Abstract

A downlight apparatus includes a main housing, a light module, a diffusion cover and a light guide. The main housing has a surrounding wall and a base part. The light module is attached to the base part for emitting a first light and a second light. The diffusion cover is fixed to a bottom end of the surrounding wall, for converting the second light to a peripheral light on an exterior surface of the diffusion cover. The light guide has a light entrance side facing to the base part for directing the first light through the light guide to escape at a light escape side of the light guide. The light escape side of the light guide is surrounded by diffusion cover.
