Multiplexed segmented lighting lamina
Apparatus and methods for providing LED lighting on light tape and light sheet. A controller may provide lighting control data to one or more ICs on a segment of tape or sheet. The lighting control data may include a data packet. The data packet may include an address. The address may correspond to one or more of the ICs. The address may correspond to one or more LEDs on the segment. The address may correspond to one or more LEDs on a light tape. The address may correspond to one or more LEDs on a light sheet. The LEDs corresponding to the address may be controlled by a current regulator or regulators on a single IC. The LEDs corresponding to the address may be controlled by current regulators on different ICs.
