Abstract

System for controlling the operation of a lamp in multiple operational modes.

Claims

1. A method of operating a lamp, comprising:

receiving a first operation mode trigger; and

initiating the first operation mode in response to receiving the trigger if the lamp has operated continuously in a second operation mode for at least a predetermined duration;

wherein the first operation mode is a multi-level operation mode.

2. An apparatus for controlling a lamp, comprising:

means for receiving a first operation mode trigger; and

means for initiating the first operation mode in response to receipt of the trigger if the lamp has operated continuously in a second operation mode for at least a predetermined duration;

wherein the first operation mode is a multi-level operation mode.

3. An apparatus for controlling a lamp, comprising:

a receiver configured to receive a wireless signal to trigger a first operation mode; and

a controller configured to initiate the first operation mode upon receipt of the trigger if the lamp has operated continuously in a second operation mode for at least a predetermined duration;

wherein the first operation mode is a multi-level operation mode.

4. A method of operating a node comprising a lamp, comprising:

if a burn-in time expires when a new lamp burn-in state is active, transitioning to a start-to-high state;

if a start-to-high timer expires when the start-to-high state is active, transitioning to a heartbeat state and;

if a heartbeat timer is 0, deactivating a lamp relay by setting a 0-10V control to 0V;

or

if the heartbeat timer is not 0, activating the lamp relay by setting the 0-10V control to a last known value;

if a heartbeat message is received when the start-to-high state is active, refreshing the heartbeat timer and caching a 0-10V value;

if a new lamp burn-in time is reset via RF command when the start-to-high state is active, transitioning to the new lamp burn-in state and resetting the new lamp burn-in time;

if a panic start command is received when the start-to-high state is active, caching the start-to-high state and transitioning to a panic state; and

if an evacuation start command is received when the start-to-high state is active, caching the start-to-high state and transitioning to an evacuation state.

5. A system for operating a node comprising a lamp, comprising:

if a burn-in time expires when a new lamp burn-in state is active, means for transitioning to a start-to-high state;

if a start-to-high timer expires when the start-to-high state is active, means for transitioning to a heartbeat state and;

if a heartbeat timer is 0, means for deactivating a lamp relay by setting a 0-10V control to 0V;

or

if the heartbeat timer is not 0, means for activating the lamp relay by setting the 0-10V control to a last known value;

if a heartbeat message is received when the start-to-high state is active, means for refreshing the heartbeat timer and caching a 0-10V value;

if a new lamp burn-in time is reset via RF command when the start-to-high state is active, means for transitioning to the new lamp burn-in state and resetting the new lamp burn-in time;

if a panic start command is received when the start-to-high state is active, means for caching the start-to-high state and transitioning to a panic state; and

if an evacuation start command is received when the start-to-high state is active, means for caching the start-to-high state and transitioning to an evacuation state.

6. A method of operating a lamp, comprising:

receiving a first operation mode trigger; and

initiating the first operation mode in response to receiving the trigger if the lamp has operated continuously in a second operation mode for at least a predetermined duration;

wherein the first operation mode is a multi-level operation mode;

wherein the second operation mode comprises a full power operation mode;

wherein the predetermined duration comprises about 15 minutes after a most recent power interruption;

wherein the lamp comprises at least one of a photo sensor and a motion sensor;

wherein the multi-level operation mode comprises energizing the lamp in response to a detected ambient lighting level to substantially compensate for a difference between the detected ambient lighting level and a lighting level attainable when the lamp is operated at full power to provide full light output;

wherein the lamp comprises one of a plurality of lamps within a zone, and wherein the multi-level operation mode comprises energizing each of the lamps in response to a detected ambient lighting level to substantially compensate for a difference between the detected ambient lighting level and a lighting level attainable when the lamps are each operated at full power to provide full light output; and

wherein the multi-level operation mode trigger is indicative of motion detected in a zone associated with the lamp.

7. An apparatus for controlling a lamp, comprising:

means for receiving a first operation mode trigger; and

means for initiating the first operation mode in response to receipt of the trigger if the lamp has operated continuously in a second operation mode for at least a predetermined duration;

wherein the first operation mode is a multi-level operation mode;

wherein the second operation mode comprises a full power operation mode;

wherein the predetermined duration comprises about 15 minutes after a most recent power interruption;

wherein the lamp comprises at least one of a photo sensor and a motion sensor;

wherein the multi-level operation mode comprises energizing the lamp in response to a detected ambient lighting level to substantially compensate for a difference between the detected ambient lighting level and a lighting level attainable when the lamp is operated at full power to provide full light output;

wherein the lamp comprises one of a plurality of lamps within a zone, and wherein the multi-level operation mode comprises energizing each of the lamps in response to a detected ambient lighting level to substantially compensate for a difference between the detected ambient lighting level and a lighting level attainable when the lamps are each operated at full power to provide full light output; and

wherein the multi-level operation mode trigger is indicative of motion detected in a zone associated with the lamp.

8. An apparatus for controlling a lamp, comprising:

a receiver configured to receive a wireless signal to trigger a first operation mode; and

a controller configured to initiate the first operation mode upon receipt of the trigger if the lamp has operated continuously in a second operation mode for at least a predetermined duration;

wherein the first operation mode is a multi-level operation mode;

wherein the second operation mode comprises a full power operation mode;

wherein the predetermined duration comprises about 15 minutes after a most recent power interruption;

wherein the lamp comprises at least one of a photo sensor and a motion sensor;

wherein the multi-level operation mode comprises energizing the lamp in response to a detected ambient lighting level to substantially compensate for a difference between the detected ambient lighting level and a lighting level attainable when the lamp is operated at full power to provide full light output;

wherein the lamp comprises one of a plurality of lamps within a zone, and wherein the multi-level operation mode comprises energizing each of the lamps in response to a detected ambient lighting level to substantially compensate for a difference between the detected ambient lighting level and a lighting level attainable when the lamps are each operated at full power to provide full light output; and

wherein the multi-level operation mode trigger is indicative of motion detected in a zone associated with the lamp.
