摘要： An electrodeless discharge lamp device comprises an induction coil, a pair of cores 1a, 1b, and thermal conductor 2. The cores 1a, 1b are configured to generate a high-frequency electromagnetic field for exciting a discharge gas with receiving a high frequency electric power. Each of the cores is arranged to give an overall circumference around which the induction coil is wound. The thermal conductor is formed into an approximately cylindrical shape and inserted into the space so as to be thermally coupled with the cores for radiating heat generated at the cores. The core has its inside face at least center portion of which is spaced radially from the thermal conductor by a predetermined distance.

摘要： A lighting apparatus includes a lighting circuit unit, a timer unit, a life judgment unit, a timing adjustment unit, and an indication unit. The lighting circuit unit is configured to activate a light source. The timer unit is configured to measure accumulated operation time of the lighting circuit unit. The life judgment unit is configured to store a first judgment time and a second judgment time longer than the first judgment time. The life judgment unit is configured to compare the accumulated operation time with the first judgment time and output a first judgment signal when the accumulated operation time becomes equal to the first judgment time. The life judgment unit is configured to compare the accumulated operation time with the second judgment time and output a second judgment signal when the accumulated operation time becomes equal to the second judgment time. The timing adjustment unit is configured to vary timing at which the life judgment unit outputs the first judgment signal. The timing adjustment unit is configured to vary timing at which the life judgment unit outputs the second judgment signal. The indication unit is configured to indicate, upon receiving the first judgment signal from the life judgment unit, a first level of the end of life with the light source kept turned on. The indication unit is configured to indicate, upon receiving the second judgment signal from the life judgment unit, a second level of the end of life. The second level of the end of life is later than the first level of the end of life.

摘要： In an electrodeless discharge lamp suitable for use at a place with unfavorable environmental conditions or at a place where lamp replacement is difficult, the replacement of a lamp unit is facilitated and the lamp unit is prevented from falling off from a power coupler unit even if there is component deterioration caused by long-term use. A metallic elastic member is provided near a position on a metallic heat conduction member of the power coupler unit that is farthest from an electromagnetic field generating portion. In addition to an ordinary coupling structure between the power coupler unit and a coupling member, the elastic member is engaged with the coupling member of the lamp unit. When the lamp unit is mounted on or removed from the power coupler unit, a bulb of the lamp unit is turned relative to the power coupler unit about the axis and moved forward/backward in the direction of the axis. This causes the elastic member to be elastically deformed by the coupling member and engaged to or separated from a coupling portion provided at the coupling member.
