Rates of LED lighting in different spheres of life are growing every day.It captures more and more scope for civil and industrial character.And it all began with only emergency and local lighting.Now it is possible to easily install LED lights with their hands, using it as for decorative purposes and as primary light.

## Sober calculation - the basis of success ↑

### Selection of the power supply for LED strip ↑

LED ribbons are available in rolls of 5 m length, each meter can be set from 30 to 120 pieces of LEDs.It is not necessary to use all of five meters.If

you plan to light a smaller portion can be cut to the desired length.Just to anywhere, of course, can not be cut.The multiplicity of cutting should be at 3 LEDs, most space possible cutting designated by the manufacturer.

LED Strip can not be connected directly to the network only to the power supply.To find the required power supply, it is necessary to know the total power consumption of the entire tape used.

Examples of calculations:

We acquired the tape SMD 3528. Its length is 5 m, the operating voltage of 12 V, the number of LEDs per meter 60 pieces, and power consumption - 4.8 W / m.In other words, each meter of our tapes consumes 4.8 watts.All these parameters are indicated on the tape itself or the packaging.

length area that we want to highlight is 7 m. So, one tape is not enough.Not buy another cartridge 5 m length and cut off from her 2 m, which we need.

Power consumption of the tape: Ptot = Pm * L = 4,8 W / m * 7 m = 33.6 W;

Where,

Ptot - total power consumption of the entire tape;

Pm - power consumption of one meter tape;

L - the length of the tape.

Total, total power consumption has turned the tape 33.6 watts.But to ensure the proper operation of the power supply is necessary to make the power supply of 20%.

P = Ptot KZ = 33.6 * W * 1.2 = 40.32 W;

Where,

P - the required power supply unit;

KZ - the safety factor (20% - in this case).

Now the catalog power supplies for LED strips must be selected such that the power of which is close to 40.32 watts, but not below.

### Calculating the number of LED lamps ↑

LED lamp can be used in false ceilings

LEDs have ceased to apply only as decorative lighting.New production technology of super-power LEDs allow you to use them as a head light in the house or apartment and even at work.

Calculation of LED lighting in this case is made in view of building codes, SanPin and other regulatory documents to ensure comfortable conditions, livelihoods, or workflow environment.

To calculate the number of LED lamps and illumination distribution can take advantage of special programs that are freely available for download on the Internet, for example, DIALux.

If exact data are not necessary, you can try to do the calculations yourself - semi skilled way.First, we determine what we want to highlight, rather than any existing lights will use LEDs.For each task, require different lighting, be it light floors, head lights in the room, light furniture or ceiling.

For calculations, we need only one parameter - the luminous flux.This kind of brightness, light intensity, measured in lumens (lm).The manufacturer is required to indicate the value of the luminous flux on its products, including the LED lamps.The calculation will be done based on the fact that the 100 watt incandescent light bulb shines for about 1200 - 1300 lm.For example, to replace the light bulb in the toilet at 60 watts will need to find a LED lamp with a light output of 600 - 700 lumens.

If insufficient information on the package, it is possible to perform calculations, based on the power of the lamp.Most often, LED bulbs consume 5 watts to 12 watts.With about light output at 1 W 50 - 80 lm.There may be more, but we will be taking to a minimum - for lighting the room 50. 18 m2 must be 2500 lumens.Divide by the smallest possible luminous flux of 50 lm at 1 watt.Get 50 watts.It should be a total power of LED lighting in the room.But how to choose the 10 fixtures at 5 watts each, scattered evenly throughout the room, or 4 powerful lamp to 12 watts - you decide.

## Design LED lighting ↑

such an important aspect as design, best left to professionals.And not just because it is their daily bread, but because they have to face a number of difficulties.Draft electrical and lighting a home or apartment do not need to change because the load on the network does not increase and decrease.The complexity of the design of LED lighting with associated technical and optical characteristics of the LEDs.For example, light reflection, the angle of light emission, the operating temperature, the luminous flux - are crucial, and such details as the color of the walls and ceiling, can dramatically affect the comfort lighting.

## Mount with his hands ↑

### Installation and connection of LED strip ↑

determine how long the site want to highlight the tape.If it is greater than 5 m, not buy the required number of tapes and cut the length of the missing.With a single power supply can be used a maximum of 15 m tape (cassette 3).

then solder wires between the segments.At the ends of the wires wear contact tips to improve the quality of contact between the wire and the power supply.Isolate the wire with shrink tubing.

adheres the tape to the surface.To do this, remove the protective coating from the adhesive side and attached to the base.

remains connected to the power supply.And there are some nuances here:

1. If the power supply for LED strip is not too large, you can use it without any problems and hide in the design to be seen.

