20120056560 | DC POWER SOURCE UNIT AND LED LAMP SYSTEM - A DC power source unit | 03-08-2012 |
20120175956 | DC POWER SUPPLY FEEDING SYSTEM - According to one embodiment of a DC power supply feeding system, the system includes a DC voltage power supply that outputs a specified voltage by using a commercial AC power supply, a varying voltage power supply that generates power by using natural energy and outputs a varying voltage, and a reverse flow preventing elements that connects the DC voltage power supply and the varying voltage power supply in parallel while output sides are made to have same polarity, and supplies powers obtained from the DC voltage power supply and the varying voltage power supply to a load. When an amount of power generation of the varying voltage power supply is small, the power is intermittently supplied to the load. | 07-12-2012 |
20130002169 | LUMINAIRE - According to one embodiment, a luminaire includes a lighting circuit configured to light a light source with a power supply from the outside, an accumulated-lighting-time storing section configured to store accumulated lighting time of the light source, and a control circuit configured to control the lighting circuit in a set mode. The control circuit sets, if a pattern for turning on and off the power supply from the outside is a predetermined initial illuminance correction setting pattern, a mode in an initial illuminance correction mode for performing initial illuminance correction corresponding to the accumulated lighting time of the light source. The control circuit sets, if the pattern for turning on and off the power supply from the outside is a predetermined normal setting pattern, the mode in a normal mode for not performing the initial illuminance correction. | 01-03-2013 |
20130187563 | DIMMING DEVICE AND LIGHTING SYSTEM - According to one embodiment, a control section receives supply of control power from a control power supply section through a capacitive element and divides, a period of each half cycle of an alternating-current voltage into a first section, a second section, and a third section. In the first section, the control section subjects a switch section to conduction control to supply electric power to a load and stops a converting action of the control power supply section. In the second section, the control section subjects the switch section to non-conduction control to interrupt the power supply to the load and stops the converting action of the control power supply section. In the third section, the control section subjects the switch section to the non-conduction control to interrupt the power supply to the load and causes the converting action of the control power supply to operate. | 07-25-2013 |
20140277591 | Electrical Equipment and Communication Apparatus - A lighting apparatus includes a communication unit and a control unit. The communication unit performs master-slave type communication with the communication adaptor, outputs, as a master, a transmission request of a control signal to the communication adaptor which temporarily stores the control signal for controlling the lighting apparatus, transmitted from equipment connected to the network, and receives the control signal transmitted from the communication adaptor in response to the transmission request. The control unit electrically controls the lighting apparatus on the basis of the control signal received by the communication unit | 09-18-2014 |
20140285013 | Electrical Apparatus Control System - According to one embodiment, an electrical apparatus control system which is configured by a plurality of electrical apparatuses includes an output unit which is provided on at least one first electrical apparatus among the plurality of electrical apparatuses, and transmits an obtained result of an information obtaining unit which obtains environmental information; and a reception unit which is provided on at least one second electrical apparatus other than the first electrical apparatus among the plurality of electrical apparatuses, and receives the obtained result which is transmitted from the output unit. | 09-25-2014 |
20140324195 | Control System - According to one embodiment, a control system includes an electric apparatus and a control unit. The electric apparatus operates in a first mode which is controlled based on an instruction from a user and in a second mode in which operational status is automatically managed. The control unit disables the second mode when receiving an instruction to disable the second mode and operates the electric apparatus, which operates in the first mode and the second mode, in the first mode. | 10-30-2014 |
20150061519 | Control Apparatus, Control System, and Control Method - According to one embodiment, there is provided a control apparatus including a receiving section, a specifying section, and control sections. The receiving section receives a control signal. The specifying section specifies a control system corresponding to the control signal received by the receiving section. The control sections derive, according to the control system specified by the specifying section, control designated by the control signal received by the receiving section, and apply the derived control to a lighting device. | 03-05-2015 |
