Infra-red emitting electroluminescent lamp structures
First Claim
1. A structure for providing electromagnetic wave energy primarily in the near infra-red region of the spectrum, said structure comprisingan electroluminescent lamp element including a red fluorescent dye material for emitting electromagnetic wave energy in the visible and in the near infra-red regions of the spectrum from a surface thereof;
- andat least one layer of optical filter material having selected color filter characteristics positioned over said emitting surface of said electroluminescent lamp element for transmitting electromagnetic wave energy therefrom in a manner such that the amount of energy transmitted in the near infra-red region of the spectrum is substantially increased and the amount of energy transmitted in the visible region of the spectrum is substantially decreased.

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.
