Abstract

Abstract A light assembly is made up of a circuit board and a plurality of individual light units which can be installed on and removed from the circuit board to form a desired design or pattern. Each individual light unit includes an electro-luminescent light panel and a resilient contact arrangement which permits an electrical connection between the contacts in the individual light unit and contact terminals on the circuit board to be established by the act of mounting the individual light unit on the circuit board. The light unit itself may form a sub-assembly of a larger lighting arrangement, and each sub-assembly may include a plurality of individual light units arranged into groups, with each group having a different color.
