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.

Claims

1. A light therapy device, having replaceable multiple LED array modules used in therapy of visible and invisible skin or tissue disorders that react to various wavelengths of light and providing increased light output per unit area, thus reducing therapy time.

2. The device in claim 1 uses high level of perforation metal core circuit boards in cooperation with heat transfer pads and heat sinks and surface-flow air movement to achieve continuous high output heat dissipation with light outputs of minimum 100 mw/sqcm

3. The device in claim 1 uses multiple LED power levels of mixed wavelengths, fixed wavelengths or pulsed wavelengths.

4. The device in claim 1 utilizing LED array modules that can be replaced on site by non-technician trained user/operators.
