Fire, light and tools are the most important discoveries in the history of humankind.
Light opened up a world for the homo sapiens that had been almost totally closed to them before: the world of night. Due to the microelectronic revolution, the world of light is on the move. Light sources based on semiconductor technology are gaining ground. Edison’s lamps will soon be exhibits in museums of industrial history. LEDs (Light Emitting Diodes) save energy and reduce CO2 emissions – a benefit to our overheated planet.
