A brief video showing how LED lights work. LED lights work using one of the simplest light emitting diodes. This diode is silicone based. It has both a positive material and negative material sandwiched beside each other, when they are combined they create a p-n junction. This p-n junction is the area in which the light is created. The lens of the LED then refracts this light into a spherical illumination. led lights/lamps can usually be powered by 12v and are used in the auto and automotive industry. LED lights are expected to improve efficiency and light output significantly over the following number of years, they should eventually totally replace the incandescent light bulb.
Even though LED's are everywhere, there's still the question - how do LED's actually work?
Like... deep down on a molecular level? Well, we go over how these amazing LEDs work by discussing how the electrons lose energy, emit photons, and how scientists and engineers get specific colors. We also go over the way the semiconductor material is packaged into something that we can use.
CircuitBread is joining the fight to help people more easily learn about and use electronics. With an ever-growing array of equations, tools, and tutorials, we're striving for the best ways to make electronics and electrical engineering topics more accessible to everyone.
LEDs are becoming really common so let’s see how an LED works, makes different colors and have become TVs. In this video, I talk about the origins of the LED, how it started as an infra-red LED, then came the RED LED, followed by the yellow and blue. LEDs are types of diodes, produced as semiconductors. LEDs are about 50 years old, the first one being invented in 1961.
LED lights are becoming more and more popular as they require less energy. As you can tell from the name Light emmitting diode - LEDs are in fact a type of diode
LEDs operate only in the forward bias where the p-type is connected to positive and n-type connected to negative. The electron-hole flow is what allows light to be produced. This to do with the position of the electron within energy levels. Dropping energy levels, electrons lose energy and this energy is given off as photons are particles of light. These particles of light are what we see.
Different types of materials are used to create different colours of LEDs. As the colour of the LED increases, of course the frequency of light also increases as well as the voltage drop across the LED.
LEDs can be really useful as they can be used for lighting (LED strip lights), control (infra red), making LED tv and various uses. Recently, LEDs have moved over to the communications field as light emitted from the LED can be encoded to carry data. Researchers have achieved data speeds of up to 10Gbits/second. That is crazy! Hopefully we will see more of LED communication in the next few years.
