A lighting system for illuminating a chamber in a building includes a lighting fixture suitable for being mounted onto a surface of the chamber, so that light emitted by at least one CCFL device mechanically supported by the fixture illuminates the chamber. The one CCFL device includes at least one transformer. A driver adapted to be connected to a surface of the chamber is capable of converting input power from a power source to an AC power having a voltage in the range of about 5-400 volts at a frequency in the range of about 1kc-100 kc. The at least one transformer is suitable for converting the AC power to an output power suitable for operating the at least one CCFL, causing the at least one CCFL to emit light. Physically separating the driver from the at least one CCFL device reduces the adverse effects of heat generated by the at least one CCFL device on the driver and increasing the useful life of the CCFL lighting system. A controller may be used to control light emitted substantially simultaneously by a plurality of the above lighting systems, such as for large commercial or public area illumination, by sending signals to the drivers to control the amount of power that is supplied to the CCFLs. Different power may be separately supplied to CCFLs having different phosphors in each of a plurality of CCFL devices in a plurality of the lighting systems, to adjust substantially simultaneously the color temperature of light emitted by the lighting systems. |
