Light bulbs are devices that transform the electrical energy into light energy through various processes. The first bulb consists of the nineteenth century and was patented by Joseph Wilson Swam in the United Kingdom. But the first to make a commercially viable development was Thomas Alba Edison using a carbon filament and getting, on October 21, 1879, to operate a light bulb for 48 hours.
From this date on, the evolution of lighting has been dizzying, passing through different technologies until LED light bulbs have been reached. These bulbs receive the electrical energy of the network and transform it into light energy through intermediate electronic elements also called drivers.
Parts of a light bulb
All the bulbs have the same parts, being able to differentiate three main parts.
Cap: Mechanism of adjustment or fixation of the bulb to its corresponding portal. This element is responsible for making the first contact with the voltage supplied from the electrical network and transmitting it to the inside of the bulb to perform the conversion to the lighting energy. There are many types of bushing, the most known being the E27.
Heatsink: It is where the driver is hosted. This element is usually constructed of very good ceramic or aluminum materials in heat dissipation. This aspect is very important, since, if a good dissipation of heat is not carried out, the useful life of the product can be affected. P>
Diffuser: Is the part that will make the diffusion of light with more or less opening angle depending on the morphology of it. The most known is that which has the shape of a balloon, although depending on the type of cap we will see how the diffuser can undergo variations.
Respectful of the environment
LED bulbs do not use elements harmful to the environment such as lead, mercury, cadmium, etc. In addition, due to its long useful life, it can provide the final consumer with an energy and economic saving of up to 80%, depending on the type of bulb used.
