Among energy-saving light sources, fluorescent lamps were the first to appear on the market. Without them, it is simply impossible to imagine modern offices, warehouses, large shops, as well as schools and hospitals. Such fluorescent lamps significantly save energy, are characterized by warm white radiation, high resource and affordable prices, which contributes to their widespread distribution.
They have a fairly long service life - up to 20 thousand hours, but subject to a minimum number of on and off cycles (under other conditions, they fail much faster).
Today, modern buyers are offered fluorescent lamps with high intensity. They contain chemical components that help smooth out jumps in the light spectrum. True, they are not able to project light over long distances, so they are used to provide visibility to nearby objects.
It should be noted that fluorescent lamps are most often produced in the form of glass tubes that are filled with a special metal powder and contain electrodes at their ends. They are characterized by a balanced color, which allows you to get a soft light, devoid of shadow. They are produced with a power of 18-36 W and a length of 60-120 cm, a light temperature of up to 6400 K, so everyone can choose the most suitable model for themselves.
In addition, compact fluorescent lamps are available in various forms - a regular bulb, a small spiral or in the form of a lotus. Their reflex species, which have a special aluminum coating, are also on the market. It provides a more directional
luminous flux, which is important to ensure an appropriate room design.
I must say that fluorescent lamps are indispensable in cases where it is necessary to illuminate an industrial or business premises, since they have a high return and give uniform light. They are characterized by compact size and beautiful appearance. In addition, they do not require professional connection, as they can easily be used instead of traditional incandescent bulbs and can be easily installed in a standard base. At the same time, technical light can be obtained not only with the help of fixtures of strict forms, but also with models that are made according to the latest trends in design art.
If we talk about gas-discharge fluorescent lamps, then they resemble neon signs and are glass flasks in which mercury and sodium vapors are used. The inner surface of such lamps is covered with a special composition called a phosphor and turns
ultraviolet rays into the visible spectrum of light.
It must be said that by adding separate impurities to the mercury-gas mixture of these lamps, one can obtain a luminescence of a different spectrum - white, color, or black (UV). If you use special quartz glass for their manufacture , you can get lamps that are used in medicine, since they are characterized by UV radiation of mercury and give a bactericidal effect.
