摘要： A radiation emitting device for emitting light may include a laser light source configured to emit light along an emitting direction, and a non-imaging optical system arranged downstream of the laser light source in the emitting direction. The optical system may include a plurality of optical elements arranged along the emitting direction for shaping a radiation characteristic of the radiation emitting device in a horizontal direction and a vertical direction perpendicular to the horizontal direction, such that the radiation characteristic is asymmetrical along the vertical direction. A first optical element of the optical system may be configured to cause spreading of the light along the horizontal direction; a second optical element of the optical system may be configured to cause collimation of the light along the vertical direction, and a third optical element of the optical system may be configured to cause radiation asymmetry along the vertical direction.

摘要： A radiation emitting device may have a plurality of emitters and a plurality of optical elements. The emitters may be arranged along a first emitter direction at a first average emitter spacing AE1 and along a second emitter direction extending obliquely or perpendicularly to the first emitter direction at a second average emitter spacing AE2. The optical elements may be arranged along a first optics direction at a first average optics spacing AO1 and along a second optics direction extending obliquely or perpendicularly to the first optics direction at a second average optics spacing AO2.
