ABSTRACT:
A lighting system for a suspended ceiling comprises a central high-frequency power source feeding a plurality of power conditioning units permanently wired-in and mounted in various locations on the permanent ceiling above the suspended ceiling. Each such power conditioning unit provides a power-limited Class-3 high-frequency voltage at an output receptacle and is operable to power a special fluorescent lighting fixture by way of a light-weight flexible two-wire detachable connect cord. Special fluorescent lighting fixtures are mounted in the suspended ceiling, with each such lighting fixture being powered from a power conditioning unit mounted somewhere nearby on the permanent ceiling above. Due to the Class-3 power-limited nature of the output of each of the power conditioning units, as combined with the detachable light-weight and flexible nature of the connect cords, each individual lighting fixture may be treated as a plug-in portable lighting product; which implies a particularly high degree of flexibility in installation and use. As a consequence of the high-frequency operation, the size and weight of the impedance matching means required in the special lighting fixture (to provide proper operation of the fluorescent lamp means therein) is very modest, which results in a particularly compact and light-of-weight lighting fixture.
