What functions are performed by modern dimmers for LED lamps 220
The first devices in this category are designed for a step change in brightness. Later, there were more sophisticated dimmers, continuously adjustable. They are equipped with special steel blocks to perform extended functions:
- Embedded and remote sensors (sound, light, movement) allow to arrange the supply voltage on cotton, other control action.
- Soft ON / OFF mode is not only pleasing to the user. It reduces the load on the network, and prevents premature failure of the light sources themselves.
- Connecting to a modern management system and alarm perform remote control and works on user-specified program.
Note! The modern trend - a gradual reduction in price of electronics. This means that the multi-function dimmer for LED strips (tubes) can be purchased inexpensively. However, one must keep in mind the standard rules specific reliability degradation with increasing design complexity.
The principle of operation of the dimmer, features different designs
This figure shows the qualitative features of the dimmer for LED bulbs 220 V. Note the double protection against voltage surges, which prevents damage to the electronic circuitry. In practice, useful silver plating potentiometer that provides a reliable electrical contact over a long service life. Many ordinary consumers given enough options to choose the best product on the shelf in the store.
But a careful person would need more information.
In this circuit, resistors are arranged in parallel capacitor at the entrance to the supply network. The switches short circuit or separate in order to obtain the desired brightness level. The main advantage of this solution is its simplicity. With such schemes is necessary to begin the implementation of its own projects, if there is no experience with electronic schemes.
But this example is not difficult to understand the significant drawbacks:
- the lack of fine adjustment;
- great loss of power consumption wasted on the resistors;
- abrupt changes in the electrical parameters (current and voltage).
The latter feature, in particular, provokes the formation of discharges between contacts. They create mechanical damage and stimulates the oxidation.
If smoothly increase / decrease the pulse width will vary as desired food. When the duty ratio of 25% instead of 5 V source voltage actual value will be 1,25 V.
Connected to the output FETs, or other high power semiconductor switches. They perform their functions without mechanical switches, which provides increased durability under optimal conditions. Current and voltage control using electronics. For removal of excess heat radiators are used.
Here it is seen as a dimmer for LED lamps 220 "removes" part of the sinewave. In this mode the load is connected with a frequency of 100 times / sec.
If you connect to such type of source LED deviceIt will create a flickering or very bright light at the appropriate levels. For this reason, let a specialized LED bulb for a dimmer. They built stabilizersWhich react properly powered using pulse width modulation.
Advantages and disadvantages of dimmers for LED lamps
The main "plus" when equipped with such equipment are determined by the extended functionality. The relevant performance when connecting external electronic dimmer for LED lamps 220 B will simulate the presence of home owners. Unlike a simple switch you can use a smooth adjustment that increases the realism of the processes.
It should also be noted:
- reduction of energy consumption;
- high accuracy set the brightness level;
- reducing the burden on the connected device by soft start;
- extending the life of the lamps.
The main drawback - the high cost of dimmers for LED lamps 220, which are represented on the market well-known brands. The problem can be solved by the independent production counterpart. It is also necessary to consider compatibility issues with certain lights. Right for dimmable LED bulbs.
However, we must objectively assess the consumer characteristics of the devices in this category, so as not to unduly rely on advertising materials. Pay attention to the following facts:
- Qualitative dimmers for LED lamps 220 provide good stabilization supply current. But it is quite acceptable results can be obtained with the right calculation simple circuit in the capacitor.
- Some manufacturers exaggerate the significance of high frequency transformation, as an effective means for combating pulsations. Some generators work 40 ÷ 50 thousand. Hz. In fact, the human eye does not see more than 60 Hz oscillations.
- Assurances to increase reliability should be taken wisely. The increasing complexity of the circuitry while reducing the physical size increases the likelihood breakages.
- In particular, the chips are damaged by poor heat dissipation. Throws in a standard 220 V power supply also having a negative impact on the electronics. At high temperatures, are easily damaged electrolytic capacitors.
classification dimmers
According to the type of management instruments in this category are divided into the following groups:
The principle of operation of such devices discussed above. By turning the handle clockwise and counter-clockwise to increase / decrease the brightness. Pressing include food and opens a corresponding electrical circuit.
These dimmers for LED lamps 220 modern look. But admittedly, the classic rotary-push model is more informative. Designated position simplifies the determination of a predetermined level. To perform the job action applies a handle. The keyboard versions of complex electronic circuits. There have further blocks that form the control signal.
Such products pose with enhanced functionality. In this model, the user at the touch of a selection activates the half-brightness, saving mode. It draws a flawless appearance, which agrees well with the aesthetics of modern interiors. Practical man like no gaps through which the interior of the housing is capable of penetrating moisture. The design of the rotary handle and no other mechanical parts that wear out with time. Reliable electronic components retain the original specifications in an unaltered state for decades of intensive use.
The main unit is designed according to the scheme typical rotary pushbutton model. However there is additional blocks: receiving, transmitting, processing of signals. Typically, in such constructions use infrared waves. They extend only in the line of sight at a distance of 8 ÷ 10 m (given the low sensitivity of relatively inexpensive radiation sensors). In some models, in addition to standard modes (25, 50, 75 and 100% brightness) can use custom settings by the algorithm timer.
Acoustic Dimmer for LED lamps 220 outwardly may not differ from the standard models. As noted above, some products may be included in the category of intelligent control set "smart House". In this case, in addition to the basic functions of the remote control is added using the Internet communication tools.
Also used for classification of the installation site:
The photograph shows an example of installation inside the structure ceiling plasterboard. In this embodiment, the necessary equipment remote control. When installing infrared sensor not sealed barrier that prevents penetration of radiation.
Such devices are used when operational adjustment of the brightness level is not necessary.
