Why we take lower voltage strips?

LED strips are divided into high-voltage strips and low-voltage strips according to voltage.
The voltage of the high-voltage LED light strip is: 220v, which is the usual household voltage. Also called AC light strip.
The voltage of low-voltage LED strips is: 12V and 24V, in addition to 3V, 36V and other low-voltage designs, also called DC strips.
The high-voltage LED light strip works with a voltage of 220v, which is a dangerous voltage and is suitable for use in places that are not accessible to the human body. The installation of high-voltage light strips is relatively simple compared to low-voltage light strips. It can be directly driven by a high-voltage driver and connected to a household power supply. High-voltage LED light strips can usually carry a power supply of 30-50 meters. During use, due to The voltage is high, and the heat per unit length is much more than that of low-voltage LED strips, which directly affects the life of high-voltage strips. Generally speaking, the service life of high-voltage strips is about 10,000 hours.
Low-voltage LED light strips are safe voltages under the operation of DC voltage, and are harmless to human body contact, and can be used in a variety of occasions.
Such as home decoration, outdoor building lighting, shopping mall atmosphere lighting design, landscape lighting design, parks, roads, bridges and other lighting designs can be preferred low-voltage LED strips.
Low-voltage LED strips, because they use DC power supply, the length of the strips is generally 5 meters, 10 meters, there will be a certain voltage drop beyond this length, currently using the ic constant current design, the longest connection length of the low-voltage LED strips can be up to 15-30 meters.
The low-voltage LED strip has good heat dissipation performance and small light decay, and its 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 practical applications, light strips can be purchased according to the actual application.
