While that new formats appear at any time, at the present time, the most widely used is the model formed by ribbons flexibles with a sticker pasted on the back of the Ribbon and contains LEDs with a wrapped type SMD. In particular, they can be obtained in a roll of 5 meters in length, that can connect it with another series to extend the length or parallel roll width. They can also be cut to a certain number of LED each time, being the more usual 3 LED many in our products.
2. Simple installation
-Have a strong 3 m adhesive for easy installation.
-Flexibles ribbons to fit any surface
-Connect directly to the electrical network via a feeder
-Adaptable to any height, length or width
-For indoors and outdoors depending on their degree of protection (IP)
3 types of ribbons LEDs
When we choose ribbons LEDs we must take into account two very specific things:
3.1 type of Leds according to size
-SMD 3528 (3, 5 x 2, 8 mm mm): each LED emits between 3 and 5 Lumens
-SMD 5050 (5, 0mm x 0, 5 mm): each LED emits between 10 y 15 Lumens
3.2 number of Leds per meter (for a maximum brightness)
-60 SMD 3528 LEDs per meter (of 180 to 300 lumens per meter)
-120 SMD 3528 LEDs per meter (of 360 to 600 lumens per meter)
-60 LEDs SMD 5050 per meter (from 600 to 900 lumens per meter)
-72 LEDs SMD 5050 per meter (of 720 to 1,080 lumens per meter)
-120 SMD 5050 LEDs per meter (of 1,200 to 1,800 lumens per meter)
Which one is best?
That depends. For lighting base with low light requirements, a single color and where cost is the key factor, then SMD 3528 prevails.
For projects or RGB most demanding installations, then the best option would be SMD 5050.
The number of LEDs per tape depends on the goals and preferences of the consumer.
4 consumption (depends on the type and number of Leds)
-60 SMD 3528 LEDs per meter – 5 W each meter Ribbon.
-120 SMD 3528 LEDs per meter – 9 W each meter Ribbon.
-60 LEDs SMD 5050 per meter – 14.4 W every metre of tape.
-72 LEDs SMD 5050 by meter – 17.3 W every metre of tape.
-120 SMD 5050 LEDs per meter – 28.8 W every metre of tape.
5. example of application of Ribbon:
-Replacement of fluorescent tubes: more lighting than with a classic tube
-The ceilings and corridors
-Lighting and decoration of niches
-Multiple options of decoration
-windows and store fronts
However, the LED strips are increasingly applied to several places because of its decorative effect, effective lighting, low energy consumption and the ability to cover large areas.
6 installation settings
The SMD LEDs operate on current continuous, it is therefore necessary to use a power source, to be able to convert the usual alternating current, found in any home, running continuous, proper operation of the Ribbon.
7. use of controllers
Controllers and Dimmers of LEDs Ribbons are optional, but recommended devices in the case of ribbons RGB. They are used to adjust the intensity of light, tone color and patterns of the LED strips. They can be fixed or with remote control (IR). Here at smber.com you can get more lighting models.
8. application of Profiles
Profiles for LED ribbons, consists of a profile in aluminium or DMF, in which we can insert our flexible LED strips,wall stickers and cover with a plastic cover. It is used both for the RGB as the monochrome ribbons, there are several types of round coating, etc. for the corners and there are two types of coatings with a different finish: transparent or translucent.
9. plan Installation
After choosing the format to use for the LED strips we know the distance to calculate the power that must have the power supply for optimum lighting of the LED strips.
Suppose we light 20 meters with ribbons SMD5050 LEDs of 60 per meter at 12VDC. . We know that they are sold in 5 meter rolls, so we will need 4 rolls to cover the 20 meters to illuminate. In addition, knowing that each meter consumes 14.4 W we need to enlighten the 20 meters at the same time, a power of 288W (14, 4Wx20m).
Commercial energy sources have a parameter (that each manufacturer makes us) called the effectiveness that takes into account possible internal losses from this source. For example, if this setting is 90% correct power source should be previously calculated power over its effective setting:
288Wx100 / 90 = 320W
Therefore, for proper operation we must seek a higher power source or equal to the calculated energy source. Our choice for this case would be a Source of power Mean Well NES-350-12 of 350W.
10 connection to the power Source
As with any electric circuit LED ribbons must connect the polarity of the circuit. Therefore, the Red wire is considered the positive connector and the black, would be considered negative. These ends must be connected to the power supply by connecting the red son to supply V + or making positive and the black wire to the V – or making negative.
Finally, the power supply must be connected to the mains (Phase, neutral and Earth) 220VAC.
