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.

Modular lighting fixture

An electrical distribution system for lighting and the like including a generally C-shaped channel forming a track having guide shoulders on the exterior of the bight portion thereof, and inwardly extending lip portions adjacent the opening thereof for receiving and captively retaining a multiple conductor insulated cable within the channel. A first channel-shaped connector member is provided with inwardly extending guide portions configured for slidably engaging the shoulders of said channel member, the depth of the first connector member being sufficient for receiving therein a second connector member. The second connector member has a body portion with shoulders thereon spaced a distance less than the distance between adjacent edges of the lips of the open end of the channel member. Conductive barbs extend in generally perpendicular relation to the surface of the body portion intermediate the shoulders thereof, the barbs being at positions corresponding to the position of the conductors to be engaged. A pair of tapered leg portions extend from the body portion at positions for abutting the side walls of the channel member. A sliding coaction between the first and second connector members with the second connector member positioned with the shoulders thereof between the lips of the opening urges the barbs into piercing engagement with the insulation therebeneath for establishing electrical contact between the barbs and the conductors.

Electrical distribution system and connector therefor

Fluorescent lamp adapter

In the present apparatus and method, there is first selected a compact fluorescent lamp having a small fluorescent tube and also having a base, there being two contact pins on the base, there also being on such base a starter housing which projects from the base on the side thereof remote from the tube. There is also selected a screw plug having a metal screw portion adapted to screw into a socket for an incandescent lamp bulb, and also having a contact button, the screw portion and contact button being mounted on a hollow insulating body which has a flange at its end remote from the contact button, the flange being recessed and having diametrally opposed boss portions on opposite sides of the body. There is then mounted, on the flange portion, a thin, insulating socket having conductive pin sockets therein adapted to receive the contact pins of the fluorescent lamp. The insulating socket also has an opening adapted to receive the starter housing. The socket is sufficiently thin that the starter housing projects downwardly, far into the body. The insulation socket is so mounted on the flange that, when the fluorescent lamp is assembled with the socket, the pins and pin sockets are disposed laterally of the boss portions instead of being registered therewith. A 'ballast' coil and electrical connectors complete the apparatus, the ballast being caused to be in series-circuit relationship relative to the fluorescent lamp.
