Lighting fixture with a retractable sensor module and methods of operating the same
First Claim
1. A lighting fixture (100), comprising a lighting means and a support means, is characterized in whichthe lighting fixture (100) is provided with a housing space (101) to receive a sensor module (200);
- the housing space (101) is provided with an internal holder (30) electrically connectable to an electrical circuitry operating the lighting fixture (100);
the sensor module (200) includes a control module (20) comprising a top cover (10), a lower cover (60) and a printed circuit board sub-assembly (50) inside and a lens assembly (50);
adjustment knobs (61) are provided on the control panel wall (62) of the lower cover (60) cooperating with the printed circuit board sub-assembly; and
the sensor module (200) includes electrical circuitry therein to connect with the internal holder (30),whereby the sensor module (200) is retractable or extendable from the internal holder (30) inside the housing space (101) of the lighting fixture (100) to conceal and expose the adjustment knobs (61) appearing on the control panel wall (62) of the lower cover (60).

Abstract
According to a first embodiment of the present invention, a lighting fixture is provided with a housing space to receive a retractable sensor module. The housing space is provided with an internal holder with electrical circuitry to operate the lighting fixture. The internal holder is essentially cylindrical in shape, with one closed end. The closed end is provided with openings and slots for screw and wires. The internal holder allows for pan rotation of a retractable sensor module. The retractable sensor module includes a control module comprising a top cover, a lower cover and a printed circuit board sub-assembly inside, and a lens assembly. The printed circuit board sub-assembly comprises a power printed circuit board, a sensor printed circuit board, with a printed circuit board and a transmitter printed circuit board. The lens assembly constitutes dotted lenses.
The lighting fixture is independently operable, after the sensor module has been detached and a dummy cover is employed to close off the housing space of the internal holder.
In a second embodiment, the lighting fixture with a sensor module can be further fitted with a plug-in transmitter module. The transmitter module receives and re-directs a signal from the sensor module to activate a receiver product, including a chime or a lighting fixture, in a separate part of a building or an operation control room.
