Embodiment 1
[0027] A method for preparing a light-emitting part, which includes a light-leaking optical fiber used to make the light-emitting part, the preparation method being:
[0028] 1) The light-leakage fiber is chemically corroded by hydrofluoric acid, so that the laser transmitted in the light-leakage fiber can leak out from the corroded place; the method of corrosion treatment is to vertically intrude a certain length of fiber into a certain concentration of strong alkali or strong acid to obtain Use the pulling method to slowly lift the optical fiber at a certain speed. The roughness of different parts of the optical fiber will be different depending on the soaking time of the optical fiber in the solution. By controlling the process, the laser can leak from the side of the corroded optical fiber with a certain intensity distribution. The part of the fiber that is corroded is defined as the light-leakage fiber, and the part of the fiber that is not corroded is defined as the trans...
Embodiment 2
[0031] A method for preparing a light-emitting part, which includes a light-leaking optical fiber used to make the light-emitting part, the preparation method being:
[0032] 1) Engraving the light-leakage fiber, so that the laser transmitted in the light-leakage fiber can leak out from the leakage; the part of the fiber that is engraved is defined as the light-leakage fiber, and the part of the fiber that is not engraved is defined as the transmission fiber.
[0033] 2) Red, green, blue, and yellow four-color phosphors are mixed according to the mass percentage of red: 35.1%, green: 38.9%, blue: 18%, yellow: 8%, and then cured on the surface of the light-leaking optical fiber by epoxy resin. The curing process is: add the calculated ratio of fluorescent powder to the calculated ratio of epoxy resin, 1 gram of four-color fluorescent powder mixture: 3 to 6 grams of silica gel or epoxy resin, stir evenly, and use ultrasonic waves for further homogenization treatment , using the ...
