Patent

CA 2223378

A single terminal type discharge lamp is provided, which comprises: a burner; a socket; a tubular holder, to which the burner is fitted, provided in the socket along a predetermined direction in which the burner is to be aligned; and a tubular metal holder spring which is mounted to the holder for radially depressing the holder toward the burner with deflecting force; wherein the burner is adhered to the socket due to the melt of the holder caused by the heat of the holder spring owing to radio-frequency heating which is performed when the one end of the burner is fitted to the holder such that the burner attains a predetermined position. Accordingly, the number of parts and the number of manufacturing steps are both reduced, thereby reducing costs of the discharge lamp.

L'invention porte sur une lampe à décharge à borne unique comprenant : un brûleur; une douille; un raccord tubulaire, sur lequel le brûleur est fixé, monté dans la douille dans le sens prédéterminé avec lequel le brûleur doit être aligné; et un ressort de raccord métallique tubulaire monté sur le raccord afin d'enfoncer ce dernier radialement vers le brûleur au moyen d'une force déviante. La chaleur du ressort à raccord fait fondre le raccord, ce qui amène le brûleur à coller à la douille. Cette chaleur vient du chauffage à hautes fréquences obtenu lorsqu'une extrémité du brûleur est insérée de façon ajustée dans le raccord de manière à ce que le brûleur se place à une position prédéterminée. Par conséquent, le nombre de pièces et d'étapes de fabrication est réduit, ce qui diminue le coût de la lampe à décharge.
