Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a corner light module that does not require adjustment. Background Technology

[0002] Corner lights, often referred to as static cornering lights, are lighting fixtures specifically designed to provide illumination at corners when a vehicle is turning. Corner lights typically consist of a light source, reflector, electrical interface, and housing. With the increasing emphasis on streamlined and intelligent automotive design, the available space in headlight assemblies has been drastically reduced, leading to miniaturization of corner light modules. This has further reduced the space available for the internal components of the corner lights. In one existing technical solution, the core of the corner light module is to reflect the light source through an internal reflector. The depth of the reflector directly determines the light focusing efficiency, light pattern accuracy, and illumination distance. A shallow depth design cannot simultaneously meet the three core requirements of "no glare", "long light path" and "uniform light distribution". Therefore, the reflector needs to be deeper, which cannot meet the needs of small spaces. Another solution uses a lens module. Typically, lenses have a small beam angle, and using a single lens is insufficient to cover blind spots when a car is turning. A built-in dimming mechanism is needed to adjust the beam angle. The dimming mechanism generally includes a drive module, a sensing module, and a control module. By sensing the vehicle condition and the current beam angle, it controls the received signal and drives the motor to adjust the lens position, thereby changing the beam angle. The dimming mechanism is too expensive, and changing the lens position will change the appearance of the headlight, making the light-emitting surface non-parallel to the front of the car, which affects the appearance.

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.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0018] In a preferred embodiment of this utility model, an adjustment-free corner light module is provided, characterized in that, as Figure 1 As shown, it includes: heat sink; Printed circuit board 2 is mounted on the upper surface of the heat sink, and an illumination module 21 is provided on the printed circuit board 2. The reflector is mounted on the upper surface of the heat sink and fixed above the printed circuit board 2. A lens module is mounted on the side of the heat sink. The lens module includes a lens bracket 4 and a lens 41. By adjusting the reflection angle of the reflector bowl, the light output by the lighting module 21 passes through the lens module.

[0019] In a preferred embodiment, the lens 41 is small in size, with its length, width and height typically between 8 mm and 15 mm.

[0020] In a preferred embodiment, the heat sink includes: Positioning plate 1, the upper surface of positioning plate 1 serves as the upper surface of the heat sink, and the upper surface of positioning plate 1 is vertically provided with a number of first positioning holes 11, a number of first positioning posts 12 and a number of positioning rods, and the lower side of positioning plate 1 is provided with a number of second positioning holes 13, and the outer side of each positioning rod is vertically provided with a number of second positioning posts 14. The heat sink includes a plurality of first heat sinks 15 and a plurality of second heat sinks 16. The first heat sinks 15 are vertically mounted on the upper surface of the positioning plate 1, and the second heat sinks 16 are vertically mounted on the lower surface of the positioning plate 1. The surface area of ​​the first heat sinks 15 is smaller than the surface area of ​​the second heat sinks 16.

[0021] In a preferred embodiment, the positioning plate 1 is the positioning base plate of the corner lamp module, providing positioning for the installation of various components of the corner lamp module. Its upper surface is a rectangular surface. The printed circuit board 2 and the reflector are mounted parallel to each other on the positioning plate 1, and the lens module is mounted parallel to the positioning rod. Figure 2 As shown, the components are installed compactly, achieving miniaturization of the corner light module.

[0022] Specifically, the first heat sink 15 is located on one side above the positioning plate 1. Each first heat sink 15 is vertically installed parallel to the longer side of the rectangular surface, and one end of each first heat sink 15 is aligned with the shorter end of the rectangular surface.

[0023] In this embodiment, there are two positioning rods. The positioning rods are located at the other end relative to the mounting side of the first heat sink, and the two positioning rods are symmetrically arranged with respect to the central axis of the shorter side of the rectangular surface.

[0024] In this embodiment, there are two first positioning posts 12, which are located between the first heat sink and the positioning rod and are aligned with each positioning rod respectively.

[0025] In this embodiment, there are two first positioning holes 11. The first positioning holes 11 are located between the first heat sink 15 and the first positioning post 12 and are aligned with each positioning post.

[0026] In this embodiment, there are two second positioning posts 14, which are vertically arranged on the upper side of the positioning rod and aligned in a parallel position.

[0027] In this embodiment, two fixing mechanisms are provided below the positioning plate 1 for the positioning rod, and each fixing mechanism is aligned with each positioning rod.

[0028] Furthermore, a second positioning hole 13 is opened at the center of each fixing mechanism.

[0029] On the one hand, the function of the heat sink is to dissipate the heat generated by the lighting module during the lighting process. Heat dissipation is achieved by increasing the contact area between the adjustment-free corner lamp module and the air. A smaller first heat sink 15 is provided on the upper surface to leave room for other components. There are no other components on the lower surface, so a larger second heat sink 16 is provided to increase the heat dissipation area.

