Low-voltage AC lighting systems are becoming more and more popular in the market, from indoor accent lighting to general track lights, and even to outdoor lighting systems. Retailers and home building materials such as IKEA and Home Depot have quickly and widely communicated these technologies to customers, allowing the power system to incorporate specific low-voltage usage rules so that users can install without having to go through a contractor.

The rise of low voltage AC LED lighting applications
All low-voltage AC lighting systems use a stand-alone mains supply that provides off-line AC conversion to a low voltage solution that will not exceed 30 volts at any load, even if the circuit is open. Valid value (VRMS). Second, in all cases, the circuit must have a current limit of 25 amps (A), which will determine the maximum power for low voltage AC lighting applications. The typical output voltage is 12 or 24 volts alternating current (VAC), but the maximum current value of 25 amps must be maintained, whether it is a 12 volt, 300 watt (W) system or a 24 volt 600 watt system.
For the above reasons, low-voltage AC lighting is favored in light-emitting diode (LED) lighting applications, and the technology can even be applied to 300 watts of LED lighting power, equivalent to three to four street lights. This gives the designer a great deal of flexibility in design, allowing for a relatively large single component or a multi-configuration lamp design from a single power supply, or a design between the two. What is certain is that the flexible LED lighting application design will make the lighting system move forward from traditional incandescent lamps.
In a low-voltage AC system, three different lighting fixtures can be considered. First, a large/high output design is installed in only one or two individual systems; secondly, ten to twenty devices can be supported in the system small light source. Medium-sized output design; and finally, a small output design that allows for fifty to one hundred illuminators in a single system.
Large array design for high light source output applications
In the case of large array designs, the benefits of LED unique design can be immediately demonstrated in two different ranges, especially in the case of more unique large lighting sources, which can create high light source output applications through large arrays. . In general, a 100-watt LED source is used in streetlight applications (using a high-voltage offline solution), although it is not recommended to use a low-voltage AC system (which brings new rules and standards). But the designer has the opportunity to achieve the same effect with a low-voltage AC budget, starting with a 3.5 volt forward voltage and a standard LED using 350 mA, roughly 1.2 watts or about 80 LED based.
