1. A lighting system, comprising:
- a plurality of strings of solid state lighting devices arranged in a first direction and positioned at intervals in at least one second direction;
a current supply circuit configured to selectively supply a plurality of on-state drive currents to the plurality of strings responsive to a plurality of control signals; and
a control system configured to receive a user input and to selectively provide control signals to the current supply circuit responsive to the user input to selectively drive the plurality of strings, the control system further including firing logic configured to determine a firing order of the plurality of strings.

Abstract
Provided are systems and methods for controlling a solid state lighting panel. A system according to some embodiments of the invention includes a controller that provides control signals to current drivers that are configured to provide current to multiple solid state lighting devices. The system also includes a sequence generator that generates a firing sequence for firing multiple strings of slid state lighting devices.

17. A method for controlling a plurality of strings of solid state lighting devices configured to extend in a first direction and to be arranged in substantially adjacent positions relative to one another in a second direction that is different from the first direction, the method comprising:
-
receiving an input from a user; and supplying, based in part on the input from the user, a plurality of pulsed drive currents to the plurality of strings in a non-spatially-sequential firing order. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

53. A system, comprising:
-
a plurality of strings of solid state lighting devices arranged in a first direction and positioned at intervals in a second direction that is substantially orthogonal to the first direction; a current supply circuit configured to selectively supply a plurality of on-state drive currents to the plurality of strings responsive to a plurality of control signals; a control system configured to receive an input from a user and, responsive to the input, to selectively provide control signals to the current supply circuit to selectively drive the plurality of strings, the control system further including firing logic configured to determine a firing order of the plurality of strings; and wherein the firing logic is configured to drive the plurality of strings in a spatially non-adjacent, non-sequential firing order and/or to drive the plurality of strings at different times for at least a subset of the plurality of strings. - View Dependent Claims (54, 55, 56, 57)
