What is the difference between IEC/ EN 60825-1 and IEC/ EN 62471?

IEC 60825-1: 2007 is a standard issued by the European Union, applicable to safety of laser products emitting laser radiation in the wavelength range 180 nm to 1 mm. Its scope of application would be only applied to LASER products after September 2010, and LED lighting products are no longer covered by the latest version of IEC / EN 60825-1, but need to be assessed in accordance with IEC / EN 62471.

IEC / EN62471 is a test standard for laser products (including LED) issued by the European Union. It is applicable to all lamps and lamp systems, including LEDs, incandescent bulbs, fluorescent lamps, gas discharge lamps, and arc lamps and other lamps and lamps, to evaluate the related light radiation hazards of different lamps and lamp systems. And it fully replaces the IEC / EN60825 standards on the LED product energy level requirements, and increases light biological requirements, including radiation intensity, radiance, etc. Moreover, it classifies product hazard levels according to the test data, Including the exemption level, low-hazard, medium-hazard, high-hazard level. The EU part of the standard EN62471: 2008 has been implemented in 2009.09.01 and EN60825 part of the LED will be completely invalid since 2010.09.01. EU Directive 244/2009 on energy efficiency requirements for non-directional lamps for domestic use also specifies that tests on UV content shall be carried out in accordance with IEC / EN 62471 (including energy saving lamps and incandescent / halogen lamps).

EN62471C light radiation safety testing system mainly measures the spectral power distribution, radiance, irradiance, radiation exposure, radiation exposure, specific effective radiation ultraviolet power, illumination, radiation exposure, radiation exposure, radiation exposure, source size, related color temperature, color, and color products of LEDs, LED module, LED lamp, fluorescent lamp, HID lamp, halogen lamp and other lighting products. Coordinate, color rendering index and color tolerance. The test parameters include ultraviolet radiation weighted irradiance, near ultraviolet radiation, retina blue light risk weighted radiation, retinal heat damage, infrared radiation, visible light and infrared radiation. The lamp can be classified according to the photo biological hazard.

In the past, there is no detailed measurement and evaluation method for the harm to human body caused by optical radiation. The traditional test method is to evaluate the content of ultraviolet or invisible light contained in the light wave. When the LED appears, we evaluate it with the same IEC / EN 60825 standard for laser product. But now, LED products are no longer covered by IEC / EN 60825-1: 2007, but according to IEC / EN 62471 for risk assessment. And IEC / EN 60825 is only suitable for laser products. IEC / EN 62471 is covered by the CE Low Voltage Directive (LVD directive 2006/95 / EC) and is also covered by the Artificial Light Radiation Directive (AORD 2006/25).
