It is in 1800 that William Herschel, a famous English astronomer, discovers that the infrared is the light of the spectrum which releases the most heat. Still, it is necessary to wait after the First World War to see the beginning of the commercialization of the lamps with infrared rays. Because its radiation has an undeniable utility in many areas, the use of the infrared light has spread widely over time.
The operation of the infrared lamp
The infrared lamp produces a light invisible to the human eye because its frequency is lower, and its wavelength is higher than the other visible colors. The operating principle is based on the temporary increase in the temperature of the zone towards which the lamp is oriented.
- This is how the infrared lamp can illuminate objects, humans, and animals at night with rays not visible to the naked eye.
- In the medical field, the infrared lamp relaxes and soothes pain by delivering heat to a particular area.
- Used in industry, the infrared lamp heats materials faster.
In the domain of health
Since the 1980s, infrared lamps have been used by doctors and physiotherapists because they can effectively relieve patient pain or improve certain functions.
- Massages provided by physiotherapists and physiotherapy sessions warm the human body by spreading heat in the body evenly and reducing joint pain and muscle tension. Infrared lamps are used to fight against diseases that cause chronic pain, including polyarthritis, fibromyalgia, or ankylosing spondylitis.
- Increased blood circulation: By increasing the temperature of the treated area, the infrared lamp helps to irrigate it better, improve tissue repair, and eliminate toxins. The advantage of the infrared light is that you control the temperature precisely.
In the field of cosmetics
As the infrared lamp produces heat, it is used cosmetically. The pores open, and the skin expands, sweats, and releases the toxins, allowing the cleaning products to penetrate deeper and thus better remove impurities. The heat, which also has a stimulating effect on the production of collagen, contributes to the rejuvenation of the skin.
In the exercise of professions related to surveillance and security
As the infrared lamp produces an invisible light by humans and most animals, it is a real night vision accessory, primarily for surveillance and security professionals. The infrared lamp allows seeing without being seen night objects and people even far enough away without lighting the area.
Infrared heaters are now widely used in homes because they provide higher welfare by heating by radiation and can reduce energy consumption, thus saving money.
Many industries use infrared lamps to heat materials. This is particularly the case of the automotive sector, textile, food processing, or plastics. This technology saves time and reduces energy consumption, which leads to lower production costs and consequently, higher productivity.
Infrared lamps are also used in terrariums to produce ideal heat to provide reptiles with an adequate place to live and maintain their body temperature. This aid to the thermoregulation of the metabolism of reptiles favors their appetite, their digestion, and their activity in general.
Since the beginning of its commercialization almost a century ago, the infrared lamp has seen increasing use because it offers multiple benefits: it allows night vision, relieves pain, and optimizes industrial processes such as heating systems. The comfort of use it presents is certainly not foreign to the fact that it is used in many areas.
