Light diffusion structure of light tube and manufacturing method of light diffusion structure

Abstract

The invention discloses a light diffusion structure of a light tube and a manufacturing method of the light diffusion structure. The structure comprises a plurality of joints which are provided with at least one light source, wherein the joints are provided with one glass tube which covers the light source; the glass tube is provided with a rough surface; and an adhesive layer is adhered to the glass tube. The manufacturing method comprises the steps of cutting, burning, annealing, etching, coating, assembling and the like, so that a finished product can be smoothly manufactured. The adhesive layer has light reflecting property and light transmitting property, so that light rays are not shaded to form shadow due to the function of reflecting light; the rough surface is in a misty surface state, so that direct hard light is softened and does not dazzle eyes; and the light rays can be refracted due to the micro concave-convex structure of the rough surface, and the micro concave-convex structure of the rough surface interacts with the adhesive layer, so that light ray diffusion is promoted.

Description

technical field [0001] The invention relates to a structure of a lamp tube and a manufacturing method thereof, in particular to a manufacturing method of a light-diffusing structure of a lamp tube, and a light-diffusing structure produced by the manufacturing method. Background technique [0002] The existing LED lamp tube is coated with a reflective layer inside, and its illumination angle is narrow, and all of them are unidirectional illumination, which is suitable for local accent lighting. Because of the shielding of layers, shadows will appear in the lamp tube on the opposite side of the light, which will affect the overall appearance of the lamp tube, and the illumination will also be insufficient; in addition, in order to prevent the glare of the filament, the existing LED lamp tubes generally have A layer of white film is coated inside the lamp tube to soften the strong light and avoid direct glare from the eyes; however, the above-mentioned means of coating a layer ...
