This is the true face of the LED light band, just like the band, plus the use of LED light source (about the LED light source, no more details), as the name suggests, called the LED light band, directly connected to the 220 V mains power can be lit, fixed with a fixed card, it is not difficult to use.

In recent years, LED strip was born with the development of LED technology. When there is no LED strip, T4 and T5 tubes are used for backlight. However, the small size of T4 and T5 tubes is 0.3m, which means that if there is less than 0.3m, dark area will be left. The LED strip can emit light evenly, and can be cut according to the actual length, which is very convenient. In addition, red, green, blue, yellow, white, white, etc Warm white and so on so many light colors to choose, and even seven color changes, now basically rarely use T4, T5 tube, changed to use LED light with!

 

 

The luminous color of LED light is actually the luminous color of LED light. As mentioned above, LED lights with red, yellow, blue, green, white, warm white and other monochromatic light, there are also seven color changes. Generally, warm white light is used in the home, because it can create a very warm atmosphere.

 

 

At present, the commonly used types of LED light strips are 3528 and 5050 (3528 refers to the size of LED light source, 32mm in length and 28mm in width, 5050 refers to the length and width of LED light source, both 50mm). On the one hand, the two differ in size. On the other hand, there are three LED chips in 5050 lamp beads, while there is only one LED chip in 3528. Therefore, under the same number of lamp beads, The brightness of 5050 LED strip is three times that of 3528 LED strip, the power is three times that of 3528 LED strip, and the price is more expensive.

 

As for the power consumption, it involves the problem of electricity charges, and many users are very concerned about this problem. The rated power of 3528 lamp bead is 0.06w (0.02A * 3V = 0.06w), while the rated power of 5050 lamp bead is 0.18w (0.02A * 3V * 3 = 0.18w), because there will be protection resistor in the circuit. According to 60 lamps / m, the power consumption of one meter 3528 lamp belt is about 4W, and that of one meter 5050 lamp belt is about 12W. If it is installed for tens of meters, the power consumption gap is still large. However, the lamp band is mainly used to light the lamp slot, and most of them are decorative. Therefore, taking into account the factors such as power consumption and price, the 3528 LED lamp band with 60 lamps per meter is used more.

 

 

① The structure of LED lamp belt includes lamp bead, circuit board, wire, glue wrapping, resistor and related accessories.

② The LED light belt is generally 100 meters in a roll. When purchasing, you should tell the seller in advance according to the length you need and how much you order. Generally, it will help you cut it. Home to use several sections, each with a connector, directly plug in the socket on the line. If you want to cut by yourself, you need to pay attention to that the light band will be marked with a special scissors port. Cut it at the scissors port, connect it, and you can use it. Remember: must follow the instructions to cut, otherwise it will cause no light!

③ There are accessories for the light belt. The accessories generally include plug (that is, power supply), pin (for connection), fixing card (plastic clip for fixing the light belt) and tail plug (plastic sleeve for protecting the tail of the light belt). Generally, these accessories will be delivered by the merchants, but they need to negotiate with the merchants first, so as not to be less.

 

 

According to the actual length of the lamp slot at home, it can be cut, assembled and tested, and then it can be installed. Fix it with the lamp band clamp, connect the power supply, and the lamp band will be on. If you don't want to install it yourself, you can hand it in after you buy it.

 

 

LED lamp belt is usually high voltage 220 V, so it is wrapped with a thick layer of flame retardant glue. Wire and circuit board are generally made of copper. LED lamp bead determines the life of the lamp belt. For the sake of electricity safety, we must not choose the one with inferior quality because of its cheap price. If we want to get cheap for a while, it may be a potential safety hazard! Of course, can not rule out to find good quality and cheap, but this opportunity, not out of thin air!
