Abstract: A lamp socket has a mover and a supporter. At an open position, the supporter supports the mover so that the mover does not prevent a lamp from being moved to or from a mounting position along a specified direction. When the lamp can be moved from the mounting position along the specified direction, the supporter supports the mover so that the contacts do not make contact with lamp pins, respectively. At the close position, the supporter supports the mover so that the mover prevents the lamp from being moved from or to the mounting position along the specified direction. If the mover is at the close position, and the lamp is in a posture by which it can be moved from the mounting position along the specified direction in case of the open position, the supporter supports the mover so that the contacts make contact with the pins, respectively.

Abstract: The lamp socket according to the invention demonstrates a housing (2) with a rotor (26). Contacts (15, 16), which demonstrate contact tags (17) that are resilient in the swivel direction, are mounted in the housing (2). The open ends (18) of the contact tags can support themselves on stopping means (31 to 34), which are moved by the rotor (26). In the support position, they are positioned on the ends (18) of the contacts (15, 16). When the lamp is rotated from its insertion position into its connected position, the support means (31 to 34) are distant from the ends (18) of the contacts (15, 16), however, so that the lamp can be rotated relatively freely without current. Only near the end of this rotational movement do cams provided on the support means (31 to 34) bump against the ends (18) of the contacts (15, 16) and force them radially inwards and clamp the contacts (15, 16) against the pins (45, 46) of the lamp.

Abstract: An adjustable support member for attaching fluorescent lamps to a light strip fixture body. The adjustable support member is easily adjusted to accommodate fixture bodies having a variety of widths, thereby simplifying the upgrading of existing light fixtures to use more energy efficient bulbs. The support member includes a generally planar support body having a pair of channels formed thereon, and a pair of angle brackets which may be slid into the respective channels to a desired width. The angle brackets are held at a desired width by the ratchet/pawl effect of mating detents formed on the support body and the angle brackets. The channels are formed by stamping generally L-shaped channel members integral with the support body material. A reflector having a center ridge is formed to have a mounting tab by cutting a generally U-shaped opening along the center ridge. The mounting tab is then easily flattened for attachment to the support body for installing the reflector as part of the fixture upgrade.
