Study on Irradiation Uniformity of Array Blue LED in Jaundice Treatment Box

The uniformity of blue LED array in jaundice treatment box is improved. The mathematical model of illumination uniformity algorithm for inner and outer LED arrays layout is established. Taking the actual size of blue light board in jaundice treatment box as an example, the optimal illumination uniformity with best LED arrays layout are obtained through programming iteration and simulation verification. The uniformity of blue light LED improved 42.9 % comparing with tradition LED arrays.
