A lighting device comprises a light emitter (100) with a spherical translucent body (101) containing at least one reflector (102) and defining large, combined incident (109) and emission (105) lenses.The light emitter reflects and focuses light from a waveguide (40) to project a beam onto a target surface. The light emitter is preferably slidably mounted for rotation on a support element (20) which may comprise a circular aperture (22) in a plate, and may be configured as a desk or stage lamp, a wall light, or a downlighter suspended beneath a ceiling. The waveguide or light emitter may provide ambient or uplighting in addition to the beam. 种照明设备，包括具有球形半透明体(101)的光发射器(100)，该球形半透明体包含至少个反射器(102)并限定大的组合的入射透镜(109)和发射透镜(105)。光发射器反射并聚焦来自波导(40)的光，以将光束投射到目标表面上。光发射器优选可滑动地安装成在支撑元件(20)上进行旋转，该支撑元件(20)可以包括板中的圆孔(22)，并且该光发射器可以被配置为台灯或舞台灯、壁灯或悬挂在天花板下面的下照灯。除了光束之外，波导或光发射器可以提供环境照明或向上照明。
