Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to an integrated in-vehicle carpet slow-moving light. Background Technology

[0002] Car projection lights, also known as puddle lights, logo welcome lights, welcome light carpets, or carpet lights (hereinafter collectively referred to as carpet lights), belong to the category of exterior ambient lighting and have attracted widespread attention from young people since their introduction. The patterns they project at night not only serve the functions of locating the car and illuminating the road ahead, but their unique logos or patterns also enhance the sense of technology, ceremony, and nighttime welcome effect. With technological advancements, they have also been endowed with more functions such as signal indication and information exchange. This personalized approach to showcasing their presence has made them increasingly valued by lighting manufacturers, OEMs, and end consumers, resulting in a huge market potential.

[0003] Driving lights, also known as daytime running lights (DRLs), are lights that illuminate during the daytime to make the vehicle more visible to other road users, thereby improving driving safety.

[0004] Traditionally, when carpet lights are installed in vehicle rearview mirrors, the carpet light assembly or other optical projection imaging systems can only be compactly arranged within the rearview mirror housing. If a running light is to be added as an auxiliary light on top of the carpet light in the same rearview mirror, there is no space to accommodate it. Therefore, the running light assembly is usually placed below the bracket connecting the rearview mirror housing and the vehicle body. Due to the limitations of the installation structure and space, the integration and installation of the two light assemblies are quite complex. In terms of optical design, because the traditional arrangement of running lights is placed on the bracket connecting the rearview mirror housing and the vehicle body, their relative spatial position is closer to the vehicle body, which greatly limits the design of the lighting area and light pattern of the running lights. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle-mounted integrated carpet slow-moving light that has a long service life, good durability, and a compact space layout.

[0006] The vehicle-mounted integrated carpet slow-moving light provided by this utility model includes the following technical means: a heat dissipation housing, integrally formed from aluminum metal, having a main body and a cylindrical part extending outward from the main body, with a plurality of heat dissipation fins formed on the outer surface of the main body and the cylindrical part; a base, combined with the heat dissipation housing, forming an internal space between the base and the heat dissipation housing; a carpet light assembly, fixedly disposed in the heat dissipation housing and housed in the internal space and the cylindrical part, with the light outlet of the carpet light assembly exposed above the base; a slow-moving light assembly, fixedly disposed in the heat dissipation housing and housed in the internal space, with the light outlet of the slow-moving light assembly exposed above the base; and a cover plate, combined with the base to shield the carpet light assembly and the slow-moving light assembly, the cover plate being made of a light-transmitting material, wherein the light emitted by the carpet light assembly and the slow-moving light assembly is projected out through the cover plate.

[0007] In a preferred embodiment of this invention, the circuit unit of the carpet lamp assembly can be bonded to the inner surface of the cylinder by means of thermally conductive silicone; thereby, the heat generated by the carpet lamp assembly can be more efficiently conducted to the heat sink housing for heat dissipation.

[0008] In a preferred embodiment of the present invention, a heat sink support can be formed on the inner side of the main body, and the circuit unit of the slow-moving light assembly is bonded to the heat sink support by thermally conductive silicone; thereby, the heat generated by the slow-moving light assembly can be more efficiently conducted to the heat sink housing for heat dissipation.

[0009] Preferably, the cover plate is made of a light-transmitting material, and one side of it is formed as a reflective surface; the housing, the base and the cover plate together constitute the rearview mirror of the vehicle.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model integrates the carpet light assembly, slow-moving light assembly and rearview mirror together through a brand-new structural design. The higher degree of integration allows the carpet light assembly and slow-moving light assembly to be further away from the vehicle body in terms of spatial structure, which makes the optical design of the carpet light assembly and slow-moving light assembly more flexible. In addition, through the improved integrated structure, a brand-new optical system and overall heat dissipation structure can be designed, so that the overall light transmission efficiency and heat dissipation capacity of the machine have excellent performance.

Detailed Implementation

[0014] To facilitate understanding of this utility model, it will be described in detail below with reference to the accompanying drawings and embodiments. The drawings show some, but not all, embodiments of this utility model. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable those skilled in the art to gain a more thorough and comprehensive understanding of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive changes are within the scope of protection of this utility model.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0016] like Figure 1 and Figure 2As shown, the vehicle-mounted integrated carpet slow-moving light provided by this utility model includes: a heat dissipation housing 10, a base 20, a carpet light assembly 30, a slow-moving light assembly 40, and a cover plate 50. The heat dissipation housing 10 serves as a carrier supporting the carpet light assembly 30 and the slow-moving light assembly 40. It is integrally die-cast from aluminum and has a body portion 101. A cylindrical portion 102 extends outward from the body portion 101 for an appropriate length. A plurality of heat dissipation fins 103 are integrally formed on the outer surfaces of both the body portion 101 and the cylindrical portion 102. Preferably, the surface of the heat dissipation housing 10 can be anodized. A radiator support column 104 is integrally formed on the inner surface of the body portion 101. Through the aluminum material with excellent heat dissipation performance and the integrally formed heat dissipation fins 103 and radiator support column 104, the entire carpet slow-moving light has good heat convection and heat radiation capabilities.

