1. An illumination device with adjustable illumination directions, comprising:
a substrate having a rounded groove;
a rotating element having a top and a bottom, said bottom of said rotating element having a rounded plate rotatably disposed on said rounded groove of said substrate in order to rotate said rotating element relative to said substrate;
a reflective element having two sides pivoted on said rotating element in order to swing said reflective element relative to said rotating element;
an adjustable element longitudinally displaceably disposed within said reflective element in order to be longitudinally adjustable responsive to rotative displacement relative to said reflective element; and
at least one light-emitting element disposed on said adjustable element, the light-emitting element being thereby concurrently adjustable in light-projecting angle, longitudinal position relative to said reflective element, and angular position relative to said substrate.
