There are inventions that make life more convenient, and there are inventions that truly change the world. LED lighting in San Jose is a much more efficient and sustainable lighting method, and it can be life-changing for people who aren’t connected to the electric grid. Watch this video on how 3 scientists began changing the world with LED lights.
LED stands for light-emitting diode, and this type of lighting seeks to replace incandescent and fluorescent bulbs by the year 2050. Green and red LEDs were discovered first, and once their blue counterpart was developed, we could combine the 3 of them for practical, white lighting. For people in third-world countries who don’t have access to the electric grid, the efficiency that LEDs offer is crucial. Even without access to the grid, people could use LEDs to light their homes rather than burn wood or gas.
