Get familiar with LED Working Principle and Its Various Applications

Light Emitting Diode is a special kind of technology that allows current to flow forward and blocks its flow in the reverse direction. LEDs working principle is based on Quantum Theory. It means when electrons from high energy levels come down to low energy levels, there emits energy between the gaps of energy levels called photon energy.

Advantages of LEDs

  • LEDs are compact and can be installed even in awkward positions.
  • You can control electricity usage using dimmer or motion sensors.
  • Uses 75% less energy than incandescent lighting
  • Lasts longer than any other form of lighting solution
  • Emits less heat than CFL and incandescent bulbs
  • Safer option as they are cooler reducing the risk of burnt fingers or combustion.
  • LEDs are designed from epoxy lenses and not glass, so unbreakable.

As LEDs are highly efficient and directional they are perfect for industrial and residential uses. You can find them commonly in –

  • Street lights
  • Walkway lighting
  • Parking lots
  • Refrigerated case lighting
  • Task lighting
  • Modular lighting
  • Recessed downlighting in kitchen

Various applications of LED Lighting

If you try to reflect on some years back, you’ll find that LED lighting was commonly used for Christmas lights and laser beams. However, with the rapidly growing technology LED lighting has evolved from the traditional use to a million sophisticated applications. LED lighting is the leading brand today. It has surpassed the traditional lighting solutions in terms of efficiency and cost-effectiveness. Below are various applications of LEDs:

Virtual Sky

Sometimes home and working environments can become so monotonous and boring, but a little touch by way of lighting design can make all the difference. LED technology has taken care of this monotony by developing a LED virtual sky. This is a panel that replaces the boring ceiling into an environment that looks sky like. This ideally was to make an environment look more outdoor with a blue sky and moving cloud. This not only makes the working environment look attractive but also increases productivity.

Car Sunroof

A car sunroof is a panel that is put on the roof of the car to allow light, air, or both to enter into the vehicle. If you’ve ever driven under the scoring sun, then you can attest to the frustrating experience. LED car sunroofs take care of all these frustrations. The solar-powered led makes use of sun rays to give you a variety of car interior lighting mode. Just by the click of a button, you get your preferred light mode. You can have a clear mode which is perfect for winter or opaque during summer. You can also regulate the intensity of light entering the vehicle.

Light Strips

LED light strip also known as LED tape or ribbon is a flexible circuit board with many LED emitters mounted on it. The emitters can be mounted anywhere on the board to produce the pattern and lighting of your choice. Since they are available in a variety of colors a mixture gives an elegant appeal. They work perfectly for both cars and motorcycles.


Did you know that you can change the monotony of your wall painting? LED wallpaper is designed to kill this monotony. Just by a flip of a switch, you can change the shade of your walls into one that brings ambiance into space. For instance, you can change your bedroom into an ocean environment or your living room into a patio garden on a sunny day.

Sunshine in a Bottle

Sunshine in a bottle is a LED technology used for aesthetic purposes. The LED bottle is placed in the sun during the day to conserve heat energy from the sun. It is then lit up at night or placed in a dark room to give that aesthetic appeal. It gives a very appealing illumination like that of a setting sun.

Led Eyelashes

This might look weird right? But it’s the in thing nowadays. Most celebrities are using Led eyelashes to attract the attention of their audience. With the led eyelashes, it only requires you to tilt your head and give your audience that elegant illumination that leaves their eyes fixated to you. It’s a clever way of attracting the attention of your audience.
