Many researchers have joined the field and applied the LED to many new markets such as mobile phone screens, LED TV, and LED Lighting.
For people who currently have to burn fossil fuels to produce meager, polluting light, LED lighting is a game changer.
The LED light bulb is more than ten times the efficiency of regular incandescent lighting, so it can save the world hundreds of billions of dollars in electricity costs.
It is very satisfying to see that my dream of LED lighting has become a reality.
I hope that energy-efficient LED light bulbs will help reduce energy use and lower the cost of lighting worldwide.
