Embodiment

[0023] The invention provides a spectral construction method of an LED light source for a neonatal jaundice treatment instrument, comprising the following steps:

[0024] A1) The absorption spectrum of the standard bilirubin solution is measured experimentally, and the data set of the absorption spectrum is constructed, which is denoted as b=(y 1 ,y 2 ,...,y m ) T Wherein, the concrete operation of measuring the absorption spectrum of standard bilirubin solution is: get about 20mg of standard bilirubin (Bilibubin) reagent (this embodiment adopts the reagent of Dalian Meilun Biotechnology Co., Ltd.) that purity is 99.28%, and precision Weigh; Grind with a small amount of chloroform and transfer to a 100ml brown measuring bottle, sonicate to dissolve; Take it out, let it cool quickly, add chloroform to dilute to the mark, and shake well; Accurately measure 2.5ml, put 100ml brown In the bottle, add chloroform to dilute to the mark, shake well; use a UV-visible spectrophotomete...

Abstract

The invention discloses a spectrum construction method for an LED light source used for neonatal jaundice therapeutic equipment. The method comprises the steps of obtaining the absorption spectrum of a standard bilirubin solution through experiment and constructing the data array of the absorption spectrum; selecting multiple kinds of monochrome LEDs and constructing the spectroscopic data matrix of the multiple kinds of monochrome LEDs; setting the unknown proportionality coefficient matrix of the multiple kinds of monochrome LEDs so that the multiple kinds of monochrome LEDs can generate the absorption spectrum through simulation after being combined according to certain proportion, and constructing an over-determined equation set according to the spectroscopic data matrix and the unknown proportionality coefficient matrix of the multiple kinds of monochrome LEDs and the data array of the absorption spectrum; obtaining the non-negative least-square solution of the over-determined equation set with the simple generic algorithm to further obtain the optimal proportion combination of the multiple kinds of monochrome LEDs and the fitting spectrum of the multiple kinds of monochrome LEDs under the optimal proportioncombination. The method has the advantages of being easy to operate, high in efficiency, high in matching rate and the like.

Description

technical field [0001] The invention relates to a spectrum construction method, in particular to a spectrum construction method of an LED light source used in a neonatal jaundice treatment instrument. Background technique [0002] With the development of optoelectronic technology, the luminous efficiency of light-emitting diodes (LEDs) has been continuously improved. The research of LED light source in the fields of medical treatment, cosmetology, and plant cultivation has attracted widespread attention, and the research and application of LED light source technology in biomedicine have become more and more extensive. Since phototherapy was used to treat neonatal hyperbilirubinemia (jaundice) in 1958, phototherapy equipment with special wavelengths and intensities applied to special parts or special diseases has been widely developed, and its application has greatly reduced the risk of blood exchange. need. [0003] Traditional studies believe that free bilirubin is sensit...
