Four fluorescent powder LED proportion and dispensing quantity recommendation method based on least square method

Abstract

The invention relates to a four fluorescent powder LED proportion and dispensing quantity recommendation method based on a least square method. The four fluorescent powder LED proportion and dispensing quantity recommendation method comprises the steps: S1, an LED proportion recommendation model is built based on the least square method according to historical data; S2, an LED dispensing quantityrecommendation model is built through the LED proportion recommendation model; S3, the preset proportion is obtained through preset data and the LED proportion recommendation model; and S4, the presetdispensing quantity is obtained through the preset proportion and the LED dispensing quantity recommendation model. According to the four fluorescent powder LED proportion and dispensing quantity recommendation method based on the least square method, a big data technology is utilized, the LED proportion recommendation model and the LED dispensing quantity recommendation model are built based onthe least square method through the historical data, when a user inputs to-be-produced material information and product information, recommended proportion data can be obtained by the LED proportion recommendation model, the recommended dispensing quantity can be obtained by the LED dispensing quantity recommendation model, sample test and trial-production periods can be shortened, the productioncost is lowered, the production efficiency is improved, and the yield is increased.

Description

technical field [0001] The invention belongs to the field of LED manufacturing industry, and in particular relates to a method for recommending the ratio of four fluorescent powder LEDs and the amount of glue dispensed based on the least square method. Background technique [0002] As the fastest growing light source product in recent years, LED is bound to replace most traditional lighting in the near future and become the mainstream product in the lighting market. Among them, white LED has the advantages of energy saving, environmental protection, small size and long luminous time. It is widely used in many fields such as automobile lighting and indoor lighting, and is the most promising next-generation solid-state light source. While this has brought a broad market space to white light LED packaging factories, it also puts forward higher requirements for the quality level of white light LED packaging. [0003] With the rapid development of the white LED industry, it is b...

Problems solved by technology

At present, the packaging method of white light LED mainly adopts the method of compound emission of white light with blue light chip and yellow phosphor powder, but this method is difficult to produce products with high color rendering index. In order to obtain a higher color rendering index, it is necessary to add yellow, There are four kinds of phosphors: red, green, and patent yellow, but the four phosphors have different effects on the color rendering index and color temperature of LEDs. Therefore, the key to improving the luminous performance of white LEDs lies in setting the ratio of phosphors and the ratio of phosphors and glue reasonably. The matching ratio (referred to as the rubber powder ratio), and the amount of glue per cup of glue will also affect the white light luminous performance

[0004] However, the current theoretical analysis of phosphor powder on the luminous characteristics of white light LEDs is not perfect. The white light engineers of various LED packaging companies rely on historical ratios and manual experience to set the ratio of phosphor powder, and have not formed a systematic phosphor powder deployment process. , resulting in error-prone process and repeated verification, wasting cost and long trial production cycle, time-consuming and labor-intensive, greatly limiting production efficiency and production yield