2. If we use powerful tape of great length, for example, 10 meters, power supply it needs 100 watts.It is very heavy, it can not be hidden in the false ceiling.It is therefore advisable to use two smaller capacity for the two bands.

scheme: Parallel connection of two tapes to a single adapter

3. If the length of the tape is large (10 m), with the power supply unit is not too large, you can connect two tapes simultaneously.Such a method has several advantages.The fact is that when a current is passed through the tape length of 10 m, the first LED will always be too cool, and the last - on the contrary - a little warm, and faint light, respectively.To avoid this, it is advisable to be connected in parallel to the power supply.

to connect color LED strip is required to use the controller.It allows you to change the color, brightness and implements synchronous opening and closing of the LEDs.

controller has two terminals: the first - to connect to the power supply, and the second - for the color channels and the common wire.Connect power supply wires to the controller, and then connect to the last tape.

If you connect two colored ribbons in parallel, you need to purchase a more powerful power supply and controller.Unfortunately, their weight is also too large to mount them in the ceiling.

### Installing LED lamp ↑

Installation of LED lamp does not require any special knowledge and action.Almost all LED lamps are made with standard socket, which greatly facilitates the selection of the lamp.

These lamps can be mounted to any surface.In any case, as stated by the manufacturer.Consider the option to install the lamp in plasterboard partitions.

Choosing a location for installation.Drill a hole is drilled.Take the lamp, his wires stretch into the hole, slightly dent the device to lock.

put in the necessary light bulb.The connectors are connected to the distribution block and connect the power.

## versatility and variability of application ↑

### Lighting LED ribbon ↑

LED strips can be illuminated ceilings and other structures in the room

LED tape is not used as the main lighting in the apartment, yet their power is not high enough.But illuminate the work surface in the kitchen, identify key places in the interior, decorative niches or decorate multilevel ceilings - a problem not just for LED strips.Due to the flexibility, they can be laid on the curved surfaces of almost any configuration.

### LED lighting ceiling ↑

for ceiling lighting You can use the LED strip lights and

to illuminate the ceiling can be used as tapes and LED lamps.The only difference is that the tape can provide a decorative function, and lighting can significantly lighten the room, or even serve as the main source of light.

tapes glued to the ceiling recess so that they could not be seen with the naked eye, and directed upwards to illuminate the ceiling surface.Fixtures often mounted in plasterboard false ceilings or constructions like Armstrong and sent down into the space of the room.

### the backlight rooms ↑

for head room lighting can also be used LED equipment

for room lighting using LED lamps with 5 to 12 watts of power.How to calculate the required number of luminaires and the luminous flux of each already described above.Thus there are lamps which are designed to replace the older incandescent bulbs.Lamps can be installed in chandeliers, sconces, and in the body of furniture.

### LED lighting in the kitchen ↑

LED lighting in the kitchen: highlighting cabinets outside and inside, as well as the ceiling

With the help of LED equipment can illuminate the work area in the kitchen and the place where most people are.You can use lighting, built-in ceilings.And to highlight the kitchen cabinets can be used LED tape adhered to the surface.If the lighting is thought out at the design stage, if desired, you can order directly in kitchen with seating for lamps.Furthermore, the cabinets can be illuminated from the inside.For example, make sure that the backlight is switched on only when the door is opened and turns off when closed.

### LEDs in emergency systems ↑

LED equipment is used in an emergency and emergency lighting

Disaster or emergency lighting is designed to illuminate the premises, buildings, vehicles, if there is a sudden power grid.In this case, it is powered by the generator.Power LED lighting is so small that it can significantly save the budget of the municipal enterprises that require room emergency lighting.

### Industrial LED Lighting ↑

Industrial LED lighting used by businesses, parking lots, highways and other places

use of LED equipment in commercial and industrial buildings not only save on electricity consumption, but provides numerous amenities.Firstly, if fails incandescent, for its dismantling or installation is necessary to cause the new professionals and technicians, as they are on the inaccessible heights.If the LED lamps are used, and their service life is not less than 5 years, the need for replacement is extremely rare.In addition to the facilities such lamps are used to illuminate the quays, car parks, cottage villages, highways and roads.

LED lighting is gaining momentum.It has a lot of advantages: efficiency, environmental friendliness, convenient range of radiation, long life, light is visible in the far distance, and, of course, design.In addition, replacement and installation of LED lighting is very simple, it can be done independently, without the help of professionals.
