TROFFER-STYLE LED LIGHTING APPARATUS

摘要

The present invention relates to a troffer-style LED lighting apparatus comprising: a hexahedral upper housing (10) having an open bottom surface and a downwardly convex bent part (11) in the center of the upper surface; a lower housing (20) extending from both sides of the upper housing (10) in a downwardly sloped direction of a set angle; a pair of substrates (40), fixed on both inner sides of the bent part (11) of the upper housing (10), for inducing the light discharge direction of installed LEDs (41) to be angled with respect to the ground; fixed members (50) attached to the inner side surfaces of the upper housing (10); and a diffusion plate (60) having parts of the outer edge thereof inserted into the coupling holes (51) provided in the fixed members (50) to cover the bottom surface of the upper housing (10).
