A fluorescent lamp or a fluorescent lamp is the main device for lighting premises during daylight hours. Their main advantage is their relatively low power consumption at a high level of illumination.
Instructions
Step 1
A fluorescent lamp is a gas-discharge light source. The main light source in a fluorescent lamp is a phosphor. Typically, an inorganic material is used to create fluorescent lamps. The backlighting of the phosphor is provided by ultraviolet radiation of the discharges, which, in turn, are also a light source.
Step 2
The obvious advantage of fluorescent lamps over incandescent lamps is their service life. It is important to understand that a tenfold difference is achieved only if the quality of the power supply is observed. In addition, fluorescent lamps have a limit on the number of on / off switches.
Step 3
The principle of operation of the described lamps is to illuminate the phosphor with an electric discharge. A change in the shade of the glow, as a rule, is achieved by changing the composition of the phosphor. In addition, the presence of this substance helps to contain harmful ultraviolet radiation.
Step 4
For lighting industrial and residential premises, as a rule, low pressure fluorescent lamps are used. These devices are not suitable for providing the desired level of illumination outdoors. High pressure lamps are used on the streets.
Step 5
Fluorescent lamps are widely used in the following objects: schools, hospitals, warehouses, offices, and so on. In addition, it is worth highlighting the type of "energy-saving" lamps. This is a modification of fluorescent lamps that connect to sockets E27 and E14. They are increasingly being used instead of conventional incandescent bulbs. It is important to understand that the long service life of these devices is ensured only if they are rarely turned on / off.
Step 6
It should be noted that modern plasma displays are nothing more than a modification of fluorescent lamps.
