Old Reclaimed Wood Floors – The caps that sit on the foundation of a light bulb are equally as important as the bulb. True, those little metal fittings may seem rather insignificant due to their size but their importance is such that they dictate which bulbs can be fitted to which light fittings. Without the ideal cap, the room, alleyway, stairwell or backyard will remain in the dark.
With the range of lights available on the market today, there are very definite specifications to make sure that the ideal bulb is fitted. For instance, the two pin, or bi-pin, the cap on certain lights can only be placed into bi-pin light sockets, therefore gu10 LED bulbs can’t be set in a light socket that isn’t meant for the gu10 cap. However, there’s more than 1 type of bi-pin cap, together with the cap on g9 halogen bulbs significantly different in appearance and design, and utilized only with certain types of halogen bulbs.
The main reason behind a cap would be to permit electrical contact between the electric supply and the light itself, without leaving wiring and electronic elements vulnerable. The metallic pins make immediate contact with the power source, allowing the power to flow through the filament, creating the necessary power to create the light to glow and provide the necessary illumination.
The entire range of caps is extensive, but they are sometimes broken down into three principal kinds, namely the bayonet, the Edison screw and the bi-pin. |} Bayonet Cap This is potentially the most recognizable cap and is more often than not found on the ordinary incandescent bulb selection for national lights, though energy saving lights also contain this cap to permit simple switch over to greener home lighting.
The design is a simple vertical cap at the bottom of the bulb with two ears, or tiny hooks, protruding from the side. Both of these pins lock at the side of the socket, to hold the bulb in place. The title bayonet comes from the thrust and twist action that’s needed to match them.
