Abstract

The invention relates to the technical field of illumination, in particular to a light guide column and an operation key. The light guide column provided by the embodiment of the invention comprises a plate body, the bottom surface of the plate body is a light incident surface, and the top surface of the plate body is a light emergent surface; a plurality of grooves are formed in the bottom surface of the plate body at intervals, and the groove walls of the grooves are cambered surfaces. In the using process, the multiple grooves are formed in the bottom face of the plate body at intervals, the groove walls of the grooves are the cambered surfaces, the light sources are correspondingly installed below the grooves, due to the fact that the bottom face of the plate body serves as the incident face of light, the light can be refracted towards the two sides along the cambered surface groove walls after being refracted by the cambered surface groove walls, the irradiation range of original light is enlarged, and the light sources are not prone to falling off. The gaps between the adjacent grooves are illuminated due to refracted light, so that the black shadow phenomenon between the adjacent light sources is avoided, and the whole light guide column emits light uniformly. The operation key provided by the invention comprises the light guide column, so that the operation key also has the technical effects.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a light guide column and an operation button. Background technique [0002] LED lamps use light-emitting diodes as light-emitting devices, which have the advantages of environmental protection, high efficiency and energy saving, and are gradually replacing traditional lighting lamps. [0003] In related technologies, LED lamps include a light guide column and an LED light source, wherein the light guide column includes a ring sleeve and a light guide plate located below the ring sleeve, and a plurality of LED light sources are arranged below the light guide plate, and the light emitted by the LED light source passes through the light guide column Light up your surroundings. [0004] However, the above-mentioned LED lamps have dark shadows during lighting, which seriously affects the lighting effect. Contents of the invention [0005] The invention provides a light guide col...
