Claim 0:
1. A lighting system comprising:
a first light-emitting device;
a second light-emitting device;
a bus line configured to:
transmit a first dimming signal to a first controller and to a second controller, wherein the first dimming signal is generated from a direct current (DC) dimming signal; and
transmit a second dimming signal to the first controller and to the second controller, wherein the second dimming signal is generated from an alternating current (AC) dimming signal;

the first controller configured to:
receive the first dimming signal;
receive the second dimming signal; and
transmit a third dimming signal to the first light-emitting device, wherein:
the third dimming signal is based on the first dimming signal or the second dimming signal; and
a brightness of the first light-emitting device is based on the third dimming signal; and

the second controller configured to:
receive the first dimming signal;
receive the second dimming signal; and
transmit a fourth dimming signal to the second light-emitting device, wherein:
the fourth dimming signal is based on the first dimming signal or the second dimming signal; and
a brightness of the second light-emitting device is based on the fourth dimming signal.
