Abstract

The invention provides a vehicle inner lampshade, a vehicle lamp and a vehicle. The vehicle inner lampshade comprises a body, which is of a blocky structure; a condenser total reflection surface is formed at one end, facing the light source, of the body; one end, back to the light source, of the body forms a light emitting surface, the condenser total reflection surface is provided with a dimminghole extending in the direction back to the light source, and the condenser total reflection surface and / or at least one part of the inner wall surface of the dimming hole are / is provided with diffusion patterns capable of diffusing light. According to the vehicle inner lampshade, due to the fact that the diffusion patterns are arranged on the condenser total reflection surface and / or the dimminghole of the body, the vehicle inner lampshade can enable light emitting of the light emitting face to be more uniform, and the problem that a direct-injection type thick-wall part is uneven in lighting is solved.

Description

technical field [0001] The invention relates to the field of vehicles, more specifically, to an interior lampshade for a vehicle, a vehicle lamp and a vehicle. Background technique [0002] With the increasing development of automotive lighting technology, the application of LED lamps in automotive lights is becoming more and more common. In order to meet the needs of users for novel appearance and modeling, the realization methods of lamps and lanterns are also becoming more and more diverse. Among them, the combination of LEDs and thick-walled parts can achieve a multi-window effect, but the lighting of the existing concentrator form is obviously grainy, and it is impossible to achieve an overall uniform lighting effect on the light-emitting surface. The shallower the depth of the inner lampshade, the more obvious the graininess, and the design of the lamp is often limited by the modeling space, which cannot reach a certain depth, and the concentrator has high requirement...
