Abstract

The invention discloses a light guide device with gradual extension function, comprising a fixing device, an adjusting device, a feedback device and a light incident column, the fixing device is connected to the adjusting device, the feedback device is connected to the fixing device, and the light incident column is fastened to the fixing device , the fixing device includes a light guide seat, the light guide seat and the light incident column are tightly connected, a number of light incident prisms are arranged on the upper end of the light incident column, and the light incident prisms conduct light through the light incident column and the light guide seat, and a light sealing layer is provided on the outside of the light incident column , the light guide seat is a flying wing structure, and there is a diffusion hole on the light guide seat. The light incident column is far away from the light incident prism and the diffusion hole is connected to the light. The lower side of the light guide seat is the light exit surface. , the diffusion part is arranged in an arc shape, and the two sides of the diffusion part are respectively provided with light splitter wings, and the diffusion holes are respectively connected with the light splitter wings and the diffusion part, and the light is converged 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 efficiency to meet the needs of consumers. [0003] At present, various optical products often encounter the situation of insufficient installation space or interference of structural positions during the use process. Therefore, it is necessary to use fewer light sources to meet more special needs. In this case, conventional optical structures may not be able to fulfil requirements. [0004] The light source of the light guide device is generally divided into light entering at both ends or light entering in the middle. The installation of light entering at both ends occupies a large area, while the...

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
