Dozens of appliances used for heating are on sale today. Recently, an infrared heating lamp has gained considerable popularity. This type of device is a compact source of infrared radiation, which is screwed into a simple ceramic cartridge – although there are models for which special cartridges are required. Currently, infrared heating has become an alternative to traditional batteries and conventional electric heaters with heating elements (heating element).
Infrared lamp design
Infrared lamps for heating are autonomous heating devices that are powered by an electric network. They are a source of infrared radiation that reaches the surrounding objects and heats them. The simplest version of the device is presented in the form of a simple glass bulb, inside which is a tungsten filament. Glass is often painted brown-red. A mirror coating is visible from the inside. Such a bulb is screwed into a cartridge enclosed in a housing or suspended above a heated space.
There are compact IR lamps for heating rooms, which are made in the form of thin glass tubes – a mixture of argon and nitrogen is pumped into them. The result is a miniature bulb with a decent heat flow. It functions thanks to a tungsten filament, like a conventional light bulb, which is designed to illuminate rooms.
The infrared heating lamp is a compact source of infrared radiation with a power of 50 to 500 W, although more powerful devices that are used in heaters can also be found on sale. During operation, the case of the device can warm up to high temperatures, for this reason the cartridge of the device should not be made of plastic, otherwise it will soon melt. Do not touch the infrared lamps, as there is a chance of getting a burn.
Principle of operation
The principle of operation used in IR lamps was invented by nature itself. Everyone knows that the most powerful source of infrared radiation is the sun. Its rays reach the surface of the Earth and the objects located on it, warming them. As a result of this, they begin to transfer heat to the air. It turns out that not the air itself, which is a good heat insulator, but the elements of the landscape and buildings that were created by mankind are heated by sunlight.
The infrared lamps for the home work in a similar way. Infrared rays, instantly reaching any objects, are absorbed by them, after which they turn into thermal energy. For this reason, by placing your hand under the light source, you can feel the heat spreading inside you. Devices of this type warm rooms more efficiently than many analogues and at the same time do not waste energy.
The brighter the device shines, the more short-wave radiation it gives, and the further its rays propagate – thanks to this it is possible to heat rooms with a large area. Long-wave models are not so bright, but more gentle and soft heat comes from them. Radiation from such lamps does not have a detrimental effect on living organisms, including humans – subject to reasonable use. Some types of devices are used for physiotherapy to treat various diseases..
Types of IR Lamps
Modern manufacturers offer a choice of several types of IR lamps. In total, there are four of them:
- without mirror coating;
- with a mirror coating – differ in silver flasks;
- with a red mirror coating;
- blue mirror coated.
The first types of bulbs are outwardly similar to conventional incandescent bulbs, but they also represent a source of infrared radiation. Powerful luminous heating elements (electric heating elements), which are equipped with halogen infrared heaters, are also lamps, but they are more efficient and designed to heat rooms with large areas.
The remaining types of bulbs are equipped with a special mirror coating. Such a coating is necessary to increase the efficiency of the devices and in order to direct the IR stream in a certain direction. In the absence of a reflective coating, external reflective elements can be used as it – this is implemented in halogen infrared heaters. Sometimes IR lamps are combined into one design to get a powerful IR illuminator.
In addition, the traditional IR lamp in the form of a conventional bulb under the E27 base has a certain marking in the form of an abbreviation. The designation “X” indicates that the product is not painted in any colors and can be used not only for space heating, but also for lighting. The abbreviation “IKZK” indicates the presence of a red color, and “IKZS” indicates that the product is blue. IR devices differ from each other also in several characteristics, which include:
- Type of cartridge (cap). Equipped with traditional size cartridge E27.
- Wavelength. Depending on this parameter, the devices are long-wave, medium-wave and short-wave.
- Power. Varies in a very wide range.
- Supply voltage. For almost all household IR bulbs, this indicator is 220 volts.
An IR lamp has several important advantages, thanks to which its popularity is growing from year to year. They are:
- Full silent operation. Compared to heat guns, infrared radiation propagates without any fans or other devices..
- Maximum efficiency (coefficient of performance). As with most other electric heating devices, it approaches 100 percent – this indicator does not reach because of certain laws of physics.
- Possibility of spot heating. This is true for animals that are kept in pens, small cages. For example, IKZK are widely used in the field of animal husbandry, where they are used to heat poultry houses, pigsties and other places of keeping animals..
- Compactness. A 500 W standard IR lamp is comparable in size to a conventional incandescent bulb.
- The simplest installation. You need to screw the infrared bulb into the cartridge, then click the switch.
- Environmental friendliness. IR devices do not burn oxygen and do not emit any gases into the surrounding space.
A device such as an infrared lamp is not without flaws. For this reason, be sure to take them into account before purchasing an infrared lamp for heating. The cons include:
- High power consumption. This is typical for any heating appliances that are powered by the mains..
