摘要： Disclosed is a light tube, a light fixture, and a light body. The light tube comprises at least one tube member and at least one flexible filament. The at least one tube member includes a light-transmitting tube including at least one of a diffusion tube, an inner refraction layer, or a diffuse reflection layer to form a tube structure including two or more layers. The at least one tube member is thermally bent to form a regular or irregular shape. The at least one flexible filament penetrates into the at least one tube member. The at least one flexible filament is disposed in the light-transmitting tube after styling, and an inner wall or an outer wall of the light-transmitting tube is provided with the diffusion tube, a coated layer, a coating layer, a frosted layer, or the like, capable of modifying the light effect emitted from the at least one flexible filament, so that the light emitted from the at least one flexible filament can be projected to the light-transmitting tube through the diffusion tube, the coated layer, the coating layer, or the frosted layer and transmitted to the outside through the light-transmitting tube. The diffusion tube, the coated layer, the coating layer, or the frosted layer homogenize the transmitted light, so that the light emitted from the at least one flexible filament can be more uniform.
