Methods and systems of emitting different light from a multiple mode light emitting device are disclosed. An exemplary embodiment has a LED portion with a plurality of first LEDs (110) and a plurality of second LEDs (112) arranged in a first ring centered about a central axis, and a rotatable portion (106) with a plurality of light conditioning elements (116) arranged in a second ring centered about the central axis. The plurality of first LEDs emit and the plurality of second LEDs emit different types of light. Each light conditioning element receives and conditions light from one of the plurality of first LEDs when the light conditioning element is in a first position. Each light conditioning element receives and conditions light from one of the plurality of second LEDs when the light conditioning element is in a second position. The light conditioning elements may be reflector cups or may be lens. |
