A LIGHT SOURCE APPARATUS FOR LED ILLUMINATION AND BLU

摘要

PURPOSE: An LED lamp and a backlight unit lighting apparatus are provided to improve lighting efficiency while minimizing various failure factors by the heat from an LED. CONSTITUTION: A plurality of LEDs(10) emits light by receiving an external power source. A patterned substrate(20) comprises a substrate(21) and a conductive pattern(22). The conductive pattern is electrically connected to a plurality of LEDs. A heat sink(30) comprises a plurality of heat radiation fins(31). An opening part is formed in one side of a housing for emitting the light.
