Abstract

A downlight apparatus has a main cup housing, a driver circuit, a first LED set, a second LED set and a light guide cup. The driver circuit is contained in the main cup housing for converting an external power to a driving current. The first LED generates a central luminous effect. The light guide cup has a top part and a bottom part. A light output pattern is formed on internal surface of the light guide cup between the top part and the bottom part. The top part receives a light of the second LED set. The light enters the light guide cup and escapes from the light output pattern.
