PROBLEM TO BE SOLVED: To provide an electrodeless lighting device which can prevent excessive heating.SOLUTION: An electrodeless lighting device 10 comprises: a stabilizer 11 which supplies a power source to an electrodeless fluorescent tube L; an induction coil 12 which generates a magnetic field by electric conduction from the stabilizer 11 and lights the electrodeless fluorescent tube L; and a housing part 13a of a shade 13 which houses the stabilizer 11 on an inner part, is attached to an attachment plate 14 having the induction coil 12 as the bottom surface and, thereby, retains the electrodeless fluorescent tube L. A slit 131 which functions as a vent hole for emitting heat from the stabiliser 11 is disposed on the housing part 13a. A bottom surface of the stabilizer 11 is separated by a nut 11d which functions as a gap securing member from the attachment plate 14. A protrusion 142 protruded in a direction of the electrodeless fluorescent tube L is formed on the attachment plate 14, and the protrusion 142 is formed as such a reflection surface that an inclination surface 142b extended toward the surrounding from an apex reflects light emitted to the hole inner direction of the electrodeless fluorescent tube L annularly formed. |
