How Does Infrared Technology Work?

Did you know that infrared is applied in almost every sector? This includes science, health, entertainment, and industry.

How does infrared technology work?

Nearly all objects on earth emit heat, which is the common source of infrared. However, if the heat is not enough, energy is emitted in the infrared spectrum. Infrared (IR), therefore, is a wavelength of energy invisible to human eye. It is part of electromagnetic spectrum.

Some of the common uses of infrared are heating, night vision, imaging, communication, and tracking. But for now, we’ll only look at heating and night vision.

Let’s get started.

Infrared heaters versus convection heaters:

Have you realized that infrared heaters are becoming more popular? This is because people have realized the amazing benefits they have. To cut the long story short, unlike convection heaters which warm the air itself, infrared heaters will heat up every object in the room including you.

With this kind of technology, you’ll be able to cut your heating bill by a half. The essence is that almost all the energy around will be converted into heat.

Sound good?

How do we go about choosing an infrared heater?

Choosing infrared heaters for home heating needs is not tricky as most people tend to think. By now you should know that infrared heaters are energy efficient – but how do we know the best ones?

Let’s dig in.

Some of the Best Infrared Heaters 2017:

  1. Homegear Pro Large Room Infrared Heater

This heater is smaller in size and one of the cheapest options.  It has a durable plastic exterior and an LCD. The LCD displays temperature, thermostat settings, power control, and timer.

  • It has a blower fan that distributes heat evenly and a remote control so that you operate it at the comfort of your chair.
  • It weighs about 11.5 Ibs with 1500 W of power, enough to provide for a 1,000 sq. ft room.
  • If you are cash-strapped and don’t mind the style, this is the way to go.
  1. DR Infrared Heater

It is one of the most energy efficient infrared heaters. It has three power modes to maintain the temperature. It is a portable heater best for both small, medium and larger room. It can heat up to a 1,000 sq. ft room, with a minimum and a maximum temperature range of 50 °F to 86 °F respectively.

  • It is portable and can be wheeled around easily. You’ll also be provided with a remote to help you operate it from the comfort of your chair.
  • The heating is supported by the quartz and dual PTC. It also has a blower that distributes heat evenly.
  • When it comes to safety, it has an automatic shut-off mechanism. With this kind of heater, you needn’t worry about winter.
  1. Duraflame DFI-5010-01 Infrared Quartz Fireplace Stove

The Duraflame DFI-5010-01 infrared quartz fireplace stove keeps improving day by day. It has mesmerizing 3D flame effects that are usually displayed on a flat screen, the flame effects look real.

To sum it up:

Most infrared heaters are portable, small and lightweight in nature. But some are meant to be fixed permanently whilst others are meant to be wheeled around from one room to another.

How Night Vision Technology Works   

Let’s first see how light works. In lightwave, the amount of energy is related to wavelength. The shorter the wavelength the higher the energy. In terms of energy – when it comes to visible light, violet has the most while red has the least.

Still wondering how night vision technology works? For easy understanding, we can divide infrared light into three categories:

Let me explain.

Thermal-infrared (thermal-IR):

In the infrared spectrum, thermal-infrared occupies the largest part. Its wavelengths range from 3 microns to about 30 microns. Unlike others that are reflected off it, thermal-IR is emitted by an object directly due to motion at the atomic level.

Mid-infrared (mid-IR):

Its wavelengths range from 1.3 – 3 microns. Mid-infrared is used in electronic devices such as remote control,

Near-infrared (near-IR):

Near-infrared is closest to visible light and has a wavelength that ranges from 0.7 – 1.3 microns.

Conclusion

Infrared technology has been very useful in many ways and this has helped improve how humans live. Among the common uses of infrared are thermal imaging cameras, night vision equipment, remote controls devices, and infrared sensors.

Infrared technology has helped make the world a better place. Scientists will keep on discovering new things – and to continue with this journey, they must keep on inventing new technology. Are you embracing new technology? Well, keep learning and become innovative.
