1. A lighting system, comprising:
- a light box housing including a light transmissive face, a back, and a plurality of sidewalls separating said face and said back;
a plurality of interconnected lighting units on at least one carrier in said light box housing and comprising conductors to provide an electrical signal to each of said units, each of said plurality of lighting units comprising;
a plurality of light emitting elements; and
a printed circuit board (PCB), wherein said plurality of light emitting elements are on said PCB and adapted to emit light substantially away from said PCB and toward said light transmissive face in response to said electrical signal; and
a mounting mechanism arranged to mount said plurality of lighting units to said light box housing, wherein light emitted from said plurality of lighting units has a light distribution pattern to form a substantially uniform light emission through said light transmissive face.

Abstract
A lighting system comprising a light box housing, a plurality of lighting units including a housing, a plurality of light emitting elements mounted on a PCB within the housing. The lighting units can also be interconnected in a daisy-chain configuration on at least one carrier, such that the lighting units form an array of lighting units. The array of lighting units adapted to be mounted within the light box housing, wherein the light box housing comprises one or more arrays of lighting units.

24. An array of lighting units, comprising:
-
at least one carrier; a plurality of lighting units mounted to said at least one carrier, wherein said plurality of lighting units are electrically connected to each other in a daisy-chain configuration, each of said lighting units comprising; a printed circuit board (PCB) coupled to said at least one carrier; a plurality of light emitting elements on at least one side of said PCB; and first and second electrical conductors coupled to said PCB and arranged to provide an electrical signal to each of said plurality of light emitting elements; wherein said at least one carrier is adapted to be flexible such that said at least one carrier can bend freely in many different directions; wherein said plurality of lighting units and said at least one carrier are adapted to be coiled to form a coiled array of lighting units. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
