The present invention relates to a method of and a vertical pumping device (1) for internally distributing Hg in a fluorescent tube body (3). The bottom (7) of the fluorescent tube body (3) is closed. The device (1) arranges, in a first position, a first solid body (9') comprising a predetermined first amount of bound Hg. The device (1) arranges, in a second position, a second solid body (9") comprising a predetermined second amount of bound Hg. A first release (E1) of the first amount of Hg is achieved in the fluorescent tube body (3) by gasification with heat and under pressure for purification of contaminant particles in the fluorescent tube body. A second release (E2) of the second amount of Hg is achieved in the fluorescent tube body (3) by gasification attained for the occluded mercury vapour of the fluorescent tube body (3).
The present invention regards a dampener to augment the mounting of a lamp (10, 10a, 10b) in a socket (80, 82) by resisting displacement of the lamp (10, 10a, 10b) relative to the socket (80, 82), the dampener (40, 50, 60, 70, 90, 100, 200) is made from a material able to absorb vibrations and to reduce or prevent vibrations in the lamp (10, 10a, 10b). The dampener (40, 50, 60, 70, 90, 100, 200) is made in one piece or more pieces, wherein each piece is interposable in whole or in part between the socket (80, 82) and the lamp (10, 10a, 10b) base to insulate the lamp (10, 10a, 10b) in whole or part against the vibration translated through the socket (80. 82) or surrounding air.
The present invention relates to a metal halogen lamp comprising, inside an outer casing (7), first (3) and second (5) arc tube members, which are electrically parallel-connected and are connected via conductive members (9) to a base part (11), each arc tube member having a first end (15), facing toward the top part (17) of the outer casing (7) opposite the base part (11), and a second end (19), facing toward the base part (11). The first arc tube member (3) is arranged closer to the top part (17) than the second arc tube member (5), and the second end (19) of the first arc tube member (3) and the first end (15) of the second arc tube member (5) adjoin an imaginary plane (P) defined substantially transversely to the center line (CL) of the outer casing (7), which center line extends from the top part (17) to the base part (11).
The invention relates to a metal halogen lamp comprising an elongated arc tube (3) enclosed in a transparent casing (5), wherein the arc tube (3) is made up of a hollow glass body (7) comprising two end portions( 9) and a middle portion (11), an electrode (13) is arranged on the respective end portion (9), which electrodes (13), each having an electrode end (15), upon connection to a power source and during operation of the metal halogen lamp (1), generate an arc (23) between them; and the glass body (7) encloses halogens (h) and metal atoms (m) and has a wall thickness which is thicker on the end portions (9) than on the middle portion (11). The thicker end portions (9) each have a length (L1) of at least one-third of the total length (L) of the arc tube (3).
The present invention relates to a compact fluorescent tube (1) designed for cold spaces, which compact fluorescent tube (1) comprises at least one fluorescent tube body (13) formed into a U-shape and comprising two fluorescent tube body legs (17), which latter have an interspace (19) between them and each comprise a base part (9), enclosing a cathode chamber (11), and a top part (15) facing away from the said base parts (9), which base parts are fixed to a socket part (3), comprising current feeder members (5) for electrical contact with the cathode chambers (11). An insulating member (21, 47, 55) is arranged on the top part (15) of the compact fluorescent tube and is configured with at least one insulating cavity (23, 49), which, during operation of the compact fluorescent tube (1), is heated by the self-produced heat of the compact fluorescent tube (1).
