Today it is difficult to imagine life without the use of halogen bulbs. These products in their structure, characteristics and principle are largely reminiscent of conventional classic incandescent devices, but there is still a significant difference.
This is the gas with which a
halogen bulb is filled
, which includes various additives of bromine, chlorine, iodine. The use of such additives allows you to get rid of the effect of darkening of the flask, which is subject to conventional devices. Currently, due to its positive characteristics, halogen bulbs are widely used in many industries.
Some types of products may not have a large enough bulb volume. In this case, resort to the use of elite halogens as a filler, such as xenon. There is also a second way to solve the problem: increase the level of gas pressure.
A halogen bulb has a special principle of operation, which consists in creating special compounds on the walls of the flask. When turned on, decomposition of gases occurs, and their place is occupied by the evaporated tungsten atoms. The result is a tungsten halogen compound.
In the latest bulbs, methyl and methylene bromide are increasingly being used as chemical compounds. This is due to the fact that iodine enters into aggressive reactions with various metal elements of lamps, and the use of alternative halogens did not solve the problem, since they have even greater aggressiveness.
If we talk about quality characteristics, the halogen bulb has a longer service life compared to the classic options. This indicator is about 2–4 thousand hours, which exceeds the life of conventional incandescent devices by 3-4 times. Smooth start-up of products allows them to be used even longer.
A halogen bulb produces an optimal flow of light, and consumes much less energy. A quartz bulb allows you to protect the lamp elements from mechanical damage and temperature changes. Having a compact size, LED bulbs for the home are more convenient and comfortable to use.
Thanks to the development of technology, new developments of halogen lamps appear . One of the innovations is devices that are coated with a special layer that reflects infrared radiation. Such products are characterized by extraordinary light output: the coating allows you to reflect invisible radiation, passing at the same time visible light. These processes lead to significant heating of the spiral, which reduces the current supply. This principle of operation leads to significant cost savings.
Fields of application of halogen bulbs depend on the specific types of devices used. They can equally well be used to illuminate rooms or open spaces. Halogens allow you to emphasize certain parts of the interior, they are installed in outdoor appliances, used for window dressing, shopping centers, restaurants and shops.
