Description

Technical Field

[0001] This invention relates to the field of automotive interior lighting equipment technology, specifically to an in-vehicle ambient dome light. Background Technology

[0002] Currently, all automobiles are equipped with interior dome lights to facilitate entry and exit for drivers and / or passengers at night and to provide visibility of the interior environment. These lights are typically installed on the roof between the driver and passenger seats, providing ample illumination to the passenger compartment when turned on. Existing dome lights generally consist of LEDs or bulbs, a reflector, and a lampshade. The reflector is typically used to concentrate the light, making it more focused and illuminating the target area. However, existing dome light designs have the following drawbacks: 1. Due to the reflector, the structure is relatively thick, with an overall assembly thickness of approximately 3cm, requiring precise installation dimensions; 2. The light from the LEDs shines directly downwards, posing a glare risk to the driver at night; 3. The LEDs are visible through the lampshade, which is quite dazzling and poses an adverse driving risk. In addition, as people's living standards improve, many people have higher and higher requirements for the interior lighting of their cars. Some people will go to car modification shops to install ambient lighting strips in the car after purchasing the car. However, installing ambient lighting strips on your own may change the car's interior structure or electronic circuits, which poses certain risks. Based on the needs of meeting the requirements of interior lighting, protecting the driver's vision, and improving the interior lighting atmosphere, it is necessary to redesign a new structure for the vehicle's overhead lighting. Summary of the Invention

[0003] The purpose of this invention is to provide an in-vehicle ambient dome light that can meet the requirements of in-vehicle lighting while also achieving at least one of the following: the light does not interfere with the driver's vision, improves the in-vehicle lighting atmosphere, and reduces the overall thickness for easy installation and improved aesthetics.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution: An in-vehicle ambient dome light includes a transparent or semi-transparent inner lamp cover, a light guide plate disposed inside the inner lamp cover, an LED light strip disposed opposite one sidewall of the light guide plate, a diffuser plate disposed on the outer side of the light guide plate, an anti-glare film disposed on the outer side of the diffuser plate, the front end face of the anti-glare film being flush with the front end face of the inner lamp cover, a transparent outer lamp cover fitted onto the outer front end of the inner lamp cover, and a linear or rectangular light-shielding film disposed between the inner lamp cover and the outer lamp cover, located in front of the LED light strip and capable of blocking the LED light strip.

[0005] The outer lamp cover is preferably a transparent PC injection molded component. PC material is impact-resistant, high-temperature resistant, and has good toughness, meeting automotive-grade usage and design requirements. The light-shielding film is preferably a screen-printed PC film, whose main function is to shield the LED beads and prevent the light source of the LED beads from being seen through the transparent outer lamp cover. The inner lamp cover is preferably a translucent injection molded PC lamp cover in ice blue, green, yellow, red, purple, orange, cyan, or other colors. After the surface light source shines on the side of the inner lamp cover, a light strip of the corresponding color appears on the outer lamp cover, forming an ambient light effect. The surface light source and anti-glare film are important components of the ambient dome light. The surface light source is the main light source, changing direct light emission to surface-level light emission. The advantage of the surface light source is that the light is soft and not dazzling. The anti-glare film is an optical grade film, whose main function is to constrain the direction of light emission and specifically filter stray light. The light emission direction is basically perpendicular to the light emission surface, so it does not interfere with the driver's vision when the lights are on, increasing driving safety. The diffuser plate can preferably be made of milky white PS material, whose main function is to uniformize the light and improve the uniformity of light. The light guide plate can preferably be made of optically designed acrylic material, which transforms the point light source into a surface light source. The LED light strip is mainly composed of LED beads, resistors, capacitors, etc., and is the main light source of the surface light source.

[0006] To better achieve the above-mentioned objectives, the present invention may further include the following technical solution: a reflective sheet located inside the inner lampshade is provided on the inner side of the light guide plate.

[0007] The reflector sheet reflects and reuses the light from the back, thus improving the light utilization rate of the light guide plate.

[0008] To better achieve the above-mentioned objectives, the present invention may further include the following technical solution: a square-shaped outer protective cover is provided around the rear end of the inner lampshade.

[0009] The outer cover is preferably a milky white opaque PC injection molded part, which mainly serves to shield the lamp beads from the rear, provide protection, and connect the outer lamp cover and the inner lamp cover.

[0010] To better achieve the above-mentioned objectives, the present invention may further include the following technical solution: at least one insertion protrusion is provided around the outer protective cover, and an insertion hole is provided on the side wall of the outer lamp cover to cooperate with the insertion protrusion.

[0011] To better achieve the above-mentioned objectives, the present invention may further include the following technical solution: a plurality of L-shaped connecting buckles connecting the inner lamp cover and the outer cover are provided on the rear end face of the inner lamp cover.

[0012] To better achieve the above-mentioned objectives, the present invention may further include the following technical solutions: a plurality of positioning protrusions are provided around the rear end face of the inner lampshade, and positioning grooves that cooperate with the positioning protrusions are provided on the side walls of the outer cover.

[0013] To better achieve the above-mentioned objectives, the present invention may further include the following technical solution: an ambient skirt is provided around the outer lampshade; Alternatively, a support plate is provided around the outer lamp cover, and an ambient skirt is provided on the front end surface of the support plate.

[0014] Among them, the special luminous patterns formed by the ambient skirt, combined with the color-changing effect of the special color of the inner lamp cover, can create a special visual atmosphere inside the car when the lights are on.

[0015] To better achieve the above-mentioned objectives, the present invention may further include the following technical solution: the inner lampshade is an ice blue, green, yellow, red, purple, orange, cyan, or colored translucent PC lampshade.

[0016] To better achieve the above-mentioned objectives, the present invention may further include the following technical solution: the outer lampshade, the inner lampshade, and / or the outer protective cover are integrally injection molded.

[0017] In summary, the advantages of this invention are as follows: The vehicle ambient dome light of this invention uses a surface light source as the main light source, changing the direct light emission of traditional LED beads or bulbs to full-surface light emission, resulting in soft, non-glaring illumination; the anti-glare film further constrains the light emission direction, filtering stray light, and the light emission direction is basically perpendicular to the light emission surface, so it does not interfere with the driver's vision when the light is on, increasing driving safety; in addition, the light from the LED beads in the LED light strip passes through a light guide plate, through the inner and outer lamp covers, forming a special color halo around the outer lamp cover to create an ambient lighting effect, and the outer lamp cover has an ambient light... When the apron edge is used, the special-colored halo also has a special luminous texture, making the visual effect more prominent; that is, the structure of the vehicle ambient dome light of the present invention has at least the following advantages: 1. The lamp body is ultra-thin, with good adaptability to the installation vehicle models, and the overall thickness can be reduced to about 15mm; 2. The overall surface light source emits soft light without being dazzling; 3. An anti-glare film is added to the light-emitting surface of the surface light source, which protects the driver's vision and improves driving safety when the light is on; 4. The light passes through the special-colored inner lamp cover, and with the special luminous texture design of the ambient skirt edge, it creates a better visual atmosphere inside the car when the light is on.
