As we all know, the working voltage of led flood light has two specifications, high voltage and low voltage. In actual lighting engineering applications, we often encounter the problem of how to choose the bottom. To choose a suitable led flood light, we must first understand both of them. The pros and cons of the person:
What are the advantages of low-voltage floodlights?
Low-voltage floodlights believe that everyone’s first impression is safety. That’s right. Using low-voltage power-supply led floodlights, the safety voltage of the human body is below 36V, and the working low-voltage voltage of LED floodlights is mostly 24V, so there will be no lamps. Leakage caused casualties.
In addition, low-voltage floodlights basically use a constant current drive scheme, and the lamps are turned on without flicker and have a longer service life. At the same time, the volume of the low-voltage floodlight is more compact and exquisite.
However, low-voltage floodlights have a limit on the number of serial connections, that is, the number of low-voltage lamps in series is usually small.
Let's talk about high-voltage floodlights. Most of the domestic high-voltage power is 220V. Therefore, high-voltage floodlights have extremely wide versatility, and there are more high-voltage lamps connected in series, and the installation is simpler than low-voltage floodlights.
However, the safety risks of high-voltage floodlights are extremely high, and the size of the lamps is not easy to miniaturize.
