High and low pressure LED lamp with what kind of good?

High voltage LED lamp with lamp with low voltage and AC, LED lamp belt is also called DC lights, then the two LED flexible light with what difference between the advantages and disadvantages of what we, at the time of purchase, how to choose? Please listen to the details of the Shang Ming optoelectronics:

1, packing: LED packaging and high-pressure lamp with low voltage LED lamp with different pressure, LED lamp can generally do 50~100 meters / volume; low voltage LED lamp with general up to 5~10 meters / volume; DC power supply beyond 10 meters above the attenuation will be very bad.

2, security: working voltage of high voltage LED lamp with the use of the 220V, which belongs to the dangerous voltage in some applications, the risk hidden safety problems; low voltage LED lamp is working voltage DC 12V, which belongs to the safety voltage, can be used in various occasions, to people without any danger.

3, service life: low voltage LED lamp with the life of the technology will be 50000-100000 hours, and the actual use can also reach 30000-50000 hours. High voltage LED lamp with high voltage, the length of the unit on the heat than the low pressure LED lamp with a lot of direct impact on the life of the high-pressure LED lamp belt, in general, the service life of high pressure in about 10000 hours.

4, installation: high pressure LED lamp installation is relatively simple, can be directly driven by high pressure drive, the general factory can be configured directly, the power supply can be connected to the 220V normal work. The installation of low voltage LED flexible lamp belt in the front of the lamp with DC power supply, relatively speaking, the installation is relatively complex.

5, price: if a single from the two kinds of lights, LED lights with the same price, but the overall cost measure is not the same, because of the high pressure with the LED lamp with high power, a power supply can be flexible light strip, 30~50 meters and LED, relatively high voltage low cost. While the low voltage LED lamp belt to external DC power supply, power is generally 1 meters 60 beads of 5050 lights is about 12~14W, which means each meter lamp with DC power distribution to about 15W, so the cost will be low LED lights with much improved, greatly higher than the high pressure LED lamp belt. Therefore, from the overall cost point of view, the low pressure LED lamp prices higher than the high pressure LED lamp price.
