Procedure for the EMC EMI test on LED flood lights
The following stages are commonly included in the method for conducting EMC and EMI tests on LED flood lights: Obtain a sample of the LED flood light as well as the necessary testing equipment, such as an electromagnetic interference (EMI) receiver, a near-field probe, a far-field antenna, a line impedance stabilization network (LISN), a current probe, a power amplifier, and a dummy load. This is the first step in the preparation process. Prepare the testing apparatus by: Establish a connection between the EMI receiver and the LISN. After that, establish a connection between the sample LED flood light and the dummy load. Test for radiated emission by positioning a sample LED flood light on the turntable and using the far-field antenna to measure the radiated emission in a variety of directions and at a range of frequencies. Conduct a test of the conducted emission by connecting the current probe to the LED flood light, and then using the EMI receiver to measure the conducted em
