Abstract: An LED driver is based on a linear driver for driving a controlled current from the mains input voltage whose rated value is fixed. The current flows in a time period during which the amplitude of the mains input voltage exceeds a forward voltage of the LED arrangement, and this time period has a low frequency variable duration, due to a variation of the input mains voltage at the low frequency, or due to a variation of the forward voltage of the LEDs. In one aspect the control circuit further controls the number of series LEDs driven by said drive circuit arrangement in dependence on the RMS value of the input mains voltage which varies at said low frequency, to provide a better efficiency, and the control circuit also adjusts the current in dependence on the variable duration and the LED forward voltage such that the average energy flow is controlled.

Abstract: An AC/DC converter and conversion method are provided, in which an AC input is rectified and shaped by a waveform shaping capacitor. A current source circuit is used to provide the output current to the output load which has a parallel bulk capacitor. The current source circuit is switched on and off with timing which is dependent on the phase of the AC input signal. This enables a relatively high power factor, for example between 0.7 and 0.9, with low cost circuitry with few components.

Abstract: A tubular lighting device comprises a tubular housing (12) having an elongate axis and first and second opposite ends, each end comprising two projecting electrical connection pins (16). A switch arrangement (60) is used to electrically isolate the projecting electrical connection pins of one end from the electrical connection pins of the other end. This provides a safety feature when fitting the lighting device to a luminaire. The tubular housing comprises a recess (20) in which an actuator surface (50) is provided for actuating the switch arrangement such that the actuator surface is internal of the outer envelope of the tubular housing. The actuator surface is for actuation by a key (42) inserted into the recess. A key is thus inserted to activate the lighting device. This reduces the risk of accidental activation.

Abstract: A level control circuit uses a reference voltage generated from a mains voltage signal by a reference circuit to provide a feedforward control signal. This control signal is used to generate a control signal for controlling a switched mode power converter. The reference circuit comprises a combining circuit adapted to apply a pulse width modulation control signal indicative of said level such that said reference voltage contains the level information. In an embodiment, the reference circuit comprises a voltage divider comprising a resistor circuit and the combining circuit comprises an adjustment module to which a pulse width modulation control signal is applied thereby to change the effective voltage divider ratio to implement level control. The level control further comprises a buffering capacitor or a buffered low pass filter coupled to the output (SET) of the voltage divider. This provides a power factor correction approach for active level control, and which can be implemented very simply and with low cost. It can be used for controlling lighting dimming.
