RGBW color-mixing light-guide column

Abstract

The invention discloses an RGBW color-mixing light-guide column comprising a column body. A light-transmitting block for emitting light is arranged at the top of the column body; an RGBW four-color LED is arranged at the bottom of the column body; and an inclined surface having an inclination angle is arranged at the side of the column body. The sizes of the column body decreases gradually from the top to bottom. Transparent bead bodies for light refraction are arranged inside the column body, wherein the refractive index of the column body is different from that of the transparent bead body; and the transparent bead bodies having shapes like ellipsoids are distributed inside the column body in a manner of spaced horizontal placing and vertical placing from top to bottom. One end of the light-transmitting block is connected with the column body and the other end is provided with a micro-compound eye for emitting light. Multi-color light emitted by the RGBW four-color LED enters the column body and then are reflected and refracted by the transparent bead bodies by multiple times; and when light is emitted out of the column body, secondary light mixing is carried out by the micro-compound eye at the light-transmitting block. Therefore, light mixing becomes uniform and the market need can be met.

Description

technical field [0001] The invention relates to a light guide column, in particular to an RGBW mixed color light guide column. Background technique [0002] The light guide column is usually used to transmit light, and it is used in various devices. The previous light guide column was used to transmit monochromatic light, and there was no problem of light mixing. Now, due to market demand, some special colors of light are often required. This requires the use of the existing color light to adjust the required color light, but the existing light guide column cannot mix the lights of various colors evenly, or the light mixing effect is very poor, which cannot meet the demand. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide an RGBW color mixing light guide column with good light mixing effect. [0004] The technical solution adopted by the present invention to solve the problem is: RGBW mixed-color li...
