Title:
POWER SUPPLY APPARATUS FOR LED LIGHTING
Document Type and Number:
WIPO Patent Application WO/2015/080462
Kind Code:
A1
Abstract:
The present invention relates to a power supply apparatus for an LED lighting, comprising: a printed circuit board on which a circuit for converting input power into output power for driving the LED lighting is printed; an MCU, which comprises a driving voltage port, a ground port, and a voltage sensing port and is connected to the printed circuit board, for delivering control signals to the circuit so that a current applied to the LED lighting is converted based on a voltage inputted into the voltage sensing port; a first resistance of which one end is connected to the driving voltage port and the other end is connected to a voltage sensing node; a second resistance of which one end is connected to the ground port and the other end is connected to the voltage sensing node; a sensing wire of which one end is connected to the voltage sensing port and the other end is connected to the voltage sensing node; a first wire of which one end is connected to one end of the first resistance and the other end is open; a second wire of which one end is connected to one end of the second resistance is the other end is open; a third wire including a third resistance wherein one end of the third resistance is connected to the voltage sensing node and the other end of the third resistance is open; and a housing provided with an inner space to which the printed circuit board, the MCU, the first resistance, the second resistance, the sensing wire, and one end of the first to third wires are coupled.
