PURPOSE: An LED(Light Emitting Diode) lighting is provided to irradiate high temperate heat to the outside by separating a switching pulse transformer from a power supply device. CONSTITUTION: A vertical heatsink plate protrudes from an upper portion of a main circuit board, and a vertical heatsink plate(112) has a horizontal heatsink plate(113) thereon. The horizontal heatsink plate has a laminated pulse transformer(114), and a heatsink plate includes plural LEDs. The heatsink plate is installed at the lower portion of a power supply device(110).
