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 apparatus comprises a housing and a first reflector. The first reflector is mounted beneath the light source and includes a plurality of segmented reflectors, each having at its top, a installation hole and at its bottom, an opening wider than the installation hole. A second reflector is positioned beneath the first reflector. The height of the second reflector causes a first light shielding angle defined by a straight line passing through the installation hole and the bottom edge of the corresponding segmented reflector to be larger than a second light shielding angle defined by a straight line passing through the bottom edge of the segmented reflector and the bottom edge of the second reflector.

摘要： A light-emitting device and an illumination apparatus are disclosed. A plurality of LED elements are connected in series between positive and negative lines, and first bypass capacitor is connected in parallel to the LED elements respectively. Each series circuit of a predetermined number of LED elements is connected in parallel to second bypass capacitors. As a result, with the negative power line set as a grounding point, the AC impedance at connection points of the series circuit of the LED elements against the ground is reduced. Thus, the erroneous lighting or “flicker” of each LED which otherwise might be caused by an external noise is prevented.
