Abstract: An inter-terminal connection structure electrically connecting terminal portions via a conductive component. The conductive component includes a conductive member having connection portions that are fastened so as to be connected to the respective terminal portions, and a case having insulation properties while accommodating the conductive member, an insulating cover covering at least one of the terminal portions and the connection portions, an opening window provided to the insulating cover and exposing at least one of the terminal portions and the connection portions, and a relay portion provided to the connection portion or the terminal portion fastened to the at least one of the terminal portions and the connection portions covered by the insulating cover while being inserted through the opening window to be connected to the at least one of the terminal portions and the connection portions.

Abstract: A highly safe fluorescent lamp is disclosed, in a mixed layer having couplings of phosphors and a metal oxide such as yttrium oxide is formed on the inner surface of a glass bulb. The couplings of the mixed layer strongly couples the grains arranged in crosslinked state between the phosphor grains of the phosphor material. A first thin film of the metal oxide is formed between the glass bulb and the mixed layer. A second thin film of the same metal oxide is formed on the inner surface of the mixed layer nearer to the bulb center. The amount of mercury sealed in the glass bulb thus is reduced, thereby minimizing the mercury consumption which has so far been the problem against environmental protection.
