Embodiment

[0040] The automotive interior lighting ceiling structure of the present application is as follows: figure 2 or image 3 As shown, a light guide plate is embedded in the skeleton of the ceiling, and the surface of the skeleton is kept flat, and the surface of the skeleton is covered with fabric. The front side of the light guide plate is provided with a light outlet, the back side is provided with a light inlet, and the ceiling frame corresponding to the light inlet is provided with a gap. The light enters the light guide plate from the light entrance, and is reflected and transmitted in the light guide plate for many times. When it encounters the light exit, it is irradiated, and the light exit becomes a light-emitting point, realizing the effect of a starry sky ceiling.

[0041] In order to make the matching between the light guide plate and the ceiling frame easier, and to avoid gaps or drops between the edge of the light guide plate and the ceiling frame, which will affe...

Abstract

The light-emitting ceiling of the application comprises a ceiling frame and fabric; the ceiling frame is provided with a light guiding board; the light guiding board is embedded in the ceiling frame and is provided with a light inlet and a light outlet. After entering the light guiding board from the light inlet, the light is reflected multiple times in the light guiding board, and is emitted fromthe light outlet to form a light-emitting point. In this solution, a light source and a light guiding board can be used to form a plurality of light outlets, thereby reducing the number of componentsof the light-emitting ceiling, simplifying the production method of the light-emitting ceiling, and being more suitable for industrial mass production.

Description

technical field [0001] The invention relates to the field of automotive interior ceilings, in particular to an automotive interior lighting ceiling and a production method thereof. Background technique [0002] The car interior ceiling is a very traditional car interior, which plays the role of sound absorption, heat insulation and beauty. After so many years of development, although there are many production processes and different materials, they are basically the structure of skeleton + fabric, and the fabrics are just knitted fabrics, non-woven fabrics, PVC leather, etc., and there has been no major change. [0003] In recent years, consumers have put forward more personalized requirements for car roofs, and roofs with luminous functions such as star roofs have appeared in the car modification market. However, these luminous ceilings are generally hand-made by car modification stores, and have not formed industrial production. For example, punch holes in the ceiling, a...
