Embodiment Construction
[0016] The method of the present invention is described in detail below with reference to the accompanying drawings.
[0017] The present invention will be further described below in conjunction with accompanying drawing.
[0018] The light distribution technology component involved in the present invention is composed of a single blue LED light source, an exciting fluorescent optical fiber, and a fluorescent powder. The light distribution is realized through the excitation fluorescent optical fiber light guide light distribution and the phosphor powder is excited on the side light-emitting surface to achieve excellent light distribution. Lighting effect, so that the light is more uniform, the color temperature is more stable, and at the same time, it can give full play to the characteristics of flexible use of LED.
[0019] It is characterized in that it uses excited fluorescent optical fiber to guide and distribute light and excites remote phosphors to emit light. It uses a ...

The invention provides an optical fiber type remote light distribution method realized by the aid of fluorescent powder. A single LED blue light source, an excitation fluorescent optical fiber and the fluorescent powder are required in the method. The excitation fluorescent optical fiber realizes light guiding and light distribution and excites the fluorescent powder on a lateral luminous surface so as to realize light distribution, and an excellent light distribution illuminating effect is achieved. Manufacturing steps include spraying the excitation fluorescent powder on the surface of a side optical fiber; spraying a polyester protective film on the outer portion of the excitation fluorescent powder to manufacture the excitation fluorescent optical fiber; abutting an end of the excitation fluorescent optical fiber with the single LED blue light source; leading the excitation fluorescent optical fiber to be luminous integrally by the aid of optical conduction of the excitation fluorescent optical fiber; and bending the excitation fluorescent optical fiber into an optional shape to realize the purpose of decoration and light distribution for an article by the aid of the characteristic of flexibility of the excitation fluorescent optical fiber. In addition, optical fibers coated or laminated with different fluorescent powders can be replaced according to illumination requirements.
Description
technical field [0001] The invention relates to the field of high-power LED white light illumination, in particular to optical fiber remote fluorescent powder light distribution. Background technique [0002] Based on the characteristics of long life, high efficiency, and high light utilization rate of LEDs, high-power LED lighting has been widely used in daily lighting, and many technical problems have also been encountered during use. Many attempts have been made to solve the application problem, but it is not difficult to see that the light distribution technology has not been well developed in the past two or three years. The reasons are: high cost, complex light distribution, and low light source utilization. The common light distribution technology at this stage generally uses frosted lampshades to diffuse light or uses optical lenses, reflective bowls (cups) and other methods for light distribution. Due to the problems of optics, machinery, materials, and processing t...
