    摘要: Devices (1) for driving light sources (5) comprise drivers (2) operable in different modes and controllers (3) for, in response to detections of values of input voltages supplied to the devices (1), bringing the drivers (2) in one of the different modes. Such devices (1) can be used solely and in series and parallel combinations. In case the value of the input voltage is smaller / larger than a threshold value, a first / second mode is selected. The first mode is a preset-mode, the second mode is a feedback-mode. A combination of the light source (5) and the driver (2) may show a constant-resistor-load-behavior in the preset-mode. The device (2) may comprise a switch (25) that in the preset-mode is operated at a constant conducting time and that in the feedback-mode is operated in response to feedback- information derived from the light source (5). At start-up, the driver (2) may be kept deactivated during a time-interval.

    摘要: The present invention relates to an LED retrofit lamp (1) for being connected to a high frequency electronic ballast (26), the high frequency electronic ballast (26) being adapted for providing a voltage and a current to the LED retrofit lamp (1). The LED retrofit lamp (1) comprises an LED unit (4), an adapting unit (30) for adapting the voltage and the current provided by the high frequency electronic ballast (26) to a voltage and a current for operating the LED unit (4), a detecting unit (40) for detecting an electrical value that depends on the current provided by the high frequency electronic ballast (26), and a ballast protection unit (60) for performing, in dependence of the detected electrical value, an operation for protecting the high frequency electronic ballast (26) from an overcurrent situation. This allows avoiding an unsafe situation, such as when the high frequency electronic ballast (26) is overheated.

    摘要: The present invention relates to an LED retrofit lamp adapted for operation with an alternating current. The LED lamp comprises an LED unit, first and second switching devices (e.g., first and second relays), a startup voltage supply unit (1010) coupled in parallel to the first switching device, an ignition detection unit (1020) coupled in parallel to the second switching device, and a switch drive unit (1030) for setting the first and second switching devices to a conducting state. If one of the first and second switching devices is shorted either no startup supply voltage or no detection signal is provided, such that the failure is indicated externally to a user.

    摘要: Arrangements comprise drivers (1) for driving light circuits (5), receivers (2) for in response to receptions of wireless signals controlling the drivers (1), and supplies (3) for providing first feeding signals for feeding the receivers (2) during off-states of the drivers (1). The drivers (1) themselves provide second feeding signals for feeding the receivers (2) during on-states of the drivers (1). Devices (6) such as lamps in the form of retrofit tubes comprise the arrangements and the light circuits (5). The light circuits (5) may comprise light emitting diodes. The arrangements may receive AC signals from ballasts (7), and both feeding signals may be DC signals. The supplies (3) may comprise voltage dividers (31, 32) with first capacitor circuits (31) to limit currents entering the supplies (3) for given frequencies of the AC signals and voltage definition circuits (32) for defining voltage signals present across the voltage definition elements (32). Both feeding signals may be supplied via elements (33, 35) with diode functions.
