Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive interior lighting technology, specifically to an ambient light for the dashboard area of a car and the car itself. Background Technology
[0002] In automotive interior lighting design, traditional direct lighting solutions typically require a significant vertical distance between the luminaire and the illuminated surface to ensure uniform light coverage. However, in the dashboard (IP) area, especially near the air vents, the height is strictly limited by the vent structure, interior styling, and installation location. Using a traditional direct lighting layout would necessitate significantly raising the luminaire's installation position or altering the interior shape, thus encroaching on interior space and compressing the dashboard layout, affecting its original functionality.
[0003] Patent document CN215335939U discloses an ambient lighting interior trim and a vehicle including the ambient lighting interior trim. The trim includes a light guide element for propagating light, a decorative layer at least partially sewn onto the light guide element, a support frame defining a light guide element receiving space, a substrate defining a light source reserved space together with the support frame, and an LED module configured to be fixedly installed within the light source reserved space to provide a light source. The light source provided by the LED module propagates to the light guide element and then to the outside of the ambient lighting interior trim. This design employs a direct-light layout, where the light guide element requires a significant amount of height space, which cannot meet the installation requirements of ambient lighting near the air conditioning vents in the dashboard area of a car.

[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] This utility model has a simple structure. The lamp components are attached to the IP frame and extended laterally through a T-shaped layout. Only a very small installation height is required in the vertical direction. It can adapt to the space constraints of the lower edge of the air conditioning vent.

[0031] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0032] This utility model discloses an ambient light for the dashboard area of a car and a car. The lighting components are attached to the IP frame and extended laterally through a T-shaped layout. Only a very small installation height is required in the vertical direction. It can adapt to the space constraints of the lower edge of the air conditioning vent. There is no need to raise the lighting fixture or adjust the vent structure. Thus, the shape and function of the car interior can be preserved. It can be directly integrated into the existing IP frame, reducing mold development costs.
[0033] According to the ambient light for the dashboard area of a car provided by this utility model, such as Figure 1 As shown, it includes:
[0034] Printed circuit board 2, which is arranged vertically and has a light source component integrated on its surface;
[0035] Light guide plate 1, which is arranged horizontally and optically coupled to the printed circuit board 2 to form a T-shaped layout;
[0036] The upper shell 4 and the lower shell 3 together form a T-shaped outer shell structure, which covers the outside of the printed circuit board 2 and the light guide plate 1; the lower shell 3 is located on one side of the instrument panel housing 7, and the upper shell 4 is installed at the bottom of the mounting bracket 6 inside the instrument panel housing 7.
[0037] The front end of the light guide plate 1 is provided with an optical texture. The light emitted from the light source component is propagated laterally through the light guide plate 1, and then reflected vertically downwards by the optical texture. After passing through the light-emitting surface of the lower shell 3, it illuminates the lower edge decorative panel 8 of the air conditioner below.
[0038] In a preferred embodiment, the upper shell 4 has a horizontal receiving section for accommodating the light guide plate 1 and a vertical receiving section for accommodating the printed circuit board 2. The horizontal receiving section extends upward near one end of the vertical receiving section to form a fixing part for connection with the mounting bracket 6 via fasteners. The fixing part is provided with a threaded hole, and the fastener includes a bolt 5. The bolt 5 passes through the mounting bracket 6 and is threadedly connected to the threaded hole, and the mounting bracket 6 is fitted against the top surface of the fixing part. The top surface of the fixing part is at the same height as the top surface of the vertical receiving section and transitions smoothly. This arrangement fully utilizes the height difference between the horizontal and vertical receiving sections, allowing the rear and front ends of the mounting bracket 6 to fit against the vertical and horizontal receiving sections respectively, resulting in a more compact space. Similarly, the lower shell 3 has a horizontal receiving section for accommodating the light guide plate 1 and a vertical receiving section for accommodating the printed circuit board 2; the top of the air conditioner lower edge decorative panel 8 is located on the front side of the vertical receiving section, and the vertical receiving section is located on the rear side of the air conditioner lower edge decorative panel 8. Through this structure, the vertically placed printed circuit board 2 and the external shell can be accommodated in the larger area on the rear side of the air conditioner lower edge decorative panel 8, while in the area where the height on the front side is relatively limited, only the light guide plate 1 and the corresponding external shell need to be accommodated.
[0039] In a preferred embodiment, the light source assembly includes an LED lamp group, in which multiple LED beads are arranged at equal intervals in the horizontal direction on the printed circuit board 2. The rear ends of the upper cover 4 and the lower cover 3 need to be opaque to prevent light from emanating from this position, which would cause excess light inside the vehicle. An optical texture design is added to the front light-emitting position of the light guide plate 1 so that all the light at this position is emitted through optical processing to achieve the effect of overall light emission. At the same time, in the vertical direction, a 2mm segment is made at the light guide between each LED bead to ensure that the light from the previous LED bead is not directly transmitted to the light guide of the next LED bead.
[0040] The design width of the light guide plate 1 must match the overall size of the printed circuit board 2 and cannot be less than the width of the printed circuit board 2 to prevent excess light from being unable to enter directly through the light guide plate 1. At the same time, the distance between the light-inlet end of the light guide plate 1 and the LED beads should be controlled within 0.5mm to avoid most of the light from the LED light source being lost, which would lead to a decrease in brightness. The interior of the light guide plate 1 is connected to the upper cover 4 and the lower cover 3 by a snap-fit method to ensure the reliability of the entire structure installation.
[0041] In a preferred embodiment, the light-emitting surface at the front end of the lower shell 3 is covered with an anti-glare film. A sealing strip is provided at the joint between the upper shell 4 and the lower shell 3 to prevent dust and moisture from entering. The lateral extension length of the light guide plate 1 matches the lateral width of the lower edge decorative panel 8 of the air conditioning system in the vehicle dashboard area, and positioning protrusions are provided at both ends to limit installation offset.
[0042] The automobile provided by this utility model includes an ambient light for the dashboard area of the car's windshield. The ambient light is integrated into the dashboard area of the car, and the light-emitting surface of the lower shell 3 is spaced apart from the lower edge decorative panel 8 of the air conditioner. This utility model, through its horizontal T-shaped layout, avoids occupying a large amount of height space, thereby meeting the installation requirements of ambient lights near the air conditioning vents in the dashboard area of the car.
