Abstract
A lighting apparatus capable of improving amenity and energy-saving and controlling a lighting load as a user intends to do. The lighting apparatus is connected to a network and controlling the lighting load corresponding to information from the network, and the lighting apparatus further comprises an automatic mode for controlling the lighting load corresponding to the information from the network, a manual mode for controlling the lighting load independently of the information from the network, and a switching means for switching between the automatic mode and the manual mode.
Claims20
A lighting apparatus connected to a network and controlling a lighting load corresponding to information from said network comprising:
- a network interference circuit for sending and receiving signals to said network;
- and
- a switching means for switching between an automatic mode for controlling the lighting load corresponding to the information from said network and a manual mode for controlling the lighting load independently of the information from said network.
A lighting apparatus connected to a network and controlling a lighting load corresponding to information from said network comprising:
- an automatic mode for controlling the lighting load corresponding to the information from said network;
- a manual mode for controlling the lighting load independently of the information from said network;
- a switching means for switching between said automatic mode and said manual mode;
- and
- a network interface circuit for performing input and output communication of information to and from said network, wherein
- said network interface circuit performs input and output communication to and from said network with appropriate timing when said manual mode is set.
A lighting apparatus connected to a network and controlling a lighting load corresponding to information from said network comprising:
- an automatic mode for controlling the lighting load corresponding to the information from said network;
- a manual mode for controlling the lighting load independently of the information from said network;
- and
- a switching means for switching between said automatic mode and said manual mode;
- wherein when the lighting load in the lighting apparatus is put out irrespective of operation of said automatic mode and said manual mode, a time period until said lighting load is completely put out can be set by time information received from said network.
A lighting apparatus connected to a network to control a lighting load corresponding to information from said network, which comprises
- a memory means, wherein
- said lighting load is controlled by invoking control data for changing or altering brightness of lighting stored in said memory means based on information from a communication network.
A lighting apparatus connected to a network to control a lighting load corresponding to information from said network, which comprises:
- a sound load for outputting sound;
- and
- a sound load control means which controls said sound load based on the information from said network and outputs a control signal to said sound load.
A lighting control system, comprising:
- a lighting apparatus connected to a network to control a lighting load corresponding to information from said network, which comprises:
- a sound load for outputting sound;
- a sound load control means which controls said sound load based on the information from said network and outputs a control signal to said sound load;
- a home electric appliance and a sensor connected to the network;
- and
- wherein said lighting control system, said lighting apparatus receives information from said home electric appliance and said sensor through the network, and by linking with said home electric appliance and said sensor, through said received information a lighting load and said sound load in said lighting apparatus is controlled.
A home electric appliance which is connected to a network and controls a lighting load corresponding to information from said network comprising:
- a network interference circuit for sending and receiving signals to said network;
- an automatic mode to control the load corresponding to the information from said network;
- a manual mode to control the load independently of the information from said network;
- and
- a switching means for switching between said automatic mode and said manual mode.
