A lamp shade typically attaches to a lamp by sitting on a part of the lamp base or harp, or directly on the lamp socket assembly, often secured by a finial or the light bulb itself.
Attaching a Lamp Shade: The Socket-Ring Method
One common way a lamp shade goes on a lamp is using a socket-ring fitting, often found on smaller lamps or desk lamps. This method directly utilizes the lamp's light bulb socket to hold the shade in place.
Here's how it works:
- Prepare the Lamp: Ensure the lamp is unplugged for safety.
- Position the Shade: The lamp shade has a ring (or "fitter") at the top opening designed to rest on the lamp socket. Place the shade over the socket so the ring sits snugly.
- Secure with the Bulb: As stated in the reference, you screw a light bulb into the socket to secure the shade to the lamp. The base of the light bulb pushes down on the shade's ring fitter, pressing it against the socket and holding the shade firmly in position.
This method ensures the shade is stable and aligned with the lamp base. Once the bulb is tightened sufficiently to hold the shade without wobbling, the lamp is ready for use.
This type of fitting is sometimes referred to as an "Uno" fitter, particularly when the ring is permanently attached to the shade frame and screws directly onto threads below the socket. However, the general principle of the shade resting on the socket and being secured by the bulb is common to several designs.
By following these steps, your lamp shade will be correctly assembled and secured.
