- at least one dissipative active element array,
comprising
a plurality of dissipative active elements, said at least one dissipative active element array packaged to be thermally separate from said controller,
wherein
- the PWM functionality is arranged to individually pulse width modulate a current flow through each of the LED strings,
- and, and
- each of said plurality of dissipative active elements is associated with a particular one of the plurality of LED strings and is arranged to limit the current flow of the pulse width modulated current that flows through the particular LED string to a value, said value responsive to a value output by said controller via said data transfer interface circuitry.
