The main purpose of LED flood light fixtures should be against over current. First, the purpose of protecting personal property security. Usually in power input voltage relatively high programs often for the purpose of increasing devices. Second, subsystem and external system partition whose external system instability affects the security subsystem. However, the subsystem within device damage, as devices appears short circuit fault mode.
Or due to external factors that lead to internal security insulation level is damaged. Resulting in internal circuit to ground short circuit. If there is no hedging action and outside system sharing and do not take effective measures on time such as by this led flood light fixtures will result in the external system of the action insurance system that will lead to the entire system power outage. And this in important places as hospital causes indirect loss and may also cause loss.
So sometimes you have to add 2 fuses to the input side of the power supply. Third purpose of led flood light fixtures is to protect important and valuable electronic components or devices. For LED lighting, the cost of flood light beads accounted for the bulk of the cost of the entire lamp. In non-insulated type of motor or non-constant power-driven circuit, you must run the output end of the necessary over current protection.
