Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an automotive lighting module and a car using the same. Background Technology

[0002] As the design of vehicle lights gradually moves towards compactness, miniaturization, and lightweighting, the functional requirements for vehicle lights tend to develop towards having reusable functions.

[0003] For example, CN222864747U discloses a vehicle lamp and a car using the same, which employs an inner and outer lamp cover. The colors of the inner and outer lamp covers are a specific combination of green and pink; that is, when the inner lamp cover is pink, the outer lamp cover is green, and vice versa. A white beam of light emitted from the light source towards the inner lamp cover is then filtered through the combined action of the inner and outer lamp covers to emit white light, thus solving the problem of emitting white light even with a non-white lamp cover, meeting the requirements of a vehicle lamp. This structure of the vehicle lamp meets the requirements for white reversing lights, but it cannot meet the requirements for turn signals.

[0004] However, since the reversing lights and turn signals are different colors, the viewing surface cannot be fully reused; otherwise, they cannot be illuminated simultaneously. To address this, publication number CN217131140U discloses a vehicle light that partially reuses turn signals and reversing lights. This method integrates the turn signals and reversing lights into one unit by dividing the overall vehicle light into a turn signal viewing surface and a reversing light viewing surface. While this disclosed technology achieves a dual-purpose light, the miniaturization of the overall vehicle light is still not ideal due to the need for partitioning the light surface.

[0005] Therefore, given the shortcomings of existing automotive lights in achieving both miniaturization and dual-beam output, further optimization of the headlight structure is needed. Utility Model Content

[0006] The primary objective of this invention is to provide a vehicle headlight module that addresses the technical challenge of balancing miniaturization and dual-beam output.

[0007] The second objective of this invention is to provide an automobile that solves the technical problem of enabling its headlight module to achieve both miniaturization and dual-beam output.

[0008] The vehicle headlight module of this utility model is implemented as follows:

[0009] A vehicle lighting module includes: a cooperating light source assembly, a reflector, and an outer lamp cover; wherein

[0010] The light source assembly includes a first light source suitable for emitting yellow light and a second light source suitable for emitting green light, arranged side by side;

[0011] The outer lamp cover is either pink or red.

[0012] In an optional embodiment of this invention, the second light source is located at the focal point of the reflector.

[0013] In an optional embodiment of this invention, the first light source is located at the defocus position of the reflector.

[0014] In an optional embodiment of this invention, both the first light source and the second light source are positioned above the reflector.

[0015] In an optional embodiment of this utility model, the vehicle lamp module further includes an inner lamp cover disposed between the reflector and the outer lamp cover.

[0016] In an optional embodiment of this utility model, the inner lampshade body and the reflector are integrally formed.

[0017] In an optional embodiment of this invention, the inner lampshade has a light-incident surface facing the reflector and a light-exiting surface facing the outer lampshade; and

[0018] Optical patterns are provided on both the light-incident surface and the light-exit surface of the inner lamp cover.

[0019] In an optional embodiment of this invention, the optical pattern on the light-incident surface of the inner lampshade is an array of multiple triangular patterns; and

[0020] The optical pattern on the light-emitting surface of the inner lamp cover consists of multiple circular patterns arranged in an array.

[0021] In an optional embodiment of this invention, both the first light source and the second light source are disposed on a printed circuit board and are turned on separately by an electrical signal from the printed circuit board, so that the brightness of the first light source and the second light source can be controlled individually.

[0022] The automobile of this utility model is implemented as follows:

[0023] An automobile includes: the aforementioned optical system.

[0024] By adopting the above technical solution, the present invention has the following beneficial effects: The vehicle lamp module of the present invention and the car using it can simultaneously meet the functions of reversing lights and turn signals of the vehicle lamp by emitting first and second light sources of different colors, as long as an outer lamp cover is configured.

[0030] 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.

[0031] Example 1:

[0032] Please see Figures 1 to 4 As shown, this embodiment provides a vehicle headlight module, including: a cooperating light source assembly, a reflector 3, and an outer lamp cover 2; wherein the light source assembly includes a first light source 11 suitable for emitting yellow light and a second light source 12 suitable for emitting green light, arranged side by side; the outer lamp cover 2 is a pink or red cover. The material of the outer lamp cover 2 can be PMMA or PC.

