    • An electrical lamp system is provided that comprises a base unit and a lamp unit for attachment to the base unit. The base unit includes a housing to be fixed to a wall or ceiling and a plurality of contact terminals that are arranged to contact corresponding contact terminals of the lamp unit when attached. A plurality of connection terminals secured to the base housing are adapted for connection to wires fed to the base unit such that wires connected to the connection terminals can power the lamp unit via the base unit contact terminals. The lamp unit includes a lamp housing an electrical lamp secured to the housing, a plurality of contact terminals arranged to contact said contact terminals of the base unit. The system includes locating means arranged to locate the lamp unit in a first position against the base unit in which the lamp unit is permitted to be separated from the base unit by translation of the lamp unit in a direction away from the base unit along a separation axis. The system also includes guide means that guide rotation of the lamp unit against the base unit about said axis from said first position to a second position, the second position being a position in which said contact terminals of the base unit are in electrical contact with said contact terminals of the lamp unit. In the second position, attachment means attaches the lamp unit to the base unit by preventing separation of the lamp unit from the base unit by translation of the lamp unit along said axis.
    • 提供一种电灯系统,其包括基座单元和用于附接到基座单元的灯单元。 基座单元包括固定到墙壁或天花板的壳体和多个接触端子,其被布置成在附接时与灯单元的相应接触端子接触。 固定到基座的多个连接端子适于连接到馈送到基座单元的导线,使得连接到连接端子的电线可以经由基座单元接触端子为灯单元供电。 灯单元包括容纳固定到壳体的电灯的灯,布置成接触基座单元的接触端子的多个接触端子。 该系统包括定位装置,其布置成将灯单元定位在第一位置抵靠基座单元,其中灯单元允许通过沿着分离的方向沿着远离基本单元的方向平移灯单元而与基座分离 轴。 所述系统还包括引导装置,其引导灯单元绕所述轴线从所述第一位置转动到第二位置,所述第二位置是所述基座单元的所述接触端子与所述第一位置电接触的位置, 灯单元的接触端子。 在第二位置,附接装置通过防止灯单元沿着所述轴的平移而防止灯单元与基座单元分离,从而将灯单元附接到基座单元。
