They are equipped with an integrated circuit, solar cells and light-emitting diodes (LEDs) that enable them to harness light for power and communication.

To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has ...

The "L" stands for light, "E" stands for emitting, and "D" stands for diode. A light-emitting diode is therefore a semiconductor that produces light when an electric current flows through it.

Light pollution has been a growing problem for decades, and the recent introduction of LED (light emitting diode) bulbs has increased the amount of light coming from cities by a considerable amount.

Tokyo, Japan – Scientists from Tokyo Metropolitan University have developed a new electrode material for deep-ultraviolet (DUV) light-emitting diode applications. They used a cutting-edge ...
