Abstract: To provide a lamp device that is a point light source, that withstands high pressure, and that produces high-intensity light, a high-frequency excitation point light source lamp device has been devised having a discharge vessel made of a transparent, non-conductive material and having an expanded part forming a discharge space and with tubules joined to the expanded part; at least one discharge concentrator, that concentrates the electrical field within the discharge space of the expanded part, which is supported in a tubule with an end within the discharge space; and a high-frequency supply external to the lamp for providing excitation energy that excites a discharge of the concentrator.
