Recessed ceiling light fitting has concave reflector and color filters positioned on either side of elongate lamp

摘要

The light fitting has an elongate lamp (1), e.g. a tubular gas discharge lamp, an adjacent concave reflector (3) and color filters (5) positioned on either side of the lamp, for altering the color spectrum of the emitted light received by the concave reflector. The color filters may be rotatable about an axis parallel to the lamp axis, or be displaced perpendicular to the lamp axis.
