More than a century has passed since Edison invented the world\'s first electric light bulb in 1879. Compared with candlelight, the electric light bulb is indeed a major improvement, but it has not been improved much. Its principle is almost the same as that of a candle, which emits light by heating, so 90% of the energy is consumed in heating, and the life span is generally only about 1,000 hours.
