Lamp base, lamp socket, lamp holder

A lamp socket, also known as a light socket or bulb holder, is a device used to secure and connect a light bulb to an electrical power source. It provides the necessary electrical connection for the light bulb to illuminate. Lamp sockets come in various types and designs to accommodate different types of light bulbs and to suit various purposes. Here are some key points about lamp sockets:

Types of Lamp Sockets: Lamp sockets are designed to fit specific types of light bulbs. Common types of lamp sockets include:

• Edison Screw Base (E26/E27): This is one of the most widely used socket types and is used for incandescent, CFL (compact fluorescent), and LED bulbs.
• Bayonet Mount (B22): Commonly used in many parts of the world, especially in the United Kingdom and Europe.
• GU10 and GU24: These are specialized sockets used for certain types of halogen and CFL bulbs.
• Bi-pin Bases (G4, G9, G13, etc.): Used for various types of miniature and linear fluorescent lamps.

Components: A lamp socket typically consists of several components, including:

• Shell: The outer casing of the socket that provides structural support and electrical insulation.
• Center Contact: The metal part that comes into contact with the base of the light bulb to establish an electrical connection.
• Screw or Mounting Mechanism: The part that secures the socket to the lamp fixture.
• Insulating Sleeve: Some sockets may have an insulating sleeve or cover that surrounds the center contact to prevent accidental contact.

Features: Depending on the design and purpose, lamp sockets may include additional features:

• On/Off Switch: Some sockets have a built-in switch that allows you to turn the light on or off without using a separate wall switch.
• Dimmer Functionality: Certain sockets are designed to work with dimmer switches, allowing you to adjust the brightness of the light.
• Pull Chain: Some table lamps or floor lamps have sockets with a pull chain for convenient switching.

Installation: Lamp sockets are typically attached to the lamp base or fixture using screws or other mounting mechanisms. The wires from the socket are connected to the electrical wiring within the lamp.

Safety: When installing or replacing a lamp socket, it's important to ensure that the electrical connections are secure and properly insulated to prevent electrical hazards.

Lamp sockets play a crucial role in the functionality and safety of lighting fixtures. When working with lamps or light fixtures, it's essential to follow proper installation procedures and safety guidelines. If you're unsure about working with electrical components, it's recommended to seek the assistance of a qualified electrician.
