Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to a dual-lamp, dual-cup LED automotive headlight for retrofitting the internal light source of headlights in the automotive aftermarket. Background Technology

[0002] Currently, most car headlights use halogen bulbs as their light source, which suffers from insufficient brightness and inadequate illumination, especially at night, making it difficult to provide clear road visibility and affecting driving safety. The light source structure and luminous efficiency of traditional halogen headlights limit the improvement of their lighting performance and cannot meet the modern driving demand for high-brightness and high-definition lighting. Utility Model Content

[0003] To address the issues of insufficient brightness and poor lighting performance of existing automotive halogen headlights, a dual-lamp, dual-cup LED automotive headlight is provided. By optimizing the light source structure and supplementary lighting design, the brightness and uniformity of both low and high beams are improved, while the brightness of the center point is enhanced and the problem of stray light on the exterior is reduced.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dual-lamp, dual-cup LED automotive headlight, comprising:

[0005] The housing has a heat sink installed at its lower end, and a fan is installed on the heat sink.

[0006] A mounting base is installed in the inner cavity of the housing. A high beam and low beam lamp plate and a reflector cup covering the high beam and low beam lamp plate are installed on the side of the mounting base. A high beam LED lamp and a low beam LED lamp are installed on the high beam and low beam lamp plate.

[0007] A fill light cup is mounted at the light outlet of the reflector cup; a fill light plate is mounted on the mounting base corresponding to the fill light cup, and a fill light LED is installed on the fill light plate;

[0008] A light cutter is retractably mounted on the fixed base, and its extension and retraction are driven by a solenoid valve; a lens bracket is mounted at the outlet of the housing, and a lens that blocks the opening of the housing is mounted on the lens bracket; a decorative cover is mounted on the outer wall of the housing.

[0009] The high beam and low beam headlight panel integrates high beam LED beads and low beam LED beads. The high beam LED beads are used for high beam mode lighting, and the low beam LED beads are used for low beam mode lighting.

[0010] The reflector cup has a parabolic reflective surface structure, which is used to collect and reflect the light from the high and low beam lamp panels to the lens.

[0011] The fill light cup has a semi-circular structure with a highly reflective coating on its inner wall, which is used to concentrate the light from the fill light LED to enhance the brightness of the center point.

[0012] The light cutter extends and retracts under the drive of the solenoid valve, and is used to retract to release light in high beam mode and extend to block part of the light in low beam mode.

[0013] The lens is a convex lens structure used to refract the light reflected by the reflector.

[0014] The heat sink has an aluminum heat sink fin structure, and the fan is a small axial fan used to reduce the temperature inside the housing.

[0015] The decorative cover is made of plastic or metal and is installed on the outer wall of the housing to block internal stray light and processing defects.

[0016] The specific working principle is as follows:

[0017] 1. Low beam mode: When the car's low beam is turned on, the low beam LEDs on the high beam and low beam headlight panels light up. The light is collected by the reflector and reflected to the lens, and then refracted by the lens to achieve low beam illumination. At this time, the light cutter is in the extended state (blocking part of the light), and the auxiliary light LEDs on the auxiliary light panel light up simultaneously, increasing the brightness of the center point illumination through the auxiliary light cup.

[0018] 2. High Beam Mode: When the car's high beam is turned on, the high beam LEDs on the high and low beam headlight panels light up. At the same time, the solenoid valve drives the light cutter to retract (releasing the blocked light). The light is reflected and refracted by the reflector and lens to achieve high beam illumination. The auxiliary light LEDs on the auxiliary light panel continue to light up, further enhancing the brightness of the center point through the auxiliary light cup.

[0019] The beneficial effects of this utility model are:

[0020] 1. High-power LED bulbs are used instead of halogen bulbs, resulting in higher brightness, longer lifespan, and more comfortable light for human eyes.

