theme of this article - LED ceiling light fixtures for the home.What are they?What are the advantages and disadvantages of this type of lighting?As can be mounted LED lights for ceilings?Let's try to understand.
Features LED lighting
begin with a brief overview of the properties possessed by all, without exception, LED ceiling lights.
Their list of over large on the background of competing solutions:
- Cost .LED lights turn out up to 22 percent of its electricity.You think it's a bit?Compare with 2.6% in the best examples of incandescent lamps.In addition, most of the losses - not LEDs themselves, and on converters and voltage regulators.
Note: the simplest converter is a diode bridge which converts 220 volts AC to DC of the same voltage.The LEDs are then connected in series.
- Low heat .LEDs themselves are heated very, very weak.The heat is dissipated again, the power converters.In fairness, with heat superbright LEDs have reckoned: the powerful lights can dissipate up to five watts of heat.The passive heat sink is necessary to ensure that mounting the fixture on the radiator.
- direction of the light in one hemisphere .Lamp LED ceiling does not need reflectors, pereotrazhayuschih light.Dignity is not far-fetched: on the reflector can be lost up to 70 percent of the luminous flux.
- Complete lack of discharge of harmful substances .As with the lamp and at its destruction.For comparison: in energy-saving fluorescent lamps contain mercury vapor, and the destruction of the bulb, in general, necessary to call degasifiers and evacuation facilities.If you do not care about the health of your loved ones.
- Ceiling LED lamp does not flicker .He thus favorably and incandescent and fluorescent lamps.Jitter alternative light sources is not recorded by the brain, however, greatly affects the fatigue of the eyes.First of all, when working at the computer and reading.
- lack of inertia - is also an important plus .LED lighting illuminates immediately and at full capacity.
- Small size LED lighting systems do allow extremely compact .For example, the built-in LED-suspended ceiling panels often have a thickness of less than a centimeter.The new line of LED lights mortise Fusion has a thickness of only 26 millimeters and an illumination angle of 160 degrees (see. Lamp LED ceiling bill: selection and installation).
- Finally, huge advantage , which have led ceiling fixtures against other lamps: cycles of on / off switch is not connected toLED life .
same energy-saving lamps with motion detector, for example, use is undesirable.Yes, and incandescent lamps with galogenki often fail when it is switched on.
They, in fact, only two:
- price.LEDs are rapidly becoming cheaper, but still remains the leader in terms of ruble per lumen light.However, the savings on electricity and maintenance and replacement lamps now make LED ceiling profitable.
- operating temperature.100C - the absolute maximum;Recommended temperature for LED - lights and all below 50 degrees.As mentioned above, high-power LED heat sink is necessary to supply, which again affects the price.
On set of the qualities of LED lamps for ceilings are clearly the best choice among all light sources.Of course, if you do not mind the cost.However, it has been steadily declining with the development of production.
types of fixtures
The fact that LED ceiling - it's good, we have already agreed.And it looks like the practical implementation of the concept?What are fixtures of this type?
Point Mortise lamps
They are mounted in false ceilings of various types of plasterboard, Pinion, tiled with a hanging system and PVC ceiling panels.This light fixtures directly cut into the surface of the ceiling fixed wire spring-loaded tabs (see. Spotlights for ceilings: accommodation options and Safety).
Posting in this case, should be ready by the time frame of the ceiling is sheathed with a decorative coating.
Adjustment of lighting in the tension protolok has its own quirks.Since even a small weight will cause sagging fabric lamp, use the special attached to the Draft ceiling platform.They, along with wiring installed before the ceiling will be stretched.
How to make LED ceiling using a point source of light, the most fault-tolerant ?
- Use only low-voltage LED lamp powered by 12 or 24 volts .They do not use their own power converters - the most vulnerable section of the lighting system.
- total for all fixtures PSU brought outside the ceiling, in a place that is convenient for maintenance and replacement.Remember when crashes LED lighting ceiling of 95 percent of the cases the problem is reduced to the problem is the power supply.
Inset spotlights may contain one or three high power LEDs a few dozen weak.In addition, they may be turning or have a fixed direction of light emission (see. Ceiling spotlights and chandeliers: the use and installation of a suspended ceiling).
first preference for the kitchen or office: lighting of the working area from several points not only provides sufficient light, but also to avoid shadows.The latter are mounted, for example, in toilets and bathrooms where directed light is not needed.
Tip: in wet areas should think about installing incandescent or galogenok.It is in a wet environment they are more fault-tolerant.If you choose here the ceiling mount LED - buy ceiling protected from moisture.They are easily recognizable by the IP parameters in the marking.The second number after the letters IP should not be less than 4.
These light sources are more in demand in the offices thanks to its hefty size and high luminosity: it can reach 5500 lumens, which roughly corresponds to polukilovattnoy incandescent lamp.
The actual power consumption of the lamp, mind you, is not more than 60-75 watts.
By way of mounting panels are divided into overhead, overhead and locks.The division is rather arbitrary and is connected only to that which is provided by the manufacturer mount housing.
Suspended LED-panel, nothing prevents put into the prepared groove plasterboard ceiling and used as a mortise.
sizes of panels quite a lot; the most popular are those LED ceiling lighting fixtures for homes that fit into the standard suspension systems coffered ceiling.It is above all panel sizes 60x60 and 120x60 centimeters .
These panels are simply being put in place between the rails of the ceiling tiles Armostrong or analogues thereof;then an electrician moving adjacent tiles, connected to the terminal bar pre-dilute the power - and lighting system installed.
This LED ceiling lamp serves one purpose: the creation of a specific directional lighting in the room.It is mounted to overlap, and the suspended ceiling.In the latter case, the installation is possible only to the frame profile or a wooden crate.
typical number of LEDs - one to three, with a total capacity of 3-9 watts.The outer casing is often the aluminum fins that improves the heat dissipation from bright LEDs.
Last ceiling light LED in our list - LED strip.In fact, it is a complex circuit with a few tens or hundreds of light-emitting diodes, made in a flexible manner and equipped with an external power supply.
Good to know about LED Strip ?
- Typical applications - ceiling lights.The tape is placed in a niche in plasterboard ceilings or special polystyrene cornice.At the same time the very source of the light is not visible;the viewer is available only the reflected light from the ceiling (see. LED strip under tension ceiling: a new level of illumination).
- ribbon is cut to length.For this purpose, it has a label on which it can be cut between the pads with a specific magnification - for example, every three LEDs.
- tape Do not bend with a radius of less than 2 centimeters - track easily torn.
- maximum length of whole tape - five meters.Need a great length - Please Hang second tape a pair of wires on the output power supply.Parallel to the first, but not consistently, otherwise there is a risk of burn tracks.
- These LED lamps for home ceiling include the most vulnerable spot lighting systems - power supply.Accordingly, in this case it is better to mount in a safe place without hiding in the ceiling.
Again: with all its features ceiling LED lighting - definitely the best choice for home lighting.Have a good choice and easy mounting!
