Illumination system
A handrail illumination system 15 whereby light emitting diode (LED) current is controlled to illuminate the LEDs 151 in a selected sequence to signify an intended direction of movement and/or speed of movement. The supplied current is ramped up and down with a corresponding increase and decrease in brightness of the LEDs to provide a pulse of light. The LEDs may be addressable individually, or in groups, and be controlled consecutively so that the selected sequence corresponds to a speed of two to four mph and the illumination level may be determined in dependence on whether people are detected in proximity to the handrail by a sensor (175 fig.1).The handrail may be internal or external and part of an escalator, moving walkway or a stairwell.
