Strip-shaped light-emitting pole

Abstract

The invention relates to a strip-shaped light-emitting pole which comprises a light guide piece and a point light source, wherein the light guide piece consists of a strip-shaped emergent part, a first light guide part and a second light guide part, wherein the first light guide part is integrally extended from the incident surface of the emergent part, and the second light guide part is integrally extended from the incident surface of the first light guide part. A containing groove is arranged at the tail end of the second light guide part and internally provided with the point light source, the incident surface and the emergent surface of the emergent part are opposite; the incident surface and the emergent surface of the first light guide part are basically perpendicular; and the incident surface and the emergent surface of the second light guide part are opposite. At least one surface of the first light guide part and the second light guide part, expect for the incident surface and the emergent surface is arranged as a reflective surface. According to the strip-shaped light-emitting pole provided by the invention, the two light guide parts are directly arranged on the light-emitting pole according to the light transmission principle; and the reflective surface arranged on each light guide part can be utilized to progressively reflect light emitted by the point light source, so that the emergent light of the light-emitting pole is uniform and the point light source can not be seen.

Description

technical field [0001] The invention relates to a light source and a light guide, in particular to a strip-shaped luminous column. Background technique [0002] Many existing electronic products, such as DVD players or televisions or the edges of lamps, are equipped with strip-shaped luminous columns. These luminous columns generally consist of a rectangular strip-shaped light-transmitting plate and a point light source arranged behind the light-transmitting plate. Usually, the light is uneven, and the point light source can be seen from the outside, which affects the luminous effect and the appearance of the electronic product. In order to ensure that the elongated luminous column emits light as evenly as possible, some products usually use multiple point light sources arranged together to irradiate the luminous column at the same time. rise. Contents of the invention [0003] The purpose of the present invention is to provide a strip-shaped luminous column that can ach...
