Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a small corner fog light module for automotive lighting. Background Technology

[0002] In foggy, snowy, rainy, or dusty environments, driver visibility is extremely low, posing a significant threat to vehicle safety on the road. Fog lights provide a bright, diffused light source with strong penetrating power, serving to alert oncoming drivers and provide some illumination for the driver of the vehicle itself.

[0003] In some existing fog lights, the fog light and corner lights have separate shading parts, and the corner lights and fog lights functions are implemented separately. As a result, it is impossible to further reduce module cost and space size and improve the shape angle while achieving high-performance lighting, which makes dimming difficult and the structure not compact.

[0004] In response, CN219571698U discloses an integrated LED module for corner fog lights, which achieves an integrated design through the cooperation of a lens, a light-blocking bracket, a light-emitting unit, and a heat sink. However, the lens and the light-blocking bracket are simply fixed together. In this case, in order to reduce the overall size of the LED module along the light emission direction, the size of the heat sink needs to be reduced. The size of the heat sink fins directly affects the heat dissipation effect of the entire lighting module.

[0005] Therefore, given the existing technology's inability to balance miniaturization and heat dissipation in integrated LED modules for corner fog lights, further optimization of its structure is necessary. Utility Model Content

[0006] The purpose of this invention is to provide a small corner fog light module for automotive lighting, in order to solve the technical problem of balancing module miniaturization and good heat dissipation.

[0007] The small corner fog light module for vehicle lights of this utility model is implemented as follows:

[0008] A small corner fog light module for automotive lighting includes: a radiator, a light-blocking bracket mating with the radiator, a lens fixed on the light-blocking bracket, and a light source unit fixed on the side of the radiator facing the lens and adapted to emit light; wherein...

[0009] The light emitted by the light source unit is parallel to the driving direction, and the light is suitable for passing through the light-blocking bracket and then being emitted outward from the lens;

[0010] The light-blocking bracket has a semi-enclosed receiving cavity recessed at the side end facing the heat sink, and the side wall of the light-blocking bracket facing the lens also has a light-transmitting opening that communicates with the receiving cavity.

[0011] The heat sink has a protruding positioning part on its end face facing the light-blocking bracket, suitable for embedding into the receiving cavity; the light source unit is fixed on the end face of the positioning part facing the lens; and

[0012] The lens is a freeform surface lens with an arc shape, and the lens is conformally matched with the light-blocking bracket.

[0013] In an optional embodiment of this utility model, the end face of the lens facing the light-blocking bracket has an arc-shaped recessed cavity, and the end face of the light-blocking bracket facing the lens has a protruding positioning wall suitable for embedding into the recessed cavity.

[0014] In an optional embodiment of this utility model, the end face of the lens facing the light-blocking bracket is further provided with a pair of mounting wings symmetrically distributed on both sides of the recessed cavity;

[0015] Each of the mounting fins is folded outward relative to the recessed cavity.

[0016] In an optional embodiment of this utility model, the positioning wall is provided with mounting portions on both sides suitable for one-to-one mating with a pair of mounting wings.

[0017] In an optional embodiment of this utility model, the end face of the heat sink facing the light-blocking bracket and located on both sides of the positioning part is provided with a fixing part suitable for connecting one-to-one with a pair of mounting parts.

[0018] In an optional embodiment of this utility model, each of the mounting wings and the corresponding mounting portion are simultaneously fastened to the corresponding fixing portion by fasteners.

[0019] In an optional embodiment of this invention, the upper and lower edges of the recessed cavity of the lens are provided with aluminum-plated reflective patterns.

[0020] In an optional embodiment of this utility model, the light-blocking bracket is made of black high-temperature resistant PC material; and the thickness of the light-blocking bracket is 1.5 to 2.5 mm.

[0021] In an optional embodiment of this utility model, the heat sink is provided with multiple heat sink fins on the side facing away from the light-blocking bracket.

[0022] In an optional embodiment of this utility model, three dimming ball seats are also distributed on the side of the radiator facing away from the light-blocking bracket.

[0023] By adopting the above technical solution, this utility model has the following beneficial effects: The small corner fog light module for vehicle lights of this utility model improves the compactness of the cooperation between the lens and the light-blocking bracket by conforming the shape of the lens and the bracket. Thus, while taking into account the miniaturization of the entire corner fog light module, it can leave design space for the heat sink of the radiator, thus taking into account both the miniaturization of the module and the good heat dissipation effect.

