Conceptual Designs Bulb Redesigns Ballast Redesigns Rotation Designs Alignment Designs Extension/Retraction Design

Bulb Redesign: Extended Prong Bulb Extend the metal part on either end of the bulb (+) Allows for a more durable place to grip the bulb (+) Uses standard light bulbs

Bulb Redesign: Double D Bulb Extending the metal out on either end (+) Flat sides on metal ends allowing for easier way to grip and rotate (+) Uses standard light bulbs

Bulb Redesign: Hex Bulb Extending the metal on either end (+) Metal ends in hex shape for easier way to grip and rotate (+) Uses standard light bulbs

Ballast Redesign: Wide Channel Ballast (+) Uses standard light bulbs Utilizes channels to align the bulb and automatically rotate it into place

Ballast Redesign: V Clamp Ballast (+) Uses standard light bulbs Held in place by two pieces of metal forming a “V” Extension rod separates the “V” for installation/removal

Ballast Redesign: L – Hook Ballast (+) Uses standard light bulbs (+) Bulb is installed and removed without rotational movement Bulb pins rest in L- hook contact area

Bulb/Ballast Redesign: Clip Ballast (+) Easy removal and installation Clipping Ballast connection

Rotation Design: Gear and Pinion Rotator (+) Uses standard light bulbs and ballasts Rotate bulb to correct position once placed in a ballast (-) Complex mechanism Enclosure required for safety

Rotation Design: Rubber Wheel Bulb Rotator (+) Uses standard light bulbs and ballasts Bulb pins aligned vertically Bulb placed in rubber or plastic flexible fingers protruding from the U-channel Bulb sits on a row of rubber wheels (with high coefficient of friction) The rubber wheels are connected by a solid horizontal shaft and this shaft if geared to a vertical shaft by a bevel gear The vertical shaft connects to the handle at the bottom of the device Once the bulb is in place and aligned, the handle is turned by the user, which rotates the rubber wheels, thereby rotating the bulb into place (+) Device is then pulled away from (unsnapped) from bulb as flexible fingers will move to the side For removal, device is “snapped” onto bulb and handle is turned, then bulb is brought down

Alignment Design: Cone Alignment (+) Uses standard light bulbs and ballasts Cone indention created on the light fixture assembly (+) Assures correct alignment between bulb and ballast

Extension/Retraction Design: Screw Tightening Pole Telescoping rod Screw used to secure rod in place once desired length is achieved

Extension/Retraction Design: Spring Loaded Pole Telescoping rod Rods interconnect with one another Metal spring loaded balls located on the inner rod Corresponding holes are located on outer rod User friendly
