Zusammenfassung:In one embodiment, a light-emitting device having a reflector, an emitter and an encapsulant is disclosed. The encapsulant may have a plurality of optical structures. Each of the plurality of optical structures may be configured to attenuate light transmitting towards a first direction by re-directing towards a second direction. In another embodiment, a flashlight having a roughened area with micro-optics is disclosed. Each of the micro-optics is configured to redirect light transmitting towards a direction forming an angle relative to a longitudinal axis to a point along the longitudinal axis. In yet another embodiment, a lighting-emitting device having roughened area to reduce light along a longitudinal axis is disclosed.
