Description

Light guide structure capable of displaying light with various colors

Technical Field

The application relates to the field of light guide structure, in particular to a light guide structure capable of displaying light with multiple colors.

Background

The light guide structure is commonly used in light guide plates, which are high-tech products for converting point and line light sources into surface light sources. The bottom surface of the plate is printed with light guide points by engraving printing technology. The light emitted from the light source is absorbed by the optical-grade acrylic plate and is continuously and totally reflected inside the plate, when the light irradiates each light guide point, the reflected light can be diffused towards each angle, and then the reflected light is emitted from the front surface of the light guide plate under the condition of destroying the reflection. The light guide plate can uniformly emit light through various light guide points with different densities and sizes.

Considering that the light guide plate technology has many limitations, the light guide plate is replaced by the mode of combining the existing light guide film and the transparent substrate, namely, the light guide plate is replaced by the mode of combining the light guide film and the transparent substrate, the light guide film is generally provided with a plurality of parallel light guide stripes on one surface close to the substrate, light is injected from one side of the substrate, the light enters the substrate and then is injected into the light guide film from the attaching surface of the light guide film and the substrate, the light entering the light guide film is reflected out of the light guide film from one side wall of the light guide stripes, and therefore the light guide plate is replaced by the combination of the light guide film and the substrate. However, in the general light guiding technology, only one color of light can be guided out at the same time at the same or adjacent positions, and the brightness can only be adjusted integrally and cannot be controlled locally, which is relatively monotonous. The pattern which needs to present multicolor or light and shade appears useless.

In view of the above-mentioned related art, the inventor believes that the existing light guide technology of combining the light guide film and the substrate has a problem of exhibiting only a single color.
