摘要： In a power supply device according to one embodiment, a reference signal (Vref1), which changes from a value corresponding to a maximum current in a full lighting state to that corresponding to a minimum current in case of a deepest dimming depth, and a reference signal (Vref2), which changes from a value corresponding to a load voltage at the time of a maximum current in a full lighting state to that corresponding to a minimum current in case of the deepest dimming depth, are prepared in accordance with dimming depths of a dimming signal. In a shallow dimming depth region close to a full lighting state, the reference signal (Vref1) is selected to apply constant-current control to light-emitting diodes in a current control mode. In a deep dimming depth region, the reference signal (Vref2) is selected to apply constant-voltage control to the diodes in a voltage control mode.

摘要： A lighting device may include a substrate attached to one edge side of a radiator and a cover may be attached to cover the substrate. Heat-radiating fins may be provided on the other edge side of the radiator and an air-cooling unit may be rotatably provided inside the heat-radiating fins, thereby enabling freely rotation. In one or more examples, a case storing a circuit part is attached to the other edge side of the radiator and a cap is provided to the case. By the air flow from the air-cooling unit, the heat-radiating fins are caused to be a part of the ventilation path to allow for ventilation of the inside of the radiator.

摘要： A layer 2 switch network system includes a terminal, an edge switch, and a Radius server that notifies the edge switch of a temporary MAC address allocated to the terminal. The edge switch stores therein swap data for associating the temporary MAC address with a real MAC address. When receiving a MAC frame from the terminal, the edge switch replaces the real MAC address of a source set in the MAC frame with the temporary MAC address of the source. When transmitting a MAC frame to the terminal, the edge switch replaces the temporary MAC address of a destination set in the MAC frame with the real MAC address of the destination.

摘要： A lighting fixture includes a light-emitting section composed of a plurality of semiconductor light-emitting devices arranged separated from one another on a planar substrate and a lighting control section configured to control lighting of the semiconductor light-emitting devices of the light-emitting section. The light-emitting section is attached at a front of a fixture main body, and a convection generation section configured to generate convection is provided at a back of the fixture main body. The convection generation section generates convection and promotes heat radiation. With the configuration, even if the lighting fixture is installed to abut on a ceiling surface, the effect of radiating heat generated by the semiconductor light-emitting devices can be ensured.

摘要： A lighting device includes a light source configured to radiate light toward a floor from a ceiling, a reflecting mirror provided around the light source, and shading angle setting element configured to define a range in which the light from the light source is radiated by setting a shading angle with respect to the light radiated from the light source. The light source, the reflecting mirror and the shading angle setting element are covered by a translucent cover. The translucent cover has an in-line transmittance. An in-line transmittance of the translucent cover of a position corresponding to an optical axis of the light source and an in-line transmittance of the translucent cover of a position deviated from the optical axis are different from each other.

摘要： In an electric-circuit-containing box including an upper case having a side provided with a hole and a lower case having a side provided with a projection to be fitted in the hole, moisture is prevented from entering the box from the hole of the upper case by a capillary phenomenon. A recess separate from an inside surface of an upper case is provided around a projection of a side of a lower case. Thus, a specified interval is ensured between the periphery of the projection of the side of the lower case and the hole of the upper case. Accordingly, even if moisture attached to an upper part of the upper case flows to the vicinity of the hole 1b along an outside surface of the upper case, there does not occur a state that the moisture passes through between both the cases from the hole by the capillary phenomenon and enters inner spaces of both the cases and in which a board and electronic parts are contained.
