LED manufacturers export Europe and the United States LED standards and certification

Talking about LED standards, it said to Chinese manufacturers that the high technology and safety standards in Europe and the United States are invisible technical trade barriers. The industry believes that the domestic LED lighting industry to break these technical barriers to overseas markets, you first need to understand the European and American LED standards for LED lighting products, safety, electromagnetic compatibility, performance and other requirements.

I. European and American Standards Institutions and Certification Marks ANSI: The American National Standards Institute is a voluntary organization of companies, governments, and other members. It rarely stipulates standards. ANSI standards are used voluntarily, but they are legalized. References and standards set by government agencies are generally mandatory standards.

UL: It is the abbreviation of Underwriter Laboratories Inc. The UL Safety Test Institute is the most authoritative in the United States and it is also a large private institution engaged in safety testing and identification in the world.

FCC: The Federal Communications Commission is an independent agency of the U.S. government and is directly accountable to Congress. The FCC coordinates domestic and international communications by controlling radio broadcasting, television, telecommunications, satellites, and cables.

ETL: ETL is short for Electrical Testing Laboratories. The ETL Laboratory was founded by American inventor Edison in 1896 and enjoys a high reputation in the United States and worldwide. The "us" in the lower right indicates that it applies to the United States, the lower left "c" indicates that it applies to Canada, and the terms "us" and "c" apply to both countries.

EnergyStar: Energy Star, an energy conservation program led by the U.S. government that focuses on consumer electronics, was launched by the US Environmental Protection Agency (EPA) in 1992 to reduce energy consumption and Reduce greenhouse gas emissions from power plants.

IEC: The International Electrotechnical Commission is the world’s first established international electrotechnical standardization agency. It is responsible for the international standardization work in the fields of electrical engineering and electronic engineering. Nearly 100,000 experts from around the world participate in the standardization of IEC standards. Revision work.

ENEC: (EuropeanNormsElectricalCertification, European Standard Electrical Approval) is a generic European standard used for specific and European-compliant products (such as lighting equipment, components, and office & data equipment), the ENEC mark is a universal mark of European safety certification, 2000 The "ENEC" logo, which was originally allowed only by European manufacturers, began to be used by all manufacturers worldwide.

GB: The Chinese Pinyin abbreviation of “National Standard” is composed of the code of the national standard, the serial number issued by the national standard, and the year number issued by the national standard (the last two digits of the year of release are adopted), which are compiled by the standardization administrative department of the State Council. Released by the National Standardization Competent Authority to release uniform standards across the country.

CCC: China Compulsory Certification. The compulsory product certification system began on December 3, 2001. The original "CCIB" certification and "Great Wall CCEE certification" were unified as "China Compulsory Certification". Its English abbreviation is " "CCC", abbreviated as "3C" certification, its product catalog contains 19 major categories and 132 kinds of products. The products in the catalog must be certified by a nationally-accredited certification body. After obtaining relevant certificates and applying certification marks, they can leave the factory and import. Sales and use in business services.

Second, the export of LED products to the EU market standards EU countries need to pass through the safety certification test (LVD) and electromagnetic compatibility certification test (EMC), the main certification marks CE and ENEC, certification reference standards mainly include: IEC/EN : 60598-1 (General Requirements and Tests for Luminaires), IEC/EN: 60598-2-3 (Safety Requirements for Road and Street Lighting Fixtures), IEC/EN62031 (General Safety Requirements for LED Modules) IEC/EN: 61000-3 -2 (single-phase input current ≤ 16A equipment harmonic current emission limit), IEC/EN: 61000-3-3 (Voltage fluctuations and flicker limits in low-voltage power supply systems), IEC/EN61547 (General lighting equipment electromagnetics Compatible with Immunity Requirements), IEC/EN55015 (Limits and Measurement Methods for Radio Disturbance Characteristics of Electrical Lighting or Type Equipment), CE certification and ENEC certification are basically the same, but there are significant differences in certification. The main performance is as follows:

1. ENEC must be tested and certified by ENEC member certification bodies. CE is a self-proclaimed certification. If the company believes that its products have met the CE certification standards, it does not require third-party testing and certification. ;

2. ENEC certification, the manufacturer's product management must comply with ISO9002, or its equivalent standard, CE certification does not require ISO-related standards;

3. The ENEC certification requires that according to the harmonization inspection procedure, the initial and minimum annual output will be subject to inspection by the issuing authority, and CE-certified products do not require inspection by the relevant certification body;

4. ENEC certification requires selective retesting of certified products every other year, and requires retesting costs. CE certified products are continuously effective when the product has not changed;

5. ENEC adopts the "Standard European Committee for Standardization (EN)" standard and the CE adopts the "International Electrotechnical Commission (IEC)" standard, but the contents of the two standards are exactly the same;

6. ENEC certification, if the power supply is purchased, the power supply must pass ENEC certification, and then use the power supply as a lamp for certification testing. If the power supply is the applicant's own production, you can not need ENEC certification, but need to cooperate with the lamp to do random test, reference standards For EN61347-1 (General Requirements and Safety Requirements for Lamp Control Devices), EN61347-2-13 (Special Requirements for Control of AC or DC Electronic Devices with LED Modules), CE Certified Power Supply, if CE Marked, Only Test Power Supply With the EMC test of the lamps, the power supply is no longer subjected to random safety tests.

