Abstract: A range-extended numerical controlled link mechanism electric loader comprising a vehicle-loaded rechargeable energy storage device, a vehicle-loaded auxiliary power supply device, a motor, a reducer, a numerical controlled link lever loading mechanism and a rack. The vehicle-loaded rechargeable energy storage device comprises at least a battery, an electric control module, and at least one charging port; the vehicle-loaded auxiliary power supply device comprises an engine and a generator; by cooperation of the vehicle-loaded rechargeable energy storage device and the vehicle-loaded auxiliary power supply device the loader can have five different working modes: low speed mode, high speed mode, hybrid low speed mode, hybrid high speed mode and energy recycling mode, by the different working modes, the wheels can be driven to rotate or the drive levers can be driven to conduct loading work.

Abstract: In order to provide a balance between a fast start-up in start-up phase and a low light output ripple in normal operation phase, it is provided a LED driving circuit comprising: an input to receive a LED driving current, a buffer circuit adapted to buffer said LED driving current, and an output to be connected to LED and adapted to output the LED driving current, after buffered, to the LED, characterized in that, further comprises a buffer adjustment circuit adapted to adjust the buffer capability of the buffer circuit at a first level, in a start-up phase of the LED driving circuit when the LED driving circuit starts to receive said LED driving current, and adjust the buffer capability of the buffer circuit at a second level larger than the first level in a normal operation phase later than the start-up phase.
