摘要： An ergonomic and energy-saving dimmable fluorescent lighting system using a distributed network (138) of lighting controls and control power sources. A plurality of controls (84) share a proportional-response control line (58) with a default value, wherein the control requesting the largest deviation from the default value prevails. Certain controls (124) may additionally share a polling line (126), in which the controls must agree on a value, before it can be requested on the proportional-response control line. Interactions between controls on the network provide for a method to control the total illumination on a scene, including both artificial (94) and natural (96) light, down to the light level where only natural light (96) is present. Unidirectional control nodes (86) allow a first network to exert control on a second network, without affecting the control levels in the first network. Thereby, hierarchical network control can be established. In addition, the method provides for network power to energize the control network (63), derived either from the lighting ballasts (52) or from external network-compliant power sources (192) strategically located in the network. A self-energizing contactor (80) switches power to the lighting system (56).

摘要： The present invention relates to a field emission device. More specifically, the present invention may prohibit unnecessary voltage from being applied to an anode electrode during non-operating time that no voltage is applied to a gate electrode to reduce driving power, prohibit electrons from being emitted with unnecessary high voltage which is applied to the anode electrode to increase luminous efficiency, and reduce a time that unnecessary high voltage is applied to the anode electrode to extend life time of the field emission device, by applying AC voltage to the anode electrode to correspond to a time that voltage is applied to the gate electrode and a type of voltage which is applied to the gate electrode. Therefore, the present invention comprises a front substrate and a rear substrate which are disposed at a certain distance and opposite to each other; at least one or more cathode electrodes formed on said rear substrate; at least one or more gate electrodes formed to be distant from said cathode electrodes and to be insulated with said rear substrate; emitters formed on the upper surfaces of said cathode electrodes; an anode electrode formed on said front substrate toward said rear substrate side; a fluorescent layer formed on said anode electrode; a first voltage application means for applying an AC voltage to said anode electrode; and a second voltage application means for applying an AC voltage to said gate electrode, wherein the AC voltages being applied to said anode electrode and said gate electrode are synchronized.
