LED Strip Light 12 Volt: scope and purpose

Today, light emitting diodes can be seen in any lighting, both at home and in industry. This is not surprising. These LED-elements at the lowest cost electricity give light flux, which is much more powerful than conventional incandescent lamps, halogen or energy saving. They are durable, unpretentious in operation and have a much smaller size.

If we talk strictly about LED strip 12, its application as follows:

  • decorative ceiling lights, wall niches;
  • the main room lighting (including high humidity);
  • lighting shop windows, billboards;
  • interior lighting cabinets;
  • Automotive industry.

When mounting the LED strips will be understood, for which it will serve. Based on the destination (main light or lights) is made by selection of the strength of the luminous flux required of the belt.

Light strips can be used as backlighting or general lighting

LED LED-tape 12: Advantages and Disadvantages

Among the shortcomings LED-belt can be noted only 2 - high cost and the length of the strip is at most 5 m, due to the need uniform luminescence over the entire area. However, these drawbacks are gradually receding into the past - the cost is reduced, and the maximum length... Today on sale there are 200 m coils, and thus, the second disadvantage is eliminated.

Light strips in coils of 200 m have appeared recently

The merits of such a lighting element quite a lot:

  • compactness;
  • easy installation;
  • flexibility;
  • low voltage and low power consumption;
  • operational safety.

The list goes on for a long time. In any case, it is clear that the LED strips 12 - the perfect solution for residential lighting.

Not only aesthetic, but also safety. Highlighting the steps - quite a useful thing

As marked LED-tape

To begin, we suggest to pay attention to the table below. It will help to decipher the coded light bar correctly.

Now Let us examine in more detail the basic parameters.

Number of LEDs 1 meter

This parameter directly depends on the brightness of the glow. For example, take the tape with light diodes 3528. The minimum number of elements in it - 30 pcs / m.. This band is suitable for covert illumination soft suspension or stretched ceiling. If we take the maximum density -. 240 pcs / m, then it will be full coverage of the main premises.

And light output power per meter LED strip 12 Volt

The light output (light intensity) is a direct function of power, which in turn depends on the type and density of the LED elements. Expressed light output in lumens per meter (lm / m). Calculate it easy. We learn from the documentation luminous flux of LEDs and multiply it by the number of elements in a 1 m band.

For nightclubs such illumination is indispensable - it allows you to translate any idea into life

The brightest LED ribbon 12 volts proposed today is to strip the LEDs 3528 and a density of 240. Its light output of 7200 lumens.

Waterproof LED strip 12 Volts: the selection and application

Waterproof light bar is marked as IP68. It is a conventional tape coated with sealant or placed in a silicone tube. This completely prevents the ingress of moisture into the light even when immersed in water the band.

GOOD TO KNOW!

If you need lighting or accent lighting in the bedroom or living room, then to acquire a strip with IP68 unprofitable. its value is much higher. Also, when light in a conventional bathroom enough IP65.

Light strip with protection class IP68 can operate underwater

The choice of components for the installation of the light band

Few understand how the mounted light bar. You need to know what components are sold separately. The major ones could be called 12 PSU In a battery with the same voltage, and a controller with a remote control. Let's try to understand why need these additional components, and how to select them.

Power supply 12 volts to the LED ribbons

Power unit - a special device which transforms the voltage from 12 V to 220 and stabilizes voltage. Only if it can be operated to connect the light strip. The choice of this circuit element is very important. It is based on several factors such as the power of light diodes, the density, the length of the strip. Buy a transformer 220/12 V for the LED strip can be in any store that sells light strip.

Power supplies may be of different shapes, but the function they perform one

The correct choice of power supply - the key to long-lasting, stable operation of the light bar.

Akkumulyator12 Volt for LED strip: the nuances of selection

If you want a standalone lighting or electricity cut off periodically, it is necessary to purchase the battery. The choice of this element is similar to the selection of the power supply, however, there is one caveat - you need to calculate its capacity. The larger it is, the longer the lighting be able to work offline.

