Description

Technical Field

[0001] The utility model relates to the technical field of bifocal lenses, in particular to a bifocal lens device for a vehicle lamp. Background Art

[0002] Currently, dual-beam lenses are further improved upon single-beam lenses. They combine two lenses with different functions, one for low beam and one for high beam, to achieve more refined and diverse lighting effects. Generally, the low beam lens in a dual-beam lens is designed to be flatter, producing a wide and uniform light beam, suitable for use in environments with good lighting conditions such as urban roads, providing good road lighting and awareness of the surrounding environment. The high-beam lens, on the other hand, is designed to be more focused and long-range, providing a stronger light beam when long-distance lighting is required, enhancing the driver's ability to identify road conditions in the distance. Through the dual-beam lens design, the vehicle can achieve the best lighting effect in different driving scenarios, ensuring driving safety while improving driving comfort and convenience.

[0003] Since high beams require brighter brightness than low beams, high beams are usually equipped with multiple lamp beads. However, in existing dual-beam lenses, when the high beams illuminate a long distance, the high beam lenses cannot well focus the light of the high beams into one place, thereby affecting the illumination effect. Therefore, a dual-beam lens is needed that can evenly focus the light of multiple high beams into one place. Utility Model Content

[0004] The utility model aims to solve the problems existing in the above-mentioned prior art and provides a dual-beam lens device for vehicle headlights, in which high-beam lenses are arranged on both sides of the low-beam lens and are higher than the low-beam lens. The high-beam lenses form an approximately arc-shaped curve on both sides of the low-beam lamp, thereby converging the light of the high-beam lamp.

[0005] The utility model adopts a technical solution to solve its technical problems: the dual-beam lens device of the vehicle headlight comprises a base plate, on which a low beam headlight and high beam heads located on both sides of the low beam headlight are mounted, a lens plate is provided above the base plate, and the lens plate is provided with a low beam lens area and a high beam lens area corresponding to the low beam headlight and the high beam headlight; the high beam lens area is divided into a middle section area and a tail section area, the middle section area is located between the tail section area and the low beam lens area, and the tail section area is bent toward the middle section area to gather the light of the high beam headlight.

[0006] For further improvement, the lens plate includes a plate body, support feet formed at both ends of the bottom of the plate body and fixed on the base plate, and an illumination space formed between the plate body and the base plate, and the low beam and high beam are located in the illumination space.

[0007] For further improvement, openings for ventilation and heat dissipation are provided at both ends of the irradiation space, and the substrate is made of a material with a thermal conductivity of more than 200W.

[0008] For further improvement, the low beam lens area is provided with a low beam lens, a low beam flat bottom surface provided at the bottom of the low beam lens and covering the low beam lamp, and a low beam arc top surface provided at the top of the low beam lens.

[0009] For further improvement, the middle section is provided with a middle lens, a middle arc bottom surface provided at the bottom of the middle lens, and a middle arc top surface provided at the top of the middle lens. The distance between the middle arc bottom surface and the high beam is greater than the distance between the low beam flat bottom surface and the low beam, and the top of the middle arc top surface is higher than the low beam arc top surface.

[0010] Further improvement: the curvature radius of the top surface of the middle light arc is smaller than the curvature radius of the top surface of the low beam arc.

[0011] For further improvement, the tail section area is provided with a tail section lens, a tail section oblique bottom surface provided at the bottom of the tail section lens and inclined toward the middle section arc bottom surface, and a tail section arc top surface provided at the top of the tail section lens. The distance between the tail section oblique bottom surface and the high beam is greater than the distance between the middle section arc bottom surface and the high beam. The top of the tail section arc top surface is higher than the middle section arc top surface, and the tail section arc top surface is curved toward the middle section area.

[0012] Further improvement, the curvature radius of the top surface of the tail arc is smaller than the curvature radius of the top surface of the middle arc.

[0013] The beneficial effect of the utility model is that the utility model can enable the high-beam lens to gather the light emitted by multiple high-beam lamps into one place, thereby improving the illumination uniformity and light intensity of the high-beam lamps, allowing the driver to better observe the vehicle conditions in the distance, and improving driving safety.
