Abstract

The invention discloses a light diffusion element, an illuminating device and a motor vehicle. The light diffusion element comprises a light incidence portion, a central light reflection portion, light emergence portions and light guiding portions; the light incidence portion is located at the center of the first side of the light diffusion element and used for receiving incident light; the central light reflection portion is located at the center of the second side, opposite to the first side, of the light diffusion element; the light emergence portions are located at the positions, on the two sides of the central light reflection portion, of the second side of the light diffusion element and used for allowing light to be emerged from the light diffusion element; the light guiding portions are located at the positions, on the two sides of the light incidence portion, of the first side of the light diffusion element; the central light reflection portion is configured to reflect at least part of the incident light from the light incidence portion to the light guiding portions, the light guiding portions are provided with prism arrays, and the prism arrays are configured to reflect at least part of the light reflected by the central light reflection portion to the light emergence portions.

Description

technical field [0001] The invention relates to the field of light illumination, in particular to a light diffusion element, an illumination device and a motor vehicle using the illumination device. Background technique [0002] Lighting devices are indispensable and common devices for industrial production and daily life. However, nowadays, there are relatively strict requirements on the lighting area in many occasions. For example, in some motor vehicle lighting applications or LED lighting applications, it may be necessary to uniformly illuminate only a certain irregularly shaped lighting area, while traditional lighting devices are mainly only suitable for regular shaped areas For lighting. Therefore, this poses a challenge to the flexibility and adaptability of the lighting device. [0003] For this reason, there is a need in the prior art for a lighting device that can adapt to different lighting area shapes. Contents of the invention [0004] One of the objects ...
