Abstract: An illumination panel device includes a housing, a first circuit board, a second circuit board, and a light guide. The housing includes a frame coupled to a rear cover. The frame defines an opening. The first circuit board includes a plurality of white light emitters. The first circuit board is coupled to the frame such that the plurality of white light emitters are arranged around the opening. The second circuit board includes a plurality of multi-color light emitters. The second circuit board is coupled to the frame such that the plurality of multi-color light emitters are arranged around the opening. The light guide has opposite front and back surfaces. The light guide is arranged in the opening with the back surface facing the rear cover. The light guide is optically coupled to at least the plurality of white light emitters through peripheral edges of the light guide.

Abstract: A lamp including a light emitting module having a base substrate with a mounting surface, a plurality of white-light emitting elements disposed on the mounting surface in a circular arrangement with a central axis extending from a center thereof, an elongated support structure extending longitudinally along the central axis from the mounting surface, and at least one row of red-green-blue-light emitting elements distributed along the elongated support structure lengthwise. The lamp further including a light diffuser cover placed over the plurality of white-light emitting elements with the elongated support structure inserted therethrough, and a hollow lamp shade fitted over the light emitting module to surround the elongated support structure with a base opening of the hollow lamp shade interfacing the base substrate, wherein a rim of the base opening encircle the plurality of white-light emitting elements capable of illuminating the hollow lamp shade from the base opening.

Abstract: In an embodiment, a method includes: patterning a lower semiconductor nanostructure, an upper semiconductor nanostructure, and a dummy nanostructure, the dummy nanostructure disposed between the lower semiconductor nanostructure and the upper semiconductor nanostructure, the dummy nanostructure including doped silicon; forming an opening between the lower semiconductor nanostructure and the upper semiconductor nanostructure by etching the doped silicon of the dummy nanostructure; forming an isolation structure in the opening; and depositing a gate dielectric around the isolation structure, the upper semiconductor nanostructure, and the lower semiconductor nanostructure.
