Abstract

A low voltage busbar lighting apparatus which can be easily and cheaply mounted on a building structure and which is suitable for a wide variety of interior lighting applications. The lighting apparatus includes a busbar, a lamp stand or base which is mounted on the busbar and a current supply which is also mounted on the busbar. The busbar includes an adhesive film base and at least one longitudinal steel strip. The lamp base and the current supply are similarly constructed and each includes a base plate and at least one permanent magnet secured to the under side of the base plate.

Claims

1. A low voltage busbar lighting apparatus comprising:

a busbar, said busbar including an adhesive film, a first longitudinal steel strip mounted to said adhesive film and a second longitudinal steel strip mounted to said adhesive film;

a lamp base mounted on said busbar, said lamp base including a base plate, a first permanent magnet secured to said base plate and mounted on said first steel strip, a second permanent magnet secured to said base plate and mounted on said second steel strip and means for electrically connecting said base plate to a lamp;

wherein said busbar may be easily attached to a building structure by said adhesive film;

wherein said lamp base is held to said busbar by the magnetic force developed between said first and second steel strips and said first and second magnets, respectively; and

wherein said busbar further includes an elastomeric ridge interposed between said first and second steel strips, and, wherein said elastomeric ridge rises above said first and second strips.

2. A busbar for a low voltage lighting apparatus comprising:

an adhesive film;

a first longitudinal steel strip mounted to said adhesive film;

a second longitudinal steel strip mounted to said adhesive film;

wherein said busbar may be easily attached to a building structure by said adhesive film;

wherein said low voltage lighting apparatus electrically connects to said first and second longitudinal steel strips by a first magnet and a second magnet; and

further comprising an elastomeric ridge interposed between said first and second steel strips, and, wherein said elastomeric rises above said first and second steel strips.
