Abstract: Lighting systems for use in building interiors, for example, which include a plurality of light modules each having an elongate substrate with a lower surface, and electrical circuitry including a plurality of LED units mounted to the lower surface. Each light module is formed as a single-component, packaged construct for easy installation, and facilitates conductive transfer of heat away from the LEDs for enhanced power efficiency. In one embodiment, the light modules are releasably connected to, and extend from, an elongate spine unit which provides structural support and power input to the light modules. In another embodiment, the light modules are disposed parallel to one another and are connected by a series of lateral connectors in laterally spaced relation to one another, with the light modules adjustably mounted to the lateral connectors whereby the spacing between the light modules may be varied.
