What are the components of LED strips?

LED Strips are composed of many parts, such as lamp beads, wires, resistors and others. Generally speaking, each roll of high-voltage LED Strip is 100 meters, and the low-voltage led strip is mostly 5 meters. Before we go to buy, we can measure the size we need, and then let the merchant cut it for you.
LED strip light is a more advanced cold light source. It does not radiate a lot of infrared and ultraviolet rays like incandescent lamps and fluorescent lamps. It has almost no current heating effect like incandescent lamps, and it will not be affected by thermal expansion and contraction. This can cause explosion. It will not cause yellowing of bulbs, will not accelerate the aging of lamps, and will not cause a greenhouse effect on the surrounding environment.
Different led light strip manufacturers have different specifications of led light strips, so you must pay attention when choosing. The specification mainly refers to the number of lamp beads per meter. For example, 72 means that there are 72 lamp beads per meter. You can choose according to your needs and hobbies. The type of lamp beads and the number of lamp beads per meter determine the price of the led strip.
Usually a group of 3 led lamp beads, if it is 50 lights, it will become a group with insufficient quantity, but if it becomes a group of two led lamp beads, the resistance value of the current limiting resistor will be increased, which will cause resource waste. Therefore, when making LED light strips customized for special requirements, we must pay attention to the fact that the number of lamp beads is a multiple of 3, so as not to cause a waste of voltage resources.
In addition to the leakage and short circuit of the printed board of the led light bar and the metal part on the back of the light bar, the method of changing the light bead can be adopted for a single or multiple led light bead short circuit or open circuit, but the premise is that the same method must be used. The type of lamp bead requires operating experience and operating tools. The operating tools are soldering stations and air guns. If you use an ordinary soldering iron to solder, the pins at both ends of the led lamp bead are welded, but the heat dissipation on the back of the led lamp bead is not soldered, and the service life of the lamp bead will not be long, because the life of the led strip light depends on the temperature.