[0021] 2. By using a combination of reflector and lens optical structure, combined with a beam cutter to switch between near and far light, efficient directional light projection is achieved;

[0022] 3. Add a fill light panel and fill light cup to provide fill light to the center point, significantly improving the center brightness in both low beam and high beam modes;

[0023] 4. The external decorative cover can block internal stray light and processing defects, improving the overall appearance and texture of the product;

[0024] 5. The heat sink and fan design effectively reduces the operating temperature of the LED beads, ensuring stability during long-term use.

Detailed Implementation

[0030] The present invention will be described in detail below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] like Figure 1 — Figure 3 As shown, the dual-lamp, dual-cup LED automotive headlight of this embodiment has a housing 7 made of aluminum alloy, with a heat sink 10 (aluminum heat sink fin structure) fixed at the lower end. A small axial fan 11 (adjustable speed, used for active cooling) is installed on the heat sink 10. A metal mounting base 9 is fixed to the inner cavity of the housing by screws. A high beam / low beam lamp plate 8 (integrating high-brightness high beam LED beads and low beam LED beads, both of which are single or multiple high-power chips) is installed on one side of the mounting base 9. A reflector cup 5 (parabolic reflective surface, made of aluminum-plated reflector) is covered on the outside of the high beam / low beam lamp plate 8 to focus the light. A semi-circular supplementary light cup 6 (with a white high-reflective coating on the inner wall) is mounted at the light outlet of the reflector cup 5. A supplementary light plate 13 (integrating single or multiple low-power LED beads, used for center supplementary lighting) is installed on the mounting base 9 at the position corresponding to the supplementary light cup 6. A horizontally retractable light cutter 12 (made of light-shielding plastic or thin metal sheet) is also mounted on the mounting base 9 via a guide rail structure. The retraction and extension of the light cutter 12 is controlled by a solenoid valve 3 (which drives the light cutter to retract when energized and extends when de-energized). A lens 1 (convex lens structure, used to refract light to form a clear light pattern) is fixed at the front opening of the housing via a lens bracket 2. A decorative cover 4 (black or body-colored plastic part, covering the internal non-transparent area) is installed on the outer wall of the housing via clips.

[0032] Workflow:

[0033] Low beam mode: When the vehicle circuit is connected to the low beam power supply, the low beam LED beads of the high and low beam headlight panel 8 are lit up. The light is reflected by the reflector cup 5 to the lens 1. The light cutter 12 extends to block stray light at the edge. The supplementary light LED beads of the supplementary light panel 13 are lit up simultaneously, and the brightness of the central area is enhanced by the supplementary light cup 6.

[0034] High beam mode: When the vehicle circuit is connected to the high beam power supply, the high beam LED beads of the high beam and low beam headlight panel 8 are lit. The solenoid valve 3 is energized to drive the light cutter 12 to retract (remove the obstruction). The light is projected through the reflector cup 5 and the lens 1 to form a wide range of high beam. The supplementary light panel 13 continuously supplements the light to enhance the center brightness.

[0035] Heat dissipation: During operation, the fan 11 runs continuously, quickly dissipating the heat generated by the mounting base 9 and LED beads through the heat sink 10 to maintain a stable operating temperature. A fan back cover 14 is installed on the housing 7 to fix the fan 11.

[0036] By adopting the above technical solution, the following technical effects can be achieved:

[0037] 1. High-power LED bulbs are used instead of halogen bulbs, resulting in higher brightness, longer lifespan, and more comfortable light for human eyes.

[0038] 2. By using a combination of reflector and lens optical structure, combined with a beam cutter to switch between near and far light, efficient directional light projection is achieved;

[0039] 3. Add a supplementary light panel and a supplementary light cup to provide supplementary light to the center point, which significantly improves the center brightness in both low beam and high beam modes (at least 5 times that of halogen lamps, and better than 2 times that of similar LED lenses on the market).

[0040] 4. The external decorative cover can block internal stray light and processing defects, improving the overall appearance and texture of the product;

[0041] 5. The heat sink and fan design effectively reduces the operating temperature of the LED beads, ensuring stability during long-term use.
