<p>PURPOSE: An LED lamp lighting apparatus is provided to allow a user to directly turn on an LED lamp by using 220v or 110 AC voltage. CONSTITUTION: A rectifying circuit part(10) receives an AC power source. The rectifying circuit part outputs DC power. A lighting-emitting area(20) comprises a plurality of LED lamps(21) and an overcurrent protection sensor(23). The overcurrent protection sensor is connected to each LED lamp row. An current control circuit part(30) comprises a temperature sensor(31), an FET(35), and an oscillator circuit(33). The temperature sensor measures the temperature of the lighting-emitting area. The FET switches the power supply provided to the lighting-emitting area. The oscillator circuit controls the FET.</p> |
