lighting products

lamps exported to Europe today to LED products. Turning LED standards, the Chinese manufacturers say, Europe demanding technical and safety standards are invisible technical barriers to trade. The industry believes that the domestic LED lighting practitioners to break the technical barriers to overseas market, you first need to understand Europe and the United States LED standards LED lighting product safety, electromagnetic compatibility, performance and other requirements.

one, major U.S. and European standards bodies and certification logo

UL : is Underwriters Laboratories ( UnderwriterLaboratoriesInc. ) shorthand, UL safety test of America's most authoritative, the world engage in safety testing and identification of the larger private institutions .

FCC : Federal Communications Commission < / span> ( FederalCommunicationsCommission ) , is an independent U.S. government agency, directly accountable to Parliament. FCC control of radio, television, telecommunications, satellite and cable to coordinate domestic and international communications .

ETL : ETL electronic testing laboratory in the United States (ElectricalTestingLaboratories) short , ETL laboratory by American inventor Thomas Edison in 1896 handedly created years in the United States and around the world enjoy a high reputation. Bottom right "us" that applies to the United States, the lower left "c" that applies to Canada, but also has "us" and "c" applicable in both countries.

EnergyStar : Energy Star , is one dominated by the U.S. government, mainly for consumer electronics energy conservation plan, the Energy Star program in 1992 by the U.S. Environmental Protection Agency ( EPA ) initiated, purpose is to reduce energy consumption and reduce greenhouse gas emissions from power plants.

IEC : International Electrotechnical Commission (InternationalElectrotechnicalCommission) , is the world's oldest international electrotechnical standardization body responsible for the electrical and electronics engineering in the field of international standardization work , countries in the world with nearly 10 ten thousand experts participating in IEC the standard formulation, revision.

ENEC : (EuropeanNormsElectricalCertification ) , European standard electrical certification yes and meet European standards for specific products (such as lighting equipment, components, and office & data device) uses common European standard, ENEC European safety certification mark is a universal symbol, 2000 years Start originally allowed only European manufacturer uses "ENEC" marks the beginning of the whole open for use by all the world's manufacturers.

two, LED products exports to the EU market standards

exports to the EU countries need to include safety certification testing ( LVD ) and electromagnetic compatibility certification test ( EMC ), the main certification labeled CE and ENEC , certified reference standards include: IEC / EN :60598-1 (lamps General requirements and tests), IEC / EN :60598-2-3 (roads and street lighting safety requirements) , IEC/EN62031 (LED module general safety requirements ) IEC / EN :61000-3-2 ( single-phase input current ≤ 16A devices harmonic current emission limits ), IEC / EN :61000-3-3 ( low voltage power supply system voltage fluctuations and flicker ), IEC/EN61547 ( general lighting purposes - EMC immunity requirements ), IEC/EN55015 ( electrical lighting or type of equipment - Radio disturbance characteristics - Limits and methods of measurement ) .

three, LED products exported to North America market standard < / span>

North American market, the main export certification are UL , ETL , FCC and ENERGYSTAR (Energy Star), such as several, LED road lighting products UL certified reference < / span> UL8750 or UL60950 , UL1598 two standards do not test fixture EMC characteristics , ETL certification test is completely the same as the reference UL standards. FCC certified reference FCCPart15B, ClassAdigitaldevice standard test limits, do not test fixture security features; ENERGYSTAT ( Energy Star ) mainly for residential and commercial lighting class LED Lighting photovoltaic performance requirements, LED temporarily in road lighting column .

FCC is a United States federal law on teletext product of radio disturbance (EMI) Signature limits mandatory certification, LED lamps FCC certification test and the EU CE of electromagnetic compatibility certification testing is quite different, mainly as follows:

1 , LED lamps FCC certification test only EMI (radio disturbance), does not bear EMS (radio interference) test items; CE of electromagnetic compatibility tests are two certification tests are required; < / span>

2 , LED lamps FCC certification is divided into ClassA (industrial, commercial environments using LED lamps) and ClassB (residents environment using the LED lamps) categories, two completely different test limits, CE certification standard radio disturbance only one test limits, limits the size of FCC the ClassB considerable;

3 , LED lamps FCC certification tests conducted disturbances scanning frequencies from 0.15MHz began to 30MHz end, CE certification scan test frequency conducted disturbances from 9KHz began to 30MH end;

4 , LED lamps FCC certified space radiation harassment scan test frequencies from 30MHz began to 1GHz end, CE certification of space radiation harassment scan test frequencies from 30KHz began to 300MH end;

5 , FCC certification requirements more demanding, the EMI standards usually require certification test limits in 6dB more headroom, CE certified EMI test margins In 3dB or above (including the reading point margin) can be ;

UL Certification is a non-compulsory certification in the United States, mainly performance in terms of product safety testing and certification, the certification range does not bear products EMC < span style = "font-family: Arial;"> (electromagnetic compatibility) properties. Following is a brief introduction LED lighting products involved are < span style = "font-family: Verdana;"> UL8750 , UL1310 < / span> and UL60950 . UL8750 apply to be installed at the rated 600V branch or lower non-hazardous locations LED lighting element minimum security requirements apply equally connected to the battery, fuel cell isolation (no valid connection) Power LED light minimum security requirements; UL1310 for containing the input voltage 120 or 240Vac voltage through software or directly into the connection 15 or 20A AC branch circuit or potentially less 150V grounded, use insulated transformers and rectifiers and other components can be incorporated to provide DC or AC energy is expected to be used to provide energy to the low-voltage electricity action CLASS2 power equipment; UL60950 apply information technology ( referred IT) equipment safety standards , including mobile phones, computers and peripheral equipment , such as projectors , printers, etc., but also includes output available with LPS (limited supply) safety circuit power supply;

in LED Lighting Products UL certification, certification test drive power can be used UL1310 or UL60950 . The main difference between the two standards are as follows:

1 , UL1310 is CLASSII (providing limited voltage and capacity of power) power equipment safety standards, through UL1310 certified power of CLASSII power supply, use CLASSII Power do cUL ( Canadian market ) of LED lighting certification, may waive the relevant safety tests; UL60950 is the IT class ( referred IT) equipment safety standards, the applicable scope of certification is greater than < span style = "font-family: Verdana;"> UL1310 , but using through UL60950 certified power to do cUL ( Canadian market certification ) of LED lighting authentication, can not be waived relevant safety tests;

2 , UL1310 standard output voltage at any load condition power supply maximum output voltage ( including no load) exposed contact voltage peak 42.4V , when the device is not can be automatically included in the output circuit disconnect device not more than the maximum output VA 100 VA; UL60950 defines the output voltage under normal conditions, any two an accessible circuit voltage between components, or any of its parts and the circuit can be touched I class equipment protection between the ground terminal voltage does not exceed 42.4V AC peak, or 60V DC value; < / span>

3 , UL1310 certification applies only 120 or 240Vac calibration voltage grid < / span> CLASSII power supplies, UL60950 applicable to the rated input voltage does not exceed 600Vac information technology products for the 277V voltage systems UL certified < span style = "font-family: Verdana;"> LED lighting products drive power, can only refer to UL60950 standard certification testing.

UL certification < / span>

UL certification in the United States are non-mandatory certification, mainly performance testing product safety and certification, the certification range does not bear products EMC (electromagnetic compatibility) Features .
