LED lemputės viską, ką reikia žinoti: skirtingi tipai ir dangteliai, įrenginiai, charakteristikos.

General features Light bulbs are devices that transform electrical energy into light energy through various processes. The first light bulb appeared in the XIX century and was patented by Joseph Wilson Swam in the United Kingdom. But the first to realize a commercially viable development was Thomas Alba Edison using carbon filament and on the 21st of October of 1879, managed to get a light bulb to function for 48 hours. From this date on, the evolution of lighting has been dizzying, passing through different technologies until it reached LED light bulbs. These light bulbs receive electrical energy from the grid and transform it into light energy through intermediary electronic elements as well as so-called drivers. Parts of a light bulb All light bulbs contain the same parts, which can be broken down into three main parts. Socket: Adjusting or fixation mechanism of the light bulb to its corresponding lamp holder. This element is in charge of making the first contact with the voltage supplied by the electricity grid and will transmit it towards the interior of the light bulb for the conversion to light energy. Many types of sockets exist; the best known remains the E27. Heat sink: This is where the driver will be housed. This element is usually made of ceramic or aluminium materials that are very good at dissipating heat. This aspect is very important, because if there is no proper heat dissipation, the lifespan of the product can be affected. Diffusor: This is the part that will diffuse light with a greater or smaller angle of aperture. The best known is the one that has a spherical shape, whereas the diffusor can come in variations according to the type of socket. Environment-friendly LED light bulbs do not use elements that are harmful to the environment, such as lead, mercury, cadmium, etc. Furthermore, due to its long lifespan, it saves energy and money for the end consumer of up to 80%, according to the type of light bulb used.
