無電極放電灯装置。 An electrodeless discharge lamp in which a discharge material is enclosed in a bulb-shaped bulb and a phosphor is coated on the inner surface of the bulb, an induction coil wound around the outer circumference of the bulb, and a high-frequency generator that supplies high-frequency current to the induction coil. In an electrodeless discharge lamp device equipped with a printed circuit board on which a circuit is mounted, a cap is provided at the bottom of the bulb to be attached to a cap holder provided at a key point of the device body,
The above-mentioned induction coil is a conical air-core coil that opens upward, and the induction coil is made to stand on a printed circuit board by a pair of lead wires led out from one place of the above-mentioned induction coil and connected to a high frequency circuit, and the base is mounted on a base holder. An electrodeless discharge lamp device characterized in that the inner circumferential surface of the induction coil is in close contact with the outer circumferential surface of the bulb when it is attached to the bulb.
