Abstract

A lighting apparatus includes a top cover, a light source and a bottom cover. The top cover has a top surface, a slope surface and an inner wall. The slope surface and an inner wall form a cavity below the top surface. The inner wall has a light opening. The light source emits a light with a first direction via the light opening of the top cover. The light is guided by the slope surface to move with a second direction to escape from the top surface of the top cover. The light source includes a LED module and a driver for generating a driving current supplied to the LED module to emit the light. The bottom cover is plugged to fix to the top cover.