- Discomfort with prolonged exposure to the light bulb. In this case, non-compliance with certain operating standards is more often affected..
- High temperature flasks. There is a risk of serious burns..
Scopes of infrared lamps
Despite the shortcomings, the infrared lamp continues to use the demand for heating various rooms. The scope of its application is wide – it is necessary not only in everyday life, but also in production, in the medical industry, etc. Especially often, infrared bulbs are used by agricultural workers and people who specialize in raising livestock and poultry. They gained some distribution and for heating of the open areas.
For heating animals
Devices with infrared radiation are well suited for breeding animals, so they are used in chicken coops, pigsties, cowsheds, stables, etc. Infrared radiation to heat the chicks helps young animals survive and not freeze. Birds with pleasure huddle right under the device, enjoying the heat released from it. In the same way cells with animals are heated, where a thermal infrared lamp with temperature control can be useful.
Such devices are especially in demand in chicken coops. Their use helps to provide birds with the necessary level of heat and create a comfortable atmosphere even in extreme cold. They cease to feel discomfort from the cool air and freeze. The bird’s immune system is growing stronger, and the risk of disease among them is sharply reduced – this is very important for laying hens, because comfortable, stable temperature helps them to lay eggs regularly.
The same devices are used in zoos, terrariums and on farms where newly born animals are planted in separate boxes, cages. To make them comfortable and warm, low-power bulbs are installed above them. In terrariums where snakes, turtles, reptiles and other amphibians live, a heat point is made using an infrared lamp. It is a place where reptiles get out to bask. Exposure to radiation will warm the animals for 3-5 minutes, and the absence of bright light will positively affect their nervous system, preserve sleep.
For space heating
An excellent basis for a street heater is a halogen infrared lamp. With a short wavelength and low power, relatively large areas are heated with its help. Heating appliances, supplemented by such bulbs, are widely used on verandas, terraces, near pools. They are used even in open areas of cafes and restaurants. The infrared rays emitted by them quickly reach people, pleasing them with warmth, comfort.
In outdoor conditions, they are almost the only way to heat, because conventional convectors, heat guns will be useless. Tube IR heater is great for heating commercial and residential premises. By installing such appliances on a wall or ceiling, you will get a good source of heat. A short- or medium-wave light bulb will quickly create an atmosphere that is comfortable for people to stay. Heaters of this type are rarely used on an ongoing basis – they are often used as auxiliary equipment for poor basic heating.
For the sauna
Through infrared lamps, the body warms up from the inside, because infrared waves easily penetrate to a depth of about 4 cm, having a positive effect on the joints, skin, and the system of internal organs. The use of such heaters in saunas contributes to weight loss. Excess liquids, along with slag and toxins, are actively eliminated with sweat.
At the same time, blood flow improves, and energy consumption of the body increases, which provokes the burning of calories. With regular visits to infrared saunas, you can successfully deal with various kinds of skin lesions, for example, dermatitis, eczema, etc. Staying in an infrared sauna makes the walls of blood vessels elastic, reducing the risk of developing heart and some other dangerous diseases.
For drying paint and working with plastic
Processing various materials and drying them with an infrared light bulb is a profitable and practical way, which is used both by small workshops and large paint and varnish workshops. Tumble dryer can work precisely: the heat from the device is sent to the area of the item that needs to be dried without heating its other zones. For example, when drying the hood, not the entire car heats up, but only the hood.
When working with plastic, radiation contributes to its straightening, softening, flexibility and molding. In addition, they participate in shrinkage, drawing, extruding objects from plastic, representing an effective tool. Such bulbs are also used by printing houses, where they release paper from excess moisture – drying with heating is faster. The result is high-quality printing.
For heating greenhouses
With the help of infrared radiation, an optimal atmosphere is organized in greenhouses, because plants receive the same rays from the sun. Such heating will be a plus for the development of crops. To do this, use a lamp for an infrared lamp or adapt single products that hang on the wires above developing plants. This type of lamp is suitable for those who grow seedlings on the windowsill. Plants will not lack heat, lighting. The main thing is not to overdo it with the selection of power, the duration of the backlight.
The treatment with infrared light bulbs is a bit forgotten. Previously, IR lamps were widely used to eliminate pain symptoms, treat osteochondrosis, and pain in bones and muscles. They also helped with flu, throat diseases, acute respiratory infections, skin diseases and high blood pressure, they strengthened the immune system, relieved stress, removed bruises, and increased stamina..
At present, the treatment with infrared lamps is again gradually reviving. People began to trust tablets less, recalling the beneficial effects of physiotherapeutic procedures. Treatment with infrared rays belongs exactly to the field of physiotherapy. The infrared spectrum is effective in the treatment of acne, which is important for people who are concerned about problems with the skin.
