Abstract
An elongated lamp unit in which electrically conductive connecting terminals provided at both ends of the lamp are electrically connected by force fitting into metal contact clamps arranged opposite each other. The electrically conductive connecting terminals extend endwise beyond flat portions formed on each end of an elongated lamp bulb and are electrically connected with a filament disposed in the bulb, and have surface-to-surface contact with the metal contact clamps. The metal contact clamps which receive the electrically conductive connecting terminals are connected with a power supply and comprise a pair of electrically conductive metal pieces opposite each other, these metal pieces having upper ends defining an insertion opening portion which receives the electrically conductive connecting terminal and limits at an inner portion of the electrically conductive contact the inserted position of the electrically conductive connecting terminal.
