CA 2230887

A light emitting device (1) has a tubular light emitting element (11) and a pair of bases (14) provided on both the ends of the tubular light emitting element (11). A contactor (24) which is electrically connected to the tubular light emitting element (11) protrudes from the base main part (22) of the base (14) perpendicularly to the tube axis of the base main part (22). A pair of retaining arms (27) extends from the base main part (22) on both the sides of the contactor (24) approximately parallel to the direction where the contactor (24) protrudes. The pair of the retaining arms (27) of the base (14) also serve as guards to protect the contactor (24) while the base (14) is not attached to a socket device (2), while the contactor (24) is transported and while the contactor (24) is attached to the socket device (2). Further, by engaging the pair of the retaining arms (27) with the socket device (2), the light emitting device (1) is held by the socket device (2).

L'invention concerne un dispositif émetteur de lumière (1) comportant un élément tubulaire (11) à émission de lumière et une paire de bases (14) ménagées sur les deux extrémités de l'élément tubulaire (11). Un contacteur (24), raccordé électriquement à l'élément tubulaire, fait saillie de la pièce principale (22) de la base (14), perpendiculairement à l'axe du tube de ladite pièce principale (22). Une paire de bras de retenue (27) s'étend de la pièce principale (22) sur les deux côtés du contacteur (24) approximativement parallèlement au sens dans lequel le contacteur (24) fait saillie. La paire de bras de retenue (27) de la base (14) sert également de dispositif de protection du contacteur (24) lorsque la base (14) n'est pas fixée à un dispositif de douille (2), lors du transport du contacteur (24) et lorsque le contacteur (24) n'est pas fixé au dispositif de douille (2). D'autre part, en mettant en contact la paire de bras de retenue (27) avec le dispositif de douille (2), le dispositif émetteur de lumière (1) est maintenu par le dispositif de douille (2).
