Abstract:
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.

Abstract:
An oblate spheroidal arctube body geometry provides for a significant reduction in stress cracks and results in lamps that operate at greater than 400 watts for extended periods of time leading up to greater than 20,000 hours. Preferably, the major diameter (OD) ranges between approximately 20 and 40 mm. Wall thickness (T) is preferably on the order of approximately 1.0 to 3.0 mm. An aspect ratio defined as AR (major axial dimension/minor axial dimension) is preferably between 1.1 and 2.0. A radius of curvature (R1) between the spheroidal portion and the leg of the arctube body preferably ranges from—approximately 3 mm to 12 mm or which can be expressed as a curvature 1/R1 ranging from 0.08 to 0.33 mm−1.
Abstract:
An electrodeless discharge lamp is provided which prevents the problem of decrease in strength due to degradation of resin material, allowing secure fitting of a lamp part and a coupler member to a base even if it is used for a long time. A bulb containing a discharge gas and a coupler member for generating a high frequency electromagnetic field to excite the bulb are detachably fitted to each other via a base for fixing and supporting the bulb. The bulb and the base form a lamp part. The base comprises a base frame formed of a metal such as aluminum and a base cover formed e.g. of synthetic resin. The base frame has a coupler member fitting portion which is provided at a lower part thereof and fitted to the coupler member, wherein bulb fixing posts provided to stand on the coupler member fitting portion fix a bulb outer tube. Thus, the fitting portions of the lamp part and the coupler member to the base undergo less material degradation than a conventional one which uses a base of resin material.
