Socket/Base/Holder
01
Screw socket lamp holder, metal thread
Structure and Principle
- The screw-type lamp holder comprises a metal threaded part and a central conductive contact. When the bulb's lamp head is screwed into the socket, the threads interlock for mechanical fixation. Simultaneously, current flows from the socket through the holder to the bulb, making it light up. Wire gauze is used in labs and unrelated here.
Characteristics
- It has a relatively stable connection. During use, it resists loosening from minor vibrations or impacts, ensuring a steady link between bulb and socket, minimizing flickering or outage due to poor contact. Its installation and removal are easy, needing no extra tools. A flat cord can power such lamps.
Application Scenarios at Home
- In every room of the living room/sitting room, like chandeliers, ceiling lights, wall lights, and table lamps often use screw-type holders. This lets users pick and swap bulbs as needed.
Industrial Application
- In factories and warehouses, some lighting fixtures adopt screw-type holders too. Thanks to their stability and reliability, they meet the demands of harsh environments. Fuses protect circuits, and a ceiling fan might share the space. An IKEA floor lamp could use similar tech.
