Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to an LED vehicle light that integrates high beam and low beam functions. Background Technology

[0002] With the development of the automotive industry, vehicle lights not only need to meet basic lighting functions, but also require higher standards in terms of brightness, illumination range, energy efficiency, and compactness. Traditional integrated high / low beam headlights (H4 halogen lamps) suffer from drawbacks such as low brightness, high power consumption, and short lifespan. Existing LED integrated high / low beam headlights mostly use a single or a few LEDs combined with a complex reflector structure to achieve high / low beam switching, but often suffer from problems such as unclear low beam cutoff lines, insufficient high beam brightness, or poor beam pattern. Furthermore, how to efficiently arrange LEDs, optical components, and heat dissipation structures within a limited space is also a technical challenge that urgently needs to be solved in this field. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a vehicle headlight that integrates high and low beams, with a compact structure, high integration, and sufficient high beam brightness.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an integrated high and low beam vehicle headlight, including a lamp body, a lens disposed at the front end of the lamp body, a plug disposed at the rear end of the lamp body, and a light source. The light source includes a first low beam LED, a first high beam LED, and a second high beam LED. The first low beam LED emits light upwards, and the light from the first low beam LED passes through a reflector, a light-blocking plate, and a lens in sequence to form low beam. The first high beam LED emits light forwards, and the light from the first high beam LED passes through a lens to form high beam. The second high beam LED emits light downwards, and the light from the second high beam LED passes through a reflector cup of the lamp assembly to form high beam. The principle of this utility model is as follows: three independent LED light sources, one low beam and two high beams, are integrated into one lamp body through different optical path designs and ultimately projected through the same lens, thereby achieving excellent low beam and high beam illumination effects. The beams of the first high beam LED and the second high beam LED are superimposed to form a more powerful and comprehensive high beam illumination.

[0005] As an improvement, the first low beam LED light and the second high beam LED light are fixed on the first lamp plate, the first high beam LED light is disposed on the second lamp plate, and the first lamp plate and the second lamp plate are perpendicular to each other and electrically connected.

[0006] As an improvement, the light-blocking plate 16 is a steel sheet with a thickness of 0.10~0.14mm, and the light-blocking plate 16 is located between the first low beam LED lamp and the lens.

[0007] As an improvement, the lamp body includes an upper housing and a lower housing, which are fixed together by screws.

[0008] As an improvement, the front end of the upper housing is provided with a lens bracket, the lens is mounted on the lens bracket, and the reflector is located on the upper housing and behind the lens bracket.

[0009] As an improvement, the first light panel is clamped between the upper housing and the lower housing. The upper housing is provided with a first light-transmitting hole corresponding to the first low beam LED, and the lower housing is provided with a second light-transmitting hole corresponding to the second high beam LED.

[0010] As an improvement, a chuck is fitted at the rear of the lamp body, a sealing ring is provided between the chuck and the lamp body, and a retaining ring is provided on the lamp body to prevent the chuck from moving backward.

[0011] As an improvement, the rear of the lamp body is provided with a receiving groove, and a PCB board and a cooling fan are provided in the receiving groove. The plug supplies power to the first lamp board and the cooling fan respectively through the PCB board.

[0012] The beneficial effects of this utility model compared with the prior art are: 1. Three independent LEDs are used to handle different light paths. The low beam forms a standard cutoff line through reflection and light blocking, while the high beam combines direct light and reflection, resulting in high brightness and a wide illumination range. 2. The first low beam LED light and the second high beam LED light are integrated into the first light panel, while the first high beam LED light is integrated into the second light panel perpendicular to the first light panel, which greatly saves internal space and achieves a high degree of integration of complex functions. 3. A special accommodating slot is set at the rear of the lamp body to integrate the cooling fan and PCB board, creating an efficient active cooling airflow channel to ensure the stability and long life of the high-power LED. 4. The upper and lower housings are connected by screws, and the core lamp board is clamped in between, resulting in a stable structure that is easy to produce and maintain; 5. The design of the chuck and sealing ring ensures both ease of installation and a tight seal; 6. An ultra-thin light-blocking plate 16 is used to solve the problem of separation between high and low beams. Attached Figure Description

[0018] like Figure 2 , 3 As shown, the light source includes a first low-beam LED 10, a first high-beam LED 7, and a second high-beam LED 11. The first low-beam LED 10 emits light upwards, and its light beam passes through a reflector 8, a light-blocking plate 16, and a lens 2 in sequence to form low beam. The first high-beam LED 7 emits light forwards, and its light beam passes through the lens 2 to form high beam. The second high-beam LED 11 emits light downwards, and its light beam passes through the reflector cup of the lamp assembly to form high beam. The first low-beam LED 10 and the second high-beam LED 11 are fixed on a first lamp plate 9, and the first high-beam LED 7 is disposed on a second lamp plate 6. The first lamp plate 9 and the second lamp plate 6 are perpendicular to each other and electrically connected.

[0019] like Figure 3 As shown, the light-blocking plate 16 is a steel sheet with a thickness of 0.10~0.14mm. The light-blocking plate 16 is located between the first low beam LED lamp 10 and the lens 2. The use of an ultra-thin light-blocking plate 16 solves the problem of separation between high and low beams.

[0020] like Figure 2 , 3 As shown, the lamp body 1 includes an upper housing 18 and a lower housing 17, which are fixed together by screws for easy assembly and disassembly. The upper housing 18 and lower housing 17 can be made of metal to improve heat dissipation. A lens bracket 5 is provided at the front end of the upper housing 18, and the lens 2 is mounted on the lens bracket 5. The reflector 8 is located on the upper housing 18, behind the lens bracket 5, and fixed to the upper housing 18. The first lamp plate 9 is clamped between the upper housing 18 and the lower housing 17, and the second lamp plate 6 is fixed to the mounting base of the lower housing 17. The upper housing 18 has a first light-transmitting hole corresponding to the first low-beam LED 10, and the lower housing 17 has a second light-transmitting hole corresponding to the second high-beam LED 11. A receiving groove is provided at the rear of the lamp body 1, containing a PCB board 13 and a cooling fan 12. The plug 3 supplies power to the first lamp plate 9 and the cooling fan 12 through the PCB board 13.

[0021] like Figure 2 , 3As shown, a chuck 4 is fitted onto the rear of the lamp body 1 to secure the entire lamp assembly to the vehicle lamp housing. A sealing ring 14 is installed between the chuck 4 and the lamp body 1 to effectively prevent moisture and dust from entering. A retaining ring machined on the lamp body 1 prevents the chuck 4 from slipping backward during vehicle vibrations, ensuring a secure installation.
