Patent

CA 2504427

The present invention provides a light collector. The light collector has a concentration C of dye molecules which absorb and emit light. The dye molecules are dispersed in a light transmissive medium and the concentration C is selected to reduce attenuation that light will suffer due to re-absorption or scattering in the main emission wavelength range of the dye molecules so that the combined emission and absorption efficiency of the light collector is increased.

L'invention concerne un collecteur de lumière. Ce collecteur de lumière présente une concentration <I>C </I>de molécules de colorant qui absorbent et émettent de la lumière. Les molécules de colorant sont dispersées dans un milieu émetteur de lumière et la concentration <I>C </I>est sélectionnée afin de réduire l'atténuation dont souffre la lumière en raison de la réabsorption ou de la diffusion dans la plage de longueur d'onde d'émission principale des molécules de colorant de façon que l'efficacité combinée d'émission et d'absorption dudit collecteur de lumière soit améliorée.
