The usual bulbs have a spiral, which, hot, begins to glow. Energy -saving LED lamps of the latest generation work on a different principle. It is worthwhile to figure out how they differ, how to choose them and whether it is worth buying them to replace lighting equipment.
What are LED lamps?
The main source of light in energy -saving devices is miniature bulbs – LEDs. These semiconductor elements convert current into light radiation. LED lamps are distinguished by a long service life, but have a number of disadvantages that should be known when choosing light bulbs. The power supply for diodes is installed individually in each lamp, it converts a voltage of 220 V into ordinary sockets into a small one, which is necessary for the operation of lamps in 6/12 V.
The device of the LED lamp
In each case, up to several dozen bulbs are installed, their number can vary and depends on the power of the device. LED-lamp basements have standard sizes, which allows you to use them in any lamps and not resort to changes in electrical wiring. The design is simple and includes the following elements:
- Discharger or reflector, which has the appearance of a mirror hemisphere and is necessary to increase the angle of light flow.
- A set of LEDs, the number of which in different lamps changes from several pieces to several tens.
- An aluminum alloy printed circuit board, which provides effective heat separation.
- A radiator that performs the function of maintaining the operating temperature inside the device.
- Capacitors that eliminate pulsation on LEDs.
- The driver for stabilizing the voltage inside the device.
- A polymer coating that reaches a base and is a protection against electric trays.
- A base for screwing the lamp into the cartridge.
Pros and cons of the LED lamp
Replacing light sources in apartments and offices occurs everywhere. The advantages of LEDs include:
Low energy consumption, which compared to other lamps makes ceiling LED lamps with a profitable acquisition. The long service life is distinguished by LED lamps from analogues, they break in the case of poor -quality assembly. The repair of the device is possible, this quality is an important advantage that distinguishes LED lamps from others. Their disadvantages can be considered:
- high cost;
- Heat release with poor -quality operation of the radiator in the lamp;
- Not always comfortable color temperature.
Which is better – LED or energy -saving lamp?
When such a question arises, then energy -saving usually means fluorescent lamps. They also have a long service life and consume a minimum amount of energy. At the same time, they have significant drawbacks in comparison with LED high -quality lamps: flicker, which negatively affects vision, the complexity of disposal, potential harm to health and heating the body.
Types of LED lamps
Such lighting devices have a clear classification, and it is easy to divide them by type. Depending on the type of use, they are street and home, automobile and industrial. By type of design, LED LED lamps are divided into overall use options, directed light and spots-linear models for lighting trading halls and offices. Depending on the type of basement, the new generation LED lamps are divided into two types: low -voltage and high -voltage. By type of body, the products are divided into:
- Pointed;
- Flights;
- ribbons;
- Panels.
How to choose a LED lamp?
Calculate home lighting parameters for any master. The exact amount and power of LED lamps must correspond to the area of the room. Lux is a measure indicating the amount of lighting of 1 m². Depending on the type of room, the number of LC may vary. When calculating the final value, it is worth folding the brightness of all bulbs in the chandelier. There are mobile applications for determining the brightness of light in the room, for example, Sensor Sense. The approximate value of the luxury for different rooms corresponds to the parameters:
- in the bedroom – 100 lux;
- in the hallway – from 50 to 100 lux;
- in the dining room and living room – from 100 to 200 lux;
- in the bathroom – from 50 to 200 lux;
- In the office – 300 lux.

Color temperature of the LED lamp
Experts call the color temperature an important characteristic. The level of comfort in the room where lighting is installed depends on this parameter, which LED lamps are better for a house with a warm or cold glow, it is necessary to solve it yourself. Light sources are divided into three groups: warm, day and cold. The color temperature affects a person: a warm glow relaxes and is suitable for the bedroom, and the cold tones, the LED lamps of this type are advised to install in the working areas.
