Method for recommending monochromatic fluorescent powder LED ratio and dispensing amount based on least square method

Abstract

The present invention relates to a method for recommending a monochromatic fluorescent powder LED ratio and a dispensing amount based on the least square method, which comprises the following steps: color coordinates of monochromatic fluorescent powder are selected; the target color coordinates are calculated according to the color coordinates of monochromatic fluorescent powder; the conversion efficiency per unit volume of monochromatic fluorescent powder is calculated according to the target color coordinates; the volume of monochromatic fluorescent powder is calculated according to the target color coordinates and the conversion efficiency per unit volume of monochromatic fluorescent powder; the mass of monochromatic fluorescent powder is calculated according to the volume of monochromatic fluorescent powder; the mass ratio is calculated according to the mass of monochromatic fluorescent powder; and the dispensing amount is calculated according to the mass ratio. The method providedby the invention adopts the algorithm based on big data, when an enterprise user inputs the relevant material information and product information, the mass ratio of fluorescent powder can be recommended by the method, and the algorithm model can be optimized and iterated by continuously using the data; the method is beneficial to improving the accuracy of ratio, helps an engineer to shorten the cycle of sample and trial production, reduce the production cost and improve the production efficiency and yield.

Description

technical field [0001] The invention belongs to the technical field of fluorescent powder LED proportioning, and in particular relates to a single-color phosphor LED proportioning and dispensing amount recommendation method based on the least square method. Background technique [0002] In recent years, my country's LED industry has obvious advantages in industrial development, especially driven by the development of green environmental protection and consumer demand, the field of LED application products has great market potential in the fields of display, lighting, and optical communication. The key materials used in the packaging process of white light LEDs - the main chemical composition of phosphor, the type and concentration of activators and co-solvents, the appearance of crystals, crystal structure, particle size, thermal stability, etc., all directly affect the lumen efficiency, and then affect Luminous properties of LEDs. [0003] At present, the realization of wh...
