Abstract

A lighting fixture includes a transceiver, a receiver, a storage, and a controller. The transceiver receives a radio command from a radio remote controller for operating the lighting fixture. The receiver receives an infrared command from an infrared remote controller for operating the lighting fixture. The storage stores identification information of the radio remote controller. The controller, if the identification information is stored in the storage, accepts a radio command that includes identification information same as the identification information stored in the storage, among radio commands received by the transceiver, and ignores the infrared command received by the receiver, and if no identification information is stored in the storage, accepts the infrared command received by the receiver.

Claims

1. A lighting fixture which receives a radio command from a radio remote controller for operating the lighting fixture, and an infrared command from an infrared remote controller for operating the lighting fixture, the lighting fixture comprising:

a transceiver which receives the radio command;

a receiver which receives the infrared command;

a storage for storing identification information of the radio remote controller; and

a controller which

if the identification information is stored in the storage, accepts a radio command that includes identification information same as the identification information stored in the storage, among radio commands received by the transceiver, and ignores the infrared command received by the receiver, and

if no identification information is stored in the storage, accepts the infrared command received by the receiver.

2. The lighting fixture according to claim 1, wherein

the controller makes the identification information stored in the storage unusable if the receiver receives an unp airing signal.

3. The lighting fixture according to claim 1, wherein

the controller

determines, immediately after the lighting fixture is powered on, whether the identification information of the radio remote controller is stored in the storage,

causes the lighting fixture to enter a pairing configuration mode if the controller determines that the identification information of the radio remote controller is not stored in the storage, and

in the pairing configuration mode, when the transceiver receives, from the radio remote controller, a pairing command which includes identification information and the receiver receives a pairing trigger signal from the infrared remote controller, stores the identification information included in the pairing command into the storage.

4. The lighting fixture according to claim 3, wherein

the controller

causes the lighting fixture to emit light in a first illumination mode if the controller determines that the identification information of the radio remote controller is not stored in the storage,

causes the lighting fixture to emit light in a second illumination mode if the controller receives the pairing command in the pairing configuration mode, and

causes the lighting fixture to emit light in a third illumination mode, after storing the identification information included in the pairing command into the storage.

5. A lighting system comprising:

lighting fixtures which receive a radio command from a radio remote controller for operating the lighting fixtures, and an infrared command from an infrared remote controller for operating the lighting fixtures;

the radio remote controller configured to operate in a pairing configuration mode in which the radio remote controller transmits, repeatedly for a predetermined time period, a pairing command which includes identification information of the radio remote controller, and a normal operation mode in which the radio remote controller transmits the radio command; and

the infrared remote controller which transmits the infrared command to at least one of the lighting fixtures, wherein

the lighting fixtures each include;

a transceiver which receives the radio command;

a receiver which receives the infrared command;

a storage for storing the identification information of the radio remote controller; and

a controller which

if the identification information is stored in the storage, accepts a radio command that includes identification information same as the identification information stored in the storage, among radio commands received by the transceiver, and ignores the infrared command received by the receiver, and

if no identification information is stored in the storage, accepts the infrared command received by the receiver.

6. The lighting system according to claim 5, wherein

the infrared remote controller emits, to a lighting fixture among the lighting fixtures, infrared light which has a light distribution that does not concurrently reach a lighting fixture adjacent to the lighting fixture.

7. A method performed by a lighting fixture which receives a radio command from a radio remote controller for operating the lighting fixture, and an infrared command from an infrared remote controller for operating the lighting fixture, the method comprising:

receiving the radio command;

receiving the infrared command;

determining whether identification information of the radio remote controller is stored in a storage included in the lighting fixture;

if the identification information is stored in the storage, among radio commands received, accepting a radio command that includes identification information same as the identification information stored in the storage and ignoring a radio command that includes identification information different from the identification information stored in the storage, and ignoring the infrared command; and

if no identification information is stored in the storage, accepting the infrared command received.

8. The method according to claim 7, further comprising

if the identification information of the radio remote controller is stored in the storage and an unpairing signal from the infrared remote controller is received, making the identification information of the radio remote controller stored in the storage unusable.
