摘要： A converter (1) for operating an LED load is provided. The converter (1) comprises an actively switched power factor correction, PFC, circuitry (104-112), having a control circuitry (2-4) for controlling a switch (105) of the PFC circuitry (104-112). The control circuitry (2-4) is configured to control a switch-on timing of the switch (105) such that an output voltage (113, Vbus) of the PFC circuitry (104-112) is feedback-controlled in accordance with a nominal value (201). In a discontinuous conduction mode, DCM, the control circuitry (2-4) is configured to control an actual value (204, Toff_act) of the switch-on timing of the switch (105) in one or more switching cycles to be a time of a valley of a voltage across the switch (105) succeeding a nominal value (302, Toff_nom) of the switch-on timing of a control algorithm implemented by the control circuitry (2-4). The control circuitry (2-4) is further configured to control the actual value (204, Toff_act) of the switch-on timing of the switch (105) in one or more subsequent switching cycles being subsequent to the one or more switching cycles to be a time of a valley of the voltage across the switch (105) preceding the nominal value (302, Toff_nom) of the switch-on timing. This reconciles valley switching and avoidance of visible light flicker.

摘要： An LED converter for supply of an LED load (18) is provided. The LED converter comprises a switched resonant converter (1) having at least one switch (11, 12) controlled by a control unit of the switched resonant converter (1). The control unit is configured to control a switching operation of the at least one switch (11, 12) such that the switched resonant converter (1) supplies an adjustable constant current (17) to output terminals for the LED load (18). The control unit is further configured to generate the adjustable constant current (17) by alternatingly controlling the at least one switch (11, 12) with one of at least two different, and adaptable, switching frequencies (44, 45) at a time for a respective time period (54, 55), and by adjusting a relative duration of the time periods (54, 55). Thereby, a resolution of an output current of the LED converter for supply of the LED load (18) is improved, which is of particular relevance for dimming applications.

摘要： 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).
