Found in all sorts of devices, the light emitting diode (LED) is basically just a tiny chip hat fits easily into an electronic circuits.
LEDs don’t have filaments and therefore don’t get hot and won’t burn out.
A high percentage of the electrical power goes directly to generate the light, cutting down considerably on electricity demands.
They require a driver (a power supply that provides a constant voltage appropriate to the LED) and at present may be more expensive than incandescent bulbs, but they are more efficient to run.
They can appear as single light sources, as in a floor recessed up light, where their cool temperature is an advantage.
However, in the form of a linear light source, LEDs are revolutionising lighting in the home.
Linear LED light is almost s thin as adhesive tae and this thinness combined with its coolness means it can be used in shaves and coves.
