Abstract
Piercing, heat sink, and reflector modules are detachably connected together to provide a lighting fixture adaptable to low voltage, line voltage, halogen, fluorescent, incandescent, and other lighting systems. In heat sensitive applications, such as insulated ceilings, a heat conductive basket sleeve is disposed around the heat sink and reflector modules, and the sleeve, heat sink module and reflector module are enclosed within a heat-sealing cover. Heat from the sleeve is conducted to a trim ring externally disposed on the lighting fixture. The lighting fixture permits direct connection to a continuous insulated cable without the requirement of a junction box connection, thereby facilitating installation of the fixture in either new or existing construction.
Claims22
A lighting fixture, comprising:
- a piercing module having a channel defined therein by wails having a length extending across said piercing module and shaped to mate with the outer surface of a predefined continuous insulated electrical cable and at least partially surround said cable in abutting contact therewith, and a means for piercing the insulation of said continuous insulated cable and providing electrical communication between said cable and said piercing means;
- a heat sink module detachably connectable to said piercing module and having a heat sink with a central bore extending through the heat sink and a bulb-receiving socket detachably disposed within said bore of the heat sink, said socket being electrically connectable with said piercing means;
- and
- a reflector module having a trim ring, a reflector support member having a longitudinal axis perpendicular to a mounting surface of the fixture, and a reflector detachably connectable to said heat sink module, said reflector being rotatably mountable in said reflector support member for movement about an axis transverse to said longitudinal axis of the reflector support member, and said reflector support member includes a means for maintaining said reflector at a predetermined position with respect to said transverse axis.
A lighting fixture for mounting in an opening in a predefined surface, comprising:
- an electrical power module having a first means for piercing the insulation of two wires of a continuous insulated cable, a second means for receiving an electric lamp and maintaining said lamp in a fixed position with respect to said power module, and separate first and second electrical circuits extending between said first means and said second means and providing respective separate electrical communication therebetween, wherein at least one of said first and second electrical circuits comprises an elongated strip formed of an electrically conductive metallic material having a portion of said first means integrally formed on a first end of the strip and a portion of said second means integrally formed on a second end of said strip;
- and
- a lamp shield module having a first portion attachable to said electrical power module in fixed relationship therewith, and a means for retaining the lighting fixture in fixed relationship with the opening in said predefined mounting surface when said lighting fixture is mounted in the opening.
