LED courtyard lamp power supply system is different from the traditional light source, LED by realizing the constant current drive power, is to guarantee the normal work of a large foundation, a simple scheme of switch power supply damage often a LED device. How tightly compressed together a group of the LED safety, also is an indicator of investigation LED garden light. LED to the requirement of the drive circuit is can ensure constant current output characteristics, because the LED forward junction voltage relative changes at work area is very small, so to ensure the LED drive current constant is basic guarantee for the LED constant power output. For our country the status quo of the power supply voltage is not stable, courtyard lamp drive circuit with constant current output characteristics of LED lamps and lanterns is very necessary, can ensure constant and prevent the super power of the LED light output. LED lighting at present in China is comparatively mature technology, the reliability of the LED garden light use been improved greatly, and the industry of advanced street lamp manufacturers, such as lighting, which USES up to the standard lighting LED garden light. In relatively nervous energy today, garden LED lights can be a lot of energy, energy saving also provide people with lighting, lighting the LED garden light has a very strong potential replication.
