Barley Twist Wooden Floor Lamps – The caps that sit on the foundation of a light bulb are equally as crucial as the bulb themselves. True, those little metal fittings may seem fairly insignificant given their size but their importance is such that they dictate which bulbs may be fitted to which lighting fittings. Without the ideal cap, the space, alleyway, stairwell or bathtub will stay in the dark.
With the selection of lights available on the market today, there are quite definite specifications to ensure the ideal bulb is fitted. For instance, both pin, or bi-pin, the cap on some lights can only be put into bi-pin light sockets, so gu10 LED bulbs cannot be placed in a light socket which isn’t designed for the gu10 cap. However, there is more than 1 kind of bi-pin cap, with the cap on g9 halogen bulbs significantly different in appearance and design, and utilized exclusively with particular kinds of light bulbs.
The main reason behind a cap is to allow electrical contact between the electrical supply and the lighting itself, without leaving wiring and electronic elements vulnerable. The metallic pins make immediate contact with the electricity source, allowing the electricity to flow through the filament, creating the necessary energy to create the light to glow and provide the necessary illumination.
The full selection of caps is extensive, but they can be divided up into three main types, namely the bayonet, the Edison screw and the bi-pin. |} Bayonet Cap This is arguably the most identifiable cap and is more often than not found on the ordinary incandescent bulbs selection for domestic lighting, although energy saving lighting also contain this cap to allow simple change over to greener home lighting.
The layout is a simple metallic cap at the base of the bulb with 2 ears, or tiny hooks, protruding from the side. Both of these pins lock into slots in the face of the socket, to hold the bulb in place. The name bayonet is derived in the thrust and twist action that’s necessary to fit them.
