LED light strips were born with the development of LED technology in recent years. When there are no LED light strips, T4 and T5 lamps are used for backlighting, but T4 and T5 lamps are used for backlighting. The Z minimum size of the lamp tube is 0.3 meters, which means that if there is less than 0.3 meters, a dark area will be left, while the LED light strips emit light evenly, and can be cut according to the actual length, which is very convenient. Green, blue, yellow, white, warm white, etc. so many light colors are available, and there are even colorful changes. Now basically T4 and T5 tubes are rarely used, and LED light strips are used instead!
1. About LED strips
As shown in the picture above, this is the true face of the LED light strip, just like a belt, plus the LED is used as the name suggests, called LED light strip, directly connected to the 220V mains power can be lit, fixed with a fixed card, It's not difficult to use.
2. The luminous color of the LED strip
The luminous color of the LED strip is actually the luminous color of the LED light. As described above, LED lights have red, yellow, blue, green, positive white, warm white and other monochromatic lights, and there are also colorful changes. Generally, warm white light is used in most homes, because it can create a very warm atmosphere.
3. Commonly used types
3528 LED strip and 5050 LED strip
At present, the commonly used types of LED strips are 3528 and 5050 strips (3528 refers to the size of the LED light source, which is 32mm long and 28mm wide, and 5050 refers to the length and width of the LED light source that are both 50mm). The difference between the two is size. On the other hand, there are 3 LED chips in the 5050 LED strip, while there is only 1 LED chip in the 3528 LED strip. Therefore, under the same number of LED strips, the brightness of the 5050 LED strip is 3 times that of the 3528 LED strip, and the power is also 3 times that of the 3528 LED strip. times, the price is also more expensive.
Regarding power consumption, this involves the issue of electricity bills, and many users are very concerned about this issue. The rated power of the 3528 lamp bead is 0.06W (0.02A*3V=0.06W), while the rated power of the 5050 is 0.18W (0.02A*3V*3=0.18W), because there will be a protection resistor in the circuit. Down, according to 60 lights/meter, the power consumption of one meter of 3528 light strips is about 4W, and that of one meter of 5050 light strips is about 12W. If you install dozens of meters, the power consumption gap is still very large.
4. Structural composition and installation matters
The structure of the led strip includes lamp beads, circuit boards, wires, glue, resistors and related accessories.
LED light strips are generally 100 meters in a roll. When purchasing, you need to order how much according to the length you need. These should be told to the seller in advance, and they will usually be cut for you. There are several sections at home, and each section is equipped with a connector, which can be directly plugged into the socket. If you want to cut by yourself, you need to pay attention that the light strip is usually marked with a special scissors mouth, cut it at the scissors mouth, connect it, and it is ready to use.
Remember: Be sure to cut according to the instructions, otherwise it will cause no light!
There are accessories for the light strip. The accessories generally include a plug (that is, the power supply), a pin (for connection), a fixing card (a plastic clip for fixing the light strip) and a tail plug (a plastic sleeve to protect the tail of the light strip). These accessories Generally, merchants will have delivery, but you need to negotiate with the merchant first, so that you don't have less.
5. Actual installation
Cut according to the actual length of the light trough at home, assemble it, test it, and then you can install it, fix it with the light strip clip, and then turn on the power supply, and the light strip will turn on. If you don't want to install it yourself, you can hand it over to the decorator after you buy it, it's a piece of cake!
6. About quality and safety
LED light strips are generally high voltage 220V, so they are wrapped with a thick layer of flame retardant glue. Wires, circuit boards, etc. are generally made of copper. The LED lamp beads determine the life of the light strip. For the sake of electricity safety , You must not choose the inferior quality because of the cheap price, and it may be a safety hazard in exchange!
