Title: Device for increasing the lifetime of the lamps and timers of a communal building lighting system
IPC: H05B37/02
Filed: 1986-06-06
Abstract: Device for increasing the lifetime of the lamps and timers of a communal building lighting system. The invention relates to a device which, inserted into an electrical circuit, makes it possible to operate permanent or intermittent lighting depending on the user's needs, thus reducing the number of pulses received by the lamps. The device is inserted into an electrical circuit 1 and comprises a clock 2 which, supplied with the electric current and programmed for permanent lighting, closes the first contact 3 which transmits the current to the coil 4 which engages the general contactor 5, which lights the lamps 6 permanently. When the clock 2 is programmed for intermittent lighting it leaves the first contact 3 open, this enabling the current to supply the timer: the coil 7 of the timer receives the current via push-buttons 8, this closing the contact of the timer 9 and transmitting the current to the lamps 6. The device according to the invention is more particularly intended for saving energy in communal building lighting systems.
