Detailed Implementation

[0021] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] The embodiments provided by this utility model are as follows: Figures 1-4 As shown, an adjustable light distance automotive lens includes a housing 10, which includes a bottom shell 11 and a lens bracket 12. The lens bracket 12 is fixedly mounted on the front end of the bottom shell 11, and a lens 20 is fixedly mounted on the front end of the lens bracket 12. A reflector 30 is fixedly mounted on the bottom shell 11, and a first light-emitting LED 40 is fixedly mounted on the top of the bottom shell 11. The reflector 30 is positioned above the first light-emitting LED 40. A first placement plate 50 is vertically fixedly mounted on the inner surface of the top of the lens bracket 12, and the first placement plate 50 is positioned above the first light-emitting LED 40. A second light-emitting LED 60 is horizontally fixedly mounted on the front end of the first placement plate 50. A connecting part 70 is fixedly mounted on the rear end of the bottom shell 11, and a radiator 80 with a fan at the rear is fixedly mounted on the rear end of the connecting part 70. A light-shielding component 90 is fixedly mounted on the bottom shell 11, which is used to adjust the amount of light emitted by the first light-emitting LED 40 passing through the lens 20. The light-shielding component 90 is positioned below the first placement plate 50.

[0023] Lens 20 acts as a beam convergent, efficiently converting scattered light into a directional beam, reducing light loss, and increasing illumination brightness several times over.

[0024] The light emitted by the first light-emitting lamp 40 passes through the reflector 30 and is emitted towards the lens 20 through the gap between the first placement plate 50 and the light-shielding assembly 90. The light emitted by the second light-emitting lamp 60 passes directly through the lens 20 and is emitted outward.

[0025] In low beam mode, the light shielding component 90 is not activated. Only the light emitted by the first light-emitting bulb 40 is refracted by the reflector cup 30, and only a small portion of the light shines into the lens 20 through the gap between the first placement plate 50 and the light shielding component 90. Most of the light is blocked by the light shielding component 90.

[0026] In high beam mode, the light shield 90 moves downward, and the gap between the light shield 90 and the first placement plate 50 in the vertical direction increases. More light emitted by the first light-emitting beads 40 is refracted by the reflector cup 30 and then shines along the gap between the light shield 90 and the first placement plate 50 onto the lens 20, thereby enhancing the illumination range of the device and improving the lighting effect.

[0027] The first LED bead 40 and the second LED bead 60 are preferably made of LED chips, which have the advantages of high efficiency and energy saving, ultra-long life and green safety.

[0028] Preferably, the light-shielding component 90 includes a base 91, which is fixedly mounted on the bottom shell 11. A solenoid valve 92 is fixedly mounted on the base 91. An arc-shaped light-shielding plate 93 is fixedly mounted on the top of the solenoid valve 92. The light-shielding plate 93 is located between the first light-emitting lamp bead 40 and the first placement plate 50, and is located below the first placement plate 50.

[0029] In high beam mode, the solenoid valve 92 is activated, which drives the light shield 93 to press down. The gap between the light shield 93 and the first placement plate 50 in the vertical direction increases, and more light emitted by the first light-emitting beads 40 is refracted by the reflector cup 30 and then shines along the gap between the light shield 93 and the first placement plate 50 onto the lens 20, making the illumination range of the device wider and the lighting effect better.

[0030] It should be noted that the function of the solenoid valve 92 is to drive the light-shielding plate 93 to press down and reset. Its structure belongs to the prior art, so it will not be described in detail in this application.

[0031] Preferably, the bottom shell 11 has through mounting grooves 140 at both ends, and the two ends of the base 91 are respectively installed on the two mounting grooves 140. This arrangement makes it convenient for staff to disassemble and install the light-shielding component 90, and can be replaced in time when the solenoid valve 92 malfunctions. The operation is simple.

[0032] Preferably, the lens 20 covers the front end of the lens bracket 12. The lens 20 includes an upper lens 21 and a lower lens 22. Both the upper lens 21 and the lower lens 22 are fixedly mounted on the lens bracket 12 and are fixedly connected. The upper lens 21 is located directly in front of the second light-emitting lamp bead 60. Both the upper lens 21 and the lower lens 22 are arc-shaped structures, and the lower lens 22 protrudes forward relative to the upper lens 21.

[0033] Preferably, the housing 10 also includes a top housing 13, which is fixedly disposed above the bottom housing 11. The front end of the top housing 13 is fixedly connected to the rear end of the lens bracket 12. The top housing 13 is provided with a plurality of heat dissipation holes 100. The top housing 13 can block the light emitted by the first light-emitting lamp bead 40 from shining upward along the front end of the reflector cup 30. Providing heat dissipation holes 100 can improve the heat dissipation efficiency inside the housing 10 and prevent the first light-emitting lamp bead 40 from being damaged due to excessive internal temperature of the housing 10.

[0034] Preferably, a second placement plate 110 is horizontally fixedly disposed at the bottom of the first placement plate 50, and an arc-shaped focusing plate 120 is fixedly disposed on the second placement plate 110. The focusing plate 120 is disposed around the second light-emitting lamp bead 60, and its arc-shaped surface is disposed above the second light-emitting lamp bead 60. The focusing plate 120 guides the light emitted by the second light-emitting lamp bead 60 to converge toward the center of the lens 20 by refraction, thereby improving the high beam illumination effect of the device.

[0035] Preferably, the bottom of the bottom shell 11 is provided with a plurality of heat dissipation grooves 130, which are located directly below the first light-emitting lamp bead 40. The heat dissipation grooves 130 can improve the heat dissipation efficiency of the bottom of the first light-emitting lamp bead 40 and prevent the first light-emitting lamp bead 40 from being damaged due to excessive temperature.

[0036] The bottom shell 11 is preferably made of aluminum alloy, which has advantages such as low cost, easy processing, lightweight and good thermal conductivity. Its surface is anodized to improve corrosion resistance and nickel-plated to enhance oxidation resistance. Several heat dissipation slots 130 can be distributed in a fin shape to maximize the heat dissipation area.

[0037] Preferably, a fixing chuck 150 is fixedly sleeved on the connecting part 70, and a plurality of mounting holes 160 are evenly opened on the fixing chuck 150. This arrangement facilitates the installation of the device by the staff and improves work efficiency.

[0038] This utility model discloses an adjustable light distance automotive lens. A lens 20 is fixedly mounted at the front end of a lens bracket 12. A reflector 30 is fixedly mounted on a base shell 11. A first light-emitting LED 40 is fixedly mounted on the top of the base shell 11. A first placement plate 50 is vertically fixedly mounted on the inner surface of the top of the lens bracket 12. A second light-emitting LED 60 is horizontally fixedly mounted at the front end of the first placement plate 50. A light-shielding component 90 is fixedly mounted on the base shell 11. The light-shielding component 90 is used to adjust the amount of light emitted by the first light-emitting LED 40 passing through the lens 20. The light-shielding component 90 is positioned below the first placement plate 50, enabling the adjustable light distance automotive lens to form both high beam and low beam lighting modes. In high beam mode, the illumination range is wider and the lighting effect is better.
