A luminaire includes a frame, an ambient light source positioned within the frame adjacent a first end of the frame, a downlight light source positioned within the frame adjacent a second end of the frame, a diffuser connected to the frame and at least partially surrounding the ambient light source, and a reflector configured to direct light emitted by the downlight light source. A first driver is in electrical communication with the ambient light source and is configured to adjust the illuminance of the ambient light source. A second driver is in electrical communication with the downlight light source and is configured to adjust the illuminance of the downlight light source. A controller is in electrical communication with and send control signals to the drivers to change the light sources between a plurality of illuminance modes, which includes a circadian effective mode and a circadian ineffective mode.

A lampshade ring assembly, a lampshade apparatus including the lampshade ring assembly and a lampshade, and a method of assembling the same. The lampshade ring assembly may include a mounting hub having a plurality of first mounting elements arranged in a spaced apart manner, an outer ring having a plurality of second mounting elements arranged in a spaced apart manner, and a plurality of connectors each having a first end with a third mounting element and a second end with a fourth mounting element. The connectors may be detachably coupled to: (1) the mounting hub via engagement between the first mounting elements and the third mounting element; and (2) the outer ring via engagement between the second mounting elements and the fourth mounting element. The outer ring may be configured to be coupled to a lampshade and the mounting hub may be configured to be coupled to a light fixture.

The present invention discloses a lamp device, which comprises a base, a lamp seat installed in the base and electrically connected with a circuit board, at least one USB interface, and a lamp shade hooding the lamp seat thereinside. The USB interface includes a cartridge disposed in the base and a USB socket module disposed inside the cartridge. The USB socket module is separated from the circuit board and electrically connected with the circuit board through cables. A wall of the cartridge has at least one opening. The interface of an external USB data line can be passed through the opening and inserted into the socket of the USB socket module. The USB interface is reduced to a smaller size and requires less space for installation. Therefore, the position for installing the USB interface has higher selectivity, and the overall esthetics of the base is improved.
