Abstract
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.
