Lamp Cap

A lamp cap, also known as a lamp shade holder or lampshade fitting, is a component used to secure a lampshade to a lamp base. It facilitates the attachment and stability of the shade, directing light and contributing to the lamp's overall aesthetic.

Material

Lamp caps are commonly manufactured from the following materials:

• Metal: Brass, steel, and aluminum are frequently used for their durability and ability to be formed into various shapes. Often plated with finishes like nickel, chrome, or bronze.
• Plastic: Bakelite and other heat-resistant plastics are used for more economical options, particularly in newer designs.
• Ceramic: Less common, but used in decorative or antique lamps for aesthetic purposes.

Purpose

The primary purpose of a lamp cap is to:

• Secure the Lampshade: Holds the shade firmly in place, preventing it from falling or wobbling.
• Direct Light: Works in conjunction with the shade to control the direction and diffusion of light emitted from the bulb.
• Provide Electrical Isolation: In many designs, the cap provides a degree of electrical isolation between the lampshade and the bulb, enhancing safety.
• Aesthetic Contribution: The cap's design can complement or contrast with the lampshade and base, contributing to the lamp's overall style.

Function

The function of a lamp cap relies on a mechanical connection between the cap, the lamp harp (if present), and the shade.

• Harp Connection: Many lamps use a harp – a U-shaped wire frame – to support the shade. The cap sits atop the harp, providing a stable base for the shade.
• Friction Fit: The shade's fitter (typically a spider or uno fitter) is inserted into the cap, held in place by friction.
• Screw-In Fit: Some shades have a screw-in fitter that threads directly into the cap.
• Pressure Fit: Certain designs use a pressure fit mechanism to secure the shade.

Usage Scenarios

Lamp caps are found in a wide range of lighting applications:

• Table Lamps: The most common application, securing shades on bedside lamps, desk lamps, and accent lamps.
• Floor Lamps: Used to attach shades to the vertical support structure of floor lamps.
• Pendant Lamps: Some pendant lamps utilize caps to secure decorative shades.
• Wall Sconces: Certain wall sconce designs incorporate caps for shade attachment.
• Antique Lamps: Often found in older lamps, requiring specific replacement parts due to unique designs and materials.

Common Types

• Harp Caps: Designed for use with lamp harps, featuring a central threaded post and a saddle to hold the harp.
• Spider Caps: Accept shades with a spider fitter (three or four arms that grip the cap).
• Uno Caps: Designed for shades with a uno fitter (a threaded ring that screws onto the cap).
• Threaded Caps: Feature a threaded interior for direct attachment of shades with a threaded fitter.
• Cap with Switch/Socket: Some caps integrate a light switch or socket for added functionality.
• Decorative Caps: Available in various finishes, materials, and designs to enhance the lamp's aesthetic.