Controller for LED strip 12 Volt: what it is and why you need it

If you plan to light mounted from RGB-ribbon (light bar with the possibility of changing the color), you must purchase a controller with a remote control. This device is included in the circuit between the power supply and the light stripe. remote control by using the controller, the user can change the color of the backlight can also be zonirovat room (if two or more controllers) depending on the wishes and mood.

Such a controller for RGB-strips can be purchased at a price of about 5000 rubles.

How to connect the LED strips 12 Volt: practical advice

Difficulties in connecting light bar no, the job can handle even the novice handyman. However, there are some nuances that can not close your eyes. The first thing you should know that if one power supply unit connects multiple segments of 5 m, the series connection is unacceptable. This will lead to the fact that next to the transformer light emitting diodes will begin to fade due to burning-off tracks. Connect segments should be parallel.

Option connect luminous bar to the power unit

The next thing to note - this is the shortening of the strip. If you look at its front side, you can see the cutting line. In other places, it can not be cut. Try to understand some aspects of installation in more detail.

Connecting the adapter: you need to know

The power supply is connected in accordance with the marking of contacts - here will understand even a child. Input power 220 is made on the 3 terminals:

  • N - neutral;
  • PE - protective earth;
  • L - live wire.

On the strip or monochrome controller unit 2 goes wire. They are labeled as «V-» and «V +». Buy Adapter for LED strip can be inexpensive through online resources.

VERY IMPORTANT!

When you connect the power supply to the 220 V, be very careful. Before starting work, remove the tension by turning off the automatic opening. I do not think that it is possible to make the switch - even if it is connected properly and it is crossed by phase, has not been canceled, the reverse currents. Can "fly" and a zero conductor.

Dimmer - what is it, and how to connect to the diode tape 12 Volt

When installing single-color light dimmer band - pretty handy item. In simple terms, it is a rheostat, which reduces the electricity supplied to the strip. It is installed in the gap between the power supply and the light stripe. Included usually comes remote control to control the light intensity. It is worth mentioning that the dimmer really extends the life of light diodes by reducing the intensity of their glow because they are no longer constantly operate at full capacity.

It looks like an inexpensive dimmer. You can buy it for 300-500 rubles.

Buy dimmer for LED strips 12 Volt can also be on the website, however, experts advise to buy these types of devices in the audited stores. High risk of acquiring the goods of inadequate quality. In this case, the store is always possible to change the product in the presence of the check.

Do not try to change the dimmer, if it is out of order your fault - an experienced seller immediately notice it.

Wire for LED strip 12 volts: the required section, soldering

For mounting considered optimal trohzhilny copper wire of 1.5 mm2. Pike made copper contacts tape. It should closely monitor the polarity. If you mix up the plus and a minus, light emitting diodes illuminate the strip will not. If we mess around with a soldering iron does not want to, you can use special connectors. They are acquired in the same stores or through the Internet.

Section of the wire 1,52mm enough. If the wire is thicker, will be loss

Nuances connecting light bar to the car

Many people think that if the necessary voltage for the LED strip 12 volts, for cars it would fit perfectly, even with a direct connection, however, is a strong delusion. Voltage onboard network of cars floating in the range 12-14,5 V, and thus, directly connecting the tape, we obtain lighting that has been operating for over a week. Here are a few solutions.

The most common is to set the limiting resistor at the positive input. However, with such inclusion during engine operation will "float" the intensity of the luminescence diodes. If uniform illumination for the motorist in the first place, you can use another method.

Connecting the light bar to the onboard vehicle network

You must purchase a linear voltage regulator (SLS). In fact, it is an integrated circuit (IC). The best choice would be a LM7812, but only on condition that the system voltage does not fall below 14 V. Otherwise, the light emitting diodes are noticeably flicker. If this occurs, it is best to set the SLS as the LM317, rated at 12.3 V.

LED Strip Light 12 Volt: the price per square meter depending on the parameters

It is clear that the cost of the light bar will be completely dependent on its performance. To our dear reader it easier to navigate on prices, Tehno.guru edition collected the prices of various LED strip with the characteristics of a single table. Average rate as of August 2018.
