Comparison of the advantages and disadvantages of high-voltage and low-voltage LED strips

     LED lights are often used to outline the contours of various buildings, to build large-scale lighting designs, various interior decorations , residential, home landscaping and other lighting decoration. According to the difference in the use of LED light strips and the requirements of different light strips , there are two kinds of high- voltage LED light strips and low-voltage LED light strips. High-voltage LED light strips are also called AC light strips, and low-voltage LED strips are also called DC strips. so these two LED lights with flexible What is the difference, in the end how about the advantages and disadvantages between the two, we buy, how to choose it? Please listen to Shangming Optoelectronics in detail:     

1, security: 220V voltages with high voltage LED lights employed, the voltage is dangerous, there are security risks in some occasions risk; low voltage LED light bar is operated at the operating voltage of 12V DC, are safe voltage, it can be used in various On occasions, there is no danger to the human body.

2. Installation : High-voltage LED light strips are relatively simple to install and can be driven directly by high-voltage drivers. Generally, the factory can be configured directly, and the 220V power supply can work normally. The installation of low-voltage LED flexible light strips requires the installation of a DC power supply in front of the light strips, which is relatively complicated during installation.

3 , price : If you look at from the two lights alone, LED lights with the price is almost, but the measure from the overall cost is not the same, because the high voltage LED lights with a high voltage power supply, generally a power supply can bring 30 ~ 50 meters LED flexible strips, and relatively high voltage voltage is relatively low cost. The low-voltage LED lamp with external DC power supply, generally 1 meter 60 beads 5050 lamp power is roughly 12 ~ 14W , which means that each meter lamp with about 15W DC power supply, so that low voltage LED lights with Cost of construction will increase a lot, much higher than high-voltage LED strips. Therefore, from the perspective of the overall cost, the price of low-voltage LED lamps is higher than that of high-voltage LED lamps.

4, Packing: high pressure and low pressure LED lights LED strip can also vary widely, generally with high pressure Flexible LED can be done 50 to 100 m / roll; and more generally with low voltage LED lights do 5 to 10 m / roll The DC power supply attenuation exceeding 10 meters will be very severe.

5, the service life: low-voltage technically life LED strip will be 50000-100000 hours, and actual use can also be achieved 30000-50000 hours. High-voltage LED light with high voltage, in the unit length of heat than the low-voltage LED light with a lot more, directly affect the life of high-voltage LED light, generally high-pressure life of 10,000 hours or so.

     As can be seen from the analysis Shangming Guang power, high and low bands have their own advantages and disadvantages of the LED, the user make a reasonable choice according to their different environments, do not waste resources.
