How much do you know about LED lights?
1. About LED strips
In recent years, with the development and birth of LED technology, in the absence of LED light strips, T4 and T5 lights are used for backlighting, but the smallest size of T4 and T5 lights is 0.3 meters. This means that if there is less than 0.3 meters, there will be a dark area, and the LED light strip will emit light evenly, and it can be cut according to the actual length, which is very convenient, plus red, green, blue, yellow, white, warm There are so many light colors to choose from, and there are even colorful changes. Now basically T4 and T5 tubes are rarely used, and LED light strips are used instead!
2. The luminous color of the LED light strip
The luminous color of the LED light strip is actually the luminous color of the LED light. LED lights have red, yellow, blue, green, positive white, warm white and other monochromatic lights, and also have colorful changes. In general, warm white light is mostly used in the home, because it can create a very warm atmosphere.
3. Commonly used types
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 light beads, while there is only one LED chip in the 3528. Therefore, under the same number of light beads, 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 light 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. However, the light strip is mainly used to illuminate the light trough. It has many decorative features. Therefore, taking into account factors such as power consumption and price, 3528 LED light strips with 60 lights per meter are used more.
4. Structural composition and installation matters
① The structure of the led strip includes light beads, circuit boards, wires, glue, resistors and related accessories.
②. The high voltage of the LED light strip is generally 100 meters in a roll, and the low voltage is mostly 5 meters. When purchasing, you should tell the seller in advance how much to order according to the length you need. They will usually help you cut them. If you use several sections at home, each section is equipped with a connector and plugged directly into the socket. If you want to cut it by yourself, it should be noted that the light strip is usually marked with a special scissors mouth, cut it at the scissors mouth, and it is ready to use. Remember: Be sure to cut according to the instructions, otherwise it will cause no light!
3. The light strip has accessories. 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 are generally delivered by merchants, but they need to be negotiated with the merchants first, so that there will be no shortage of them.
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 finally 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 a professional to install it after you buy it.
