How to choose and cut a dimer for LED strip
Title: Svetlinna LED strip 
Possibility for adjusting the brightness on the lighting device is not convenient, but it is a clear and simply irreplaceable function when organizing lighting and backlighting with LED strips. But for yes, you will get the result of desire, tryabva clearly and understand how the dimers (dimeri) represent, how they work and how they represent. Again, ask for help and help you choose the right dimmer for the LED strip (SL) and, if necessary, put together your own useful device.

What is the shading
Obscured (from English dim - obscured) e was changed into brightness for lightening. Dimer the dimer in response, that is, the electronic device, which somehow allows you to smoothly change the brightness to the lighting device. Try on for nai-sorry dimery sa rheostat and autotransformer, which will exchange the voltage in the product.

There are many varieties of highly efficient and compact electronic dimers, which work on various principles. But all the same, Ima is one and the same task: yes, change the power, divided into goods (in our case, into LED tape) and silat into a light stream, removed from it (brightness). Thy kato se is interesting from dimery for LED tape, some kind of spray on technite varieties.
species dimeri
Pandelkite, as you know, they will offer it in single-color and multi-color.Find out the options for multi-color pandels with RGB (red, green blue) and RGB + W (red, green blue, white). There is a difference between the use of RGB and RGB + W e, which in the first case of tape using separate LEDs with different colors, arrangement separately or in groups, but in its own way: R-G-B-R-G ...
RGB tape
RGB + W tape from the use of four-color LEDs, consisting of a few crystals, placed in a single device. By activating these or onesi crystals, you can and will achieve a lot of additional colors, including white. You can underline and tri-color tri-crystals RGB 5050 LEDs, which still work on the principle of mixing in color.

For the option with a multi-color tape, disassemble it, you need a special type of dimer, which can independently control three channels.
Osventova dimerite for LED strip se differs with:
- method on control;
- starting with installation and location;
- additional functions.
Method per control
When using the LED strip control method, dimming can be divided into the following four groups:
- vrtyasch se... Adjusted for brightness on tape in taquiva dimeri se perverted with the help of conventionally twisted se smoke. In Tozi, the case of inclusion / exclusion can be perverted somehow through the smoked smoke, and through the onslaught;
Vgradeni and surface mounting dimeri with vtoryascho se smoked
- Push the button. In this device, the brightness for clarification is regulated with the help of a common key, such as a switch, or a mechanical button;

- network. The device is controlled from the butoni sensory. It’s not necessary and all the onslaught, you’ll just gibberish;
Dimer ss sensor control
- remote control… It is necessary to determine the illuminance for the tasi, the category of the controller and set it remotely with the help of a lifeless IR or radio remote control. Some of these devices are equipped with a Wi-Fi module or microphone. They can be controlled from a mobile device, but they can be echoed through the voice.

Starting on the installer and location
Today dimery for lenti is offered in various designs. Depending on the task and the design idea, you can choose the most suitable design for you.
Behind the wall installation
Usually (but not necessarily) the device has a format and size that is not conventional. Those sa vdlbnati in a stenata or an imat construction in the mountain. A much more convenient option for organizing for clarification or lighting for days.
Dimery for citizens and surface mounting for wall mounting
Behind the screen installation close to the tape
It is not at all inconvenient if the wall construction is used or it is difficult to install it (for example, do not search and make many repairs). In this case, dimerat can be placed close to the ribbon or in any convenient place. For example, hide here behind the interior elements or into the space on the tawana. Graded device is perfect. More tryabva and control such a device remotely: with the help of a cable or remotely control.

Additional functions
Time dimming, in addition to the main task and adjusting the brightness, it can and perform a huge number of additional functions. Since the appearance on the microcontroller, it has stopped and there will be great pleasure.Usually such dimers are called LED tapes and controllers, but it’s even more difficult to call them dimers.
Nai - interesting from the function, expel from the controller:
- Switched on through a timer (imitation for ownership of the owner).
- Syzdavane for light effects (light light, periodically pale, promyana for colors, etc.).
- Music mode (using the microphone).
- Integration into an intelligent home or connection with a computer via a cable interface.
- Entrance to the outside of the sensory (alarm, svetlina, etc.).
- Possibility for self-programming.
Tosi controller for LED strips can not be called a dimer: it can be programmed and integrated into an intelligent house with a few dozens of additional functions
Selection Criteria
Do you decide and direct the lighting with LED strip and dory go buy it at the same time as it is stored? It's scary, stay and choose and buy a dimer. We will choose a dispute according to the following criteria:
- Save voltage and power... The voltage on the dimer is working, even if there is a cathode on the ribbon - 12 or 24 volts. What does it have to do with power, it’s shaking and it’s 15-20% higher than the power on the tape. Ako ima nyakolko lazy, togawa capacitetit im sebira and 15-20% e necessary border on security. Dimer, working for the frontier at his own opportunity, yama and spend a long time.
- Broy channels... Tazi characteristic depends on the type of tape you use. For a monochrome tape, there is a sufficient conventional single-channel jumper. RGB or RGB+W? A multi-channel dimmer is required and there is no effect, which can be realized with the help of a second type tape, access to the RGB dimmer and vice versa.
- Construction and management… Graded, surface or concealed mounting. Vsichko depend on the idea and lekotata on the floor. Taken from the method to control. Butoni, senzori, vrtyascho se smoked, remote control - tova, somehow haresvate nay-good and nay-conveniently for you. But there are some sensors and even more remote control via Skype.
- functional... Schematics are sharper, sensible in a good way, don’t work hard. Of course, it's even more tricky and pay a lot of bets for every extra feature. So, for example, you can’t control the fields from a smartphone or even integrate them into the system for a “smart home”, then it’s not necessary to take the device with such an interface - you can still use propylene.
Scheme on the wire
It is connected to the LED tape dimer and not from the forest and not from special tools. You know, base on electrical engineering, togawa you can do the work yourself, without including a specialist. For yes, turn on the dimmer, or turn it on sufficiently between the source at a constant voltage (storage) and the LED tape. In this case, parsing it, it is necessary and all the spasm of polarity and not the sebark of entry and exit to the device.

