portalampada

A portalampada, also known as a lamp holder or socket, is a device that allows an electric lamp to be connected to a power source. It typically consists of a threaded or bayonet-style socket that receives the base of the lamp and electrical contacts that make a connection with the lamp's terminals. These contacts are then wired to the main electrical supply, enabling current to flow and illuminate the bulb.

Portalampadas come in various forms and sizes, designed to accommodate different types of light bulbs, such as incandescent, halogen, fluorescent, and LED lamps. The design also varies based on the intended application, including household lighting, industrial fixtures, and specialized equipment. Common materials used in their construction include ceramic, plastic, and metal, chosen for their electrical insulation properties, heat resistance, and durability.

The primary function of a portalampada is to provide a secure and electrically sound connection for a light bulb, ensuring safe operation. It also often serves as a mounting point for the lamp itself, integrating with light fixtures and luminaires. Standards organizations set guidelines for the design and manufacturing of portalampadas to ensure safety and compatibility across different regions and electrical systems.
