Abstract
A downlight apparatus includes a light module, a host housing, and a light module, a first rotation unit and a shifting unit. The light module includes a light housing and LED modules. The light housing defines a light opening for a light of the LED modules to escape. The host housing is used for fixing to an installation platform. For example, the installation platform may be a cavity on a ceiling or a junction box placed on a ceiling. The host housing defines a host opening. The first rotation unit is used for the light module attached to and manually rotated with respect to the host housing along a first axial line. The shifting unit is used for the light module moving with respect to the host housing with a variable exposed distance from the host opening.