Direct si dimer
Woe-dale sme izmislili dimerite for LED tapetata. Time and figure out how to direct the dimer with your own mind and whether it is possible in general.I don’t know your field for training, but focusing on the top, there is only one simple enough scheme. Worked on an accessible element base, but performing a good function on a dimer and still take it for a standard key.
Simple dimer chain for LED strip, using PWM dimming method
Classically, a multivibrator with a change in the work cycle is switched to transistors VT1, VT3, and the mechanism on the multivibrator is reinforced with a transistor VT2, which forms a push-pull switch with VT3. The capacitance on the capacitor C2 and C3 is such that the frequency cycle on the oscillator is always working even at 14 kHz. The comrade's trembling and ringing on the ribbon with a low brightness. Work the cycle of changing with the help of changing the resistor R3.
The multivibrator is charged with a powerful key, directed to field-effect transistors (MOSFET) transistors VT4, VT5, connected in parallel. Diode VD1 is a pre-transistor transistor from voltage to reverse induction, which can somehow be used to protect the line on SL, which is enough for a long time.
Schematic diagram from the field effect transistors with N-type channel. Ami ako intend to be similar to the channel from type P? OK e. The samata of the chain for the dimer does not try to change it, it’s enough to change the extreme torment to the exchange resistor R3 and yes, change the turn-on of the VT4, VT5 chain.
Option for P-channel FET dimer
This device is osiguryava regulated for brightness on tape from 10 to 90%, which is not good for such a simple chain.
Now for the details. KT315 and KT361 sa very well cross transistors of amateur radio environments and can be used in almost any home appliances from the 90s. Dori now te struvate a few rubles in the KeTeshki store.
Turn the transistors off to the side and get rid of any given handkerchief on a defective computer. Ako power on the SL is not above 35 W, then the transistors VT4, VT5 can work without a radiator. Ako power is higher, togawa, sort it out, a radiator is also needed.

Almost everyone, who thought about buying a dimer, Ima ask a lot. More experience and dissuade on nai-popular.
Is it smart to install a dimer?
You can read the trace of this tazi statia, probably you were weird - did you install the dimer? Are there any other significant shortcomings in the project? Some kind of device, dimerat ima predominance and lack. Let's summarize in a table:
predominancelackPossibility for brzo sazdavane on a convenient field for illumination with the help of a light illuminating body. It is especially convenient, sometimes you can use lifeless remote control. Additional steps (a high-quality multifunctional controller can also be on-scoop from the lighting system) Possibility for programming and setting up various lighting effects in automatic mode. Suitable not only at home, but also for entertainment centers, shopping centers, for use in decorative lighting. The effect is especially white, kogato nivat on the brightness of the mood on the bottom.
And so, the main lack of installation on the controller for the LED tape is a high price. But here we are talking about the full value of multifunctional controllers.From the function, just tryabva and choose these, from which you need it, but the dimer is ordinary without additional functionality, dory from the well-known brand, e get evtin. In addition, simply connect to a dimer and allow and refuse the service of a qualified installer, which is not free of charge.
What this refers to treptene, it is characteristic of the very low cost products and devices from Made in Nouname. If you buy a device from a normal (not necessarily well-known) manufacturer, no problem with treptene.
With the installation on the dimer, the result is comfort and convenience. This is why, they gave me a system to ask questions and installed it, but I personally dissuaded the bih: it’s a system.
Do you put on a nakakva tape or not?
Ako dimertima is sufficient power and supporting the need for a strong channel (talking for a channel in a mountain), then in addition to the same pasture for all SL with the removal of a strong channel, it was designed for a high voltage of the cathodimer. The lights of the LED strips are adjustable, but they are protected… The only thing you need from a special dimer is designed for reveal work with LED tape, and not the tazi, which is installed in the keynote for managing the crash in the polyley.
Now you know, for dimming for LED strips, almost everything, for some tryabva, you know for the right choice and independent installation. And theses, which offend and hold a poyalnik in the r’zet si, trace the kato to read the tazi statia, put it on, they’ll gloat the forest is simple, but they will get the dimers themselves.
