White LED strips have different shades. They are also called glow temperature. Measured in Kelvins(TO).
Shades:
- Cool White (8500K)
- White (6000K)
- White Day (4000 K)
- White Warm (2800 K)
- Super warm white (2200K)
1. Cool white (8500K) and white (6000K)
Cool white (8500K) and white (6000K) have blue tint. They resemble the light on a stormy day when there is a light drizzle. In my opinion, the light is unpleasant. For lovers of exotic things. Therefore, white and cool white tape are rarely used in room lighting.
Day white (4000 K)
The light resembles a clear summer afternoon. This is my favorite shade, the most pleasant and comfortable. Suitable for all rooms and liked by almost all people. It lifts your spirits and creates comfort.
Warm white (2800 K)
Has a yellowish tint. Reminds me of the good old incandescent lamps. The light is pleasant, soft, calming. Basically, such tapes (and lamps) are ordered by people who grew up with the warm light of incandescent lamps. Because it’s more common this way.
Super warm (2200K)
A shade with a strong yellowish tint. In my opinion, this is also from the category of exotic and special occasions.
Conclusion:
The most popular white LED strip for ceiling lighting is Daylight White (4000 K).
The voltage in the electrical network is 220 V and is variable, and the LED strip operates from a constant voltage of 12 or 24 V. Therefore, to power the strip, a power supply unit (PSU) is needed, which, depending on its type, would convert 220 V to 12 or 24.
The power supply input is connected to a 220 V network, the output is connected to an LED strip.
Connecting LED strip
It is important not to confuse a minus with a plus. The plus on the tape is usually a red wire, the minus is blue. There are also wires coming out of the power supply – minus and plus. It is necessary to connect the plus of the tape to the plus of the power supply, and the minus, respectively, to the minus.
If the polarity is reversed, the tape will not work. The colors of the wires on the power supply and the tape may be different. The tape can be connected from either end or simultaneously from both ends.
If it is necessary to connect more than 5 m of tape, then it is strictly forbidden to connect the 2nd piece of 5-meter tape to the end of the 1st 5-meter segment.
Incorrect LED strip connection
LEDs that are located further from the power supply, when incorrect connection either they will not shine at all, or they will shine dimly. And through the tracks of the tape, which is connected closer to the power supply, more current will flow than calculated, which is a negative point.
The tape will heat up, the current through the LEDs will increase when heated and will heat up the tape even more, and it will heat the LEDs even more. Those. there will be an avalanche-like increase in the temperature of the LEDs and their subsequent failure. In this case, the backlight will last very little. Therefore it is necessary to connect correctly.
Connecting LED strips from one power supply
This is a connection diagram using one power supply. Its power must correspond to the total power of the sections of tape that are connected to it. According to the diagram, the tapes to the power supply are connected in parallel, only the wire to the 2nd tape is longer than the wire to the 1st.
In the case of such a connection, the current will flow to the 2nd tape through its own separate wires, and not along the tracks of the 1st tape. The cross-section of the extension wire should be selected on the basis that a current of 15 A can pass through 1 sq. mm of copper wire.
The 2nd tape is mounted parallel to the 1st in a niche. However, if one power supply is not enough to connect the 2nd tape, you can use a little more complex circuit with several power supplies.
The advantages of this scheme are that when using several power supply units, they can be smaller in size, which will make it easier to hide them in a niche than one large one. The price will be approximately the same if you purchase one power supply with high power or several small ones with the same total power as his.
Connecting an LED strip with 2 power supplies
In this scheme, one end of the extension wire is connected to a 220 V network, the other to the power supply of the 2nd tape. Here it is enough for the cross-section of the wire to be 0.75 sq. mm. This scheme it is convenient in that it allows the use of small-sized power supplies, for which it is easy to find a place in the ceiling niche where to hide them.
White LED strip is an excellent option for organizing backlighting or lighting in the interior. On average, the luminous efficiency of LED strips is 60 Lm/W, which is approximately six times more than incandescent lamps. Thus, using a white LED strip to illuminate rooms is significantly more profitable than simple light bulbs, especially if you take into account the service life of LEDs, which can be more than ten years.
When choosing a white tape, you need to focus on the color temperature of the glow and power. For example, white LED produces light similar to the radiation of conventional incandescent lamps. White cool LED strip produces light with a high color temperature. In most cases, an intermediate option is ideal - a daytime LED strip. white.
As for the power of the white LED strip, it directly depends on the size of the diodes and the density of their arrangement. LED strips with single crystals are marked 3528, which means the housing size is 3.5 mm x 2.8 mm. These strips can have up to 120 diodes per meter in one row or 240 diodes per meter in two rows.
LED white strips labeled 5050 include three crystals per package and can have up to 60 diodes in one row. As a result, you can arrange 120 pieces in two rows. The more crystals there are per 1 meter of tape, the correspondingly higher its price.
Powerful white LED strips are often used for interior lighting. If suddenly their power is more than 15 W/meter, it is worth using a radiator in the form aluminum profile, which can have a matte or transparent screen.
In addition to color rendering and temperature power, when choosing a white LED strip, you need to pay attention to Special attention on its protection class. For simple rooms, products that have IP-33 protection are perfect, and for rooms with high humidity, such as the bathroom, requires protection of at least IP-65. To use LED strip in swimming pools and saunas, you need to use a sealed strip with a protection class of IP-68.
Areas of application of white diode tape
- Room design - decorated with ribbon stretch ceiling, arches and niches, floor lighting is made from it.
- Outdoor design - LED strips are used to highlight contours, pools, fountains, and highlight architectural elements.
- Car tuning – lighting in the trunk, headlights or interior.
- In outdoor advertising – decor and lighting advertising signs and shop windows.
- Furniture lighting – LED strip is convenient for illuminating wardrobes.
Advantages of LED strips:
- low power consumption;
- long service life;
- wide range of applications;
- ease of installation;
- safety;
- ease of use.