Forms of LED lamps
Light bulbs of various shapes can be found in the LED product market. Options for installation in standard chandeliers and sconces are equipped with basins E14 and E27. LED spotlights for installation in suspended and suspended ceilings have pin connectors. Such a base is marked with the letter G with numbers, which indicate the diameter or distance between the pins. There are several forms:
- “Pear” – One of the most famous forms of LED home lamps. Such light sources are similar to the well -known incandescent lamps that were used in the USSR. Pointed LEDs in them differ in a glow angle of 180 °.
- Form “candle” Suitable for decorating an interior in retro style. A wide angle of dispersion allows you to screw such lamps with a cartridge down. Such compact lamps in nightlines, candelabrah look good. Their power is not very large.
- LED lamps “corn” They are called so due to the similarity with the cobs of the well -known grain culture. On the device of a cylindrical shape in rows are point light bulbs. Due to the multidirection of the diodes, the angle of dispersion of light in such lamps is 300 °.
Rating of LED lamps
Modern technologies do not stand still. Manufacturers try to surprise buyers and produce new types of lamps, “smart bulbs” have already appeared on the market, connected through the Wi-Fi network and controlled remotely using a special program. By answering the question of which LED lamps are the highest quality, you can choose the perfect product to arrange your home.
- The German company OSRAM is known far beyond its country and is famous for quality products in the lighting market.
- Philips is known in the electrical goods market and provides a wide range. The table is a desktop LED from this company can be a profitable purchase. Forms, color temperature, options for cartridges are presented in a wide range.
- The European level of quality supports GAUSS products. Soft light without flicker, a variety of shapes and sizes favorably distinguishes the LED lamps of this manufacturer. The proprietary packaging of goods is the business card of the company.
How to connect a LED lamp?
The LED lamps replaced the fluorescent and fell in love with their positive characteristics. Replacing ceiling LED lamps that failed is made in a matter of minutes, for this it is not necessary to have an electrician diploma.
- First, the voltage on the network is turned off.
- It is necessary to make sure that the light bulb is designed for a voltage of 220 V.
- After making sure that the base size in the cartridge corresponds to the parameters of the lamp, you can start screw it.
- When installing LED lamps in the stretch ceiling, special thermal rings are used, which prevent the heat of the ceiling coating tissue.
- After the work is completed, the voltage in the room is included.

Why does the LED lamp blink?
The flickering of LED lamps is an unpleasant feature that can irritate the eyes of a person. There may be several reasons for such a phenomenon. It is necessary to understand why the LED lamp blinks, in order to eliminate the problem in time and maintain health.
- Cheap LED lamps are equipped with inexpensive details that cannot cope with the effects of the electric circuit.
- When the light is turned off, the flickering of the lamp indicates the wiring malfunction. In this case, it is worth checking where the phase is connected in the camshaft. It is considered correct if the phase wire is connected to some contact of the circuit breaker, and not directly with the lamp.
- Low voltage is the cause of flickering the lamp turned on. A way out of this situation may be the installation of a stabilizer that will maintain the same voltage on the network.
Why does the LED lamp light after turning off?
Many owners noticed that LED bulbs continue to glow after turning off. This is not dangerous for people, but reduces the service life of LED lamps. There may be several reasons for this phenomenon.
- The backlight switch to which the lamp is connected contributes to its combustion after the circuit opens. The switch should be replaced with another model.
- Features of the design that are manifested in inexpensive models. LED LED lamp should be replaced with a quality model in this case.
- Problems with wiring are the most unpleasant reason that may require opening the walls and replacement of wires.
How to disassemble the LED lamp?
Modern devices are simple, they do not require special dishes for disassembly. Repair of LED lamps will be able to make a home master who has a minimum set of tools. A knife, screwdriver and any available indicator – everything that is necessary for disassembly.
- Remove the diffuser by inserting the knife blade between the plastic lamp housing and glass.
- Determine the serviceability of the fuse by “calling” it with a measuring device. If the fuse is faulty, it needs to be replaced.
- The details on the board should be carefully inspected, the swollen capacitors should be replaced by good.
- For further disassembly of the bulb, it is necessary to remove the board by unscrewing the fastening bolts.
- Pulling the upper part of the lamp, it must be removed, and check the contacts that connect the base to the board. If necessary, the contacts of contacts are carried out.
