Patent ID: 8657464

Claim:
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, wherein the plurality of first LEDs emit a first type of light and the plurality of second LEDs emit a second type of light that is different from the first type of light, wherein the first LEDs of the plurality of first LEDs and the second LEDs of the plurality of second LEDs are alternating with each other along the first ring, wherein each first LED of the plurality of first LEDs is aligned along one of a first plurality of radial lines extending outwardly from the central axis, wherein each second LED of the plurality of second LEDs is aligned along one of a second plurality of radial lines extending outwardly from the central axis, and wherein each second radial line is displaced from an adjacent first radial line by an angular displacement of Ø°; and 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.
