A recessed lighting fixture system comprising a power service module which includes sockets for receiving fluorescent light lamps, a ballast for driving each of the light lamps, and a field adjustable connector which is electrically connected to the sockets and the ballasts. The power service module mounts in a mounting frame assembly which is mounted in the ceiling. A primary terminal block is provided in the mounting assembly and is connected to the main power supply. When mounted in the mounting assembly, the field adjustable connector connects to the primary terminal block, thus connecting the light lamps and ballasts to the main power supply. The field adjustable connector is four-pole pre-wired for providing single phase or dual phase power supply to the ballasts of the respective fluorescent light lamps.

The present invention relates to a recessed lighting system and more particularly to a power service module which removably fits into a recessed lighting fixture and drives fluorescent light lamps received therein.
Illumination systems for offices and homes have evolved into complex systems which are designed to be sensitive to many human and other environmental factors. Some illumination systems are controlled by microprocessors for changing the level of brightness of lights throughout a room or building.
It is desirable to have the capability to make adjustments to particular light fixtures after the primary control system is wired. Moreover, the need exists to expand design flexibility in systems, such as daylighting and energy conservation systems.
FIG. 1 is a perspective view of the power service module according to the present invention and a mounting pan into which the power service module is mounted.
FIG. 2 is a side view of the electrical power service module according to the present invention.
FIGS. 3A and 3B are enlarged side views illustrating mounting of the power service module into the mounting pan.
Referring first to FIG. 1, the power service module is generally shown at 14 as part of a recessed lighting system 10. The recessed lighting system 10 comprises a mounting frame assembly 12 which fits into the ceiling and receives the power service module 14. Adjustable mounting brackets 16 are provided on the lateral sides of the mounting frame assembly 12 to allow for adjustable vertical mounting of the mounting frame assembly 12. The power service module 14 receives fluorescent light lamps (FIGS. 4 and 5) and supplies power to drive the fluorescent light lamps. As is well known in the art, additional hardware such as a reflector, radial parabolic louvers and lucite lenses may be attached to the mounting frame assembly 12 beneath the fluorescent light lamps supported by the power service module 14. As will be explained in more detail hereinafter, the power service module 14 fits into a locked position in the mounting frame assembly 12 through a ceiling aperture 18 of the mounting frame assembly 12.
Turning now to FIG. 2, the power service module 14 will be described in greater detail. The power service module 14 comprises a mounting plate 22 supporting thereon three ballasts 24, 26 and 28. A lamp socket holder 30 attaches to the bottom of the mounting plate 22 and supports a lamp socket module 32 for receiving three fluorescent lamps. A snap closure member 34 is provided for connecting the power service module 14 to the mounting frame assembly 12, as will be explained in more detail hereinafter. Side walls 36 are shaped in a semi-parabolic configuration and close the space between the lamp sockets 32 and the mounting plate 22. A plastic cap 38 is provided to fit into each of the sockets of the lamp socket module 32 that are not being used. Secured to the undercarriage portion of the power service module 14 is a field adjustable connector 40 (also referred to as a secondary terminal block). The field adjustable connector 40 is a four-pole plug assembly which is pre-wired and is adjustable for single, dual or three phase circuit arrangements and for integration with a microprocessor-based energy management control system. The ballasts 24, 26 and 28 may be Class "P" NPF Reactor ballasts, rated at 118 V, 60 Hz.
FIGS. 3A and 3B illustrate the attachment of the power service module 14 to the mounting frame assembly 12. The mounting frame assembly 12 comprises a wiring compartment 42 supporting a primary supply terminal block 44. The field adjustable connector 40 of the power service module 14 comprises phase contact plugs 46 designed to mate with and be received by individual terminals (see FIG. 5B) in the primary supply terminal block 44 in the mounting frame assembly 12. The field adjustable connector 40 and the primary supply terminal block 44 are manufactured by WAGO Kontakttechnik GmbH, model Nos. 277-123, 277-124, 277-125 (secondary terminal block 40) and 277-121 and 277-131 (primary terminal block 44). Guide members 48 and 50 are provided on the power service module 14 proximate the field adjustable connector 40. In addition, an alignment member 52 is provided in the wiring compartment 42 to cooperate with the guide member 50. The field adjustable connector 40 is inserted into the wiring compartment 42 to mate with the primary supply terminal block 44. The snap closure member 34 fits around the wall of the wiring compartment 42 to secure the power service module 14 in the mounting frame assembly 12.
