Lighting apparatus using led

PURPOSE: A light emitting diode(LED) illuminating apparatus is provided to form an optimal illuminating region by arranging a plurality of rotatable reflecting plates on a main body. CONSTITUTION: An LED illuminating apparatus includes an LED substrate(100), a main body(200), and a plurality of reflecting plates(300). A plurality of LED elements is mounted on the LED substrate. The LED substrate is arranged in the polygonal opening of the main body. The plurality of reflecting plates is arranged on the long side of the main body. A reflecting plate includes a reflecting panel part(310) and a hinge bonding part(320). The reflecting panel part reflects light from the LED elements. The hinge bonding part is hinge-bonded with the short side of the main body.
