A shade carrier works by providing the necessary connection point that links a lampshade securely to a lamp's structure, typically the lampholder.
A shade carrier, also known as a gimbal or gimble, is used to connect a lampshade to a lamp holder. The lamp holder is the bit on the base or lamp stand that holds the lampshade and bulb in place. Essentially, it acts as a bridge, allowing the lampshade to sit correctly and safely on the lamp base or stand.
The Connection Mechanism
The working principle is straightforward. A shade carrier is usually a metal frame with a central hole or ring and several arms extending outwards.
- Mounting onto the Lamp: The central ring of the shade carrier fits onto a specific part of the lamp, most commonly:
- Directly onto the lampholder itself, often secured below the bulb socket by a retaining ring.
- Onto a rod or column that extends upwards from the lamp base, just above the lampholder.
- Supporting the Lampshade: The outer arms of the shade carrier provide support points for the wire frame of the lampshade. The lampshade's frame rests on these arms, suspending the shade in the correct position around the bulb.
This setup ensures that the weight of the lampshade is borne by the lamp's structure (the base and stand) rather than by the bulb itself, which is crucial for safety and stability.
Types and Practical Use
Shade carriers come in various sizes, typically measured by the drop (the distance from the central ring to where the shade rests) and the diameter of the central ring that fits onto the lamp.
- Common Sizes: Available in standard sizes (e.g., 4", 5", 6", 7", 8" drop) to accommodate different lampshade heights and styles.
- Fitting: The central ring size must match the part of the lamp structure it is intended to fit onto.
- Application: Widely used on table lamps and floor lamps that utilize shades with a wire frame designed to sit on a carrier.
Benefits of Using a Shade Carrier
Using a shade carrier offers several practical advantages:
- Stable Support: Provides a firm and stable platform for the lampshade, preventing it from wobbling or tipping.
- Correct Positioning: Ensures the lampshade is centered and positioned at the right height relative to the light bulb.
- Easy Shade Changes: Makes it simple to remove or swap lampshades without needing to interfere with the lamp's electrical components, as long as the replacement shade fits the carrier.
- Safety: By supporting the shade independently of the bulb, it reduces stress on the bulb and socket, contributing to safer operation.
In summary, a shade carrier is a simple yet essential component that mechanically connects and supports a lampshade on a lamp, utilizing its frame to rest on the carrier's arms while the carrier is mounted securely on the lampholder or lamp stand structure.
