Abstract: The invention relates to a luminaire (10) comprising illuminants (170) for generating light, and a control unit (110) for controlling the illuminants (170), and at least one further element (140), in particular an operator control element (143) or a sensor (142), for generating control information that influences the operation of the luminaire (10), wherein the control unit (110) is configured in such a way that a self-test is carried out after a supply voltage has been applied to the luminaire (10). Said self-test is carried out automatically and independently in an analysis mode of the luminaire (10), wherein the control unit (110) checks the luminaire (10) for the presence and/or the functionality of the at least one further element (140). Depending on the checking result, and the type of further unit (140) checked, the control unit (110) controls the illuminants (170) such that a temporally variable light emission (171) signals the checking result.
