    • 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. Measuring devices (200, 210, 220) are additionally specified which detect the checking result by measurement of operating parameters of the luminaire (10) and present this information preferably by way of a display (211, 221) of the measuring device (200, 210, 220). A method is likewise specified which includes checking the at least one further element (140) and controlling the illuminants (170) by means of the control unit (110).

    • The present invention relates to an elongate light (1) having: an elongate light carrier (2), which extends along a longitudinal axis (A), the light carrier (2) having a contact face (20) extending along the longitudinal axis (A); an elongate lighting means (3) with a main radiation direction (H), the lighting means (3) extending along the longitudinal axis (A) in order to bear against the contact face (20); an elongate light guide (4), with an end-face input region (40) facing the lighting means (3) for coupling in the light emitted by the lighting means (3), and also with an output region (41) for emitting the light coupled in via the input region (40); and a spring element (5), which is clamped in the light carrier (2) in such a way as to press the lighting means (3) against the contact face (20) and to orient the lighting means (3) in such a way that the end-face input region (40) is opposite the lighting means (3) as viewed in the main radiation direction (H), in order to couple light emitted in the main radiation direction (H) by the lighting means (3) into the light guide (4) via the end-face input region (40).
