Integrated matrix lens

Abstract

This utility model relates to an integrated matrix combination lens, including a middle bracket, a rear shell, an LED heat sink, a lens bracket, and a lens. Two PCB boards are mounted on the upper part of the LED heat sink, each containing a low-beam LED. This utility model improves the high and low beam position structure. Two low-beam lenses are located on the left and right sides of the lens, and high-beam lenses are located on the upper and lower sides. The two high-beam lenses are positioned between the two low-beam lenses, forming a cross shape with the two low-beam lenses. The position of the low-beam lenses is raised, thereby increasing the light output angle, preventing glare and eye strain from the low beam, improving light transmittance, and allowing the high beam to reach further without dragging on the ground, resulting in better performance. Furthermore, the upper part of the LED heat sink contains two PCB boards, each containing a low-beam LED, while the upper and lower sides of the lens bracket contain high-beam LEDs. This staggered placement of the low-beam and high-beam LEDs improves heat dissipation.

Description

Technical Field

[0001] This utility model relates to the field of automotive supplies, specifically to an integrated matrix combination lens. Background Technology

[0002] Automotive projectors are lighting devices installed on automobiles for driving illumination. Existing automotive projectors are mainly divided into two types: single-beam projectors and bi-beam projectors. The structure of existing bi-beam projectors is that there are two high beams at the top and one low beam at the bottom. When using this type of projector, it is found that when the low beam is at the bottom, the light output angle is low and can be blocked by the vehicle's trim panel, causing glare and dazzling the eyes. On the other hand, when the two high beams are at the top, they drag on the ground, resulting in poor performance. In addition, the high beam and low beam bulbs are installed in the same heat sink for heat dissipation, which results in poor heat dissipation. Utility Model Content

[0003] To address the aforementioned shortcomings of existing technologies, the technical problem this invention aims to solve is how to improve the performance of lenses for both high and low beams. The specific technical solution is as follows:

[0004] An integrated matrix lens assembly includes a central support, a rear housing, an LED heat sink, a lens holder, and a lens. The rear housing and LED heat sink are installed behind the central support, with the heat sink located above the rear housing. The lens holder is installed in front of the central support, and the lens is installed in front of the lens holder. Two PCBs are mounted on the upper part of the LED heat sink, each containing a low-beam LED. Two low-beam lenses are located on the left and right sides of the lens, with the low-beam lenses corresponding to the low-beam LEDs. High-beam LEDs are installed on the upper and lower sides inside the lens holder, and high-beam lenses are also located on the upper and lower sides of the lens, with the high-beam lenses corresponding to the high-beam LEDs. The two high-beam lenses are located between the two low-beam lenses, and the two high-beam lenses and the two low-beam lenses are arranged in a cross shape.

[0005] As a preferred embodiment of this utility model, a limiting plate is provided behind the lens, and both the high beam lens and the low beam lens are located in front of the limiting plate, with the limiting plate embedded in the lens holder.

[0006] As a preferred embodiment of this utility model, the four corners of the limiting plate avoid the high beam lens and the low beam lens, and the limiting block is installed inside the front of the lens holder by screws. The limiting block presses against the four corners of the limiting plate to prevent the lens from falling out of the lens holder.

[0007] As a preferred embodiment of this utility model, the lens bracket is provided with screw holes on the upper and lower sides, the high beam mounting bracket is fixedly installed inside the lens bracket by screws passing through the screw holes, the high beam lamp bead is fixedly installed in front of the high beam mounting bracket, and the lens bracket is an aluminum alloy bracket.

[0008] As a preferred embodiment of this utility model, a reflector bowl is installed on the top of the PCB board, and the reflector bowl covers the low beam LED.

[0009] As a preferred embodiment of this utility model, an electromagnetic valve for adjusting the low beam path is installed in front of the lamp bead heat sink, and the electromagnetic valve is located inside the lens bracket.

[0010] As a preferred embodiment of this utility model, a fan housing is installed behind the LED heat sink, a fan is installed inside the fan housing, and a fan mesh is installed behind the fan housing.

[0011] Beneficial effects: Compared with the existing technology, this utility model improves the high and low beam position structure. Two low beam lenses are provided on the left and right sides of the lens, and high beam lenses are provided on the top and bottom sides of the lens. The two high beam lenses are located between the two low beam lenses, and the two high beam lenses and the two low beam lenses are distributed in a cross shape. The position of the low beam lenses is raised, thereby increasing the light output angle, preventing glare and blinding from the low beam, improving light transmittance, and allowing the high beam to illuminate further. The high beam also has a better effect by not dragging on the ground. In addition, two PCB boards are installed on the upper part of the lamp bead heat sink, with low beam lamp beads installed on each PCB board, while high beam lamp beads are installed on the top and bottom sides inside the lens bracket. The low beam lamp beads and high beam lamp beads are staggered for heat dissipation, resulting in better heat dissipation. Attached Figure Description

[0018] like Figures 1-3 As shown, the integrated matrix lens assembly includes a central support 1, a rear housing 2, an LED heat sink 3, a lens support 4, and a lens 5.

[0025] (1) Two low beam lenses 51 are provided on the left and right sides of the lens 5, and high beam lenses 52 are provided on the top and bottom sides of the lens 5. The two high beam lenses 52 are located between the two low beam lenses 51. The two high beam lenses 52 and the two low beam lenses 51 are arranged in a cross shape.

The high beam can be projected further and has a better effect without dragging on the ground.

[0026] (2) Two PCB boards 6 are installed on the upper part of the lamp bead heat sink 3. Each PCB board 6 is equipped with a low beam lamp bead. The low beam lamp bead is mainly cooled by the lamp bead heat sink. The high beam lamp bead 7 is installed on the upper and lower sides inside the lens bracket 4. The high beam lamp bead 7 is cooled by the aluminum alloy lens bracket 4.
