A new breakthrough in the world of fixtures is associated with the advent of LEDs, and especially their strip design. The types of LED strips amaze with the ability to create original luminous surfaces of any configuration. Elements are suitable for decoration of arbors, pools, aquariums, billboards and lighting of living rooms.
Design Features
Considered lighting equipment is widely distributed in the field of advertising and trade. Types of LED strips can be divided into the following categories:
- Flexible circuit board.
- Strips coated with silicone (to protect the structure from moisture and deformation).
- Figured variations used to decorate carousels, party supplies and other decorations.
The standard length of the 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 different intensities.
Fixing the tape to almost any surface is carried out through an adhesive base with a protective coating. It is advisable to fasten strips to a rough plane using double-sided tape or intermediate clips.
Types of LED strips: a brief description
The design circuit includes microchip LEDs, corrective resistors, conductors for connection, and contact platforms that provide power to adjacent bands. Reliable connection is ensured through the connectors of the LED system. As an alternative, solder wires in a standard way.
Then the tape is cut into pieces required for installation. Elements are cut to length along the contours of the necessary figures according to the arrangement of the centers. The obtained 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 in groups or function in corner and other figured compositions.
Specifications
LED strips, the types (types) of which can be divided according to several parameters, are primarily distinguished by the supply current. Designs for 12 and 24 volts are provided. Luminous devices are connected via special power supplies. Products that are designed for a standard mains voltage of 220 volts are produced. They are connected via adapters corresponding to the reorganization of the power and power consumption of the device. Usually, the strip with LEDs in the latest version is placed in a transparent 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 intended for installation in rooms with high humidity and on the street.
- Particularly moisture resistant series, operating when completely immersed in water. Used to illuminate aquariums or pools.
Color differences
Types of LED strips by color are divided into two categories. The first includes elements of a monochrome type. They are made in red, blue, yellow, white or green color.
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).
Elements are as close as possible to each other, so their glow is mixed. When changing the intensity of a diode, you can achieve any color scheme. To adjust such tapes, special controllers are used that adjust the color according to the established program.
Since there is no white color in LED strips, it is obtained by coating blue bulbs with a phosphor. After a while, it burns out, and the design glows with a dull bluish color.
Types of LED Strip Profiles
According to the used chips, the bands are divided into the following size groups:
- SMD (SMD) -3028 - 3 x 2.8 millimeters.
- SMD-3528 - 3.5 x 2.8 mm.
- SMD-2835 - 2.8 x 3.5 mm.
- 5050 - 5 x 5 millimeters.
The chips are placed evenly along the length of the strip, and their density is heterogeneous, which allows you to adjust the brightness of the entire tape. As a unit of measure, the indicator of the total number of chips per hundred millimeters (from 30 to 120 pieces) is used.
The types of LED strip power supplies are divided into two classes: analog or digital controllers, which help 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 lighting the dashboard of a car to lighting a whole house).
Marking and interpretation of signs
All manufacturers mark light strips. It turns out a certain sequence of digital and letter codes. The table shows the types of LED strips depending on the ciphers and notation.
No. p / p | Function | Cipher | Decryption |
1 | Light source | LED (LEDs) | Light diode |
2 | Kohler glow | R | Red |
3 | - | G | Green |
4 | - | IN | Blue |
5 | Mounting type | SMD | Types of LED strips for the ceiling and other surfaces |
6 | Chip size / number of LEDs per meter (mm / pc.) | 3028/30 3528/60 2835/120 5050/120 | 3 x 2.8 mm 3.5 x 2.8 mm 2.8 x 3.5 mm 5 x 5 mm |
7 | Degree of protection | IP (IP-68) | GOST-14254-96 standard (can work under water) |
It is worth noting that very often LEDs are used to improve the lighting elements of a car or lighting in the cabin, which makes it possible to achieve a more intense glow while saving energy.
Features
In some bands, standard diodes are replaced by semiconductors having enhanced brightness and radiation characteristics. Such constructions are close to the maximum indicator in terms of light temperature, in size they are larger than usual options. Their main advantage is the creation of a saturated luminous flux, which makes it possible to use tapes as the main source of lighting inside buildings. It is worth noting that such LEDs are characterized by high energy consumption and heat up faster when in operation.
