The difference between low-voltage LED strips and high-voltage strips

Common lamps on the market have high-voltage LED strips and low-voltage LED strips. High-voltage LED strips are also called AC strips, and low-voltage LED strips are also called DC strips. What are the differences between these two flexible LED lights? How to choose the advantages and disadvantages between the players?

Installation: The installation of the high-voltage LED light bar is relatively simple. It can be directly driven by a high-voltage driver. Generally, it can be configured directly in the factory, and it can work normally after turning on the 220V power supply. The installation of the low-voltage LED flexible light strip requires the installation of a DC power supply in front of the light strip, which is relatively complicated during installation.

Safety: The 220V voltage used by the high-voltage LED strips is dangerous, and there are potential safety hazards in some risky applications; the low-voltage LED strips work under a DC 12V working voltage, which is a safe voltage and can be used in various occasions , There is no danger to the human body.

Packaging: The packaging of high-voltage LED strips and low-voltage LED strips are also very different. High-voltage LED flexible strips can generally be 50-100 meters per roll; low-voltage LED strips generally can be up to 5-10 meters per roll; beyond The attenuation of DC power supply above 10 meters will be very severe.

Price: If you look at the two types of lights alone, the price of the LED strip is similar, but the overall cost is different, because the high-voltage LED strip is equipped with a high-voltage power supply, generally a power supply can carry 30~50 meters LED flexible light bar, and relatively speaking, the cost of high voltage voltage is relatively low. Low-voltage LED strips need to be equipped with a DC power supply. Generally, the power of a 1 meter 60-bead 5050 strip is roughly 11~14W, which means that each meter of the strip needs to be equipped with a DC power supply of about 15W. The cost will increase a lot, which is much higher than the high-voltage LED strip. Therefore, from the overall cost point of view, the price of low-voltage LED lamps is higher than that of high-voltage LED lamps.

Service life: Technically, the service life of low-voltage LED strips will be 50000-100100 hours, but the actual use can also reach 30000-50010 hours. Because of the high voltage, high-voltage LED strips generate much more heat per unit length than low-voltage LED strips, which directly affects the life of high-voltage LED strips. Generally speaking, the service life of high-voltage LED strips is about 10,000 hours.

LED light strips are often used to outline the outlines of various buildings, construct large-scale lighting patterns, various indoor and outdoor decorations, residential and home beautification and other lighting decorations. According to the differences in the use of LED strips and the different requirements for the strips, the analysis shows that high and low voltage LED strips have their own advantages and disadvantages, and users need to make a reasonable choice according to their different use environments.
