The fluorescent lamp acts as a gas-discharge light source, in which the visible brightness is mainly created using a phosphor driven by ultraviolet light from the discharge.
The light output from the product is several times greater than that of simple
incandescent lamps with similar power indicators.
In addition, the fluorescent lamp has a longer service life, which can exceed the period of operation of a conventional device by twenty times. This is possible with high-quality power supply, observing the restrictions on the number of turns on and off the device.
You can buy fluorescent lamps in almost any store that sells lighting devices. The most widespread mercury gas-discharge devices of low and high pressure. The latter type is mainly used for arranging street lighting, as well as in high-power lighting installations. Low pressure devices are usually used in industrial and residential premises.
The fluorescent lamp is widely used to create lighting in public buildings: schools, hospitals, offices, etc. With the advent of compact devices with electronic ballast that allows you to insert lamps into ordinary cartridges, fluorescent products are becoming popular in everyday life.
The demand for devices is due to their characteristics. First of all, they have high light output (a 20 W fluorescent lamp shines like an ordinary 100 watt), long life (about 2000 to 20 thousand hours versus 1000 for an ordinary incandescent lamp), as well as diffused light and a wide variety of shades.
It is more expedient to use devices to create general lighting in rooms with a large area. It is most effective to use products together with Dali systems that can improve lighting conditions, while energy consumption is reduced by more than half, and the duration of the devices increases.
A fluorescent lamp is also widely used in workplaces, in light advertising, to improve the appearance of building facades, etc. Devices find their place in the backlight screens of LCD monitors and televisions. A variety of products are plasma panels.
Luminescent devices have characteristic features associated with the principle of operation. When the lamp is turned on, an arc of a low-temperature electric discharge runs between two electrodes located at different ends of the device. The lamp is filled with inert gas and mercury vapor, which allows you to cause UV radiation that is not visible to humans. It is converted into light using the luminescence effect.
For more stable operation of the devices, special ballast electronic devices (electronic ballasts) for fluorescent lamps are used. They ensure reliable functioning of the luminaires, excluding buzzing and blinking, while power consumption is reduced by a quarter.
