LEDs in home interior - fashion spreads literally by leaps and bounds.Initially, they were used in an emergency and the local light, but are now widely used for interior decoration, and more - for the main lighting domestic premises.
LEDs conquer their efficiency, reliability and environmental friendliness, the vast scope for design ideas and ease of installation: handyman quite capable on their own, without the help of professionals to realize their "light" fantasies.Many users FORUMHOUSE long appreciated these opportunities and are successfully used LED lights, lamps and tape not only for supplementary lighting plants and outdoor lighting house and land, but also as a decoration and general lighting in their homes.It is time to summarize their experience.
Advantages of LED lighting:
reliability and safety of use.
durability, high service life.
resistance to vibration, humidity and temperature variations.
Opportunities for design and decor.
Ability to adjust the light intensity and color changes.
No harmful ultraviolet radiation.
main disadvantage of LEDs is still their high cost.And although every year they are becoming more accessible, use LEDs as the primary light in large rooms - very expensive, which does not pay for itself in energy savings.However, if this is necessary?Like any fashion trends, even the most useful and make life more comfortable, to use LEDs for home lighting should be treated with caution.Inspired by the properties of "magic crystals" and encouraged by the sellers, many householders tend to mount LED-lights and ribbons everywhere, even in the bath with a sauna.In terms of comfort and economy is not justified in all cases.
popular today LED ribbon intended primarily for decorative lighting and only secondarily - for lighting.Doing basic lighting using LED strips - expensive and uneconomical due to the high power consumption.Feeds on the ceiling and the walls are placed in niches, profiles of cornices and so on. N., And therefore have a very low utilization efficiency of light: basically you'll see only the reflected light, at times less than the tape outputs.The rest remains in the niche.
many inspiring idea of ​​"glowing" ceiling.But to implement it using LED strips have to invest thoroughly.First, it requires expensive high-quality components.Saving them may subsequently result in a loss if you have to dismantle the ceiling due to their failure tapes emerged.In addition, the quality of the ceiling mount the tapes - no easy task.For evenly illuminated surface of the LEDs must be placed in such a way that any axle spacing between them was the same and less than the distance to the scattering plane, explains forumchanin Egor Kirov .If you do not meet these conditions, the ceiling will be illuminated unevenly stripes.Tapes have to be reduced so close to each other, and will need a lot of them: up to eight or nine lines on the meter.Economical and low this type of lighting is clearly not name.
- Characteristics tape does not exceed the value of 50-60 lm / W, while even the Chinese shirpotrebovsky fixtures it starts from the value of 80 lm / W, while good fixtures - 100-120 lumens.Stated tape options for luminous flux manufacturers often overstate.Yes, and economic sense in the film when the impact of 750Lm / meter, to put it mildly, incomprehensible.
Even in small spaces, such as in the hallway, using tape as the primary light source will have to take them brighter and more powerful: 9.6, and preferably 14.4 watts per meter.
Another thing - highlighting of individual elements of the interior.Here, LED strip will be very useful.Placing tape around the perimeter of the ceiling of a small room, you can visually expand its size.In a large room will work effectively in conjunction with the primary light from the lamps, tape, illuminating the different levels of the ceiling.In the kitchen, LED-backlight band perform the work surface or bar, the inner space in the closets.
power adapter tape required to exceed the total power of the LED, it is better to reserve.Calculate the power by the formula: footage of the tape capacity * 1 * 1,3 m tape = minimum required power supply unit.For example, for a meter ribbon capacity of 14 W / m power supply is required at least 1 * 14 * 1.3 = 18.2 watts.
lot of useful practical information about the features of the installation of LED strips and advice from experienced users can be found in this section FOREMHOUSE.
another, is rapidly gaining popularity, the option of LED lighting products - LED-panel .They are available in different colors and sizes, have low power consumption with high light output, and therefore can be successfully used for general lighting, especially in small and medium-sized environments.LED panel can be very thin (8-25 mm), and are therefore well used in homes with low ceilings.
panels can be mounted on suspension systems, embedded in the ceiling or wall niche.Universal mounting to successfully use them for visual separation of space into separate functional areas.The panels of different shapes and different colors fit to emphasize certain parts of the interior.In the hallway, hallway, bathroom best option may be several panels 12-15 watts of power, placed on the ceiling at a distance of 1.2-1.5 m from one another, advises the user forum Dale85 .For the main lighting is not necessary to choose the panel with a cold glow (marking White).
When choosing LED lamps and luminaires it is important to understand that if the traditional incandescent lamps was a direct connection between "higher power - more light", the LED is not the case.Choosing LED-lamp, based solely on its power consumption would be a mistake.
criterion of efficiency LED lamp - luminous efficacy, showing the amount of light a lamp or luminaire studies per watt of capacity. It is measured by the ratio of luminous flux output - lumens / watt (two of these parameters must be specified by the manufacturer on the packaging of the lamp).The higher luminous efficiency, the brighter the light.
Modern LED lamps have an average light output in the range of 90-130 lm / W.In comparison, the traditional 100-watt incandescent light bulb "outstanding" luminous flux maximum in 1200-1300 lumens, ie its light output - only 12-13 lm / W.
often on the packaging of LED lamps manufacturers place the information
that the power of the lamp is equivalent to power incandescent bulbs of the same brightness.It would seem that this helps the customer to make a choice, guided by the familiar setting - power.But in fact, such information may be misleading.For example, if the package 4-watt LED lamp with the declared luminous flux of 280 lm is written that it is equivalent to the parameters of a light 50-watt incandescent bulb - is the obvious duplicity.The intensity of the light flux incandescent 50W twice as high - 500-600 lumens.
When choosing LED-lamps must also be borne in mind that the brightness of the lamp in fact will always be a little bit lower than specified by the manufacturer the brightness of LEDs, which it used as the efficiency of power supplies is typically less than 80-85%, and about 10 morepercent of the luminous flux can be "lost" due to the reflector and glass.
Egor Kirov:
- If today's typical LED light output at 110-130 lm / W, the spotlight (lamp), made the most of these LEDs, the ratio is due to loss of performance (COP) of the driverat the level of 80-100 lm / W.
Choosing LED-lamps and accessories for them, do not forget to check with seller warranty coverage, ask whether the luminaire to be repaired.And do not chase the cheap: unreasonably low price for LEDs - a sure sign of poor quality.Lamps with low-cost crystals, most likely, will not "give" declared parameters, and may at any time withdraw from the system.Simply save the chandeliers in the luminaire body.
- Many comrades buy, for example, housing for recessed luminaires for 1500-2000 rubles (though they are not visible when the light, and does not look anybody in the lamps) and a light bulb in the lighting wantsBuy for $ 100, but to the ages.Savings on buildings allows you to buy a normal LED lamp.
