Abstract:
1. A multiple mode light emitting device, comprising: a light emitting diode (LED) portion comprising a plurality of first LEDs and a plurality of second LEDs arranged in a first ring centered about a central axis, a rotatable portion including a plurality of light conditioning elements arranged in a second ring centered about the central axis, wherein the second ring and the first ring have the same diameter, wherein the rotatable portion is configured to rotate between a first position and a second position, wherein rotation of the rotatable portion between the first and second positions rotates the plurality of light conditioning elements relative to the plurality of first LEDs and the plurality of second LEDs, wherein each light conditioning element receives and conditions light from one first LED of the plurality of first LEDs when the rotatable portion is in the first position, and wherein each light conditioning element receives and conditions light from one second LED of the plurality of second LEDs when the rotatable portion is in the second position, wherein the rotatable portion is rotated about the central axis by the angular displacement of Ø° to move between the first position and the second position.
