LED sources cope with the functions of accent, functional and background light. Small lighting elements are used in groups, which allows dimmability. The advantages of LEDs are low power consumption, low heating and high luminous efficiency. They can perform additional functions: setting colors, delayed or smooth shutdown, wireless speaker, light alarm.
Chandelier selection
Lighting is a useful tool for designers and decorators. LED chandeliers do an excellent job of creating an atmosphere and situational zoning of a room. The lamps are decorated with brass, bronze, stainless steel, chrome, nickel and silver plating, crystal, crystals, porcelain. The choice of a chandelier is based on the permissible dimensions, area and the required lighting power: living room and kitchen - 200 lux, nursery and bedroom - 150 lux, hallways and bathrooms - 100 lux. For the sake of your own safety, you should pay attention to the documentation. The seller must provide a quality certificate, a sanitary permit describing the materials used, a warranty card.
Ceiling lamps are distinguished by the type of attachment:
- built-in (in a drywall box, under stretch ceilings) - a hole is mounted according to the parameters;
- overhead - small lamps of simple shapes or volumetric chandeliers of the most intricate designs;
- suspended - more suitable for halls and halls with ceilings above 2.7 m, less popular in residential buildings.
The type of appliance can be matched to the space in any style. There are carob (supplemented with lampshades and shades) and hornless models.
Light can only be supplied with LED lamps or halogen lamps with LED backlighting.
Fixing the fixture
The usual fixtures are equipped with hooks. Modern options are equipped with a mounting plate. Lots of wires and plastic boxes can be confusing. To understand which side to approach the chandelier, you need to understand its design features.
Recessed spotlights are easy to install. The diameter of the illuminator body determines the size of the hole (usually 68 mm). The outer skirt is slightly wider to secure the outside of the appliance. Inside, this task is performed by special springs. Average step 1 m.
The location of the chandelier on the ceiling is included in the design project or is chosen independently. The body of a new electrical appliance can close an old hole, including.
- The perforated strip is fixed to the ceiling.
- Before connecting the LED chandelier, the power on the panel is turned off. Wiring can only be done in a de-energized system.
- It is easy to understand the conductors by the color marking of the insulation: yellow-green - ground, blue - neutral, other colors - phase. If for some reason this cannot be done, a tester will come to the rescue. An extra phase wire may come from the old double switch, which is removed and isolated. The communicator is replaced with a one-key or touchscreen. The controller with the receiver is located in the upper bowl of the chandelier. For LED sources, the power must come through an electronic or induction step-down transformer.Lead wires enter the terminal block according to the designations: L - phase, N - zero, PE - protective earth.
- On a chandelier unit with a control panel, the wiring connection for groups of lighting fixtures is shown in the diagram. If not, you need to find it in the manufacturer's instructions. If desired, the distribution can be changed, altered for yourself.
- All decorative elements are collected, lamps are installed, lampshade is fixed.
After checking the correctness of the assembly, turn on the power and check the operation of the chandelier.
Selection of the control panel (CP)
The presence of a remote control saves when, in order to output the switch, you need to gouge walls or spoil their appearance with cable boxes. Although a conventional switch is often left to supply power. Only after turning it on will it be possible to use the remote control. PU can be supplied with a chandelier, but universal wireless adjustment panels are produced that can be connected to any lamp or control several devices at once. The lighting in the apartment is combined with the "smart home" system.
The controller with the antenna is placed in the housing of the lighting device, in the cavity of the ceiling near the suspension, or in the back box. Power is supplied from a 220 V network. The stationary remote control is mounted on the wall and is equipped with a sound search for the remote controller.
Wireless equipment can operate on different types of signal:
- infrared - the most budgetary option, works at short distances up to 8 m, only with line of sight;
- radio - the most widespread, can work through partitions at distances of up to 30-100 m;
- Wi-Fi - has the widest possibilities, including control from a mobile device, the range is expanded to 300 m.
The number of control channels depends on the number of luminaires and ranges from 1 to 4. Typical scheme: buttons A, B control modes, C - full switching on, D - complete shutdown. The total switching power of the lamps is 1 kW. LED sources are controlled via a 0.2 kW channel.
To avoid interference in radio transmitters, the sensor and receiver are tuned to the same frequency. For the operation of the mobile part of the equipment, it is sufficient to supply power from rechargeable batteries or replaceable AA, AAA batteries.
Weaknesses of the device
There are many advantages to LED luminaires with remote control, but malfunctions still happen. Some problems have explainable reasons.
If the power line from which the chandelier is powered is two-core, the risk of burnout of the device increases.
Conclusion of a large amount of electronics in the chandelier body provokes overheating. The technique does not stand up, it breaks down. This is especially true for budget Chinese models. It is necessary to carefully monitor the incoming voltage and continuous running time.
Common malfunctions:
- The chandelier does not respond to commands or turns off spontaneously. Circumstances do not change after replacing the batteries - you need to check the buttons using the phone's camera, which will show the beam when pressed. If found, you can clean the contacts or change the remote control completely. If the buttons are okay, the problem is most likely a wireless switch malfunction. The device circuit contains a metal-film capacitor designed to extinguish overvoltage. After 1–1.5 years of operation, its capacity drops, the voltage drops to 6–7 V, the electromagnetic relay stops closing, and the microcircuit does not work correctly. The problem is solved by replacing the capacitor. It is better to opt for an expensive imported model.
- When the chandelier moves, the light bulbs can glow with weak contact with the power cable. In this case, check the wiring assemblies.
- The group of lamps does not function. If one LED fails, the entire tape stops working. You can try to find and replace a non-working item or buy a new tape. The cause could be a transformer. If the multimeter at the terminals showed no voltage, the part is changed.
- Failure of the luminaire to work is a reason to check the voltage of a suitable cable with a voltmeter, eliminate a short circuit between phase and zero, check the integrity of the lamps.
- Noticeable flashing or turning off of lamps when adjusting the lighting. Standard dimmers are not suitable for adjusting the brightness of LED sources; connecting an LED chandelier requires special equipment based on pulse width modulation (PWM).
The remote control chandelier combines background light, night light and disco ball. In this case, you can change modes while sitting on the couch, sometimes even in another room. The new generation of lamps is finding more and more fans.
