Lens capable of achieving multi-position illumination through single light source

Abstract

The invention discloses a lens capable of achieving multi-position illumination through a single light source. The lens comprises a lens body, wherein a light condensation mechanism is arranged at thebottom of the middle of the lens body, a V-shaped groove is formed in the top of the middle of the lens body, fan-shaped holes with arc-shaped surfaces deviating from the V-shaped groove are symmetrically formed in two sides of the V-shaped groove correspondingly, V-shaped holes are further symmetrically formed in the two ends of the V-shaped groove correspondingly, the vertex angles of the V-shaped holes coincide with the end of the V-shaped groove in a matched mode, arc-shaped grooves which are symmetrically distributed in the two sides of the V-shaped groove and matched with a cup are formed in the two sides of the lens body correspondingly, arc-shaped edges of the arc-shaped grooves are inclined arc faces inclining upwards, and the midpoint of the connecting line of the midpoints of the two inclined arc faces is perpendicularly overlapped with the light condensation mechanism. According to the lens, only one light source needs to be arranged at the position of the light condensation mechanism, light rays can be irradiated to the V-shaped groove in a concentrated mode through the light condensation mechanism and are symmetrically reflected to the two sides through the V-shapedgroove, and it is guaranteed that the two arc-shaped grooves have enough light rays for illumination.

Description

technical field [0001] The invention belongs to the technical field of lamps for vehicles, and in particular relates to a lens capable of realizing multiple lighting with a single light source. Background technique [0002] Cars generally have cup holders for placing water glasses, and ambient lights are set in the cup slots of the cup holders for eye-catching purposes. At present, the cup holder atmosphere lights of similar products on the market are divided into two types: the first type, in the form of a lamp head, illuminates the inside of the cup holder from the small hole on the side wall of the cup holder. This solution concentrates the light in a small area and has a small irradiation range , the brightness is uneven; the second type is arranged on the upper edge of the cup holder in the form of a ring-shaped light guide strip. Each ring-shaped light guide strip needs 1-2 LED light sources. Generally, the cup holder of the whole vehicle has two cup slots. This requi...

Problems solved by technology

At present, the cup holder atmosphere lights of similar products on the market are divided into two types: the first type, in the form of a lamp head, illuminates the inside of the cup holder from the small hole on the side wall of the cup holder. , the brightness is uneven; the second type is arranged on the upper edge of the cup holder in the form of a ring-shaped light guide strip. Each ring-shaped light guide strip needs 1-2 LED light sources. Generally, the cup holder of the whole vehicle has two cup slots. This requires 2-4 LED light sources. This type of cup holder ambient light has uniform brightness around the circle, but the structure is complex, there are many components, the processing of the light guide strip is difficult, and the overall cost remains high.
