PURPOSE: A lighting apparatus is provided to improve a radiation effect by using a ventilation hole and an opening which is on the side panel of a housing. CONSTITUTION: A plurality of light emitting diodes(10) are mounted in metal printed circuit boards(110,152). A plurality of reflectors(120) surrounds the light emitting diodes. The reflectors reflect the light projected from light emitting diodes. A plurality of reflectors forms a ventilation hole emitting heat generated from the light emitting diodes. A housing(130) accommodates the metal printed circuit board and reflectors. The housing comprises a plurality of openings(138) for emitting heat generated from light emitting diodes. |
