With the rapid development of China's real estate market, civil home lighting is becoming more sophisticated and mature after continuous market cultivation, and home lighting demand shows a trend of rapid growth. Electromagnetic compatibility problems associated with the high growth of luminaire products have also caused electromagnetic pollution problems to the environment. Electromagnetic pollution, water pollution, and air pollution are known as the three major sources of pollution in today's society.
Relevant standards for electromagnetic compatibility testing of lamps: CISPR 15 corresponds to national standard GB17743, EN 55015
Radio disturbances in electrical lighting and similar equipment are specified in CISPR 15, which mainly correspond to the following three indicators:
1" insertion loss;
The measurement frequency for insertion loss ranges from 150KHz to 1605KHz, and its calculation formula is 20lg(U1/U2)dB, where U1 and U2 are input voltage and output voltage, respectively.
The measuring equipment is as follows:
2" disturbance voltage;
The disturbance voltage is divided into the voltage measurement of the power terminal (9KHz-30MHz) and the voltage measurement of the load and control terminals (150KHz-30MHz)
The measuring equipment is as follows:
3" electromagnetic radiation disturbance
The electromagnetic radiation disturbance is measured at a frequency range of 9 kHz to 30 MHz, and the radiation antenna is received and measured by a loop antenna.
The measuring equipment is as follows:
Piezo Transducer,Piezo Audio Transducer,Piezoceramic Transducer,Piezo Pressure Transducer
