Abstract
An incandescent lamp-reflector unit having a metal reflector in which, for increasing the reflecting surface, the neck aperture of the reflector is maintained as small as possible, is not flash-over-safe due to the small distance between bare parts of the neck of the reflector and the contact pins of the lamp. The unsafety is removed by causing the said distance to be larger than the smallest distance of the pins and the neck of the reflector by means of an insulating envelope of the pins and/or an insulating coating on and near the end face of the neck of the reflector.
