ABSTRACT:
A structure for providing electromagnetic wave energy primarily in the near infra-red region of the spectrum and having an electroluminescent lamp element which includes a red fluorescent dye material for emitting energy in both the visible and the near infra-red regions of the spectrum, and at least one layer of optical filter material having selected color filter characteristics for transmitting electromagnetic wave energy therefrom in a manner such that the amount of energy transmitted in the near infra-red region is substantially increased and the amount of energy transmitted in the visible region is substantially decreased.
