A novel method of utilizing an intelligent algorithm to guide the light extraction surface structure designing process for deep-ultraviolet light emitting diodes (DUV-LEDs) is proposed and investigated. Two kinds of surface structures based on the truncated pyramid array (TPA) and truncated cone array (TCA) are applied. which are expected to suppress the total internal reflection (TIR... https://www.inmuebleslasmercedes.com/product-category/soup-tureen-sets/
