Fan Blade LED Lamp Repair at Home || Tech Sajju

A LED light bulb is a modern and efficient light source. LED bulbs are safe – they do not contain mercury or other toxic elements and do not cause harm when they are broken. However, the first thing that encourages us to buy these bulbs is their cost efficiency due to low electricity consumption. What’s more, LED devices are rather reliable and usually serve all their lifetime. Thus, the advantages of this light source are evident: it’s bright and serves long. Traditional incandescent light bulbs cannot be repaired at all, while in LED bulbs you can repair almost everything. You just need to find the malfunction, make some repair and prolong your light bulb lifetime. If you are familiar with repair operations you can even find all necessary tools at home; all you need is to find some time for that. LED bulb LED bulb operation is based on the abilities of some materials to emit light under certain conditions. The working element of the bulb, a light emitting diode is a semiconductor device that emits incoherent light when electric current runs through it. LEDs emit light only if you use DC current. To put it simply, a LED transforms the electric current into light emission. This light source consists of a semiconductor crystal on a non-conductive base, a housing with contacts and an optical system. To increase LED stability the space between the crystal and the plastic lens is filled with transparent silicon. Aluminum base reduces overheating. Under normal conditions heat...
