Why are low-voltage light strips preferred for LED 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. Also called AC light strip.

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

High-voltage LED light strips operate at a voltage of 220v, which is a dangerous voltage and is suitable for use in places that are out of reach of the human body. The installation of high-voltage light strips is simpler than that of low-voltage light strips. It can be driven directly by a high-voltage driver and connected to a household power supply. High-voltage LED light strips can usually be carried 30-50 meters with one power supply. During use, due to The high voltage generates much more heat per unit length than low-voltage LED light strips, which directly affects the life of high-voltage light strips. Generally speaking, the service life of high-voltage light strips is about 10,000 hours.

Low-voltage LED light strips, when working with DC voltage, are safe voltages and are harmless to human body contact, and can be used in a variety of situations.

For example, home decoration, outdoor building lighting, shopping mall atmosphere lighting design, landscape lighting design, parks, roads, bridges and other lighting designs can all use low-voltage LED light strips.

Low-voltage LED light strips use DC power supply, and the length of the light strips is generally 5 meters or 10 meters. There will be a certain voltage drop beyond this length. Currently, IC constant current design is used, and the longest connection length of low-voltage LED light strips can be Up to 15-30 meters.

Low-voltage LED light strips have good heat dissipation performance, small light attenuation, and a service life of up to 30,000-50,000 hours.

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