Today, LED strips are one of the most popular devices for organizing primary and secondary lighting. They are used for domestic and industrial purposes. Tapes allow you to make a bright advertising sign and create additional illumination of the working area in the kitchen. They adorn the interior and exterior of various buildings.
One of the most popular varieties of the presented products is the LED strip 3528 . To choose this device correctly, you need to know its main characteristics and properties. They will be discussed later.
general characteristics
Thoughtfully and responsibly it is necessary to approach the choice of LED strip LED. SMD 3528 tape is a device that consists of a flexible board with printed contacts. On it in a certain sequence are diodes. They emit light of the required power.
The thickness of the flexible board does not exceed 2 mm. The width can be different (8-10 mm). The structure also includes resistors. They limit the electric current that is supplied to the diodes. Lena type SMD today is extremely popular. They are relatively inexpensive and durable. They can be used for a variety of purposes. The presented tape can work out 50-100 thousand hours. Electricity consumption by diodes is the most economical.
Most often, type SMD tapes are used for internal illumination. It allows you to decorate the interior, highlight certain areas in the room. It is also used in shopping and entertainment centers, various salons and other facilities.
LED Type
Diodes are the main element of the system. They emit light of a certain hue and intensity. It depends on them in which area the device will be used. LED strip SMD 3528 belongs to the group of one-color varieties. It can emit white, blue, green, red or yellow. Such diodes cannot change the shade.
Type of SMD diodes (Surface Mounted Device) mounted on the surface of the tape. They are controlled by a controller. The radiation power depends on the density of the arrangement of the elements of the diode type on a flexible board.
SMD type tape is the most demanded today. It is used in dry, clean rooms. This is the cheapest LED strip option. She does not have high protection. Diodes when placed are in the open. Therefore, splashes of water, grease should not get on such a tape, a large amount of dust should sit down. If you want to use the device in a humid room, it is better to give preference to other options for boards. Also, if you need to create several shades of lighting, you should purchase RGB class tapes.
Diode size
SMD 3528 LED strip has a certain luminous power. This indicator determines the size of the diodes. The marking indicates this indicator. Knowing what the type of SMD tape means, it is necessary to consider the numerical value of the instrument presented. It indicates the size of the lighting elements of the tape.
For example, a customer purchased a 3528 white LED strip. The four numbers shown indicate the size of the diodes. Their length is 3.5 mm and their width is 2.8 mm. There are tapes with large dimensions of the diodes. They can create bright, self-contained lighting. The tape can be used instead of a conventional lamp. The size of 3528 diodes is almost always used to create additional lighting.
One element of such a tape is capable of emitting 5 lumens of radiation. This is a conditional measure for the intensity of the rays of the device. Other sizes of diodes can shine brighter. For example, a size of 5050 can emit 15 lumens, and a diode 5630 can emit 18 lumens.
Number of diodes
In addition to the size of the lighting element, the brightness of the glow is affected by their concentration per 1 m of tape. The lowest concentration of diodes is 30 pcs. These are the dullest devices. Their scope is quite limited. The most popular is the LED strip 3528 LED 60. For 1 m of linear diodes, there are 2 times more than in the previous device.
The maximum number of 3528 diodes on an SMD tape can reach 240 pcs. At the same time, the presented product will be able to fully illuminate the room. Such a number of diodes can be used only for SMD 3526 tapes. If each element has large dimensions, their maximum number per 1 m can be no more than 120 pcs.
At the same time, the energy consumption of the tape directly depends on the indicator presented. To correctly mount all the elements of the system, the master necessarily calculates all the characteristics of the tape. This gives him the opportunity to choose the right power supply.
Glow power
LED strip 3528 (60, 30, 120, etc.) has certain power indicators. This indicator must be taken into account when connecting the device to the network. Power specifications are measured in watts. There are certain values for this indicator for type 3528 tapes.
If there are 60 diodes on the surface of the tape, 1 m of such a device will consume 4.8 watts of electricity. Accordingly, with an increase in their number to 120 pcs., The power will increase by 2 times. It will be 9.6 watts. The maximum meter running tape can consume 16.8 watts of electricity. In this case, the concentration of diodes is 240 pcs.
If you want to create local lighting, the power of the device can be up to 10 W / m. If necessary, make a full, basic backlight, you must choose devices with a power of 14.4 W / m. Also, the presented tape parameters are taken into account when choosing a power supply.
Rated power
When choosing an LED strip, its rated power must be taken into account. This will allow you to choose the right power supply. Without it, the tape will not be able to work from a household network. This will require a simple calculation. First, the power of 1 m of linear product is determined. For example, a customer purchased a 3528 (120) LED strip. In other words, there are 120 diodes on it.
As described above, the presented lighting device has a power of 9.6 W / m. If the entire tape has a length of 3 m, its total capacity is:
9.6 x 3 = 28.8 watts.
The power supply must be selected 20% more than the result. This will ensure the normal operation of the lighting device. The power supply should be about 35 watts.
Adapter
LED strip 3528 (12V) today is the most common version of such equipment. It connects through a special adapter. It is designed to convert the current of a household network to the required level. Also, when connecting LED strips, adapters 24 and 36 V can be used. They relate to professional equipment. For domestic purposes, the most commonly used power supply is 12 V.
The type of adapter that you want to connect to the tape is indicated on its label. Therefore, when buying, you just need to look into the manufacturer's instructions. The power supply complies with the requirements presented. Otherwise, the tape will not work.
Experts do not recommend purchasing a power supply with a large supply of power. An indicator of 20% above the obtained value will be quite enough. Otherwise, you will have to pay more for the adapter.
Quality appliances
3528 LED strip can be a very durable device. However, experts say that only products from trusted manufacturers differ in their long life. The most upscale products are delivered to the market by Maxus, Feron.
To choose a quality device, you must carefully examine it. Diodes should be soldered evenly. There should be no defects in this area. Otherwise, it is not recommended to purchase such a product.
Also, high-quality tapes can be determined by the type of resistor. In such products, they have a resistance index of 150 or 300 Ohms. The marking of such items of equipment will be 151 and 301, respectively. Poor-quality tapes incorporate 100 Ohm resistors (marking 101).
Expert Reviews
LED strip 3528, according to expert reviews, can be used for both local and full indoor lighting. To do this, you must correctly select the power of the device. The presented tapes work for a long time, consume a minimum amount of electricity.
It is not recommended to save on quality. In this case, the use of the tape will be not only short-lived, but also unsafe. The products of the above world brands are known for their long work (at least 5 years). By correctly connecting and selecting the power supply for the lighting device, operating the tape in accordance with the manufacturer's instructions, you can have no doubt in its reliability.
When choosing a system, it is necessary to calculate its power, take into account the scope of the device. Only in this case, the operation of the equipment will meet the requirements of the user.
Having considered what the 3528 LED strip is, as well as its main characteristics, everyone will be able to choose the right lighting device for various purposes.
