Abstract: This application relates to the field of lighting, and discloses an LED filament. The LED filament includes an LED chip unit, a light conversion layer, and an electrode. The light conversion layer covers the LED chip unit and part of the electrode, and a color of a light emitted by the LED filament after lighting is different from a color of the light conversion layer. This application has the characteristics of uniform light emission and good heat dissipation effect.

Abstract: A flap support mechanism includes a carrier beam on which a flap is mounted. The carrier beam is rotatably mounted to a flap support for rotation relative to a wing. A crankshaft assembly is rotatable about an axis and has a crankshaft eccentrically extending between an inboard cylindrical support and an outboard cylindrical support. A coupler link is rotatably engaged to the crankshaft and pivotally connected to the carrier beam. Rotation of the crankshaft from a first eccentric position to a second eccentric position translates the coupler link between a retracted position and a deployed position.

Abstract: An actuation mechanism, a flap mechanism, and an aircraft. The actuation mechanism includes drive links and drive mechanisms connected to opposite ends of the flap that move the flap to various positions. The drive mechanisms are actuated by torque tubes connected to a drive motor via a differential. The differential distributes torque to the torque tubes. In the event of abnormal operation of one of the drive links or drive mechanisms, the differential limits torque to the remaining drive link and drive mechanism such that the flap does not deploy or retract in a skewed manner.

Abstract: A deployable vortex generator attached to a lifting surface includes a vane moveable relative to the lifting surface. The vane moves from a deployed position to a retracted position in response to a change in ambient conditions. In the deployed position, the vane acts on the air flow to create vortices. In the retracted position, the vane is closely aligned with the free stream velocity.

Abstract: An apparatus for ground fault current interrupter with overall end-of-life indication and shutdown protection function includes a first silicon-controlled rectifier, a reverse unit, a test switch unit and a ground fault current interrupter. The ground fault current interrupter includes a second silicon-controlled rectifier, a switch unit, a switch control unit and a rectifier filter unit. When a test current leakage signal is generated, a drive power is provided to the reverse unit, and the input power supply generates a current leakage phenomenon. If the ground fault current interrupter fails, then the second silicon-controlled rectifier will not be triggered, which makes the reverse unit trigger the first silicon-controlled rectifier, such that the rectifier filter unit outputs a DC power flowing through the first silicon-controlled rectifier to interrupt a power supply of the switch control unit.
