Abstract
A lighting fixture includes a light emitting diode (LED) light source, a clock module, and a controller configured to control one or more characteristics of a light emitted by the LED light source based on time information received from the clock module. The controller is further configured to determine a current time of a day from the time information received from the clock module.
Claims20
A lighting fixture, comprising:
- a light emitting diode (LED) light source;
- a clock module;
- and
- a controller configured to control one or more characteristics of a light emitted by the LED light source based on time information received from the clock module, wherein the controller is configured to determine a current time of a day from the time information, wherein the controller is configured to interpret a sequence of toggles of a power provided to the lighting fixture as indicating a reference time of the day at a time of a detection of the sequence of toggles, and wherein the clock module is configured to keep track of the current time of the day starting from the reference time of the day.

A lighting fixture, comprising:
- a light emitting diode (LED) light source;
- a crystal;
- and
- a controller configured to keep track of a current time of a day based on a signal from the crystal and to control one or more characteristics of a light emitted by the LED light source based on the current time of the day, wherein the controller is configured to interpret a sequence of toggles of a power provided to the lighting fixture as indicating a reference time of the day at a time of a detection of the sequence of toggles and wherein the controller is configured to keep track of the current time of the day starting from the reference time of the day.
1 more element
A lighting fixture, comprising:
- a light emitting diode (LED) light source configured to emit a light;
- a clock module;
- and
- an LED driver comprising a controller, wherein the LED driver is configured to provide power to the LED light source, wherein the controller is configured to control an amount of the power provided to the LED light source, wherein the controller is configured to control one or more characteristics of the light based on time information received from the clock module wherein the controller is configured to interpret a sequence of toggles of a source power provided to the lighting fixture as indicating a reference time of a day at a time of a detection of the sequence of toggles, and wherein the clock module is configured to keep track of a current time of the day starting from the reference time of the day.
