Anti-sun crack light guide rod

Abstract

The invention provides an anti-sun crack light guide rod comprising a light guide rod body and a light guide lens connection with the top of the light guide rod body; chamfers are arranged at the corners of all side edges and bottom of the light guide rod body. According to the anti-sun crack light guide rod provided by the invention, through arranging the chamfers at the corners of the bottom andside edges of the light guide rod body, when the sunlight reaches the bottom of the light guide rod body, the sunlight can be reflected out, and thus the light guide rod body is prevented from bursting due to excessive gathered optothermal of the sunlight.

Description

technical field [0001] The application belongs to the technical field of manufacturing lighting effects, and in particular relates to a sun-proof cracked light guide rod. Background technique [0002] At present, the common lighting equipment uses fluorescent tubes as light sources to meet environmental protection and energy-saving requirements. Light-emitting devices composed of light-guiding rods and light-emitting diodes arranged on both ends of the light-guiding rods have gradually replaced fluorescent tubes. Its light-emitting design mainly reflects the light reflected by the light-emitting diodes to emit from the light guide rod. However, in the prior art, when the lighting equipment is located outdoors, the light guide rod is also located outdoors. When the outdoor sunlight directly shines on the lens, Since the lens of the light guide rod is a convex lens, it will gather sunlight, and the energy of the gathered sunlight will cause cracking of the light guide rod edge...

[0002] At present, the common lighting equipment uses fluorescent tubes as light sources to meet environmental protection and energy-saving requirements. Light-emitting devices composed of light-guiding rods and light-emitting diodes arranged on both ends of the light-guiding rods have gradually replaced fluorescent tubes. Its light-emitting design mainly reflects the light reflected by the light-emitting diodes to emit from the light guide rod. However, in the prior art, when the lighting equipment is located outdoors, the light guide rod is also located outdoors. When the outdoor sunlight directly shines on the lens, Since the lens of the light guide rod is a convex lens, it will gather sunlight, and the energy of the gathered sunlight will cause cracks on the edge of the light guide rod and the angle of the light guide rod at the rear end of the light guide rod.
