The invention discloses an optical fiber light guiding device, and belongs to the technical field of lighting light sources and packaging. The device comprises a laser light source, optical fiber, a first glass layer, a second glass layer and a fluorescent layer. The laser light source is arranged on the light inlet end side of the optical fiber, and the light outlet end side of the optical fiberis sequentially provided with the first glass layer, the fluorescent layer and the second glass layer. The light outlet end of the optical fiber and the first glass layer are spaced by a certain distance. The fluorescent layer is arranged between the first glass layer and the second glass layer. After light is coupled through the optical fiber, the light is emitted from the tail end of the opticalfiber, the light emitted from the tail end of the optical fiber enters the first glass layer, and the light is motivated at the position of the fluorescent layer and emitted through the second glasslayer. The optical fiber light guiding device is simple in structure, small in reflecting area, good in light effect and low in cost.
Description
technical field [0001] The invention belongs to the technical field of illumination light sources and packaging, and in particular relates to an optical fiber light guiding device. Background technique [0002] Compared with traditional light sources, semiconductor light-emitting diodes (LEDs) have the advantages of energy saving, environmental protection, longer working life, and smaller volume. They are considered to be the most ideal fourth-generation lighting sources to replace traditional fluorescent lamps. At present, the LED lamps used in lighting, display, backlight and other fields are mainly fluorescent down-conversion LEDs. The main light-emitting part is a semiconductor light-emitting chip and a phosphor layer that can be effectively excited by ultraviolet or blue light. The size and uniformity of phosphor particles directly affect the luminous performance of the powder, and the packaging structure of the particles in the LED lamp determines the overall lighting ...
