Fluorescent optical fiber and production method thereof, and white light floodlight made from fluorescent optical fiber

Abstract

The invention provides a fluorescent optical fiber, wherein a layer of fluorescent powder is deposited on the surface of an optical fiber. A production method of the fluorescent optical fiber comprises the following steps of: (1) firstly, cleaning the optical fiber, and removing water in a hot air drying way; (2) carrying out mild plasma treatment on the optical fiber, so that the adhesive force of the fluorescent powder to the surface of the optical fiber can be increased; and (3) performing vacuum sputtering by the means that the optical fiber which is performed by the mild plasma surface treatment is put into a low-temperature horizontal magnetron sputtering machine or performing evaporation plating or immersion plating by the means that the purified fluorescent powder is put into a vacuum evaporation plating machine, so that a layer of the fluorescent powder can be obtained on the surface of the optical fiber. A white light floodlight which is made from the fluorescent optical fiber is assembled by the means that the fluorescent optical fiber, an optical lens module, a diode luminescence module and a power source module are matched with one another. The production method of the fluorescent optical fiber is fewer in working procedures and low in cost. The white light floodlight which is made from the fluorescent optical fiber can directly emit white light without secondary light distribution, a lighting angle is approximate to 360 degrees, the light ray is soft, and the white light floodlight is free of glare and faculae.

Description

technical field

[0001] The invention relates to the technical field of white light illumination lamps, in particular to a fluorescent optical fiber, a manufacturing method thereof, and a white light illumination lamp manufactured with the fluorescent optical fiber. Background technique

[0002] In existing LED lighting fixtures, the light source module is usually composed of several LED lamp particles. If the lamp is to emit white light, one or more LED chips need to be packaged, that is, the phosphor powder and transparent packaging glue are fully mixed and placed on the LED chip. On the LED chip, the light of different colors emitted by the LED chip excites the phosphor, and finally mixes into white light. There are many processes, high production costs, and a high defect rate. Due to subtle errors in the packaging process, each lamp chip will emit different light, which increases the difficulty of light distribution. At the same time, because the LED lamp grain is a poin...
