More Information
Summary:The utility model provides a lamp socket, which can carry out soft start protection when a normal incandescent lamp bulb is started. The utility model belongs to a household lighting electric apparatus and is suitable for lighting fittings which use incandescent lamps in a 220V or 110V power source as light sources. The utility model makes a negative temperature coefficient thermosensitive resistor connected in series to the position between a lamp bulb and a power source through a lamp socket. Therefore, the starting resistance is added, the starting electric current is reduced and the utility model can reduce the impact to lamp wires by large starting electric current. Thereby, the utility model can protect lamp wires and extend the service life of a lamp bulb. The utility model is suitable for occasions with fluctuations of power supply and voltage.