[0029] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0030] Please see Figures 1 to 4 As shown, this embodiment provides a small corner fog light module for vehicle lights, including: a radiator 1, a light-blocking bracket 3 that mates with the radiator 1, a lens 2 fixed on the light-blocking bracket 3, and a light source unit 4 fixed on the side of the radiator 1 facing the lens 2 and adapted to emit light; wherein the light emitted by the light source unit 4 is parallel to the driving direction, and the light is adapted to pass through the light-blocking bracket 3 and then be emitted outward from the lens 2.

[0031] More specifically, the light-blocking bracket 3 has a semi-enclosed receiving cavity 31 recessed at the side end facing the heat sink 1, and the side wall of the light-blocking bracket 3 facing the lens 2 also has a light-transmitting opening 32 that communicates with the receiving cavity 31; the end face of the heat sink 1 facing the light-blocking bracket 3 has a protruding positioning part 11 suitable for being embedded into the receiving cavity 31; the light source unit 4 is fixed on the end face of the positioning part 11 facing the lens 2; and the lens 2 and the light-blocking bracket 3 are conformally matched.

[0032] Referring to the attached diagram, in one optional scenario, the light source unit 4 uses a single 3-core LED chip with a wavelength range of 500-600nm, which can enhance penetration in foggy weather. Lens 2 is a freeform surface lens with an arc shape, made of PMMA or glass, achieving uniform light distribution over a wide angle of not less than 120° and eliminating edge dark areas. The light-blocking bracket 3 is made of black high-temperature resistant PC material; and its thickness is 1.5–2.5mm. The inner wall of the receiving cavity 31 of the light-blocking bracket 3 is partially aluminum-plated (reflectivity ≥85%) to further reduce stray light effects.

[0033] The radiator 1 can be made of metal, and multiple heat sinks 12 are provided on the side of the radiator 1 facing away from the light-blocking bracket 3. Three dimming ball seats 15 are also distributed on the side of the radiator 1 facing away from the light-blocking bracket 3. Each dimming ball seat 15 is used to support the dimming component 16, so that the radiator 1 can meet the heat dissipation requirements while also serving as a supporting component for the dimming component 16, which greatly reduces the size of the entire small corner fog light module for vehicle lighting.

[0034] The specific arrangement of lens 2, light-blocking bracket 3, and heat sink 1 is as follows:

[0035] First, the end face of the lens 2 facing the light-blocking bracket 3 has an arc-shaped recessed cavity 21, and the end face of the light-blocking bracket 3 facing the lens 2 has a protruding positioning wall 33 suitable for embedding into the recessed cavity 21. This structure allows the lens 2 and the light-blocking bracket 3 to form a conformal fit, improving the compactness of their fit. Thus, while achieving miniaturization of the entire corner fog light module, design space can be provided for the heat sink 12 of the heat sink 1, balancing module miniaturization and good heat dissipation.

[0036] Based on the above, in one optional embodiment, the upper and lower edges of the recessed cavity 21 of the lens 2 are provided with aluminum-plated reflective patterns 22. The width of the aluminum-plated reflective patterns 22 can be selected from 1 to 2.5 mm, which can be used to optimize stray light, reduce light loss, and improve light efficiency.

[0037] Secondly, the end face of the lens 2 facing the light-blocking bracket 3 is also provided with a pair of mounting wings 23 symmetrically distributed on both sides of the recessed cavity 21; each mounting wing 23 is folded outward relative to the recessed cavity 21. The positioning wall 33 has mounting portions 35 on both sides suitable for one-to-one engagement with the pair of mounting wings 23. The end face of the heat sink 1 facing the light-blocking bracket 3 and located on both sides of the positioning portion 11 has fixing portions 13 suitable for one-to-one engagement with the pair of mounting portions 35. Each mounting wing 23 and its corresponding mounting portion 35 are simultaneously fastened to the corresponding fixing portion 13 by fasteners 5, such as, but not limited to, screws. That is to say, the lens 2, the light-blocking bracket 3, and the heat sink 1 can be fastened and assembled simultaneously without needing to be done step by step.

[0038] The small corner fog light module for vehicle lighting disclosed in this utility model uses a metal heat sink 1 and a light-blocking bracket 3 and lens 2 stacked together. While ensuring the lighting performance and uniformity of the corner fog light system, it improves the heat dissipation performance, extends the service life of the module, and achieves the feature of small overall structural space occupation, which meets the current space constraints of modern vehicle lighting design.
