Pendant luminaire

A pendant lighting device, comprising:

• a cylindrical outer frame having a top member, a bottom member, and one or more vertical members connected between the top member and the bottom member;
• an inner frame having a geometry smaller than the outer frame, wherein the inner frame is located within the outer frame and connected to the outer frame via one or more connecting arms, wherein the length of the connecting arms determines the vertical position of the inner frame within the outer frame;
• a planar light emitter mounted to the inner frame, wherein the planar light emitter includes a thermally conductive plate and a plurality of light-emitting diodes (LEDs) mounted on a first surface of the thermally conductive plate, wherein the plurality of LEDs are located in a two-dimensional plane that is approximately parallel with the top member and the bottom member;
• a diffuser panel connected to the bottom member that is similar in size and geometry with the bottom member;
• and
• a frame covering attached to the top member and the bottom member that defines an outer side surface of the pendant lighting device.