[0030] In a preferred embodiment, the upper surface of the printed circuit board 2 has a plurality of first mounting holes 22; The first positioning hole 11 is matched with the position of a portion of the first mounting hole 22 to form a first fixing channel for the screw to pass through. The position of a portion of the first mounting hole 22 is matched with the position of the first positioning post 12, so that the positioning post passes through the corresponding first mounting hole 22.

[0031] Specifically, a number of first mounting holes 22 are symmetrically opened on the outer surface of the printed circuit board 2, corresponding one-to-one with the size and position of the first positioning hole 11 and the first positioning post 12.

[0032] In a preferred embodiment, the reflector bowl includes: The fixing plate 3 has several second mounting holes 31 on its upper surface. Some of the second mounting holes 31 are located to match the first fixing channel, and some of the second mounting holes 31 are located to match the first positioning post 12. Reflector 32 is mounted on fixed plate 3.

[0033] Specifically, a number of second mounting holes 31 are formed on the outer surface of the fixing plate 3, corresponding one-to-one in size and position to the first positioning hole 11 and the first positioning post 12.

[0034] On the one hand, each first fixed channel, starting from the positioning plate 1, includes a first positioning hole 11, a first mounting hole 22 and a second mounting hole 31 in sequence, and they correspond one to one. The hole in each first fixed channel is fixed by a screw, and each hole has a corresponding thread on its inner side.

[0035] On the other hand, each first positioning post 12 passes through the corresponding first mounting hole 22 and second mounting hole 31 sequentially from the positioning plate 1 upwards.

[0036] In a preferred embodiment, the reflector 32 is composed of multiple aluminum-plated reflective surfaces.

[0037] Specifically, aluminum surfaces have good reflective properties, which can reduce light loss.

[0038] Furthermore, the surface of the fixing plate 3 is concave, one end of the reflective arc surface is located on the lower side of the concave surface, the arc surface is located above the printed circuit board 2 and surrounds the entire lighting module 21, and the angle between the arc surface and the fixing plate 3 is directed towards the lens module.

[0039] In a preferred embodiment, the central axis of the reflector 32 forms an acute angle with the central axis of the incident surface of the lens 41.

[0040] Specifically, the angle of the acute angle is between 30° and 40° in order to reflect all the light emitted by the lighting module 21 onto the incident surface of the lens 41.

[0041] Furthermore, by adopting a structure in which the reflector 32 and lens 41 are placed at a preset angle, the light distribution pressure of the reflector 32 is reduced. The light does not need to be emitted directly through the reflector bowl, which would cause problems such as glare and uneven light. A shallower reflector bowl can be used to make the interior of the corner light module more compact, thereby achieving overall miniaturization of the corner light module.

[0042] In a preferred embodiment, the lens holder 4 has a plurality of third mounting holes 42. The second positioning hole 13 is matched with the setting position of some of the third mounting holes 42 to form a second fixing channel for screws to pass through. The setting position of some of the third mounting holes 42 is matched with the setting position of the second positioning post 14, so that the second positioning post 14 passes through the corresponding third mounting hole 42.

[0043] In this embodiment, the light-receiving surface of the lens bracket 4 is square, and four third mounting holes 42 are opened at the four corners of the square, which are respectively aligned with the positions of each second positioning hole 13 and each second positioning post 14.

[0044] In this embodiment, a lens 41 is installed on the other side of the lens bracket 4. The angle between the mounting surface and the cut surface of the light receiving surface is an acute angle, so that the reflected light enters the lens 41 at a non-perpendicular angle, achieving the effect of tilted angle supplementary light. This allows the lens to diverge light at a larger angle, while avoiding the central light with the highest light intensity shining directly out and dazzling oncoming vehicles in the direction directly in front of the car.

[0045] Specifically, the mounting surface and the light receiving surface are formed by four supports and four channel surfaces, which together form the channel walls. The light reflected by the reflector bowl enters the lens through the channel walls.

[0046] Furthermore, the light-receiving surface can completely cover the opening end of the reflective arc surface, allowing the reflected light to pass completely through the lens bracket and enter the lighting module.

[0047] Furthermore, the channel wall from the cut surface of the lens holder 4 to the lens 41 is an opaque surface, so that all the reflected light rays reflected by the reflector bowl are incident on the lens 41.

[0048] In a preferred embodiment, the central axis of the incident surface of lens 41 and the central axis of the exit surface of lens 41 form an acute angle.

[0049] Specifically, the angle of the acute angle is usually between 25° and 35°, in order to disperse the light at a large angle, such as Figure 3 As shown, the light trajectory of each calibration-free corner light module radiates outward in a fan shape.

[0050] Furthermore, such as Figure 4 As shown, the emitted light from the adjustment-free corner light module is evenly distributed, with an effective horizontal illumination angle of 90° to 100° and an effective vertical illumination angle of 20°. When both corner lights work simultaneously, the horizontal illumination angle is greater than 180°, and the light can completely cover the blind spot when driving through a curve. Based on this, this solution does not require lens adjustment, achieving an adjustment-free function, simplifying the device structure and reducing costs.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
