Lanterns in industrial buildings are special constructions, which are, as a rule, a glazed superstructure or a recess in the roof. They are used for natural lighting of the room, as well as for air exchange in accordance with the requirements of the process. They are installed in the pavilions, upper floors of multi-storey buildings, as well as in buildings of continuous development.
There are three types of lamps: aeration and light aeration, as well as light. By design features, trapezoidal, triangular, rectangular, M-shaped, Shedovye and anti-aircraft lights are distinguished.
Light device
This design allows you to provide the room with the necessary amount of sunlight. Such a lamp should have high light activity, which depends on the area and angle of inclination of the glazing of the structure. The best type of profile for a flashlight is considered anti-aircraft. Such elements of the building are highly luminous and light in weight. Trapezoidal and triangular lamps transmit light a little less intensively.
Aeration lamp device
Such lights are installed in rooms with a large release of heat, dust or gas. Air exchange through them is due to the fact that warm air from the room rises up and out through the holes. The created level difference and rarefaction of air contribute to the flow of air from the street through the supply openings, for example, windows. Most clearly, you can consider the principle of operation of the aeration lamp in the photo below.
With its equipment, the air outlet openings must be closed on the windward side so that the exhaust air does not get back into the building. It is believed that aeration lamps with an M-shaped profile have good aeration qualities. If there is a need to avoid direct sunlight in the room, then the ahed type of flashlight is perfect for aeration.
Light aeration lamp device
As the name implies, this is a combined type of design that combines the functions of light and aeration lamps. Most often, such devices have a rectangular structure, since with this approach it is most convenient to equip the sashes in vertical glazing.
How to choose the type, size and shape of the profile of the lamp
Of course, the choice of the type of flashlight directly depends on what functions it should perform. If a large amount of sunlight should penetrate into the room, then use anti-aircraft light lamps, which are openings in the roof of the building, filled with translucent material, most often - plexiglass. Also, anti-aircraft lights can be in the form of a porthole and can be located on the roof point above the rooms that need to be lit.
If the room should be well lit by natural light, but it requires a constant outflow of air from the building, resort to the installation of light-aeration lamps. In this case, they are usually rectangular or trapezoidal in shape. It is with such organization of the structure that light will penetrate well into the room through the upper glazing, and air will escape into the opening frames in the side vertical glazing.
In buildings with an increased amount of heat or harmful fumes produced during production, constant air renewal is required. In this case, aeration lights come to the rescue. In this case, the design profile is chosen so as to most effectively use the movement of air masses outside the building, as well as the temperature difference in the lower and upper part of the ventilated room. Most often, a rectangular type of flashlight is used for these purposes.
How to calculate the dimensions of a light aeration lamp
Despite the fact that the general view and type of the lamp depends on the room above which the structure is located, there are still standards by which the dimensions of the future lamp are determined. It can have a width of 6 or 12 meters. In this case, the design can be equipped with one or two tiers of opening bindings (sashes). In the first case, the tier height of the rectangular lamp will be 1.8 meters. In the second - 1.2 meters.
Six-meter lights are mounted over spans 18 meters wide, twelve-meter - over spans over 24 meters wide.
