摘要

An apparatus is disclosed comprising: a light guide having an opening formed thereon; an illumination source at least partially disposed in the opening, the illumination source including a plurality of LEDs disposed on a flexible circuit that is wrapped around a base, which may be thermally conductive, the base having a central opening, and the flexible circuit including a plurality of legs, each leg including electrical wiring for independently operating a different one of the LEDs, each leg being wrapped around a bottom edge of the base, and into the central opening, to come above the illumination source and connect to a control board that is situated above the illumination source; and a heat-dissipating element disposed over the illumination source, the heat-dissipating element being thermally coupled to the base to dissipate heat generated by the LEDs that is supplied to the heat dissipating element via the base.

說明書

In some implementations, the controller 330 may be configured to receive or detect user input selecting a given preset 340, retrieve the selected preset 340 from the memory 328, and/or change the state of one or more of the LED segments 106 in the illumination source 200 based on the retrieved preset 340. For each given LED segment 106, the controller may use the preset 340 to identify one or more settings corresponding to the given segment 106 and change the state of the given segment based on the identified settings. Changing the state of the given LED segment 106 may include one or more of: turning on or off the given segment 106, changing the brightness of the given segment 106, changing the color of light that is output by the given segment 106, changing the CCT of light that is output by the given segment 106, and/or changing any other suitable characteristic of the operation of the given LED segment 106.
