Patent ID: 7081715

Claim:
In combination: A. an illuminating end use of lamps for a stairwell of an office building during work hours that are nominally in use and less frequently in use during off-hours, and B. break-in conditioning of said lamps at said end use thereof; said illuminating end use comprising: (1) a low level illumination in normal off-hour use for power conservation and a high level illumination for effective use of said stairwell characterized in said illumination levels being alternatively operational for each other; (2) a movement-sensing means and a first timer-sensing means characterized in said sensing means being sequentially operational for each other; (3) said movement-sensing means being effective firstly to switch from said low level to said high level illumination operation in response to sensing an individual's movement on said premises; and (4) said timer-operated sensing means being effective secondly to allow said high level illumination to remain in continuous operation but only for a timed duration to correspondingly limit power consumption for said high level illumination to said timed duration; and said break-in conditioning of said lamps comprising: (5) a second timer-sensing means set for a time-sensing duration of at least one hundred hours; (6) an electrically powered fan means operatively effective to emit an air stream; and (7) an operative position of said fan means effective to have said emitted air stream thereof impinge upon said movement-sensing means so as to cause high level illumination of said lamps; whereby said high level illuminating operation of said lamps in situ for said one hundred-hour duration conditions said lamps for subsequent use.
