theme of this article - ceiling lights for offices.We understand, as they are;some lamps can be used in them, and how the office ceiling lights mounted to the ceiling.
What is it?
office lighting concept is rather arbitrary.So called lighting devices that are designed for large rooms and have high luminosity.
In addition, they have quite a distinctive appearance: as a rule, office ceiling lamp is a fairly dimensional square or rectangle with a simple reflector , several lamps, and often a protective grille.
Key criteria - the maximum luminosity in minimally decent appearance and reasonable price.
Note: LED office ceiling lights can be called affordable only against the background of other LED lighting systems comparable brightness.The price of 40-watt lamp in the Russian retail starts at three thousand.
What are they?
Strictly speaking, any light source with a bad design can be proud to call the office and sell at a reasonable price.However, in the traditional sense in that category until recently belonged only fixtures that use two - four fluorescent lamps in a plastic housing and provided with a reflector.
Initially, the Russian market was dominated by producing from the Soviet era the so-called fluorescent lamps - Discharge tube oblong housings;They hung from the ceiling.
Then with the advent of coffered ceiling (Armstrong and its analogues) lamps have become not suspended to overlap, and integrated into the suspension structure (also learn about the features of the installation of the suspended ceiling).
Currently in finishing a typical office space solution - ceiling of mineralnovolokonnyh or gypsum board.In the same rack and pinions design at intervals that depend on the required level of illumination, mounted ceiling luminaires for office.
However, progress was not a party and in the choice of lamps for them: conventional gas discharge tubes are increasingly competing successfully for office ceiling LED lights.
Advantages of LED lighting
Why growing popularity of LED lighting?After all, these lamps considerably more expensive than in the fluorescent lamps.Really substantial investments pay off in a reasonable time?
- LEDs emit light only in one direction .More specifically, in one hemisphere.To the side of the room, which they, in fact, will illuminate.At the same time, the fluorescent tube emits light in all directions.
course, reflectors pereotrazhayut him in the right direction;but not the reflection coefficient is 100%.From 25 to 70 percent of the light is absorbed inside the lamp.
- efficiency of the light source is also better for the LED lamp .The difference lies in the range of 30-50% depending on the type of LEDs.
- Unlike HID lamps, office LED lighting, ceiling allow you to adjust the brightness of the lighting .
Important: the use of conventional dimmers for incandescent lamps in combination with LED lighting, however, is not recommended.No, it will not burn;but the dimming range is small.Moreover, many LEDs may be color distortion.
correct solution is to use a special dimmers for LED lighting fixtures.Many of them, incidentally, have a remote control with infrared or radio control.
- absence of pulsations .Light discharge lamp flickers at a frequency of about one hundred hertz.The vision does not register ripple light;but the brain is tired.Of course, office lighting LED ceiling deprived of this lack of definition: LEDs light up continuously.
- Finally, discharge lamps contain mercury vapor.After breaking a lamp in the room, you get the inevitable poisoning;it will depend on the concentration of the vapors.At the same time, LED ceiling lights office no harmful substances are released under any circumstances (see. Lamps for suspended ceilings - a detailed review).
Pendant lights Pendant lights Office uses simple ceiling hangers - galvanized steel rods and PVC pipe, through one of which passes the power cord.The strength of the suspension is provided passing through the tube nylon cord.
mounting to concrete floors is simple :
- mark out holes for fasteners;
- ceiling zaburivaetsya puncher;
- The holes are driven plastic anchors and then fasten suspensions of the lamp assembly;
- lamp hung himself on a level.To adjust or thread used on steel hangers or mounting nylon cord to the lamp housing;
- lamp is connected to the wiring through the shoe, which is hidden in its body or in kabelkanale.
luminaires in offices are hung in rows at an equal distance from each other;a significant shift in the same row or different height fixtures look untidy.
Mortise office ceiling lights - LED and fluorescent - can in principle be fixed in any false ceiling.Of course if the corresponding manufacturing sheathing.
However their intended purpose - installation in cassette suspended ceilings Armstrong.Hence, the typical size - 595h595 mm, standard dimensions mineralnovolokonnoy or gypsum tile Armstrong.
Installation fluorescent lamp is reduced only to connect two wires and laying in the cell rack design (see. Recessed spotlights: types and installation options).
Office ceiling LED lights do not often use the built-in power converter and external power supply unit .This LED panel is served on the 12 or 24 volts.
However, given the structure of the coffered ceiling, the installation at the same time slightly more complicated.The power supply is placed on an adjacent tile;LED panel is connected to the terminals labeled "+" and "-" with the correct polarity;BP connected to the input of 220 volts.
Conclusion As you can see, in the absence of hard budget constraints the choice is unambiguous.For the future of LED panels, and the reasons for such a choice is very good and convincing.Success in repairs!
