Electrodeless discharge lamp |
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.
