摘要： A dielectric barrier discharge lamp lighting apparatus includes twenty-four dielectric barrier discharge lamps, and a ballast circuit for lighting the twenty-four dielectric barrier discharge lamps which includes a DC power supply, an inverter circuit, a step-up transformer, and a lighting lamp number detecting circuit. The lighting lamp number detecting circuit detects the number of normally lighting dielectric barrier discharge lamps based on a first peek appearing right after polarity change of an approximate rectangular wave provided from the step-up transformer. When the detected number is less than a predetermined value, the operation of the ballast circuit is controlled to be stopped.

摘要： An electrodeless discharge lamp includes an induction coil that includes a core and a winding wound around the core and generates an electromagnetic filed inside a bulb, an insert portion provided inside the core, and a plane portion that releases heat from the insert portion to the outside of a case. A tolerance in the inductance of the induction coil is reduced by spacing the end portion of the core on the side of the plane portion apart from the plane portion, which makes reliable start-up possible.

摘要： A pair of internal electrodes are disposed at both ends of a lamp. A first voltage including a positive DC voltage superimposed on a substantial rectangular waveform voltage is applied to one of the internal electrodes. A second voltage including a negative DC voltage superimposed on the substantial rectangular waveform voltage is applied to the other internal electrode. The dark portion occurring substantially at the center in the longitudinal direction of the lamp becomes invisible, so that the brightness distribution is improved.

摘要： An electrodeless discharge lamp with a first coupling member includes a translucent discharge vessel in which a discharge gas is enclosed. A bobbin that includes a coil holding part for an induction coil and a vessel mounting part with a second coupling member is formed as a single piece. The coil holding part holds the induction coil on an outer surface thereof and is placed in proximity to the discharge vessel. The first and second coupling members are complementary and engage to mount the discharge vessel on the vessel mounting part of the bobbin to assure a long life and a positioning accuracy of the discharge vessel and the induction coil thereof.

摘要： The invention provides a self-ballasted fluorescent lamp provided with a function for operating normally when the self-ballasted fluorescent lamp is inadvertently connected to a lighting fixture provided with a light bulb dimmer if the dimmer is at the maximum level, and with a function for reliably stopping operation of the ballast circuit if the dimmer is in a dimmed state and thereby latch the lamp in an unlit state and protect the ballast circuit. Even if the self-ballasted fluorescent lamp is connected to a power source via a light bulb dimmer, when a current detected by a current detection circuit exceeds a predetermined current value, a stop circuit stops operation of an inverter circuit and latches it in that stopped state in order to maintain the self-ballasted fluorescent lamp in an unlit state.
