Modern electronics often equipped with external power supply 5V, 12V, 19V. Once the device is out of order, they are often lying in a closet or locker. Читать далее
LED strips
Accessibility and ease of modern lighting allows you to install it on the car.In addition to the internal tuning and soffit replacement of conventional lamps to LEDs, the car uses LED strip to improve the lighting in places where the light never was.
Before I tell you how to connect LED strips to 110 volts, divide them into 3 types, with different voltage work. Читать далее
A couple of years ago I was doing repairs in the new apartment, purchased in the new building. In view of the limited budget we had to make repairs easy. Now, I settled down and it is possible to make a false ceiling and new lighting. Читать далее
The introduction of new lighting technologies allow you to conduct your own hands calculation and installation. I’ll tell you how to choose the right plastic and aluminum profile for LED strip. Many simply do not know that cooling is required. Читать далее
Diode lighting widely used in our homes, and quite a big success, it displaces the halogen bulb out of the car. Today, a closer look at how to set a flexible LED strip lights for cars in or out. Читать далее
As an inveterate electronics, continue to share experiences and best practices. I try to express, without technical terms, that it was clear from the child to the grannies. On this overcast day we will choose the right power supply for LED strip 12V, hereinafter abbreviated as «PSU». Читать далее
Many planning a lighting and either do not realize that there is a LED strip 220V. It does not require power supply 12V, only miniature straighteners, through which plugs directly into a power outlet. Читать далее
Consider the most powerful LED Strip SMD 5630 and SMD 5730. They are much inferior to the popularity of other modifications on the diodes 3528 and 5050. Set them only on the heat sink in the form of the aluminum profile or on the surface, capable of take the heat.

I decided to devote an entire section LED strips, with their apparent simplicity, there are many nuances. At first I wanted to write a few articles, but their number has exceeded 15 units. Tape light source to help designers translate their ideas into all interiors. By using RGB technology, consisting of three primary colors by mixing them can receive any other colors and shades. Colors can change the room according to your mood.
How to choose the best
Because of the Chinese products on the market and more offers of Chinese online-shopping, choose the good it was very hard. With cellar technology from China, sold a lot of bad products. It seems like there to cheat, LED and resistor, all simply as three rubles. But the Chinese marketing and here came up with hornblende. They began to produce the type of fake LED diodes to it in standard housing put a weak crystal that emits light. He is 3-5 times less than the usual brand and the luminous flux indicate how good of brand. For example, SMD 5630 from Net-Aliexpress store less than brand-watt SMD 5050. And the issue of trehvatnye, they have the same body.
did some investigation and calculations made by the ratio of the value of 1 Lumen, that’s not taking into account other characteristics. It turned out that to buy more expensive in China than in our online stores. Thus it is necessary to wait 2-4 weeks, the service life of less used the weakest and cheap LEDs. On the one hand plays a factor, then they work and count how long it lasts very difficult. Also unknown manufacturer, and if the manufacturer is not indicated, then the quality of no worries, because you can not even write a review, not knowing the name. Good products, eg Fearon, Kamelion, monitor quality, give a guarantee. Compared to the unmarked from the tea she served 2-3 times longer. And work on the replacement very difficult, and there are quite a few. Taking into account all the parameters, unnamed proprietary better 3-4 times.
I do not advise anyone to buy without said producer, checked my experience and colleagues.
backlighting ceilings and kitchen
The most popular application is the use to illuminate the ceiling. There are some good options for installing the ceiling, for each of them I have drawn illustration, just turned 10 pieces. This will help you immediately do everything right and get the desired result. It will save your money and nerves, as I had to redo highlighting, tearing it and re-attach adhesive.
Hams big fan of tinkering from scrap materials. The articles have unusual ways to save when buying components:
- to not spend money on an expensive aluminum profile, you can use a cable channel that is any color and different finishes for wood and stone;
- 12V power supply can be used on laptops, televisions and other electronics that are lying around in your house;
- to highlight the work hones in the kitchen is not blind, instead of the aluminum profile with a matte lid, you can use the base of the cable channel with high walls that will direct the light downwards only.
If you are designing a basic lighting, I gave an example of a simple calculation to my room on the 20 squares. Similarly you can calculate lighting for your space, that it is in compliance with the norms of minimum illumination.
backlighting on cars
Tyuningovschiki quickly implemented LED ribbon for decoration domestic sports cars. Compile a photo album of the places where it is best to put on the car, from the interior and finishing bottom and head headlights.
Some even manage to use the tape as a diode daytime running lights, which absolutely can not do. This is a complete disregard for the norms of lighting devices of the vehicle. Surely on the road, you kind of machines with fluorescent lights, with whom is like the brightness of side lights. DRL should be like a flashlight shining forth with light in an angle of 30 degrees, and it shines at an angle of 120 degrees. To find out the brightness, they checked their night-type blind, so powerful. In the dark, all led diode 1 watt will dazzle. I advise you not to invent and not to save on their safety and others.
To work long-term on-board network, you need to set voltage to 12V, or a high probability of premature failure due to surges, which can reach 25 volts. LEDs do not tolerate higher than the rated voltage.
Connection and Installation
Special attention is paid to the correct parallel and serial connection. The main feature of it is working on 12 volts or 24 volts. With an average power of 14 watts per 1 meter length of 5 meters will consume 70 watts. When a voltage of 12 volts the current will be about 6 amps is enough. Thin copper base will heat up, and the voltage drop. In order to reduce the cross section of conductors and current, applied voltage of 24V. The current intensity is reduced by half, and can increase the capacity in 2-fold.
Most of the other connections have ice on the 220 tape, for it does not require the power supply to 12V. Also called a street, the house is not recommended to use it. Leda on it are connected in series of 60 pieces, so do not require a low voltage. It protects the silicone or PVC coated to protect against electric shock. The length of the whole length of up to 100 meters, it is the whole bay. At low voltage only 5 m.
Power supplies and controllers RGB
The articles focused on the power supplies of the tea. Wanting to save money, many are beginning to look for a suitable Aliekspress, especially when doing it the first time. Honest specifications indicated only 30% of goods with those who dearly. If low-cost model indicated that produces 60W:
- This could be the maximum peak power;
- Real roughly 40W;
- it heats up due to poor design and poor quality electronic components;
- due to a combination of the first three factors, he quickly gets out of order.
Special problems with RGB controller I have not seen, remote controls work well. The greatest demand is for 3 models that are optimal for the parameters and are very good. Novelty was Wi-Fi controllers and single-color three-color RGB. Remote control acts smartphone with wi-fi and a special application. The selection is made by clicking on the color wheel. Wireless WiFi interface is already on conventional light bulbs, integrating management across the wireless network, you can easily build a system of «smart house». All the features of your dwelling, such as apartments, are centrally managed, including remotely through the Internet.
