Lamp having a rotatable base

摘要

The invention relates to an electric lamp (1) comprising at least one vessel (3) for producing and emitting visible electromagnetic radiation, a base (9) for securing and making electrical contact with the lamp (1) in a luminaire fitting, and a connecting part which connects the base to one of the remaining parts of the lamp (1). The connecting part is in this case in the form of a rotationally symmetrical rotary device (8) which makes it possible for the remaining parts of the lamp (1) to be rotated with respect to the base (9), when the base (9) is secured in the fitting, about the axis of the lamp (1).
