  • Publication number: 20230287897
    Abstract: An electric ceiling fan and ceiling fan kit having adjustable fan blades. The fan and kit include blade irons each with an arm having various mounting holes drilled at different distances from the hub. When the fan blades are attached to specific holes on the blade iron, the sweep of the fan blades is adjusted and set. Different length fan blades and/or blade irons may be used to adjust the fan blade sweep diameter. The blade iron may be constructed from sections that are stackable or removable, again to adjust its length by the installer and thus increasing or decreasing the fan blade sweep diameter. The blade iron may telescope to set its length, and the twist lock threads also allow for setting a blade pitch angle. The blade iron may twisted along its length to deform its shape or be inserted at an angle into the motor hub to set the blade pitch angle.

  • Publication number: 20150009666
    Abstract: A universal LED light kit adapted to retrofit or modify a standard ceiling fan having a switch cup, or a ceiling light fixture attached to an electrical outlet box. A LED board having a plurality of spaced apart LEDs is mounted to the exterior of the housing, wherein a LED driver disposed inside the housing powers the LED board. An upper threaded nipple, extension tube, and/or fasteners disposed at the top of the housing connect the kit to the outlet box or the switch cup. A lower threaded, hollow nipple disposed at the bottom of the housing receives a nut or finial to hold the assembly together; attaches a bowl shaped diffuser to the kit; and facilitates a chain pull to pass through to control the fan or light fixture. Electrical wiring passes through the upper nipple and connects the LED driver to the outlet box or the switch cup.
