The invention discloses a method and device for calculating the proportion of LED fluorescent powder. The method comprises the following steps: calculating actual mixed color coordinates based on bluelight chip color coordinates, two fluorescent powder color coordinates and color coordinates of a target center point in historical data, and performing parameter optimization on an established mixedcolor coordinate calculation model to obtain parameters representing ratios of unit volume conversion rates of two fluorescent powder penetrating through a glue layer in the model; substituting the calculated parameters into the established target color coordinate model, and optimizing the parameters of the target color coordinate model based on historical data to obtain parameters representing the unit volume conversion rate of the fluorescent powder in the model; inputting preset data into the target color coordinate model to calculate the use amount of each fluorescent powder; and finally,calculating the use amounts of the glue and the precipitation powder according to a preset glue-powder ratio. Product quality can be effectively improved, working efficiency is improved, manpower andmaterial resources are saved, and trial and error cost is effectively reduced.
Description
Technical field [0001] The invention belongs to the field of the ratio of phosphors to LEDs, and specifically relates to a method and device for calculating the ratio of two phosphors of LEDs. Background technique [0002] In recent years, my country’s LED industry has had an obvious development trend. Especially driven by the development of green and environmental protection and consumer demand, the LED application product field has huge market potential in fields such as display, lighting, and optical communications. White LEDs have broad application prospects in the lighting market due to the advantages of environmental protection, low energy consumption, and long life. At the same time, with the rapid development of the white light LED industry, people have put forward higher requirements for the performance of white light LED products. Among them, the phosphor glue ratio has a great impact on the performance of the white LED. The slight difference in the ratio of phosphor a...
