This article examines in detail the features of such lighting devices as LED ceiling chandeliers for the home: the classification of structures and features of lamps installed in them, the advantages and disadvantages, the principle of operation and the distinctive features from other products of similar purpose. In the text you can find a photo-catalog of interesting ideas and tips on choosing chandeliers for the kitchen, bedroom and living rooms for other purposes.
LED Ceiling Light for Home: general design features
Chandeliers with LEDs have become a real breakthrough in the field of lighting technology. The ceiling version of the devices has found wide application in administrative and office premises, and then in the living rooms of private houses and apartments. Thanks to their improved performance, LEDs are gradually replacing energy-saving options and incandescent bulbs from the market.
Compared to conventional incandescent bulbs, LEDs are much safer. During operation, they do not harm human health, their disposal does not cause difficulties and does not have a detrimental effect on the environment. The design of the LEDs does not contain gas or mercury, as in gas-discharge lamps. They differ from conventional products in dimensional parameters and the type of luminous flux, which in this case is directional.
Consumers among the advantages point out the high reliability of LED chandeliers, customer reviews from the forums confirm the practicality of these devices:
“It takes just a second to launch the ceiling light. The lamp instantly gives out a powerful stream of light. Such advantages are not characteristic of energy-saving lamps, which require much more time to start up. As a decorator, I can not fail to note the possibility of choosing different shades of light and colors. LEDs have extensive design capabilities. ”
Oksana Shcheglova, St. Petersburg
“Since using LED devices, my electricity costs have decreased significantly. After reviewing the information on the network, I personally checked the efficiency of these lamps. Moreover, this does not affect the power at all, the room illumination level is acceptable. ”
Victor Smyatko, Moscow
Note! Compared with luminescent options, LEDs are 50% more economical. Using them instead of incandescent bulbs can reduce costs by 95%.
The basis of the operation of ceiling chandeliers is a conventional converter. At the output, this element produces a voltage of about 5 volts. The converter can have a different type of design, which uses a capacitor and a diode or works in accordance with the bridge circuit.
To prevent the appearance of impulse noise during operation, an additional capacitor and a resistor are included in the converter circuit. These elements are designed to dampen pulsation. And the main capacitor smoothes the voltage spikes at the output.
Such a device for LED lamps for chandeliers, as well as the absence of a need for a transformer, has allowed manufacturers to reduce the dimensions of lighting fixtures, to make them light and attractive. In addition, the scheme may include additional devices designed to suppress interference. These elements include the varistor and inductance coil. The first component provides protection against impulse noise and static electricity, and the second – simplifies the design, by reducing the number of necessary elements.
Manufacturers offer several schemes, according to which the lamps are arranged. All of them have their own advantages. For example, lamps consisting of a damping resistor and diodes are distinguished by a long service life, and the presence of a double connection eliminates flickering in LED elements, due to which human eyes do not get tired of light.
LED devices that are on sale, differ in technical characteristics. Looking for where to buy a chandelier for the room, it is worth to identify for yourself the most important parameters. First of all, the type of luminous flux and its strength is considered. This indicator reflects how effective the lighting in the room will be when using a particular device. In order for the buyer to visualize the brightness of the light, manufacturers additionally indicate the equivalent of power for an incandescent lamp.
Another important technical indicator is power consumption. Devices equipped with LED lamps, consume about 1-10 watts.
Note! Power consumption indicates the amount of electricity needed to operate the device. However, this parameter cannot determine the quality of the glow.
In the catalogs of chandeliers found devices with different color transmission. For home luminaires, the optimal ratio is 70 or more. Quality manufacturers must place data on this characteristic on the packaging of the device.
Luminaire classification by temperature:
|Glow Temperature, Kelvin||Type of lighting|
|2700-3500||yellowish (comfortable option for the eyes)|
|6500 and more||cold (not applicable to residential premises)|
LED lamps have a long service life. However, over time, the amount of emitted light decreases. Standard norms indicate that as a result of 25,000 hours of operation, primary capabilities are reduced by 30%. For this reason, this parameter is considered as the officially accepted lifetime of LED lamps.
According to the type of design and parameters of the luminous flux, the following types of lamps are distinguished:
- With directional light.
Linear designs are used in office premises. Lamps of this type, installed in chandeliers, are made in the form of a tube, equipped with a rotary base. This structure allows you to change the angle of the light flux. Universal lamps of general purpose are suitable not only for office space, but also for living rooms in apartments and private houses. They form a diffused stream of light that is as close as possible to natural sunlight and does not irritate the eyes. Most often, this type of lighting is found in the photo of large-sized ceiling chandeliers with remote control.
Lamps with directional light are applied on the following objects:
- exhibition centers;
- the shops;
- shop windows, etc.
Directional lighting gives a special look to the room and draws attention to the things in it. Similar LED chandeliers on the ceiling are purchased as a decorative ornament, for placing accents.
By the design of the base LED lamps are:
- with Edison cap;
- with recessed contacts;
- with focus;
Interesting fact! LEDs are characterized by a long nominal glow. They are able to provide continuous work for 50,000 hours.
LEDs have become an alternative way to replace many types of lighting systems, in particular devices with a large number of lamps. Such designs can be equipped with sound and motion sensors, remote control and other functional add-ons. Ceiling ICE chandeliers have a long service life. The minimum period of effective operation is 10 years. At the same time, the frequency of switching off and switching on the device does not affect the service life.
Lamps are not limited in shape. Due to this, the range of possible design solutions and decorative design of devices is expanding. Designs of round LED ceiling lights and laid-in built-in type are used for the design of ceilings:
- mounted plasterboard;
Other drywall constructions are no exception, for example, partitions, niches, arches, shelves. It is allowed to use round LED chandeliers in rooms with elevated temperatures, since the LED elements are practically not heated. In these lamps there is no flicker. The luminous flux is formed continuously, so the human eyes do not get tired. Since the angle of illumination is adjustable, such devices can be successfully used to create visual effects in the room.
The LED chandelier, if properly connected, can last for a long time. To avoid the difficulties associated with installing or breaking the device, it is advisable to entrust the installation work to a professional electrician. In this case, you can achieve a quality result and keep the warranty.
