A new breakthrough in the world of fixtures is associated with the advent of LEDs, and especially their tape design. Types of LED strips amaze with the ability to create original luminous surfaces of any configuration. The elements are suitable for designing gazebos, swimming pools, aquariums, advertising billboards and living room lighting.
Design features
The considered lighting equipment is widespread in the field of advertising and trade. The types of LED strips can be divided into the following categories:
- Flexible PCB.
- Strips covered with silicone (to protect the structure from moisture and deformation).
- Figured variations used to decorate carousels, holiday paraphernalia and other decorations.
The standard length of produced tapes does not exceed five meters. This is due to the presence of thin conductors with low-voltage power, which, when voltage is applied, will glow with differentintensity.
Fixing the tape to almost any surface is carried out through an adhesive base with a protective coating. It is desirable to fix the strips on a rough plane using double-sided adhesive tape or intermediate clamps.
Types of LED strips: a brief description
The design scheme includes chipped LEDs, correction resistors, conductors for connection and contact platforms that provide power to adjacent strips. A reliable connection is ensured by the connectors of the LED system. Alternatively, solder the wires in the standard way.
Then the tape is cut into pieces required for mounting. Elements are cut to length along the contours of the necessary figures according to the location of the centers. The resulting segments are fed with the same voltage indicators, their ends are identical in purpose. This means that the power can be connected to any of them, combined into groups or function in corner and other curly compositions.
Features
LED strips, types (types) of which can be divided according to several parameters, primarily differ in the supply current. Designs for 12 and 24 volts are provided. Luminous devices are connected through special power supplies. Products are produced that are designed for a standard mains voltage of 220 volts. They are connected via adapters corresponding to the power reorganization and power consumption of the device. Usually a strip with LEDs in the latter version is placed intransparent tube, protected from moisture and other external factors.
Types of LED strips for moisture protection are divided into the following groups:
- Unprotected options that are operated indoors.
- Modifications designed for installation in rooms with high humidity and outdoors.
- Especially moisture-resistant series, working when fully immersed in water. Used to illuminate aquariums or pools.
Differences in color
Types of LED strips are divided into two categories by color. The first includes elements of a monochrome type. They are made in red, blue, yellow, white or green.
The second group is universal (RGB). These ribbons can be adjusted according to the color of the glow. The desired shade is obtained by combining three LEDs. The main colors are:
- Red (R).
- Green (G).
- Blue (B).
The elements are as close as possible to each other, so their glow is mixed. By changing the intensity of any diode, you can achieve any color gamut. To correct such tapes, special controllers are used that regulate the color according to the installed program.
Since there is no white color in LED strips, it is obtained by coating blue light bulbs with a phosphor. After a while, it fades and the structure glows with a dull bluish color.
Types of LED strip profiles
By used chipsstripes are divided into the following size groups:
- SMD (SMD)-3028 - 3 x 2.8 mm.
- SMD-3528 – 3.5 x 2.8mm.
- SMD-2835 - 2.8 x 3.5 mm.
- 5050 - 5 x 5 millimeters.
The chips are evenly distributed along the length of the strip, and their density is not uniform, which allows you to adjust the brightness of the entire strip. The unit of measurement is the total number of chips per hundred millimeters (from 30 to 120 pieces).
Types of LED strip power supplies are divided into two classes: analog or digital controllers that help to combine the work of a large number of light elements under a common control unit. Given the principle of operation of the device, knowing its power and characteristics, you can choose a kit for various purposes (from auto dashboard lighting to lighting the whole house).
Marking and decoding symbols
All manufacturers label light bars. It turns out a certain sequence of numeric and alphabetic codes. The table shows the types of LED strips depending on the codes and symbols.
| n/n | Function | Cipher | Transcript |
| 1 | Light source | LED (light emitting diodes) | Light diode |
| 2 | Glow Color | R | Red |
| 3 | – | G | Green |
| 4 | – | B | Blue |
| 5 | Mount type | SMD | Types of LED strips for ceilings and other surfaces |
| 6 | Chip size/number of LEDs per meter (mm/pcs) |
3028/30 3528/60 2835/120 5050/120 |
3 x 2.8mm 3.5 x 2.8mm 2.8 x 3.5mm 5 x 5mm |
| 7 | Degree of protection | IP(IP-68) | Standard GOST-14254-96 (can work underwater) |
It is worth noting that very often LEDs are used to improve the lighting elements of a car or interior lighting, which makes it possible to achieve a more intense glow while saving energy.
Features
In some bands, standard diodes have been replaced by semiconductors with improved brightness and radiation characteristics. In terms of light temperature, such structures are close to the maximum indicator, in size they are larger than conventional options. Their main advantage lies in the creation of a saturated light flux, which makes it possible to use tapes as the main source.lighting inside buildings. It is worth noting that such LEDs are characterized by high energy consumption and heat up faster in working condition.
