The diffusion part is arranged in an arc shape, light splitting wings are arranged on the two sides of the diffusion part respectively, the diffusion holes are in light conduction with the light splitting wings and the diffusion part respectively, and light convergence is conducted through the light incident prism.

Description

technical field [0001] The invention relates to the technical field of optical elements, in particular to a light guide device with a gradual extension function. Background technique [0002] With the development of science and technology and the continuous popularization of various new products, more and more products use light guide components to improve the appearance or light effect to meet the needs of consumers. [0003] At present, during the use of various optical products, it is often encountered that the installation space is insufficient or the structural position interferes. Therefore, it is necessary to use less light sources to meet more special needs. In this case, the conventional optical structure may not fulfil requirements. [0004] The light source of the light guide device is generally divided into two-end light input or middle light input. The installation of light input at both ends occupies a large area, while the light range of the middle input ligh...

Problems solved by technology

[0003] At present, during the use of various optical products, it is often encountered that the installation space is insufficient or the structural position interferes. Therefore, it is necessary to use less light sources to meet more special needs. In this case, the conventional optical structure may not fulfil requirements

[0004] The light source of the light guide device is generally divided into two-end light input or middle light input. The installation of light input at both ends occupies a large area, while the light range of the middle light input is limited, resulting in a strong light area in the middle and weak light at the edge. even affect the lighting

In addition, the existing light intensity is fixed, and it is impossible to adjust the light intensity according to the non-visible area generated by the occluder within the light range, resulting in weak light in dark areas, and high reflective intensity in some reflective areas, resulting in an obvious junction between light and dark, affecting normal Work
