Patent ID: 7909499

Claim:
A track light module for use with a low-voltage track carrying a pair of elongated conductors transversely spaced from each other and accessible through a longitudinal slot in the track, said module comprising a first housing containing a printed circuit board carrying an LED, said first housing forming an aperture permitting light from said LED to be radiated beyond said first housing, a second housing carrying a pair of electrical conductors adapted to extend into the low-voltage track to make contact with said conductors within said track, said second housing also including surfaces for fastening said second housing to said track when said second housing and said track are rotated relative to each other, and said electrical conductors in said second housing are adapted to engage said conductors within said track when said second housing is rotated relative to said track; wherein said surfaces for fastening said second housing to said track comprise two pairs of spaced flanges, one flange in each pair being narrow enough to fit into said longitudinal slot in said track, said flanges having opposed surfaces that slide across the top and bottom surfaces of the top wall of said track when said second housing is rotated within said slot, with the ends of said flanges sliding across the bottom surface of said to wall engaging the inside surfaces of the side walls of said track.