Third, the export of LED products to the North American market The main certification of the North American market is UL, ETL, FCC and ENERGY STAR (Energy Star), etc. LED road lighting products UL certification quoted UL8750 or UL60950, UL1598 two standards, do not test The EMC characteristics of the luminaire, ETL certification test quote exactly the same as the UL standard. FCC certification quoted FCCPart15B, ClassAdigitaldevice test limit standards, does not test the safety characteristics of lamps; ENERGYSTAT (EnergyStar) mainly for residential areas and commercial lighting class LED lamps and optical performance requirements, LED road lighting temporarily not listed; here Introduce and analyze the more common UL and FCC certifications:

U.S. laws and regulations for compulsory certification of electronic products always include Title1 to Title50, of which Title47 is a teletype video product. There are a total of Part0 to Part499, in which Part0 to Part199 are FCC. FCC certification is divided into Verification (self-certification), Declaration of Conformity (announcement declaration) and Certification (certification) three modes, using Verification, there is no test laboratory requirements, can not test (as long as the product can meet the corresponding Technical requirements) and do not need to provide information to the FCC; when using the Declaration of Conformity, test laboratories must obtain NVLAP, A2LA qualification or FCC-certified laboratories, and need multilateral mutual recognition agreements, but do not need to provide information to the FCC; use Certification The test lab is required to register on the FCC website and is officially approved by the FCC. The TCB designated by the FCC or the FCC will issue the certificate, and it will need to provide information to the FCC and obtain an FCC ID. Which authentication method to use depends on the type of product. The standard for FCC testing of LED lighting products is FCC Part15B. The certification type is: Verification.

The FCC is a mandatory certification for the EMI characteristics limits of teletype video products stipulated by the U.S. federal law. The FCC certification test of LED lamps and the EMC certification test in the EU CE are quite different. The main performance is as follows:

1. The FCC certification of LED lamps only tests EMI (radio disturbance) and does not include EMS (radio immunity) test items; in the EMC testing of CE, both require certification testing;

2. The FCC certification of LED lamps and lanterns is divided into Class A (LED lamps used in industrial and commercial environments) and Class B (LED lamps used in residential environments). The test limits of the two types are completely different. The radio in CE certification is not the same. There is only one harassment test limit standard, and the limit value is equivalent to Class B in the FCC;

3, FCC certification of LED lamps conducted harassment scan test frequency from 0.15MHz to 30MHz end, the CE certification of conducted disturbance scan test frequency from 9KHz to 30MH end;

4, FCC certification of LED lamps space radiation disturbance test frequency from 30MHz to 1GHz end, CE certification space radiation disturbance scan test frequency from 30KHz to 300MH end;

5, FCC certification requirements are more stringent, the EMI certification test limit standards usually require more than 6dB margin, CE certification EMI test margin at 3dB or more (including the read-point margin) can be;

UL certification in the United States is a non-mandatory certification, mainly for product safety performance testing and certification, and its scope of certification does not include EMC (electromagnetic compatibility) characteristics of the product. The following briefly describes the LED road lighting products involved UL8750, UL1310 and UL60950. The UL8750 is suitable for minimum safety requirements for LED lighting source components that are to be installed in non-hazardous locations rated 600V or lower, and also suitable for minimum safety of LED sources that are connected to isolated (no effectively connected) power sources such as batteries and fuel cells. Requirements; UL1310 is suitable for applications that include input voltages of 120 or 240Vac voltages via software or plug-in connection to a 15 or 20A AC branch circuit or potentially less than 150V ground, using insulated transformers and DC or AC energy sources that can be incorporated into rectifiers and other components It is expected that it can be used to provide energy for low-voltage power-operated CLASS2 power supplies; UL60950 is applicable to safety standards for information technology (IT) equipment, including mobile phones, computers and peripherals such as projectors, printers, etc. Including output power supply with LPS (Limited Power Supply) safety loop;

In the UL certification of LED lighting products, UL1310 or UL60950 can be used to test the driver power supply. The main differences between the two standards are as follows:

1. UL1310 is a CLASS II (power supply with limited voltage and capacity) power supply equipment safety standards. When the UL1310-certified power supply is a CLASS II power supply, and CLASSII power supply is used as a cUL (Canada market) LED lighting fixture certification, relevant safety tests can be exempted. UL60950 is a safety standard for information technology (IT) equipment, and its applicable certification scope is greater than UL1310, but when using a UL60950-certified power source for cUL (Canadian market certification) LED lighting fixture certification, safety testing cannot be exempted. ;

2. The UL1310 standard stipulates that the maximum output voltage (including no load) of the output voltage at the output voltage under any load condition is 42.4V. When the device does not contain the maximum output volt-ampere, the output voltage of the power-off device in the output circuit is not more than 100 volt-ampere; UL60950 defines the voltage between any two accessible circuit components under normal output voltage conditions, or the voltage between any accessible circuit component and the protective earth terminal of a Class I device, not exceeding 42.4V AC peak, or 60V DC

3, UL1310 certification applies only to 120 or 240Vac calibration voltage in the power grid CLASSII power supply equipment, UL60950 for rated input voltage does not exceed 600Vac of information technology products, for 277V voltage system UL certification of LED lighting products, power supply, can only Reference UL60950 standard certification test.
