Description

A light display structure and electronic equipment

technical field

The utility model relates to the technical field of electronic equipment, in particular to a light display structure and electronic equipment.

Background technique

With the improvement of living standards, while users pay more and more attention to the functions of products, they also have higher and higher requirements for the appearance and aesthetics of products. In the process of product design, lighting display effect is a commonly used form to improve the external sense of products, and it can make users interact with the environment well.

There are generally three types of light display effects in existing products. One is the dot lighting effect. There is a light guide column with a circular cross-section inside the product, and the light from the light source is transmitted to the surface of the product through the light guide column to present the dot lighting effect. This presentation method has a simple structure, is easy to implement, and has a low cost.

The other is uniform strip lighting effect or gradient lighting effect. Uniform lighting effects are often provided with multiple light sources to make the strip-shaped lighting effects uniform. This kind of setting consumes a lot of power and has high requirements on the layout of multiple light sources, and problems such as local high brightness and local angle light leakage are prone to occur between adjacent light sources. The gradient lighting effect adjusts the brightness of the light by adjusting the distance between the light source and the presentation surface.

The third is the pattern lighting effect. This method generally sprays oil on the surface or inside of the transparent material to make the rest of the area completely opaque, and then engraves the presented pattern through the laser engraving process. This rendering method is expensive and has uneven lighting.

Existing lighting display effects are point, continuous line or graphic lighting effects presented on only one plane, or discontinuous and disconnected individual lighting effects presented on multiple planes, and the presentation effect is monotonous.
