LED LIGHTING APPARATUS

摘要

PURPOSE: An LED device is provided to improve optical power by discharging heat using a heat sink and a heat radiation unit. CONSTITUTION: A cover unit includes a first cover(109), a cover ring(111), and a second cover(113) and receives a first substrate(107) and a second substrate(115). A heat sink(101) discharges heat from the inside of the cover unit to the outside. A heat radiation unit(130) is combined with one side of a second cover and discharges heat. The LED device of the first substrate and the LED device of the second substrate emit light in different directions.
