Track lighting system with plug-in adapters

A track lighting system comprising:

• at least one track section adapted for mounting onto a surface, the track section having:
• (i) at least one pair of track conductors connected with an AC voltage of frequency substantially higher than that of the voltage normally present on an ordinary electric utility power line, and (ii) a receptacle slot adapted to receive and hold a number of track lighting units;
• and
• at least one track lighting unit operable:
• (i) to be received and held by the receptacle slot, (ii) when so held, to make contact with the track conductors, and (iii) to be powered by the AC voltage present thereon;
• thereby permitting the use of track lighting units adapted to be properly powered only from an AC voltage of frequency substantially higher than that of the voltage normally present on an ordinary electric utility power line.

A track lighting system comprising:

• power track means having track conductors connected with an AC voltage having:
• (i) magnitude about equal to that of the power line voltage on an ordinary electric utility power line, but (ii) frequency substantially higher than that of said power line voltage;
• and
• a track lighting unit operable to connect with the track conductors and, when so connected, to be properly operated by the AC voltage thereon.

A track lighting system comprising:

• a source of voltage of first magnitude;
• a voltage conditioning means connected in circuit with said source of voltage and adapted to provide at a pair of output terminals a voltage of second magnitude, said second magnitude being substantially different from said first magnitude;
• at least one track section having a first and a second pair of track conductors and a receptacle slot adapted to receive and releasably hold a plurality of track lighting units, said first pair of track conductors being connected with said source of voltage, said second pair of track conductors being connected with said output terminals;
• whereby lighting units requiring operating voltages of substantially different magnitude may simultaneously be used in and properly powered from said slot receptacle.

A track lighting system comprising:

• a track section having a first pair and a second pair of track conductors and a receptacle slot adapted to receive and releasably hold a plurality of track plug-in lighting units and track plug-in adapters, said first pair of track conductors being provided with a voltage;
• at least one track plug-in lighting unit adapted to plug into and make contact with said second pair of track conductors;
• and
• a track plug-in adapter adapted to plug into and make contact with both said first pair and said second pair of track conductors and, when so plugged in, operable to effect flow of electric power therebetween;
• whereby the flow of power to said at least one track plug-in lighting unit can be substantially affected by said plug-in adapter.

A track lighting system comprising:

• a source of voltage of a first frequency;
• a voltage conditioning means connected in circuit with said source of voltage and adapted to provide at a pair of output terminals a voltage of a second frequency, said second frequency being substantially different from said first frequency;
• at least one track section having a first and a second pair of track conductors and a receptacle slot adapted to receive and releasably hold a plurality of track lighting units, said first pair of track conductors being connected with said source of voltage, said second pair of track conductors being connected with said output terminals;
• whereby lighting units requiring operating voltages of substantially different frequencies may simultaneously be used in and properly powered from said receptacle slot.

A track lighting system comprising:

• a set of track sections, each section having at least a first pair and a second pair of track conductors and a receptacle slot adapted to receive and removably hold a number of track plug-in units, each track plug-in unit being operable upon insertion into the receptacle slot to make contact with at least one of said pairs of track conductors;
• means by which to connect voltage from an ordinary electric utility power line to said first pair of track conductors;
• and
• a plurality of track plug-in units, at least one of said track plug-in units being a voltage-conditioning adapter operable to make contact with both said first pair and said second pair of track conductors and to effect flow of power therebetween, and at least one of said track plug-in units being a track lighting unit operable to make contact with said second pair of track conductors and to be powered by way of said voltage-conditioning adapter.

A track lighting system comprising:

• a track section having a first pair and a second pair of track conductors and a receptacle slot adapted to receive and releasably hold a plurality of track plug-in units and track plug-in adapters, said first pair of track conductors being provided with the voltage from a regular electric utility power line;
• at least one track plug-in lighting unit adapted to plug into and make contact with said second pair of track conductors;
• and
• at least one track plug-in adapter adapted to plug into and make contact with both said first pair and said second pair of track conductors and, when so plugged in, operable to effect flow of power therebetween.
