Abstract
Device for providing comprising: A panel having rigid layer having a patterned electrical circuit thereon. An array of illuminating units, each unit being formed by at least one rigid element and a portion of the rigid layer; and including: a rigid optical dispersing element, a light source sandwiched within the panel for generating light from electrical energy, and an electrical conductor. The electrical conductor being the primary heat sink for the light source, the light source being primarily cooled via conduction. The electrical conductor and the optical dispersing element being dimensioned and arranged within the unit such that the electrical conductor does not materially impede transmission of light generated by the light source to the outside of the device. The electrical conductor transmitting electrical and thermal energy received from the light source away from the unit.
