Light guide supporting structure of neon lamp tube

Abstract

The light guide supporting structure of the neon lamp tube comprises an inner sleeve, an outer sleeve and a lampshade, a first positioning cavity is formed in the inner wall of the inner sleeve and used for containing an LED lamp panel, at least two first supporting pieces distributed in the length direction of the inner sleeve are arranged on the outer wall of the inner sleeve, and a second positioning cavity is formed in the outer wall of the inner sleeve and used for containing an LED lamp panel. The inner wall of the outer sleeve is provided with a second positioning cavity, the inner wall of the second positioning cavity is provided with first supporting grooves matched with the first supporting pieces, the inner sleeve is arranged in the outer sleeve, the inner wall of the lampshade is provided with a third positioning cavity, and the third positioning cavity extends inwards to form a plurality of second supporting pieces. The end of the second supporting piece abuts against the wall face of the outer sleeve. And the inner sleeve, the outer sleeve and the lampshade are coaxially arranged. The inner sleeve and the outer sleeve are semi-transparent tubes or milky white, so that double diffuse reflection of light rays of the LED lamp panel is realized, the light rays are uniformly distributed and are softer, and the lampshade has a better stereoscopic impression when displaying light colors.
