LED manufacturers and export products with which manufacturers of LED and electronic products (DVD, LED toys, LED shower, etc.) should pay attention to it! 

 IEC 62471:2006 & EN 62471:2008 was September 1, 2009 began formal implementation, effective immediately, all the LED lights will be added to the standard of measurement, the transition period of one year, the original report can also be used IEC/EN60825-1 However, to September 1, 2010 onwards will be completely ineffective, there are some requirements of domestic suppliers, foreign customers must provide the EN62471 test report, also out for the new standards will strengthen the power of the customs of the query, the relevant enterprises in advance please preventive measures, according to new standards IEC/EN62471 testing, shipment to avoid unnecessary trouble. 

 A: The standard background 

 IEC / EN 62471 for the purpose of assessment and different lamps and lamp systems related to the optical radiation hazards, and completely replace the IEC/EN60825 standard LED products on the requirements of energy levels, increasing the light of biological requirements, including the radiation intensity, radiation brightness, etc., and test data based on the hazard classification of products, including the exemption level, low hazard, medium hazard, high hazard level. The EU part of the standard EN62471: 2008 has started 2009.09.01, EN60825 part on the LED will be 2010.09.01 completely ineffective. 

 IEC/EN60825 mainly on a single wavelength of light to calculate the energy test 

 IEC/EN62471 mainly on broad-band measurements of light, and comprehensive eye and skin reaction time to light, angle, and other aspects of sensitivity calculations 

 II: application of laser products in addition to all the other lamps and lamp systems. (Single-wavelength laser easy to test, ordinary light and diffuse the light body, lens, auxiliary devices such as the impact of optical components may be a broadband light source) 

 III: Testing the wavelength range 

 200nm to 3000nm wavelength range of optical radiation 

 IV: The test parameters and test the parameters of the object: 

 1. Irradiance (radiant flux divided by unit area, unit: W? M-2) 

 2. Radiance (irradiance divided by the field, you can convert irradiance) test object 

 1. UV damage skin and eyes 

 2. The eyes of the near ultraviolet damage (315nm-400nm) 

 3. Retina against blue light 

 4. Retina against blue light (small light source) 

 5. Retinal thermal hazard 

 6. Retinal thermal hazards (for weak visual stimuli) (780nm-1400nm) 

 7. The eyes of the infrared radiation hazards (780nm-3000nm) 

 8. Cutaneous heat damage (380nm-3000nm) 

 V: Results of the judging 

 1. Continuous light: no risk; a class of risk (low risk); dangerous Category 2 (medium risk); 3 types of dangerous (high risk) 

 2. Pulse Light: 1. More than 3 categories according to radiation risk limits; 2. No more than a single pulse light emission limits under the no-risk; 3. Did not exceed the radiation limits of the multi-pulse modulation in accordance with the classification of continuous light 

 Part of the market appears cheap EN62471, EN60825 standards still use the report template: update directly to the standard EN62471, the actual content of the standard did not update related businesses cautious.
