The PE4601 LED Driver chip is a very simple and cost effective high voltage integrated circuit. It has an active power factor correction implemented. No external power FET and electrolythical capacitor is required. THD is in the lower single digit percent region. This street lamp is a reference design that is scalable to a certain extend. The main board has a microcontroller based phase cut off dimmer that can be used to dimm the street lamp via a remote control or any other wireless or wireline interface. The design is available from Productivity Engineering GmbH to selected customers.
