Under the interpretation of CCC Tekken LED driver certification standard
Core tip: over the years, the vigorous development of LED industry, in addition to the state's strong support for new energy and energy saving technology, but also inseparable from the LED lighting as a career to manage, with life in the struggle forced LED practitioners.
We are looking for a mandatory national standard issued, to guide and regulate the competition has been fully LED industry, on the other hand the national standard after the implementation of “ &rdquo and “ pain; forced shuffle ” terrified! So, from now on, starting from the LED drive manufacturers, we should fully face the guiding significance and guiding role of national standards in business activities. Under the premise of meeting the national standard, we should seriously plan product lines, adjust business strategies, and try not to pull the thigh of the state and industry.
Certification background
China National Certification and Accreditation Administration 2014-07-16 issued the "Compulsory Product Certification Implementation Rules lighting appliances" Number: CNCA-C10-01:2014. Since September 1, 2014, it will be enforced from September 1, 2015, that is, many LED drivers and lamps manufacturers have only 1 years of buffer period.
LED drive power supplyPrior to 2014, it belongs to the category of CQC voluntary certification. Now included in the 3C certification list, “ lighting appliances category — — ballast type ” item increase “ LED module with DC or AC electronic control device ” products, which is very significant.
Implementation standards
The "rules for the implementation of the twelfth &ldquo lighting" mandatory product certification; with DC or AC electronic control device &rdquo module LED; as LED drive power (the following are as LED module with DC or AC electronic control device for short) of the certification basis, it performs the standard respectively:
Safety standard:
1）GB 19510.1 -2009 /IEC61347-1:2007
Control devices for lamps: first parts: General requirements and safety requirements;
2）GB 19510.14 -2009 / IEC61347-2-13:2006
Control devices for lamps: Part fourteenth: Particular requirements for DC or AC electronic control devices for LED modules.
EMC standard:
1）GB17743-2007 / CISPR 15 :2005
Limits and measurement methods for radio disturbance characteristics of electrical lighting and similar equipment;
2）GB17625.1 -2003 / IEC61000-3-2:2001
Electromagnetic compatibility limits harmonic current emission limits (device input current per phase ≤ 16A).

Read through the above 4 standards, comb out the following content, for your reference. There are different places to understand and criticize.
1, LED non isolation drive power is not in the "LED module with DC or AC electronic control device" certification range.
The above two safety standards have repeatedly emphasized the safety of LED drive power supply. The parameters such as creepage distance, dielectric strength and electrical clearance are based on “ the isolated power supply &rdquo is the premise.
LED non isolation drive power, if you want to obtain 3C certification, may only be used as part of the lamp, with the whole lamp to apply (not verified).
2, LED isolation drive power supply design should pay attention to technical indicators:
① Independent drive power must meet the requirements of classification and marking in GB7000.1-2007; the bare panel type drive power must meet the lighting standards in GB7000.1-2007.
② Insulation strength: the insulation resistance requirement of basic insulation is not less than 2MΩ the insulation resistance requirement of double insulation and strengthened insulation is not less than 4MΩ.
③ The components that must be tested for insulation strength are:
a）Between separate and separated live parts with different polarities;
b）Between charged parts and external components (including positioning screws);
c）Between the charged parts and the corresponding control terminals.
④ Withstand voltage test: see table below

⑥ Independent safety extra low voltage DC or AC electronic control device when the terminals exposed by LED module, with the maximum output voltage when the load does not exceed 25V, the no-load voltage effective value is less than 33V, and the peak voltage does not exceed 33√ 2; control device rated output voltage of more than 25V to install insulated terminals.
⑦ LED isolation drive power to withstand 1 hours of open circuit, short circuit, over-current test.
⑧ Sign: specify the input (PRI), output (SEC) and other nameplate information expression method.
⑨ Temperature rise test: it's a little tedious. See the standard file!
⑩ EMC electromagnetic compatibility and radiation indicators, terms are too boring to list, on the implementation of the standard of more technical specifications, please inquire the relevant standards to obtain, not here one by one list.
3、LED drive power design stage key components selection link should pay attention to the supplier's product certification and supply capacity, so as to avoid product type test passed, inspection plant and production links to find the key material in and out, waiting to be BOSS curse it!
4、In LED module DC or AC electronic control device, the power factor, conversion efficiency, starting time and product design life of LED drive power supply are not involved. Now is the implementation of the outdated GB/T24825-2009 LED "performance requirements for Modular DC or AC electronic control devices"
5、Has received CQC certification for LED drive power, proposal to 3C certification in September 1, 2014. Transfer fee I said is not, detailed inquiry agencies.
6、Product certification is passed, only the product to the market the first step, to ensure that batch production and delivery of type test sample consistency is the responsibility and conscience of the enterprise!
