摘要： An illumination device (1) comprises: at least one low-power light source (50); a power input stage (20) suitable for receiving AC low voltage from an electronic transformer (ET); a power buffer stage (30) having an input (31) connected to the input stage output (29); a driver (40) for driving the light source and receiving electric power supply from the power buffer stage. The power input stage generates output current pulses for charging the power buffer stage at a relatively low frequency, and during each output current pulse, the power input stage draws input current, the input current always having a current magnitude higher than a minimum load requirement of the electronic transformer.

摘要： A LED retrofit driver circuit (3) is provided, comprising at least an input (6) for receiving an operating voltage from a power supply (2), an output (8) for connection to one or more LED units (5), a power converter (7) connected with said input (6) and said output (8) and configured to provide a lamp current (50) at said output (8) during operation in at least a first and a second operating state. To provide a versatile circuit (3), allowing operation with a variety of power supplies and under various load conditions, in said first operating state, the power converter (7) is adapted to switch between a high current generating mode (40), in which the power converter (7) is configured to draw current pulses from said power supply (2) to provide a first average input current (33a), and an OFF mode (42) in which no current is drawn from said power supply (2). In said second operating state, said power converter (7) is adapted at least to operate in a low current generating mode (41), in which the power converter (7) is configured to draw a current from said power supply (2) to provide a second average input current (33b) which is lower than said first average input current (33a).

摘要： A circuit arrangement for controlling the brightness of at least one LED unit is described by the disclosure. The circuit arrangement, in one example, includes an input for receiving a phase-cut operating voltage from a power supply, a signal processor, connected with the input and adapted to provide a dimming signal for the at least one LED unit from the operating voltage. To allow an efficient reduction of noise in the dimming signal but simultaneously to allow an improved dimming of the LED unit, the signal processor are configured to operate at least in a noise suppression mode and a dimming mode. A control device is provided, connected with the signal processor and configured to set the mode of the signal processor in dependence of the variation in the operating voltage.
