Abstract

A cordless light assembly comprises a remote control unit (9) and light units (1), each comprising a light source (3), an electric power storage device (7) for driving the light source and a. switching unit (5). When the switching units receive a wirelessly transferred signal. from the remote control unit the power to the respective light sources are switched on and they start to emit light for only a predetermined time period after which, if no signal from the remote control unit is received, they stop to emit light. If a signal is received during the predetermined time, the light sources continue to emit light during a new time period. In receiving the signal, a voltage at a control terminal (12) of a controllable switch (11) in a light unit can be made to be sufficient to control the switch to a conducting state, this voltage decreasing gradually to eventually not being sufficient to control the switch to the conducting state. The signal from the remote control unit can be inductively transferred in a transformer coupling, the remote control unit having a primary coil (21) and the light units secondary coils (13).
