Electromagnetic Compatibility (EMC) refers to the ability of electronic devices to operate normally in an electromagnetic environment without causing interference to other devices. In modern electronic equipment, electromagnetic compatibility has become a crucial performance indicator.

 

What Are the EMC Test Items for Lighting Fixtures?(图1)


The main EMC test items for lighting fixtures include:

- Conducted Emission Test (CE)

- radiated emission test (RE)

- Harmonic Current Test (Harmonic)

- Voltage Fluctuation and Flicker Test (Flicker)

- Electrostatic Discharge Immunity Test (ESD)

- Radiated Immunity Test (RS)

- Power Frequency Magnetic Field Immunity Test (PFMF)

- Electrical Fast Transient/Burst Immunity Test (EFT)

- Conducted Immunity Test (CS)

- Surge Immunity Test (Surge)

- Voltage Dips and Interruptions Test (DISP)

 

China’s JJR Laboratory is equipped with professional electromagnetic compatibility equipment and can provide high-standard testing services for customers. Let’s now explore EMI testing.

 

Electromagnetic Interference (EMI) refers to the interference that electronic devices may cause to other equipment or themselves during operation. It mainly consists of two forms: conducted interference and radiated interference. Below is an explanation of EMI and its testing methods:

 

- Conducted Interference Test: Conducted interference tests for LED lighting fixtures typically include a series of tests ranging from low to high frequencies. The FCC certification testing frequency range is from 0.15 MHz to 30 MHz, while the CE certification testing frequency range is from 9 kHz to 30 MHz.

- Radiated Interference Test: Radiated interference tests evaluate the ability of the equipment to transmit interference signals through space. The FCC and CE certification radiated interference testing frequency range is from 30 MHz to 1 GHz.

 

Importance of emc testing

EMC testing is an important means to ensure that electronic and electrical equipment operates normally in an electromagnetic environment and does not interfere with other equipment. Lighting equipment, especially LED lighting, is also subject to stringent EMC testing requirements, such as the FCC certification in the United States and CE certification in the European Union.
