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.

摘要： An electrodeless discharge lamp apparatus is provided which is increased in heat dissipation, making it possible to adapt to an increase in output of the apparatus. The electrodeless discharge lamp apparatus comprises a bulb containing a discharge gas and a coupler accommodated in a cavity formed in the bulb for generating a high frequency electromagnetic field. The coupler has: an induction coil; a core inserted into the coil; a heat conductor for conducting heat generated from the coil and the core; and a bobbin made of resin which accommodates the core and the heat conductor therein, and which has the coil wound therearound. The bobbin is designed to be separated in a radial direction of the coil, so that it is possible to separately mold the respective parts of the bobbin. Thus, it is not necessary to form, in the bobbin, a draft angle which has been necessary in the prior art when molding a tubular-shaped bobbin, and it is possible to make the thickness of the bobbin thin and uniform, so that the proportion of the bobbin in the volume of the cavity can be reduced to increase the proportion of the heat conductor.

摘要： An electrodeless discharge lamp comprising: an airtight container bulb made of a transparent material and enclosing a discharge gas; and a coupler (coil assembly body), contained in a cavity formed in the bulb, for generating a high frequency electromagnetic field by conducting a high frequency current in a coil to excite the discharge gas so as to emit light, wherein the coupler comprises: a pipe-shaped cylinder formed of a thermal conductor for heat release; a skeleton-shaped bobbin mounted on an outer surface of the cylinder along an axial direction of the cylinder; a core made of a soft magnetic material provided at an opening formed by the skeleton of the bobbin and being in substantial surface contact with the cylinder; and a coil wound around a surface of the skeleton-shaped bobbin and the core. Thus, the core provided at the opening formed by the skeleton is in substantial surface contact with the cylinder for heat release, so that heat received by the coil from the heat-generating bulb is directly exhausted to the cylinder through the core.

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.
