How LED Lights Work

In layman terms, LEDs are small little bulbs connected to an electrical circuit. However, they do not have a filament, unlike the incandescent bulbs. LED standards for Light Emitting Diode, it is currently the most energy-efficient technology. It is a rapidly developing technology whose advancement has seen it widely used in a variety of ways from lighting to device application. Quality led bulbs are more durable, lasts longer and offers better light quality than some incandescent bulbs.

With this having been said, let us go over some of the LED’s technical details;

1. Technical Definition Of a Diode
A diode is a semiconductor device with the ability to conduct electrical current. A semiconductor comes from inferior conducting materials. They are purposely made impure by adding impurities. The conductor in pure form is made of aluminum gallium arsenide (AlGaAs) where atoms bond perfectly leaving no electrons or negatively charged particles to conduct electricity. When aluminum gallium arsenide (AlGaAs) is in impure form, the additional particles change balance thus creating holes or add free electrons. These alterations make the semiconductor material more conductive.

When a semiconductor has an additional electron, it’s called N-type material as it has more negatively charged material, while a semiconductor with extra holes is called P-type material since it has extra positively charged material. Thus electrons can jump from hole to hole moving from negatively charged area to positively charged part. Therefore a diode contains N-type material bonded together with P-type material with electrodes on either end.

2. How Diodes Produce Light
The most basic units of light are called photons. When electrons move around they produce photons; electrons move around an atom in orbital mode. Electrons have many different kinds of energy levels that are created as they orbit the atoms. Each power level per atom and as electrons drop they release energy from higher orbitals levels a lower one. The released energy is what referred to as photon.

3. The Energy Saving Characteristics Of LED Lighting Systems
They use an energy efficient technology and whose future will fundamentally change the world. The LED lighting uses 75% less energy than the incandescent light. It also lasts 25 times longer than the incandescent bulb.

4. How Different Are LED-Based Lighting Systems From Standard Lightbulbs?
The light source comes from a mix of red, green, and blue which makes white light. They also emit light in a particular direction thus reducing the use of diffusers and reflectors to trap light. It also emits little heat where in comparison incandescent bulbs release 90% heat energy.

5. How LEDs can be safer
LEDs are safer as they are less prone to creating fires or burn your fingers. Moreover, they are made from epoxy material instead of glass and therefore much more resistant to damage. Also, they are easier to install, and you can connect many without overloading the wall socket.
