Description
Technical Field
[0001] This utility model relates to the field of automotive front combination lamp technology, specifically an automotive front lamp module with a narrow light outlet. Background Technology
[0002] With the rapid development of the automotive industry and the increasing demands of consumers for automotive safety, comfort, and aesthetics, the design of automotive front combination lights is facing more and more challenges. Traditional automotive front combination lights, such as bi-xenon LED headlights, typically use lens-type or reflector-type modules as light sources. These modules require an opening size of more than 40mm to meet the needs of light transmission and focusing. However, as modern vehicle design trends towards a more compact and streamlined form, traditional automotive front combination light designs can no longer meet the market's demand for narrower opening sizes. Therefore, we need to propose an automotive headlight module with a narrow light outlet. Utility Model Content
[0003] The purpose of this invention is to provide an automotive headlight module with a narrow light outlet, aiming to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A car headlight module with a narrow light outlet includes a low beam module and a high beam module. The low beam module includes a lens and a low beam reflector disposed on one side of the lens. The high beam module includes a lens and a high beam reflector disposed on one side of the lens. Two sets of high beam reflectors are provided, and the two sets of high beam reflectors are respectively disposed on both sides of the low beam reflector. The high beam reflector and the low beam reflector share a single lens.
[0006] Preferably, one side of the lens is provided with a plurality of light-incident surfaces, and the side of the lens away from the plurality of light-incident surfaces is provided with a light-out surface.
[0007] Preferably, the light-emitting surface includes a first high-beam light-emitting area, a low-beam light-emitting area is provided on one side of the first high-beam light-emitting area, and a second high-beam light-emitting area is provided on the side of the low-beam light-emitting area away from the first high-beam light-emitting area.
[0008] Preferably, it also includes two sets of light-shielding strips, which are respectively placed at the junction of the near-light section and the far-light sections on both sides of the lens.
[0009] Preferably, the length of the lens is ≥150mm and the height is ≤30mm.
[0010] Preferably, the high-beam reflector is configured with a parabolic, parabolic or ellipsoidal shape.
[0011] Preferably, the surfaces of the near beam reflector and the far beam reflector are coated with a high-reflectivity aluminum film.
[0012] Preferably, the near-light reflector is configured with a parabolic, parabolic or ellipsoidal shape.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The low beam function of this invention uses the central area of the lens. Light from the LED, after passing through the low beam reflector, enters from the light-incident surface in the central part behind the lens and then exits through the light-out surface. The high beam function uses the areas on both sides of the lens. Light from the LED, after passing through the high beam reflector, enters from the light-incident surfaces on both sides behind the lens and then exits through the light-out surface. This ensures that while reducing the aperture size, sufficient illumination brightness and uniform light distribution can still be maintained. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 This utility model provides a technical solution:
[0021] A car headlight module with a narrow light outlet includes a low beam module 1 and a high beam module 2. The low beam module 1 includes a lens 101, and a low beam reflector 102 is disposed on one side of the lens 101. The high beam module 2 includes a lens 101 and a high beam reflector 201 disposed on one side of the lens 101. Two sets of high beam reflectors 201 are provided, and the two sets of high beam reflectors 201 are respectively disposed on both sides of the low beam reflector 102. The high beam reflector 201 and the low beam reflector 102 share a single lens 101. The low beam of this invention... The light source from the LED and after passing through the low beam reflector 102, enters through the light-incident surface in the middle part behind the lens 101 and then exits through the light-out surface 4. The high beam function uses the areas on both sides of the lens 101. The light source from the LED and after passing through the high beam reflector 201, enters through the light-incident surface 3 on both sides behind the lens 101 and then exits through the light-out surface 4. This ensures that while reducing the aperture size, sufficient illumination brightness and uniform light distribution can still be maintained.
[0022] Furthermore, one side of the lens 101 is provided with several sets of light-incident surfaces 3, and the side of the lens 101 away from the several sets of light-incident surfaces 3 is provided with a light-out surface 4. The high beam reflector can converge and guide the light in a specific direction. The maximum diameter of the patterned surface of the high beam reflector is greater than or equal to Φ90mm to facilitate light distribution. The focal length F value is generally set in the range of 18mm-40mm. The synergistic effect of the lens 101, the high beam reflector 201, and the low beam reflector 102 is the key to forming a high-quality automotive front combination lamp beam. The lens 101 can further converge and shape the light, making the beam more concentrated and brighter.
[0023] The light-emitting surface 4 includes a first high beam light-emitting area 401, a low beam light-emitting area 402 is provided on one side of the first high beam light-emitting area 401, and a second high beam light-emitting area 403 is provided on the side of the low beam light-emitting area 402 away from the first high beam light-emitting area 401.
[0024] In addition, it also includes two sets of light-shielding strips 5, which are respectively placed at the junction of the near light part and the far light parts on both sides of the lens 101. The light-shielding strips 5 can effectively focus and constrain the light, avoid the scattering and waste of light, which ensures that the light can accurately shine on the road surface in the predetermined direction and improve the lighting effect.
[0025] Furthermore, the length of lens 101 is ≥150mm and the height is ≤30mm, which can ensure that sufficient illumination brightness and uniform light distribution are maintained while reducing the aperture size.
[0026] Furthermore, the high beam reflector 201 is designed with a parabolic, parabolic or ellipsoidal shape. This design can accommodate more reflector bowls to improve the brightness and light distribution of the high beam. The high beam reflector 201 has 5 reflector bowls inside. The reflector bowls are arranged in an alternating manner to reduce interference and overlap between light rays and ensure that the light is reflected evenly and focused onto the lens 101.
[0027] The surfaces of the low beam reflector 102 and the high beam reflector 201 are coated with a high reflectivity aluminum film. The reflectivity of the aluminum film can reach more than 90%, ensuring that most of the light is reflected rather than absorbed. The reflector surfaces are precision polished to eliminate any minor imperfections that may affect the quality of light reflection. The surface roughness after polishing should be less than 0.01μm.
[0028] Furthermore, the low beam reflector 102 is designed with a parabolic shape, and the installation angle of the reflector should be adjusted to be 45 degrees with the optical axis of the lens 101. This design can ensure that the light is effectively reflected and focused onto the lens 101.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
