Why do LED light strips prefer low-voltage light strips?

LED light strips are divided into high-voltage light strips and low-voltage light strips according to voltage.

The voltage of high-voltage LED light strips is 220v, which is the normal household voltage. It is also called AC light strips.

The voltage of low-voltage LED light strips is 12V and 24V. In addition, there are low-voltage designs such as 3V and 36V, also called DC light strips.

High-voltage LED light strips use a voltage of 220v to work, which is a dangerous voltage and is suitable for places where human body cannot touch. High-voltage light strips are simpler to install than low-voltage light strips. They can be driven directly by high-voltage drivers and connected to household power. One power supply can carry 30-50 meters of high-voltage LED light strips. During use, due to the high voltage, the heat generated per unit length is much more than that of low-voltage LED light strips, which directly affects the life of high-voltage light strips. The service life of high-voltage light strips is about 10,000 hours.

Low-voltage LED light strips, under the operation of DC voltage, are safe voltages, harmless to human body contact, and can be used in a variety of occasions.

Low-voltage LED light strips are preferred for home decoration, outdoor building lighting, shopping mall atmosphere lighting design, landscape lighting design, parks, roads, bridges and other lighting designs.

Low-voltage LED light strips are powered by DC, and the length of the light strip is generally 5 meters or 10 meters. If the length exceeds this, there will be a certain voltage drop. Currently, IC constant current design is used, and the longest connection length of low-voltage LED light strips can reach 15-30 meters. Because of its good heat dissipation performance and low light decay, the service life can be as high as 30,000-50,000 hours.

High-voltage LED light strips and low-voltage LED light strips have their own advantages and disadvantages. In actual use, you can choose the light strip according to the actual use occasion.
