Problems solved by technology

[0003] Traditional car sunroofs generally do not have the functions of lighting and colorful ambient light effects. Generally, the indoor lighting of the car body is composed of point light source halogen bulbs or LEDs. Because the point light source projects uneven illumination within the space range, the indoor brightness is uneven and the experience is poor. Generally, the color atmosphere light effect in the car body is composed of linear light sources embedded in the interior panels, which can only achieve local color atmosphere, low brightness, and poor spatial color stereoscopic effect, which cannot achieve the multimedia dynamic color atmosphere optical scene effect
[0004] In general side-entry optical structure design, the LED light source is generally placed on the side of the light guide plate. In order to improve the incident efficiency of the LED light source, the light-emitting surface of the LED light source is usually made to be close to the material of the light guide plate. During the research process of the present invention, it is found that the LED light source When the light-emitting surface is close to the material of the light guide plate, since the single-point LED light source emits linearly and has a certain spatial angle, the light rays incident from multiple single-point LED light sources into the light guide plate will form near the incident surface. The mixed light area with uneven light and shade causes the large-area projected light of the skylight to form local bright and dark band defects in the space

Embodiment 1

[0039] see Figure 1-2 , an automotive sunroof optical structure with both illumination and colored ambient light effects, comprising a sunroof glass 1, the thickness of the sunroof glass 1 is 4-6 mm, the type of the sunroof glass 1 is physical toughened glass or composite laminated glass, the sunroof glass 1 is a double-curvature surface glass, which has good aesthetics, high strength, and is not easy to be damaged. The lower end of the skylight glass 1 is fixedly connected with a fixed light-shielding bracket frame 3, and the lower end of the skylight glass 1 is coated with light-shielding black corresponding to the fixed light-shielding bracket frame 3. Ink 2, the light-shielding black ink 2 has a transmittance of 0%. The light-shielding black ink 2 is coated on the sunroof glass 1 through the printing process to cover the internal structure so that the user cannot see the internal material structure from the top of the sunroof outside the car. It is more beautiful, and the...

Abstract

The invention discloses an automobile skylight optical structure with light effects of both lighting and color atmospheres and belongs to the technical field of automobile skylight optics. The automobile skylight optical structure with the light effects of both lighting and color atmospheres comprises skylight glass, wherein a fixed light shielding bracket frame is fixedly connected with the lowerend of the skylight glass; the lower end of the skylight glass is coated by a light shielding black ink corresponding to the fixed light shielding bracket frame; the fixed light shielding bracket frame is completely shielded by the light shielding black ink; protection glass is fixedly connected with the lower end of the fixed light shielding bracket frame; a light diffusion medium ring is arranged between the skylight glass and the protection glass; light guide glass is fixedly connected with the lower end of the light diffusion medium ring. A uniform surface light emission source is provided by a skylight, and a projection surface light source is adopted to form uniform in-vehicle light, so that the uniformity of in-vehicle space illuminance is improved, an optical scene effect of an in-vehicle space multimedia dynamic colorful atmosphere is improved, and the phenomenon of bright zones and dark zones caused by a conventional lateral entrance optical structure is solved.

Description

technical field [0001] The invention relates to the technical field of automobile sunroof optics, and more specifically relates to an automobile sunroof optical structure having both illumination and color ambient light effects. Background technique [0002] The car sunroof is installed on the roof, which can effectively circulate the air in the car and increase the entry of fresh air. At the same time, the car window can also broaden the field of view and meet the shooting needs of mobile photography. [0003] Traditional car sunroofs generally do not have the functions of lighting and colorful ambient light effects. Generally, the indoor lighting of the car body is composed of point light source halogen bulbs or LEDs. Because the point light source projects uneven illumination within the space range, the indoor brightness is uneven and the experience is poor. Generally, the color atmosphere light effect in the car body is composed of linear light sources embedded in the in...
