Abstract
A light fixture of a light system is configured to be dimmable using a dimming signal that is either a direct-current (DC) dimming signal or an alternating-current (AC) dimming signal. For example, a 0-10 volt DC dimming signal could be used, or a 120 volt AC dimming signal could be used. A dimming controller in the light fixture is configured to receive both a DC and an AC dimming signals and adjust a brightness and/or color of a light based on the dimming signal.
Claims20
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.

A lighting system comprising:
- a light-emitting device;
- and
- a controller configured to:
- receive a first dimming signal, wherein the first dimming signal is a direct current (DC) dimming signal;
- receive a second dimming signal, wherein the second dimming signal is an alternating current (AC) dimming signal;
- and
- transmit a third dimming signal to the light-emitting device, wherein:

A method for a lighting system comprising:
- receiving a first dimming signal, at a controller, wherein the first dimming signal is a direct current (DC) dimming signal;
- receiving a second dimming signal, at the controller, wherein the second dimming signal is an alternating current (AC) dimming signal;
- and
- transmitting, using the controller, a third dimming signal to a light-emitting device, wherein:
- the third dimming signal is based on either the first dimming signal or the second dimming signal but not both at the same time;
- and
- a brightness of the light-emitting device is based on the third dimming signal.
