This supervision and spot check is based on GB 16844-2008 "Safety requirements for self-ballasted lamps for general lighting", GB 17625.1-2012 "Electromagnetic compatibility limit harmonic current emission limit (device phase input current 16A)", GB 17743- 2007 "Limitations of Radio Disturbance Characteristics of Electrical Lighting and Similar Equipment" The results of quality supervision and inspection of self-ballasted fluorescent lamps for general lighting in Shanghai released by Shanghai Quality and Technical Supervision Bureau in 2016 show that there are 2 batches of 18 batches of tested samples. The second time failed. This supervision and spot check is based on GB 16844-2008 "Safety requirements for self-ballasted lamps for general lighting", GB 17625.1-2012 "Electromagnetic compatibility limit harmonic current emission limit (device phase input current 16A)", GB 17743- 2007 "Limitations and Measurement Methods for Radio Disturbance Characteristics of Electrical Lighting and Similar Equipment", relevant laws and regulations, departmental rules and regulations, current and effective corporate standards and product express quality requirements. The following items of the product were tested: interchangeability, protection against electric shock, mechanical strength, heat resistance, fire and flame resistance, fault conditions, harmonic current limits, disturbance voltage, and radiated electromagnetic disturbance. The spot check found that Jiangsu Haomai Lighting Technology Co., Ltd. produced (nominal) 1 batch of spiral energy-saving lamp disturbance voltage project failed; Zhejiang Keguang Lighting Technology Co., Ltd. produced (nominal) 1 batch of Keguang lighting energy-saving lamps Harmonic current limit and disturbance voltage items failed. It is understood that because the lamps commonly use electronic ballasts and electronic transformers as the main control device, the electronic products that fail the power terminal disturbance voltage project will generate high-frequency harmonic signals during operation. These high-frequency signals pass through the power terminals. The transmission of the power grid will bring electromagnetic pollution and harass the normal operation of the surrounding electronic equipment. Seriously, it may also have adverse effects on the safe operation of the power grid and human health. Consumers should pay attention to the purchase of famous brand products produced by well-known enterprises when purchasing lamps; the product logo should be checked when purchasing. The specifications, models and trademarks of the products should be consistent with the instructions. There should be a national compulsory certification mark on the product manual or nameplate. That is, the CCC mark), the name of the manufacturer, the factory inspection certificate, and the execution standard code.
Coherence Laser
Long coherent Laser features with the characteristic of long coherence length >1 m, are ideal for application in holography, photoetching interference, DNA sequencing, flow cytometry, digital imaging, analytical chemistry, particle measurement, confocal microscopy, Raman spectroscopy and many other fields. Housed in ultra compact package, these lasers are the perfect choice for OEM instrumentation, systems design and integration, and also for end user applications in research and development.
