There are many types of light bulbs that can be found throughout the world. New technologies and innovations have seen the inclusion LEDs (more info below) into the standard light bulb which has significantly refined the process of emitting light. Whilst the bulb structure has not changed too much, the technology inside a bulb has advanced dramatically. This is how the original Edison filament light bulb works. This current is met with a high resistance whilst passing through the filament and the energy forces it’s way through this filament, creating heat and then produces light. When the bulb is inserted into a lamp or socket, contact is made with the main electrical circuit to create an electric current. Typically, the bulb is filled with a non-reactive gas to aid with light quality and make a more durable bulb. Filaments are coiled wires that are held up by glass mounts in the centre of the bulb. The contacts are attached to two wires which are connected to a very thin metal filament. The base of a bulb consists of two metal contacts which connect to the ends of an electrical circuit.
The structure of a light bulb hasn’t changed much since it was first invented.
Once you’ve read through this guide, visit our Light Bulbs category to peruse our selection of lighting options! The working method and technology used in light bulbs has been refined over the years with the inclusion of LEDs and a plethora of modern technologies. The simplest definition of the original light bulb is a glass bulb that is inserted into a lamp or a socket that provides illumination.
