Abstract
A lighting apparatus includes a fixing unit, a lamp body, a base housing and multiple elastic units. The fixing unit has a central hole. The lamp body includes an inner semi-sphere housing, a rotation shaft and a light source. The base housing includes an external semi-sphere housing and a rotation connector. The rotation shaft is coupled to the rotation connector for the lamp body to rotate with respect to the base housing along a first rotation axis of the rotation shaft. The multiple elastic units are attached to the base housing. The multiple elastic units are elastically attached to the central hole for the base housing to rotate with respect to the fixing unit along a second axis. There is a tilt angle between the first rotation axis and the second rotation axis.
