Digital light

The Led is primarily a diode , which can be easily integrated on a printed circuit, and easily manageable ,  which result in moving the production of light from physics to the digital age (conventional light emission is done with excitation of a particle like gas mercury, sodium , ... or tungsten heating, ...) . The arrival of the digital light revolutionises the use of light and the space that it will occupy in our lives by opening the field of possibilities. The revolution taking place is similar to what happened in photography, when films changed from silver to digital . Just as the invention of the Lumière brothers no longer serves to capture the present moment, the work of Becquerel, Edison and Claude are no longer any use to see , to be seen and to live .
