Modern indoor design is often helped by the installation of LED recessed downlights . They are semiconductor devices having an electron-hole transition, with the help of which optical radiation is formed when an electric current passes along a direct path. A feature of the technology lies in a narrow range of the light spectrum, due to which it is possible to obtain the desired color at the output.
Triumphal appearance
Today, the LED recessed downlight is no longer a wonder. He began to appear more often in residential buildings and apartments. The quality of LED lighting has improved markedly. And it all started in 1907, when a British scientist was able to describe the electroluminescence seen when passing current through a metal element and silicon carbide.
Repeated experiments were carried out in one of the Russian laboratories 15-16 years later, but then they were not given much importance. The first LED, which has practical applications, was created only in 1962. The invention of the blue semiconductor element, in combination with green and red analogs, made it possible to obtain white light with a high level of energy efficiency. After that, they began to actively produce LED ceiling lights, which are built into suspended and suspended structures.
Features of devices and scope of operation
Each product is a set of semiconductor LEDs assembled in a housing made of metal or plastic. Built-in appliances can be used as a basic source of illumination, a specific decorative element or auxiliary element.
Most often, LED ceiling lights, built into various designs, are used specifically for zoning rooms. If we talk about aesthetic functions, then many models allow you to create interesting effects that improve the perception of space. With the device of general lighting, devices are installed in whole groups.
Most models can be mounted in rooms with different levels of humidity. Their housing is waterproof and resistant to condensation.
What are the pros and cons to highlight?
The high popularity of LED ceiling lights, which can be built directly into a special design, is associated with their many advantages.
- When functioning for 10 hours a day, the elements can last up to 25 years without replacement. During this time, the light flux practically does not decrease.
- Devices are durable and resistant to various vibrations, therefore, even when operating in aggressive conditions, they rarely fail.
- The operating mode of using devices is very wide. They can be installed at temperatures from -50 to 60 degrees. Thus, products can be built into the ceiling not only of a heated room, but also of an open veranda or porch.
- Easy installation makes it possible to save on the invitation of professional workers. The installation technology does not have any intricate subtleties, special equipment is not required.
- The efficiency of the devices is quite high. It can not be compared with the indicator of ordinary lamps.
As for the negative points, they are practically nonexistent. The only significant drawback can be considered somewhat overpriced, when compared with conventional analogues. However, during the operation of lighting devices, this is more than justified.
Element design
The devices in question are classified as LED recessed luminaires. LED ceiling fixtures usually consist of several elements. These include:
- plastic or metal case;
- main cartridge;
- shade or glass to protect the lighting part;
- spring clips for mounting.
As decorations, stained glass, wooden or crystal elements, as well as many other materials can be used. The shape of the case can be not only round, square or oval. Often there are configurations of a specific nature.
Voltage used
The least widely used are ceiling recessed LED lamps of 220 volts. More popular are low-voltage products, which is explained by the demand for compact lamps for use in residential premises and offices. In addition, such devices are safer during operation.
12 and 24 volt models are ideal for wet rooms. They can be installed in bathrooms without much concern. This does not mean that LED 220 volt recessed downlights cannot be used in such conditions. It is just necessary to pay special attention to the choice. It is best to use products with a high degree of protection against moisture.
For models with low voltage will have to additionally install a special power supply. Its power will depend on the number of mounted devices and their parameters. Adapters differ not only in the amount of developed energy, but also in the level of protection against moisture. They may have a sealed or perforated housing. The acquisition is based on the operational characteristics of the premises.
Types of Lighting
LED devices for installation in the ceiling can be of two types.
- Fixed. This category includes products that, after installation, shine only in one direction. There is no movable reinforcement in this embodiment. However, fixed analogues have good design capabilities. They can have an intricate shape and specific decor elements.
- Rotary. Devices have a movable fixture that allows you to direct the light flux in the desired direction. Products provide an opportunity to focus on various interior details. Often with their help mirrors, tables in the dining area or office, sinks and other important places are highlighted.
Despite the specific features of LED pendant lights, they are not recommended for use in bathrooms and other areas with high humidity. In the presence of a movable part, it is very difficult to provide high-quality sealing. As for fixed devices, they are universal, as they can be operated in completely different conditions.
Good layout options
For the main lighting device in the home, it is necessary to place spotlights at a distance of 30 to 40 cm from each other. In this case, there should be a slight indentation from the walls. As a rule, it is 20 cm. As a result, for every 1.5 square meters. m should install one lighting device with a capacity of 20-30 watts. When combined with a chandelier, the number or power of the elements can be reduced.
If square LED recessed luminaires with large dimensions are used, it is best to place them over certain areas. When lighting spacious rooms, the main task is the correct distribution of sources. All functional areas should be clearly marked.
To visually expand the elongated room, you should install a whole group of devices directly along the central part and on both sides. The scattered soft light should be evenly distributed throughout the space. When creating lighting, shadows should be avoided.
With low ceilings, models with a swivel mechanism are ideal for directing the beams up. If the walls are low, then the chandelier will have to be abandoned. Instead, it is better to install a LED recessed downlight 600x600 mm. He will not clutter up space.
Installation tool
The installation process does not require any special skills and knowledge from the wizard. However, to carry out the work, you need an uncomplicated set of tools:
- flat screwdriver;
- a knife for stripping cables;
- nippers;
- drill with crowns for cutting holes;
- pliers.
For convenient access to the devices, you will have to prepare a stepladder or build a structure for moving.
Embedded Technology
Unlike overhead LED-downlights, recessed analogs cut directly into the design of a suspended or suspended type. Work takes place in the following order.
- Marking is applied to the ceiling surface with the exact location of the lighting elements.
- Using a drill with a suitable diameter crown, holes are cut out. If the device has a square shape, then an electric jigsaw is used.
- Through the holes made, the cable is output. A lamp is connected to it through the terminals.
- The lighting element is inserted into the made opening and fastened with special springs.
- A lamp is screwed into the installed housing, after which a decorative trim is put on.
- At the final stage, the lighting system is tested.
When attaching the ears of the springs are reduced so that it is possible to push the element into the cut hole. After being introduced into the suspension structure, they rest on the inner surface. This method of fixation makes it possible to quickly carry out installation work. To remove the device, just grab the base and pull it down.
Prior to the installation of the elements, a wiring diagram must be carefully developed. You will have to take into account the places and methods of connecting cables to each other.
Major manufacturers
The market for LED ceiling fixtures is represented by many brands that differ in technical and quality characteristics. Choosing the right lamp was not easy. So that consumers can navigate the diversity of brands, it is necessary to consider the most popular of them.
Mark | The country |
GLOBO | Austria |
Massive | Belgium |
Mantra | Spain |
Lightstar | Italy |
NOVOTECH | Hungary |
Consumers leave many positive reviews about GLOBO products. They note the stylish design and high quality characteristics of the devices. During operation, problems with models of the Austrian manufacturer usually do not arise. Other brands are inferior to the above brand in terms of reviews, but the percentage of positive comments is about the same.
In conclusion
For the decorative design of multi-level pendant-type structures, experts propose using LED ceiling lights built-in 3WT. They are economical in operation and allow you to achieve interesting aesthetic effects. Their cost is low, so there is no tangible impact on the budget. For little money, you can get an attractive lighting design.
