obtaining the proportion of the original material according to a proportion recommendation model and the preset requirement of the second product; the proportion recommendation model is used for representing the corresponding relation between the material proportion and the second product parameter;
obtaining an LED product according to the proportion of the raw materials;
the establishment of the ratio recommendation model comprises the following steps:
collecting multiple groups of material proportioning data;
acquiring the second product parameter data corresponding to each group of material proportions;
matching the plurality of groups of material proportioning data with a plurality of groups of second product parameter data to obtain the proportioning recommendation model;
the obtaining of the second product parameter data corresponding to each group of material proportions comprises:
establishing a ratio yield relation curve of different types of packaging mode products; wherein the different packaging mode products are produced by proportioning each group of materials;
and acquiring the second product parameter through the ratio yield relation curve.
2. The method of claim 1, wherein the second product pre-set requirement comprises the raw material and a first product parameter;
wherein the first product parameter comprises one or more of color temperature, wavelength, yield parameter.
3. The method of claim 1, wherein the step of obtaining the LED product according to the raw material ratio further comprises:
collecting product parameter data of the LED product;
comparing the LED product parameter data with the second product parameter data;
and if the LED product yield is higher than the yield corresponding to the second product parameter, taking the LED product parameter as the second product parameter.
