LIGHTING SYSTEM AND METHOD OF MANUFACTURE

摘要

A lighting system comprises a circuit board (30) which carries a lighting circuit comprising a plurality of lighting elements (72). The surface of the circuit board (30) carrying the lighting elements is at least partially reflective. A spacer layer (70) is over the circuit board and a top reflector (82) is over the spacer layer. The spacer layer defines a light cavity air gap between the circuit board and the top reflector, and the top reflector and/or the circuit board is provided with an array of light out-coupling structures.
