Abstract

A solid-state lighting system (10) has a carrier (12 or 12a) having at least two electrically conductive traces (14, 16) thereon; and at least one module (18) carrying at least one solid-state light source (20) mounted with the carrier. The module (18) has electrical conductors (22, 24) in contact with the electrically conductive traces (14, 16) on the carrier. The carrier (12 or 12a) is elongated and the at least one module (18) has a horizontal aperture (26) therethrough with the electrical conductors (22, 24) extending at least into the aperture. The module (18) is slidably mounted upon the carrier (12 or 12a) with the carrier penetrating the horizontal aperture (26) and the electrical conductors (22, 24) in engagement with the electrical traces (14, 16).
