Abstract: A dongle coupled between a power supplying device for supplying power and a power receiving device for receiving power includes a downstream facing port (DFP), an upstream facing port (UFP) and a controller. The controller is arranged to control deliveries of the power and messages between the power supplying device and the power receiving device. In response to a first power request message received from the power receiving device, the controller is arranged to determine whether a power type request by the power receiving device is Programmable Power Supply (PPS) according to the first power request message. When determining that the power type request by the power receiving device is PPS, the controller is arranged to start first waiting timer, and when the first waiting timer expires, the controller is arranged to send a request accept message to the power receiving device through the UFP.

Abstract: In one embodiment, an LED filament lamp for warm dimming is presented that includes a dimmable LED driver circuit; a first channel LED filament having a first forward voltage drop which emits a first white light of a first correlated color temperature; and a second channel LED filament having a second forward voltage drop and which emits a second white light of a second correlated color temperature warmer than the first correlated color temperature. In another embodiment, an LED filament for warm dimming lamps is presented that includes a light-transmissive substrate; at least one LED die and one non-light-emitting current regulator mounted thereon and connected in series; and an adhesive bead with fluorescent particles suspended therein affixed to the light-transmissive substrate, wherein illuminating the fluorescent particles with the at least one LED die causes the LED filament to emit white light of a predetermined correlated color temperature.

Abstract: In one embodiment, a filament for LED filament lamp is presented, that includes a light-transmissive substrate; at least one LED die mounted on the light-transmissive substrate; and at least one current regulator mounted on the light-transmissive substrate, wherein the current regulator is connected in series with the at least one LED. In another embodiment, an LED filament lamp is presented, that includes a dimmable LED driver circuit; a first channel LED array with at least two LED die and a first forward voltage drop; and a second channel LED array with at least one LED dies and at least one current regulator to cause a second forward voltage drop of the second channel LED array to increase as current through the second channel LED array increases, wherein the second channel LED array is connected in parallel with the first channel LED array.

Abstract: A downlight apparatus includes a light source, a rotatable support, a confining structure and a fixing unit. The light source includes one or more LED modules. The rotatable support having a rotatable surface. The rotatable surface having a partial-sphere external surface. The light source is fixed to the rotatable support. When the rotatable support is rotated, a light emitting direction of the light source is changed correspondingly. The confining structure holds the rotatable support for rotation. The confining structure has an inner surface defining a rotating space. The rotatable support is rotated within the rotating space. The fixing unit is connected to the confining structure.
