Abstract: This device incorporates an array of light emitting diodes (LED) of several specific wavelengths that are used to provide therapy to visible and invisible living tissue or skin disorders that react to various wavelengths of light. Furthermore the device uses a combination of high level of perforation metal core circuit boards, heat transfer pads, heat sinks and forced air cooling and electronic thermal management to achieve continuous high intensity light output to therapy areas along with long LED life. The invention is using replaceable LED modules enabling device maintenance by user operators not trained as maintenance technicians.
