Abstract

PURPOSE:To reduce the deterioration of a flux of light in a lighting action by using an electrode, which has an electron emitter which in turn contains a specific material, to increase the adherence of the electron emitter to constitutive elements of the electrode. CONSTITUTION:An electrode consists of an electrode core 15 which is made of a heat resisting metal, an inner coil 16, an outer coil 17 and an electron emitter 18. The electron emitter 18 contains neodymium oxide and at least one rare earth metal oxide selected from the oxides of cerium, praseodymium, samarium, europium, gadolinium, terbium, holmium, erbium, thulium, ytterbium and lutetium.
