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
