Industrial indicators: LESS HEAT, MORE LIGHT

摘要

In 1840, British astronomer and chemist, Warren de la Rue, enclosed a platinum coil in a vacuum tube and passed an electric current through it, thus creating the world's first light bulb - a full 40 years before Thomas Edison was issued a patent for creating it. Now, of course, we have the LED and one company, in particular, has taken the technology to task in a vast range of products for the panel building sector.
