AI Technical Summary

Technical Problem

When existing fill light lamps achieve the light output effect of the LOGO shape, they are costly and have poor heat dissipation performance, resulting in poor service performance.

Method used

The strip-shaped structure of the light guide column is adopted to reflect light through the first reflective surface and the second reflective surface to form a larger light-emitting area, reduce the number of light-emitting light sources, reduce costs and improve heat dissipation performance.

Benefits of technology

While maintaining the LOGO shape light output effect, it realizes that the manufacturing cost of fill light lamps is reduced and the heat dissipation performance is improved, and the use performance and luminous uniformity are improved.

Abstract

The invention discloses a light supplementing lamp and electronic equipment, and belongs to the technical field of optical devices. The light supplementing lamp comprises a first light emitting source and a light guide column; the light guide column is a strip-shaped structural member and is provided with a first end and a second end; the light guide column comprises a first light incoming surface, a strip-shaped light outgoing surface, a first reflecting surface and a second reflecting surface, the first reflecting surface is located on the end surface of the first end of the light guide column, and the first light incoming surface and the second reflecting surface are both located on the side, away from the strip-shaped light outgoing surface, of the light guide column; the first incident surface is located on the side, close to the first reflecting surface, of the second reflecting surface, the edges of the two opposite sides of the first reflecting surface intersect with the strip-shaped emergent surface and the first incident surface respectively, and the distance between the strip-shaped emergent surface and the second reflecting surface is gradually reduced in the direction from the first end to the second end; light emitted by the first light-emitting light source is reflected by the first reflecting surface and the second reflecting surface and then is emitted from the strip-shaped light-emitting surface.
