What is an IR bulb?

IR bulb is a type of illuminator that projects infrared light. Traditional bulbs emit visible white light that can be easily seen with the human eye. On the other hand, light from infrared bulbs cannot be seen directly. This type of bulb is often used in night vision, heating, communication and health applications.

Not all light is visible. The light that people can see is between 400 and 700 nanometers (nm) at the wavelength. The highest wavelengths in this range are produced by red colors. IR has a wavelength that is higher than red, and it cannot be seen with the naked eye. The infrared spectrum is located between 0.74 micrometers and 300 micrometers in the wavelength. The range of night vision is one piece of technology that is designed to use infrared light. These devices intensify light from visible and IR range and convert this light in the picture can be interpreted by humans. Police and military forces often use high -performance infrared bulbs tohidden scene lighting. Staff with night vision ranges are usually able to see more clearly while other people see only darkness.

Infrared bulbs are also useful for providing heat. IR waves emitted from infrared energy transfer of bulb, which is absorbed by nearby objects. This energy absorption causes the object to warm up. The heat created by IR bulbs is commonly used in saunas. Infrared heating is also used in applications such as ice removal from aircraft and in some industrial production.

It is assumed that the heat generated from infrared bulbs has benefits for health. Light therapy, also known as "phototherapy", commonly uses IR heat sources to support healing. The infrared light light is used to alleviate skin disorders and also for reducing pain caused by injuries. Medical use of infrared bulbs is often considered more natural and holmore istical than drug use.

One of the most common uses of IR bulb is to communicate with short reach. Information can be sent by pulsing the IR light source in the pattern. It is similar to the fact that the traditional bulb turns on and shuts down to send the Morse code. Infrared light is less prone to interference than visible light and can be easily detected by room devices. TV remote controls and ports of data mobile phones are two examples of infrared bulbs used for this purpose.
