Padding Under Wood Floor – The caps that sit on the foundation of a light bulb are just as important as the bulb themselves. True, those little metal fittings might appear fairly insignificant due to their size but their importance is such that they dictate which bulbs can be fitted to which lighting fittings. Without the ideal cap, the space, alleyway, stairwell or backyard will stay in the dark.
With the range of lights available on the market today, there are very definite specifications to ensure that the ideal bulb is fitted. For instance, both pin, or bi-pin, the cap on certain lights can only be put in bi-pin light sockets, so gu10 LED bulbs can’t be placed in a light socket which isn’t designed for the gu10 cap. But, there’s more than 1 kind of bi-pin cap, with the cap on g9 halogen bulbs considerably different in appearance and design, and used exclusively with certain types of light bulbs.
The main reason behind a cap would be to permit electrical contact between the electric supply and the lighting itself, without even leaving wiring and electronic elements vulnerable. The metallic pins make immediate contact with the electricity supply, allowing the electricity to flow through the filament, producing the essential power to cause the light to glow and supply the necessary illumination.
The entire range of caps is extensive, but they can be divided up into three principal types, namely the bayonet, the Edison screw and the bi-pin. |} Bayonet Cap That is arguably the most identifiable cap and can be more often than not found on the ordinary incandescent bulbs selection for national lighting, although energy saving lighting also feature this cap to permit easy switch over to greener home lighting.
The design is a simple metallic cap at the base of the bulb with two ears, or small pins, protruding from the side. Both of these pins lock into slots at the side of the socket, to hold the bulb in place. The title bayonet comes in the thrust and twist action that’s necessary to fit them.
