Problems solved by technology

[0003] Now solid-state lighting is more mature than LED lighting. LED has attracted much attention due to its high electro-optical conversion efficiency, but the distance between LED chip and phosphor powder is very close, and the luminous efficiency of phosphor powder is severely limited by the heat emitted b

Example Embodiment

[0026] Example 1

[0027] A preparation method of a light-emitting part, which includes a light-leaking optical fiber used to make the light-emitting part, and the preparation method is:

[0028] 1) The light-leaking fiber is chemically corroded by hydrofluoric acid, so that the laser light transmitted in the light-leaking fiber can leak from the corroded place; the method of corrosion treatment is to vertically infiltrate a certain length of fiber into a certain concentration of strong alkali or strong acid. With the pulling method, the fiber is slowly lifted at a certain speed. The roughness of different parts of the fiber will be different if the fiber is in the solution for different soaking time. By controlling the process, the laser can leak out from the side of the corroded fiber with a certain intensity distribution. The corroded part of the optical fiber is defined as the light leakage fiber, and the uncorroded part of the optical fiber is defined as the transmission fiber...

Abstract

The invention discloses a white light source based on a laser, an optical fiber and a light-emitting component, and a light-emitting component manufacturing method, and relates to a white light source and the manufacturing method of a light-emitting component thereof. The manufacturing method of the light-emitting component comprises the following steps of: firstly, etching or engraving the optical fiber, and then solidifying and coating fluorescent powder on the surface of the etched or engraved optical fiber. The white light source based on the laser, the optical fiber and the light-emitting component comprises the laser, the transmission optical fiber and the light-emitting component; the laser is connected with the light-emitting component via the transmission optical fiber. The white light source reduces the loss of light beams during the transmission from the transmission optical fiber to the light-emitting component, facilitates the realization of a linear light source, can separately allocate the laser and the light-emitting component, can install the light source flexibly, ensures that the light-emitting efficiency of the light-emitting component will not be affected by the heat dissipated by the laser, solves the problem that heat dissipation affects light-emitting efficiency, and improves the light-emitting efficiency of the light source, thus the light beams emitted by the light source have uniform color temperature and a high color development index.

Description

technical field [0001] The invention relates to a preparation method of a white light source and a light emitting part thereof, in particular to a preparation method of a white light source based on a laser, an optical fiber and a light emitting part and a light emitting part thereof. Background technique [0002] In recent years, with the increasing demand for energy and the shortage of global resources, energy conservation and emission reduction have received unprecedented attention. As a light source, lasers in the visible band have their own characteristics, especially the development of semiconductor laser technology. The laser as a lighting tool has taken a big step forward. At present, the efficiency of semiconductor lasers with a wavelength of 980 nm is ≥76%. In theory, the efficiency in the visible band will be ≥70%. Such high energy conversion efficiency of semiconductor lasers is more energy-efficient than traditional incandescent and fluorescent lamps. [0003] ...
