuring that the heat is accurately and quickly transferred to the heat sink. At the same time, the adjusting pipe ensures the adjustment effect of the direct-light bulb.

[0039] In addition, the outer wall of the lamp housing 1 has a positioning groove 13 parallel to the adjustment groove 11. The adjustment housing 9 has a limiting block 91 that is set in the positioning groove and moves along the positioning groove. This can also effectively limit the movement of the adjustment housing and the direct-light lamp. Furthermore, the adjustment housing 9 and the lamp housing 1 have positioning holes that connect to the adjustment groove 11 and point to the adjustment tube 32. A positioning screw 20 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.

[0040] Example 3, as Figure 7-9 As shown.

[0041] In this embodiment of the direct-beam LED vehicle light structure, the heat sink 4 is integrally mounted on the lamp housing 1. One end of the lamp housing is the heat sink, and the outer wall of this end is provided with heat dissipation fins. Adjacent heat dissipation fins are connected to internal heat dissipation grooves to ensure airflow under the operation of the internal cooling fan. Additionally, as... Figure 9 As shown, one end of the lamp housing 1 is a heat sink 4, and the side of the heat sink facing away from the direct-light lamp bead 6 is provided with a mounting cavity. The cooling fan 30 and the terminal circuit board 40 are both installed in the mounting cavity. There is also a back cover 50 covering the side of the heat sink, so as to ensure the installation needs of the cooling fan and the terminal, and to protect them and improve the aesthetics.

[0042] Example 4, as Figure 10 As shown.

[0043] In this embodiment of the direct-light LED vehicle lamp structure, the direct-light substrate 8 is rotatably connected to the lamp housing 1, and during rotation, the bottom of the direct-light substrate can continuously contact the end of the heat-conducting pipe 3. For example, an arc-shaped groove is provided on the heat-conducting pipe, and the arc of the arc-shaped groove is consistent with the rotation radius of the direct-light substrate, thereby ensuring contact and heat transfer between the direct-light substrate and the heat-conducting pipe. This allows for easier adjustment of the angle of the direct-light substrate to meet the needs of different vehicle models and usage.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
