Lighting systems are provided for use in building interiors or for exterior lighting. The lighting systems include a light module formed of a heat conductive structural substrate, together with a lighting configuration formed directly on an exposed surface of the substrate via thick film printing techniques. The substrate is a highly heat conductive material such aluminum or aluminum alloy, and includes an electrically insulating layer printed and cured directly on an exposed surface of the substrate, a circuit layer printed and cured directly on the insulating layer, and a plurality of LEDs electrically attached to the circuit layer. In this manner, 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. The ceiling modules provide electrical and mechanical connectivity to form a self-supporting, integrated ceiling grid. |
