Abstract
The invention relates to a luminaire (10) or electrical unit which is intended to be supplied with voltage via a DC supply circuit (90) and has means for power consumption (19) from the DC supply circuit (90), a connection element (20) for coupling to the DC supply circuit (90) in order to electrically connect the means for power consumption (19) to the DC supply circuit, and a switching element (30), by means of which the luminaire (10) or the electrical unit can be switched to electrically load-free before the connection element (20) is coupled to the DC supply circuit (90) or before the coupling is released.
Claims14
A luminaire (10) supplied with a high-voltage greater than 230V via a DC supply circuit (90), wherein the luminaire (10) has:
- means for power consumption (19) from the DC supply circuit (90), said means for power consumption comprising a driver and one or more LED lamps wherein the driver converts the high DC voltage of greater than 230V into a voltage suitable for operation of the one or more LED lamps;
- a connection element (20) for coupling to the DC supply circuit (90) in order to electrically connect the means for power consumption (19) to the DC supply circuit, or decoupling from the DC supply circuit (90) in order to electrically disconnect the means for power consumption (19) to the DC supply circuit;
- and
- a switching element (30) designed to interrupt or close a control line (27) leading to the driver such that the driver switches to a load-free standby mode when an interruption of the control line (27) or a closure of the control line (27) is detected;
- wherein the connection element (20) can be connected to and disconnected from the DC supply circuit (90) supplying the high-voltage greater than 230V when the driver is in load-free standby mode to avoid the risk of electrical arcing while connecting or disconnecting.
