Description

Technical Field

[0001] The utility model belongs to the technical field of automotive ambient lights, and specifically relates to an automotive ambient light. Background Art

[0002] Automotive ambient lights are mostly standard features of high-end models, while some low-configured vehicles do not have ambient light functions. The ambient lights on the market are mainly composed of LED lights and light guide elements, generally single-source or dual-source ambient lights. The existing single- or dual-source light guide strip ambient lights generally emit light through gaps or a small part of the structure emits light, and the light-emitting area is relatively narrow and the light emission is uneven, thus affecting the atmosphere effect created by the vehicle's ambient lights.

[0003] The utility model patent with the Chinese patent publication number CN215489226U discloses an overall light-emitting component for an automotive ambient light, including a fixing strip and a light strip. An installation groove for installing the light strip is provided on the fixing strip. One side of the fixing strip is connected to one side of a light-emitting decorative panel, the other side of the light-emitting decorative panel is connected to one side of a reflecting plate, and the other side of the reflecting plate is connected to the fixing strip. One end face of the light strip faces the light-emitting decorative panel. There is a cavity between the light-emitting decorative panel and the reflecting plate, and the included angle between the light-emitting decorative panel and the reflecting plate is an acute angle. The light source uses an LED light strip. After the light of the light source is continuously reflected and refracted by the light-emitting decorative panel and the reflecting plate, it irradiates into the vehicle. The light is more uniform and soft, and the brightness is more in line with the sensory experience, better interpreting the relaxing and comfortable atmosphere of the vehicle. At the same time, due to the action of the convex ring and the light-shielding strip, the light source cannot be directly seen by the naked eye, and problems such as dim light, bright spots, and narrow light-emitting areas existing in single- or dual-source ambient lights are also avoided.

[0004] It still cannot solve the problem that a local lighting effect ambient light is needed at positions such as the middle armrest of the vehicle, but the technical difficulty in the design stage is limited space, and at the same time, ensuring the uniformity of the light source is a technical difficulty.

[0030] The present utility model will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several changes and improvements can still be made. These all belong to the protection scope of the present utility model.

[0031] The present utility model provides an automotive ambient light, including: an upper cover 1, a light guide 2, and a lamp holder 3; the upper cover 1 and the light guide 2 are snap-connected through the snap fasteners inside the upper cover 1; the lower part of the light guide 2 is inserted into the upper part of the lamp holder 3, and the upper cover 1 is made of a transparent material such as acrylic or PC; the top of the upper cover 1 is sprayed with an opaque paint or a light-shielding material by PVD process, so that no light will overflow from the sprayed surface of the entire upper cover 1, and only the unsprayed light-transmitting area will emit light.

[0032] The light guide 2 is designed in a "T" shape; the horizontal part of the "T" shape and the upper cover 1 are both long strip-shaped structures; there are snap fasteners inside the upper cover 1, and the number of snap fasteners is multiple, which are evenly distributed along the length direction inside the upper cover 1.

[0033] The projection of the upper cover 1 along its length direction is a hollow open "U" shape structure;

[0034] A light source is provided in the lamp holder 3, and the light source is disposed opposite to the bottom of the vertical part of the "T" shape of the light guide 2; the light emitted by the light source is output to both sides through the light guide 2 and illuminates the entire inside of the upper cover 1, so that the internal light source is dispersed to the entire upper cover 1 through refraction, and after reflection on the top of the upper cover 1, all the light overflows from the light-transmitting area of the upper cover 1.

[0035] The light guide 2 uses a circular light guide, and a micro-structure is provided on the arc surface of the light guide 2 away from the upper cover 1, and the micro-structure is a smooth tooth design; thus, the light emitted from the light source is all reflected to the top surface of the upper cover 1 through the smooth tooth structure on the light guide 2, and then reflected back between the light guide 2 and the light-transmitting area of the upper cover 1 from the top surface, thereby realizing the improvement of brightness uniformity; the light guide 2 also uses a square light guide.

[0036] To ensure the uniformity around the entire upper cover 1, the tail of the light guide 2 is appropriately bent downward to increase the light brightness value of the entire tail and improve the uniformity around.

[0037] A clamping structure 4 is also provided on the outside of the upper cover 1. The clamping structure 4 is used to connect with the housing outside the atmosphere lamp to fix the position of the atmosphere lamp.

[0038] Such as Figure 3 As shown, a part of the light irradiates on the top surface of the upper cover 1. Since the top surface of the upper cover 1 is light-impermeable, this part is directly reflected and coincides with another part of the light irradiating on the light-transmitting area of the upper cover, increasing the brightness of the entire light. At the same time, because the light teeth of the light guide can be adjusted to improve the brightness uniformity, so as to ensure the output effect of the entire project.

[0039] The structure of the present utility model is simple. By using the technical means of forming an atmosphere lamp only through a long strip-shaped upper cover and a light guide, it occupies a small space, realizes light output at positions such as car armrests, and only through the light tooth design on a partial arc surface of the circular light guide, realizes the convergence of the light irradiating on the light-impermeable area of the upper cover and the light directly irradiating on the light-transmitting area of the upper cover, thereby increasing the brightness of the entire light. The light teeth can be adjusted to improve the brightness uniformity.
