Flexible LED strip-a unique gift for all professionals and designers, which allows you to implement a variety of complex lighting projects. This is an additional lighting element in the room, which can become a real "highlight" and an original decor. The scope of application covers interior design, decoration of advertising signs, organization of lighting in the premises and on the street.SCOPE OF USE OF LED STRIPThe device is a flexible circuit board, on a flat surface of which diodes are fixed at an equal distance. Proper operation is ensured by resistors, the main task of which is to limit the current passing through the semiconductor. Each element is connected by conducting paths. Power to the entire system is provided by special adapters. The main function of the adapter is to convert the voltage coming from the electrical network to an acceptable voltage for the lighting device-12 or 24 watts.They differ in the color scheme and intensity of the glow. Nizhny Novgorod has specialized stores where you can buy LED strip white, blue, green and red.The white version has the largest number of shades: < li>cold – the radiation is slightly bluish, corresponding to a color temperature of 10000 oC; < li>a normal white shade, equal to a temperature of 3500-5500 oC;< / li>a warm shade of white, corresponding to a temperature of 2700 oC.< / li>< / ul>To solve certain problems, a simple device with monochrome radiation is not enough, in this case, you can organize the illumination with a model that reproduces different colors. This is the most versatile solution – in this case, each light bulb reproduces one of the monochrome shades-blue, green and red. Depending on the amount of each of the shades, a certain color is formed when mixed.WHERE IS THE DIODE TAPE USED?Automotive sphere< / li>Diodes are installed in the headlights of vehicles. Such illumination is not a whim of the motorist and not an idle desire to decorate the car, but a very specific requirement of the traffic police. By the way, the use of such lighting devices in headlights is much more economical than the usual incandescent lamps, and their operational period is much longer.If there is a desire to give the car a personality, it is enough to install a red LED strip or any other color under the body.Note: < / strong> The special feature of such lighting devices is their resistance to vibration, that is why this method of lighting is especially appreciated by motorists. < strong>Advertising sphere< / li>In stores, the tapes are used to focus on products or certain areas of the room. With the help of a red or green model embedded in signs and billboards, you can significantly expand your target audience.Home lightingDecorative lighting of the aquarium, ceiling, and interior of cabinets.In the kitchen, the use of diodes allows you to create a comfortable environment for cooking.Additional illumination of the TV or computer monitor. Watching movies in the dark negatively affects a person's vision, as the sharp contrast between a dark room and a glowing screen causes a burning sensation and a sting in the eyes. That is why the low-power lighting will create a comfortable environment for the eyes. It is best to place the light source behind the TV, in the case of a computer, you can simply stick it to the back of the monitor.Repair of computer equipment. When the lamps that illuminate the screen fail, they are changed to LEDs. At the same time, such castling does not affect the image quality, moreover, the durability of the backlight increases. The only drawback is that the installation will require a technical revision of the monitor circuit.The light in the room. Ordinary lighting can easily be transformed into the main light source, it is enough to distribute the LEDs on the ceiling above the level of the stretch ceiling. The advantage of such lighting is the ability to adjust its intensity.Night illumination. If you evenly distribute around the perimeter of the room, for example, a blue model of low brightness, it will perfectly replace the night light.Emergency lighting. For this purpose, red light diodes are best suited. The service life of this option is several times longer than any other.Street lighting. Some models are reliably protected from climatic events. They are installed along the paths in the garden, from the house to the gate.< / li>< / ul>< / li>Note: < / strong> such devices provide a powerful, bright glow without the use of additional light filters, which are usually quite bulky. In addition, the ribbon illumination saves the use of electricity, reduces the load on the network and the battery.< / p>WHAT KIND OF LED STRIP CAN I BUY IN THE STORETypes of diodes - SMD 3528; - SMD 3014; - SMD 2835; - SMD 5050.< / li> < p>The numbers indicate the dimensions in millimeters-3.5 by 2.8 and 5.0 by 5.0, respectively.The accompanying elements are resistors and pads where the wires necessary for power supply are connected.Note: < / strong> Any model is constructed from segments with a dividing line drawn between them. It is on it that the tape is divided into segments of the desired length.Color Management< / li>In the case of the monochrome version, the contacts are simply signed - " + "and" -", these symbols determine the polarity and sequence of connecting the device to the power source. < p>There are four outputs for color:< / p>"+12" or "+24";< / li>"R";< / li> "G";< / li>"B".Note:< / strong> If you connect the same pin value to the "+" pin of the power supply, and connect the minus pin to the same value of any letter, the ribbon will glow with the same color you selected. If you want to control each shade, use a special controller.Fasteners< / li>On the reverse side of all devices there is an adhesive material by which the lighting device is attached to any surface. The main thing is to pre-clean it from dust and degrease it.Versions< / li>In the simplest model, the diodes are not additionally protected. It can be used exclusively in residential areas with low humidity levels. Unprotected LEDs should be installed in such a way that they are not touched and not once again touched.For rooms with special operating conditions (high humidity, extreme temperature conditions) , we recommend purchasing a device with a special coating that prevents the penetration of moisture, dust and protects against the effects of extreme temperatures. The cost of the LED strip with a protective layer is higher, but the money spent will pay off with high reliability and durability.Note: < / strong> a special gel or polymer composition is used for the coating. In addition to the protective function, the coating plays the role of a lens that diffuses light.METHODS FOR CONTROLLING THE BACKLIGHT RIBBONThe control of light diodes involves:< / p> < li>brightness control;< / li> < li>setting the desired shade.< / li>< / ol>In order for the entire system to work smoothly, without failures, evenly and efficiently, it is important to correctly select the associated equipment, which is conditionally divided into four groups:Power supply;< / li>Controller-it is used to adjust each shade;< / li>Dimmer – required to adjust the brightness of the radiation;Power amplifier-it is installed to maintain the operation of the controller and dimmer in the case of connecting a high-power system.< / li>< / ol>POWER SUPPLY< / h3>The main function is simple activation.The principle of operation is to convert the voltage of the household network (220 V) into the voltage or current required for LEDs.Connection method – one device is connected to one adapter. When there is a need to connect two or more at the same time, use the parallel connection principle for power supplies with voltage stabilization and serial for power supplies with current stabilization. It is important to remember that the unit is designed for a certain power and load that the LEDs create. That is why, when planning a lighting system, it is important not to exceed the permissible limit and make a margin of 20%. To calculate the maximum block limit, you need to multiply the power of one LED element by their number.Maksiled stores offer a wide range of < a href="" title="Catalog power supplies">power supplies < /a> that provide the maximum service life of LEDs. < h3>RGB CONTROLLERThe control controller is used to control the glow shades. Using the remote control, a certain intensity and power of each base color is set. In accordance with this, the LEDs are supplied with the set voltage. As a rule, the remote control allows you to choose the mode of smooth change of shades or one of the built-in modes. < h3>DIMMERThe part is necessary to adjust the brightness of the glow. Consumers often ask – why can't a conventional variable resistor be used? The answer of experts: the correct operation of the lighting device, first of all, depends on the incoming voltage. By simply lowering the voltage value, you can turn off the lighting system. The brightness depends on the duration and frequency of the pulse current – the more often the LED flashes, the brighter and richer the radiation. With a decrease in the frequency and duration of the pulses, the radiation becomes dimmer.Note:< / strong> such blinking when controlled from the controller is not perceived by human vision.
