Interesting Facts About Light Emitting Diodes (LEDs)

October 29, 2018

Light-Emitting Diodes – commonly known as LEDs, are a device that uses semiconductors in order to make light when a current passes over it. An LED light bulb is the most energy efficient bulb on the market today, as it doesn’t emit lots of heat. Actually, it integrates a heat sink which absorbs heat. As a result, it will not overheat or burn, which explains why LEDs tend to last longer compared to their counterparts such as CFLs and incandescent.

6 Essential Facts About LEDs

  • LEDs are Energy Efficient


LED lighting converts 95 percent of the energy consumed into light, compared to other traditional lights like incandescent bulbs that only convert 10 percent of energy.

  • They are Great for Gardening


Hyper red and deep blue LEDs can offer light for photosynthesis. While far red regulates the plant from propagation to vegetative development, as well as flowering.

  • A Blue LED Can Keep Food Fresh


LEDs especially the blue ones have been proven to have a resilient antibacterial effect on most foodborne pathogens. As a matter of fact, they’re now being utilised in fridges.

  • The Brightness Of LEDs Is Not Measured In Watts But In Lumens


Usually, when we are buying a lamp we are always looking at the wattage in order to identify its brightness. Conversely, LEDs are measured differently. Actually, wattage displays how much energy is drawn, instead of the brightness.

  • LED Lights Don’t Feature The Same Colour


When you are buying LED lights, you may possibly imagine that like traditional bulb the colour will be the same. But the truth is LED lights might differ. Some of them can give off a cool blue light while other LED lights show a warm light.

  • Usage


LEDs perform lots of various jobs like lighting up timepieces, forming numbers on a digital clock, forming photos on big TVs, and transmit data from remote controls.

In addition, LEDs are also used as a replacement for aviation or traffic signal lighting, and even automotive lighting.

Actually, the very first marketable LEDs were usually utilised as a replacement for neon indicator and incandescent lamps, as well as in seven-segment displays. Normally, they are integrated into cheap equipment like electronics and laboratory equipment. And after a couple of years, they are already in various appliances like televisions, telephones, radios, and calculators.

Other Interesting Facts About LEDs

  1. – LEDs do not attract many insects compared to other traditional lights since they only contain very small UV.
  2. – LEDs with good quality may possibly last for over 50,000 hours.
  3. – The Time Square Ball which is located in New York is illuminated with more than 32,000 LEDs.
  4. – LEDs bulbs are mercury-free.
  5. – The first LED lighting was made by Nick Holonyak in 1960s.
  6. – LED bulbs that are hundred 800 lumens is equal to 60 watts incandescent bulbs.
  7. – Unlike CFL and incandescent bulbs, LEDs give off light in a particular range, using energy and light in a more efficient way in several applications.
  8. – On average LED lights aren’t subjected to severe destruction from external shock.
  9. – Since LEDs don’t contain mercury, more than 96 percent of their parts can be recycled.