[0033] In this embodiment, the outer lamp cover 2 and the housing 7 cooperate to form a sealed cavity for the entire vehicle lamp module. The outer lamp cover 2 is provided with welding ribs 21 for sealing and fixing between the outer lamp cover 2 and the housing 7. The welding ribs 21 can be designed with different welding forms according to different styling requirements. The light source assembly and the reflector 3 are both built into the sealed cavity. It is understood that a decorative ring 6 is also provided within the sealed cavity, located between the outer lamp cover 2 and the reflector 3. The reflector 3 is suitable for snap-fit ​​and screw-fit engagement with the housing 7.

[0034] Based on the above structure, the second light source 12 is located at the focal point of the reflector 3 to form a focused light source pattern, while the first light source 11 is located at the defocused position (i.e., non-focal position) of the reflector 3 to form a non-focal light source pattern. Both the first light source 11 and the second light source 12 are positioned above the reflector 3. The reflector 3 is aluminum-plated or chrome-plated.

[0035] Furthermore, regarding the reflector 3 in this embodiment, it should be noted that a section of observable pattern 31 is designed on the reflective surface of the reflector 3 near the light source assembly.

[0036] The first light source 11 and the second light source 12 are both disposed on the printed circuit board 4 and are turned on separately by electrical signals from the printed circuit board 4, so that the brightness of the first light source 11 and the second light source 12 can be controlled individually. That is, the second light source 12 is mounted on the printed circuit board 4 separately from the first light source 11 and is turned on and emits light by electrical signals from the printed circuit board 4. The printed circuit board 4 is suitable for snap-fit ​​and screw engagement with the housing 7.

[0037] Furthermore, it should be noted that the vehicle headlight module in this embodiment also includes an inner lamp cover 5 disposed between the reflector 3 and the outer lamp cover 2. Optionally, the inner lamp cover 5 and the reflector 3 are integrally formed.

[0038] Based on the above, the inner lampshade 5 has a light-incident surface facing the reflector 3 and a light-exiting surface facing the outer lampshade 2; and optical patterns are provided on both the light-incident and light-exiting surfaces of the inner lampshade 5.

[0039] Referring to the accompanying drawings, in one optional embodiment, the optical pattern on the light-incident surface of the inner lampshade 5 is a plurality of triangular patterns 51 arranged in an array; and the optical pattern on the light-emitting surface of the inner lampshade 5 is a plurality of circular patterns 52 arranged in an array. As a specific optional embodiment, each circular pattern 52 has a diameter of 1 mm, and each triangular pattern 51 has a size of 1.5 mm.

[0040] In summary, for the headlight module of this embodiment, when the second light source 12 is turned on or flashes, the pink or red of the outer lamp cover 2 and the green of the second light source have a complementary color relationship, so that the green light emitted by the second light source 12 is transmitted to the following vehicle as a white reversing signal through the pink or red outer lamp cover 2; when the first light source 11 is turned on or flashes, the first light source 11 emits yellow light through the pink or red outer lamp cover 2 to notify the following vehicle of a yellow turn signal, etc. Therefore, the headlight module of this embodiment, by emitting different colored light from the first light source 11 and the second light source 12, can simultaneously satisfy the functions of reversing light and turn signal with only one outer lamp cover 2. Moreover, this design does not require partitioning of the visual surface of the outer lamp cover 2. Therefore, on the one hand, it can meet the requirements of miniaturization and lightweighting of the headlight module, and on the other hand, it can reduce production costs. Furthermore, the outer lamp cover 2 in this embodiment is not only used to match the housing 7 to form a sealed cavity, but also to coordinate the different colors of light emitted by the first light source 11 and the second light source 12 to adjust the final light output effect. Therefore, the outer lamp cover 2 serves a dual purpose and simplifies the structure of the overall vehicle lamp module.

[0041] Example 2:

[0042] Based on the headlight module of Embodiment 1, this embodiment provides a car, including: the headlight module of Embodiment 1.

[0043] Specifically, in this embodiment, the first light source 11 in the headlight module emits yellow light. When turned on or flashing, the first light source 11 emitting yellow light indicates the direction of the vehicle. That is, when the first light source 11 on the left side of the vehicle is turned on, the first light source 11 notifies vehicles behind of the vehicle's left turn signal. When the first light source 11 on the right side of the vehicle is turned on, the first light source 11 notifies vehicles behind of the vehicle's right turn signal.
