Abstract
A lighting unit has an input connector which has a first terminal arrangement which connects to a protection circuit to engage a lighting driver in an initial connection of the lighting unit () and the lighting driver (), and a second terminal arrangement which connects to a light source. The second terminal arrangement is adapted to engage the lighting driver later than an engagement of the first terminal arrangement to the light driver. The protection circuit () is adapted to operate earlier than an engagement of the light source () to the lighting driver (). The protection circuit prevents current surges from being delivered by the lighting driver at the time of connection of the lighting unit. The protection circuit is only applied temporarily, before direct connection is made between the light source and the lighting driver.
