Today, one of the most trendy elementsDecorating rooms inside the house is considered a hidden illumination of the ceiling. Its main purpose is to create additional lighting in the end parts of the room. In order for the hidden lighting to meet modern requirements, it is necessary to equip it in accordance with all the rules of accommodation. 
The main function of the light is additional lighting of the room.
The principles of arrangement of hidden illumination on the ceiling
Regardless of the configuration of the ceilings in yourthis type of lighting can be installed in any corner. This is achieved through the flexibility of devices that provide hidden illumination. There are 2 simplest methods of arranging additional lighting:
- illumination of the gypsum cardboard aperture;
- illumination of polystyrene cornice.
The scheme of connection of LED ceiling lighting. With the first method, a gypsum board should be placed at the edges of the entire ceiling area in a repaired room. Inside this box, the backlight is installed in the future. The advantage of mounting this method is the heat resistance of the gypsum board material, that is, it will withstand the impact of any lighting devices. The box is kept under the ceiling much better than polystyrene cornice. In addition, this method allows you to fix the lighting devices directly on the profile. In addition to hiding the backlight, the gypsum board can be used as a lining for other elements of the power grid, which are undesirable for gaze. The disadvantages of this method are the high cost and laboriousness of the installation process. It will require you to have some knowledge in the field of repair and architecture. It is worth considering that it is extremely undesirable to install such a box in the kitchen. Due to high humidity gypsum plasterboard may crack over time. Back to contents</a>
Preparing for the arrangement of the ceiling lighting
Before starting work, you will need to prepare the following tools and accessories:
- electric drill;
- curved screwdriver;
- plane;
- a small saw;
- scissors for cutting metal;
- roulette;
- level;
- self-tapping screws;
- gypsum plasterboard and profile.
Tools for mounting the LED suspension. First of all, you need to choose the type of opening that you want to equip in the room being repaired. In small rooms it is recommended to make the ceiling light in an open aperture. In this case, there will be no need to arrange a curb along its edges, and the distance to the ceiling will be the smallest. A closed aperture means placing a low border hiding lighting fixtures, it will require a 5 cm below. Next, you need to mark the longitudinal line on the wall surface with the orientation to the level. This layout will need to attach a UD profile, which will become the foundation for the backlight opening. After that, you need to mark out the next line for fixing the ceiling, remembering to use the tape measure for accuracy. On the line, drill holes with an interval of 50 cm, insert plastic dowels into them and fix UD profiles with hardware. The use of wood choppers in place of plastic dowels is unacceptable, as they intensively absorb the liquid and swell quickly, which contributes to their loss. 
The scheme of hidden illumination. CD-profiles are used as support racks, so they need to be cut and fixed using self-tapping screws. Since high pressure will not be applied to the crate to be created, support posts need not be connected to wall profiles. In the process of fixing the gypsum board, you need to monitor the seam between two sheets of material, it should be placed on one profile. To make the plasterboard material uniform and accurate, it is necessary to cut it with a small saw or a hacksaw. In this case, the edges should be trimmed with the help of a plane. At the completion of the arrangement of the box, it is required to properly seal the joints and holes that appeared as a result of screwing in the self-tapping screws. Before the puttying, the joints can be carefully treated with paint tape. Used putty should be plaster. If you paint the box yourself, do not forget to prime it. Next, you need to place and connect the lights. The openings from this material allow placing various lamps and lamps. Modern plasterboard ceilings are usually equipped with LED strip. Its productivity exceeds the simplest lighting devices by a factor of 10, with an efficiency of 22%. It should be borne in mind that such ceilings can withstand only a small weight. Lighting devices should have a mass of not more than 10 kg, otherwise they may fail. Back to contents</a>
Arrangement of polystyrene cornice lighting on the ceiling
Ceiling of gypsum cardboard with illumination. As a rule, such work requires special tools and equipment, so often they are carried out by a qualified construction team. At the same stretch ceilings can be created from a polystyrene cornice, which will simplify the process of arrangement. Such a ceiling can be created with your own hands. Polystyrene cornice has a lower margin of safety compared to drywall material, and it is less heat-resistant. This means that the cornice can be equipped with only an LED strip, other lighting devices will spoil its surface. Its main advantages are simplicity of arrangement and low cost. Installation of polystyrene cornice can be completed in just 3-4 hours of operation. Back to contents</a> How to arrange hidden lighting in polystyrenecornice yourself First of all you need to make a marking at a distance of 5-10 cm from the ceiling. This longitudinal line will be used to glue the polystyrene cornice. In case of uneven ceilings, it is recommended to do marking with parallel orientation, since the line drawn with the help of the level can go crookedly. After the completion of the marking, it is necessary to process the places for gluing the cornice. It is recommended to thoroughly clean the surface of plaster and wallpaper glue, and then primed it with a primer. There is a variant of gluing the cornice without coating treatment, but in this case it will be necessary to purchase a structure with a large area of connection. 
Minimum dimensions of the niche under the backlight. After that, we glue the surface to be treated with glue and press the cornice well, holding it in this position for a few seconds before moving on to the next one. For a good connection, the following types of glue are recommended:
- liquid Nails;
- acrylic putty;
- Titanium.
All existing seams need to be glued together morecarefully. To strengthen the design, you can use matches that will replace nagels. Particular attention should be paid to the end sections, since the polystyrene cornice most often hangs in these places. To exclude this possibility, it is recommended to buy special places in the building store. After the installation and reinforcement of the eaves are completed, it is necessary to put electrical wiring into it and equip the power supply unit, which will supply current to the LED strip. It is recommended to strengthen the unit on the wall, because it is very hot and weighs a lot. In order to secure it securely, it is necessary to use collars based on capron. When connecting an LED strip, you need to pay attention to the labeling of the wiring. It should be noted that tapes longer than 5 m should be connected to the network in parallel. In the case of serial connection, there is a possibility of burning tracks. To create a hidden backlight, it's enough to buy a tape with 40-60 LEDs. With more quantity you will get an alternative light source. When connecting cables, do not leave uninsulated sections, otherwise they can come into contact with the hardware and cause a short circuit. Standard tapes have a voltage of 12 V, select the appropriate power supply for them.
