Abstract: The present invention relates to a luminaire having at least one illuminant (6), a luminaire housing (1), and at least one operating device (4), arranged in the luminaire housing (1), for the at least one illuminant (6), wherein the operating device (4) has an antenna (5) for transmitting and receiving a radio signal, and the luminaire housing (1) has at least one slot antenna (2) that is coupled to the antenna (5) of the operating device (4) by means of radiation coupling, a waveguide, or a cavity resonator in order to transmit the radio signal to outside the luminaire housing (1).

Abstract: A device (1) of a lighting technology network (2) is provided. The device (1) comprises one or more antenna units (102) being configured to communicate in respective preferential directions (103). The device (1) further comprises a processing unit (101). The processing unit (101) is configured to determine, in a commissioning phase of the device (1), an association of each further device (1) of the lighting technology network (2) with a respective preferential direction (103) of a respective one of the antenna units (102) that enables a radio connectivity between the device (1) and the respective further device (1). The processing unit (101) is further configured to communicate, in an operating phase of the device (1), to the further devices (1) using the associated one of the antenna units (102) in the associated preferential direction (103).

Abstract: A housing for a luminaire or an operating device for the luminaire, wherein the housing is configured to accommodate at least one electronic component and/or a light source, and comprising a conductive housing component (2). The housing includes at least one line (1, 1?, 1?, 1??, 1??) for transmitting electric high frequency signals or for transmitting and/or receiving radio waves. The transmission line is formed by arranging a dielectric layer (4, 4a, 4b, 9) and a conductor (3, 3 . . . 3c, 7) on the housing component (2) such that the conductive housing component (2) serves as a reference plane, and the conductive housing component (2) and the conductor (3, 3 . . . 3c, 7) sandwich the dielectric layer (4, 4a, 4b, 9).

Abstract: For the relative activation of a luminaire, actuation of an actuating element, particularly of a pushbutton, is detected. During actuation of the actuating element, the following steps are performed cyclically: ascertainment of a target control point (P_1, P_2) that corresponds to one of a plurality of sampling points (61, 62) encountered sequentially during the actuation; generation of a control command (71, 72) on the basis of the target control point (P_1, P_2); and issuing of the control command (71, 72) in order to reach a sampling point (61, 62) corresponding to the target control point (P_1, P_2) at a predefined change-over time (68). During continued actuation of the actuating element, a predefined period of time (68) is allowed to pass after a control command (71) is issued before a further control command (72) is issued in order to reach another sampling point (62) that corresponds to a further target control point (P_2).

Abstract: For the relative activation of a luminaire, actuation of an actuating element, particularly of a pushbutton, is detected. During actuation of the actuating element, the following steps are performed cyclically: ascertainment of a target control point (P—1, P—2) that corresponds to one of a plurality of sampling points (61, 62) encountered sequentially during the actuation; generation of a control command (71, 72) on the basis of the target control point (P—1, P—2); and issuing of the control command (71, 72) in order to reach a sampling point (61, 62) corresponding to the target control point (P—1, P—2) at a predefined change-over time (68). During continued actuation of the actuating element, a predefined period of time (68) is allowed to pass after a control command (71) is issued before a further control command (72) is issued in order to reach another sampling point (62) that corresponds to a further target control point (P—2).
