1. A system for initiating a de-icing action on ice which has formed on a substrate material, the system comprising:
(a) a substrate material which is transmissive for at least one selected wavelength corresponding to an absorption peak of ice and on which ice has formed;
(b) irradiation producing devices operative to emit a first type of narrowband irradiation matching the at least one selected wavelength corresponding to an absorption peak of the ice, being transmissive through the substrate material and being within a range centered on approximately 1456 nm or 1950 nm, that passes through at least some portion of the substrate so that a first portion of ice that is impacted by the irradiation is an interfacial portion nearest a surface of the substrate, the devices being proximate the substrate material, and selectively activated to effect irradiation, causing melting of at least some ice nearest the surface of the substrate, wherein the irradiation producing devices are narrowband semiconductor irradiation devices mounted as an array on a mounting board; and,
(c) a controller configured to control the irradiation producing devices, wherein the controller comprises a feedback system configured to measure the temperature of the ice and to change the output of the array based on measured temperature changes of the ice.
