Abstract
A remote illumination system having a remote illumination module containing a single point source of light for distribution to one of more destinations through a light pipe. The overall system is adjustably sensitive to external ambient light conditions wherein the single light source is automatically energized during conditions of diminishing light for distribution to one or more destinations through the light pipe.
Claims31
A remote illumination apparatus comprising:
- light generating means, received within a housing, for generating visible light;
- access means for selectively providing access to the light generating means through the housing when in a first position and sealing the housing when in a second position;
- light concentrating means, within the housing, for concentrating the visible light;
- a first elongate fiber optic bundle for receiving the concentrated visible light at a visible light input end within the housing and directing the received light to a visible light output end;
- diffuser means at the visible light output end of the first fiber optic bundle for diffusing the directed visible light;
- a second elongate fiber optic bundle for receiving ambient light at an ambient light input end and directing the received ambient light to a control circuit within the housing;
- control circuit means within the housing for receiving the directed ambient light;
- detecting means, within the control circuit means, for detecting an intensity of the ambient light received at the control circuit and generating a signal representative of the detected intensity;
- power delivery means within the control circuit means for selectively delivering power from a power connection within the housing to the light generating means responsive to the signal being with a predetermined range;
- and,
- switch means within the control circuit means for selectively connecting the power connection with a source of power external the housing when the access means is in the second position.
