Lighting technologies

By taming fire 400 000 years ago, man was equipped for the first time with a means allowing him at once to have fire heating and to use fire lighting.

Since, tremendous technical progress was made, including lighting, from the first electric incandescence bulbs invented by Edison until the last decades development: the Light-Emitting Diodes (LED).

The development of lighting systems requires to study the problems of conversion of the electrical energy consumed in bright energy, by minimizing the heat production. Besides, the life expectancy of light source must be also optimized.

We suggest you to discover more details concerning the following three technologies of lighting:
The main technologies are below :
