Reuters, 50 years ago when his inventions show the GE executives, LED (light emitting diode)尼克奥隆尼inventor Senanayake (NickHolonyak) was convinced LED will replace incandescent bulbs. Although incandescent bulbs are still the mainstream in home lighting, LEDs have changed lighting applications in many ways. From the switch light that emits a faint red light to the high-brightness street lights used in the streets of major cities, LEDs have been accepted around the world. Ubiquitous red LED The first LED light is red. This is not for aesthetic reasons. LEDs are made by creating a multilayer semiconductor wafer on a silicon wafer. As more and more semiconductor wafer layers are added, people are beginning to use various additives to determine the color of the LED lights. The fine silicon wafer is immersed in the molten liquid, followed by the addition of metal contacts and wires. The phosphorous gallium arsenide solution used in the first LED lamp produces a natural red light from the LED lamp. Therefore, the default color of the LED light used as the indicator light is red. LED lights made with the new technology can also emit light of other colors, which greatly expands the application range of LED lights. But in the first 10 years after the advent of LED lights, the light from this lamp has been red.
