A sober calculation - the basis for success

Selection of the power supply for LED strip

LED tapes are available in rolls in length of 5 meters,Each meter may 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 places possible cutting designated by the manufacturer.

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

Here is an example calculation:

We purchased SMD 3528 strip. 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 on the packaging.

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

Consumption tape power: Ptot = Pm * L = 4,8 W / m * 7 m = 33.6 W;


Ptot - the total power consumption of the entire tape;

Pm - input power of one meter tape;

L - length of the tape.

Total Tape A general power consumption of 33.6 watts. But to ensure the proper operation of the power supply must be made 20% power reserve.

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


P - the required power supply unit;

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

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

Calculating the number of LED lamps

Calculating the number of LED lamps

The LED lamp can be used in false ceilings

LEDs have ceased to apply only as decorative lighting. New super-power LED technology allows to use them as the brain lighting in a house or apartment and even in manufacturing.

LED lighting calculation in this casemade in view of building codes, SanPiN and other regulatory documents to ensure comfortable conditions, livelihoods or workflow in the room.

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

If exact data are not needed, you can trydo the calculations yourself - semi skilled manner. First, determine what we want to highlight, rather than any existing lamps will use LED. For each task will require different lights: whether floor lights, head lights in the room, light furniture or ceiling.

For the calculations, we need only one parameter- light flow. This kind of brightness, intensity of light, 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 approximately 1200 - 1300 lm. For example, to replace the light bulb in the toilet at 60 watts will need to find the LED lamp with a light output of 600 - 700 lm.

If not enough information on the package,You can perform calculations, based on the power of the lamp. Most often, LED lamps consume from 5 watts to 12 watts. In this exemplary light output of 1 W 50 - 80 lm. There may be more, but we will take in a minimum - 50. For the lighting of the room 18 m2 must be 2500 lumens. Divide by the smallest possible luminous flux of 50 lm at 1 watt. Get 50 watts. That this should be the total power of LED lighting in the room. But how to choose the 10 fixtures at 5 watts each, dispersed evenly throughout the room, or 4 high-power lamp 12 Watt - you decide.

LED lighting design

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

Mount your own hands

Installation and connection of LED strip

We determine how long the site want to highlightribbon. If it is more than 5 m, re-buy the necessary amount of tape and cut off the missing segment. With one power supply unit can be used a maximum of 15 m tape (cassette 3).

Then solder the 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 wire with shrink tubing.

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

You're connected to the power supply. And here there are some nuances:

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

How to connect two powerful LED strip to the two power supply units Diagram: Connecting two LED strips with two power supply units

2. If we use a powerful tape of great length, eg, 10 m, power supply it needs 100 watts. It is very difficult, it is impossible to hide in the false ceiling. It is therefore advisable to use two smaller power unit for the two bands.

Connecting the two tapes to a single adapter in a parallel fashion

Driving: Parallel connection of two tapes to a single adapter

3. If a large belt length (10 m), the power supply unit is not too large, it is possible to connect two belts in parallel. Such a method has several advantages. The fact is that by passing the current through the tape length of 10 m, the first LED will always be too cool, and the last - on the contrary - a little warm up and thus faint light. To avoid this, it is advisable to be connected in parallel to the power supply.

How to connect color LED strip

Diagram: Connecting the RBG color LED strip through the controller

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.

The controller has two terminals: First - for connection to the power supply, and the second - for the color channels and the common wire. We connect the 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 a false ceiling.

Installing LED lamp

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

Such lamps may be mounted to any surface. In any case, as stated by the manufacturer. Consider the option to install the lamp in the partition of the drywall.

Choosing a location for installation. Drill a hole is drilled. Take the lamp, its wires are extending into the opening, slightly dent the device to lock.

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

The versatility and variety of application

Lighting LED Strip

LED Strip Light

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

LED ribbon not yet used asthe main lighting in the apartment, yet their power is not large enough. But illuminate the work surface in the kitchen, to 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 ceiling lighting

LED Lighting Ceiling

For illumination of the ceiling, you can use lights and LED strip

To illuminate the ceiling can be used astape, and LED lighting. The only difference is that the tape will be able to provide only a decorative function, and lighting can significantly lighten the room, or even be the main source of light.

Tapes glued to the ceiling recessso that they are invisible to the naked eye, and directed upwards to illuminate the ceiling surface. Lighting often mounted in plasterboard false ceilings or constructions such as Armstrong and directed down into the space of the room.

Options for lighting the room

Lighting of the room with the help of LED equipment

can also be used for the head of the room lighting LED equipment

For room lighting using LEDlamps with 5 to 12 watts. How to calculate the required number of luminaires and the luminous flux of each already described above. At the same time, there are lamps that are designed to replace the old incandescent lamps. The luminaires can be installed in chandeliers, sconces, and in the furniture body.

LED lighting in the kitchen

LED lighting kitchen equipment

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

With the help of LED equipment can beto illuminate the work area in the kitchen and places where people are more often. You can use lamps, built-in suspended ceilings. And for lighting kitchen cabinets, you can use the LED tape adhered to the surface. If the lighting is thought out at the design stage, if desired, you can immediately order the kitchen set with places for fixtures. Moreover, 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 off when you close.

LEDs in emergency systems

Emergency LED lighting

LED equipment used in emergency and emergency lighting

Disaster or emergency lighting is designedilluminate the premises, buildings, vehicles, if there is a sudden cut-off grid. In this case, it is powered by the generator. Power LED lighting is so low that allows to save enterprises municipal budget, which require room emergency lighting.

Industrial LED Lighting

LED Lighting Industry

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

Using LED Equipmentindustrial and commercial premises can not only save on electricity consumption, but provides numerous amenities. Firstly, if fails an incandescent lamp, for its dismantling or installation of new accounts to call professionals and technicians, as they are on the inaccessible heights. If the use of LED lamps, and their service life is not less than 5 years, the need for replacement is extremely rare. In addition to facilities such lamps are used to illuminate the quays, parking lots, residential estates, motorways and roads.

LED lighting is gaining momentum. It has many advantages: efficiency, environmental friendliness, easy radiation spectrum, durability, light is visible at a great 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.