[0017] The base 20 is a component used to connect the heat sink housing 10 to assist in positioning the carpet light assembly 30 and the slow-moving light assembly 40. It is not limited to any particular material and has a lamp hole 201. When the base 20 is assembled with the heat sink housing 10, the lamp hole 201 corresponds to the cylindrical portion 102 and the main body portion 101. An internal space S is formed between the base 20 and the heat sink housing 10 to accommodate the carpet light assembly 30 and the slow-moving light assembly 40. Furthermore, a waterproof gasket can be provided between the periphery of the heat sink housing 10 and the base 20, and then the two can be secured together with screws (not shown in the figure) to prevent rainwater, moisture, etc., from seeping into the internal space S.

[0018] The carpet lamp assembly 30 is fixedly mounted on the heat sink housing 10 and housed within the internal space S and the cylindrical portion 102, with the light outlet of the carpet lamp assembly 30 protruding from the lamp hole 201 of the base 20. More specifically, the carpet lamp assembly 30 includes a first circuit unit 301, a first light source unit 302, an image-bearing film 303, and a lens unit 304. The first circuit unit 301, including a circuit board, is bonded to the inner surface of the cylindrical portion 102 of the heat sink housing 10 by thermally conductive silicone material, and then the carpet lamp assembly 30 is secured with screws. The first circuit unit 301 controls whether the first light source unit 302 emits light. The first light source unit 302 includes an LED as a light-emitting element. After emitting light, the light passes through the film 303, and the image on the film is magnified and projected by the lens unit 304. Since the carpet lamp assembly 30 is known technology, a more detailed description of its technical details is omitted.

[0019] The slow-moving light assembly 40 is also fixedly mounted on the heat sink housing 10 and housed within the internal space S, with the light outlet of the slow-moving light assembly 40 exposed above the lamp hole 201 of the base 20. More specifically, the slow-moving light assembly 40 includes a second circuit unit 401, a second light source unit 402, and a light guide lens 403. The second circuit unit 401, which includes a circuit board, can be bonded to the heat sink support 104 of the heat sink housing 10 using thermally conductive silicone material, and then the slow-moving light assembly 40 is secured with screws. The second circuit unit 401 controls whether the second light source unit 402 emits light. The second light source unit 402 includes an LED as a light-emitting element, which emits light and projects it through the light guide lens 403. Since the slow-moving light assembly 40 is known technology, further detailed descriptions of its technical features are omitted.

[0020] The cover plate 50 is an element used to attach to the base 20 to cover the carpet light assembly 30 and the slow-moving light assembly 40 and to act as a reflector. The cover plate 50 is made of a light-transmitting material, and one side of it is formed as a mirror surface 501. After the cover plate 50 is attached to the base 20, the mirror surface 501 faces outward to act as a reflector for the rearview mirror. The light emitted by the carpet light assembly 30 and the slow-moving light assembly 40 is projected out through the cover plate 50. By pre-adjusting the projection angle of the carpet light assembly 30, the carpet light assembly 30 projects an image onto the ground in the form of light and shadow to create a carpet-like effect; the slow-moving light assembly 40 projects light horizontally, making it easier for other road users to identify the vehicle, thereby improving driving safety.

[0021] This utility model, through the aforementioned improved structure, has the following advantages: 1. Since the heat dissipation housing 10 is integrally formed with an extended cylindrical portion 102 to accommodate the carpet lamp assembly 30, the lens unit of the carpet lamp assembly 30 can be designed with a brand-new projection lens barrel with a large aperture and a large field of view (FOV). With a high-power LED as the light source, a larger projection area and higher projection brightness imaging effect can be obtained.

[0022] 2. Due to the improved heat dissipation housing 10 structure, the slow-moving light assembly 40 can use a newly designed irregular light guide lens, combined with a high-power LED as the light source, to create a large area of ​​high-brightness illumination.

[0023] 3. Since the heat dissipation housing 10 is integrally formed with the adjacent main body 101 and cylindrical body 102, it has a compact spatial layout, which enables the arrangement of the carpet light assembly 30 and the slow-moving light assembly in a small space.

[0024] 4. The highly integrated design can reduce the size of the rearview mirror housing, giving vehicle manufacturers more design flexibility when designing models, allowing the entire rearview mirror to be more compact and avoiding the bulkiness of traditional rearview mirrors due to space layout issues.

[0025] 5. This utility model better integrates the carpet light and slow-moving light into the rearview mirror, making the rearview mirror more aesthetically pleasing in terms of optical performance and design.

[0026] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various changes and modifications without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
