62471:2006 EN & 62471:2008 IEC will be officially implemented in September 1, 2009, with immediate effect all the LED lamps will be added to the standard, the transition period is one year, the original IEC/EN60825-1 report can also be used, but until September 1, 2010 will be completely ineffective, there are some foreign customers require domestic suppliers to provide EN62471 testing report, in addition to the new standard, customs will strengthen the query, the relevant business in advance to prevent, according to the new standard IEC/EN62471 detection, to avoid unnecessary trouble.
A: standard background
IEC/EN 62471 is designed to evaluate the optical radiation hazards associated with different lamps and lamp systems, and to replace the IEC/EN60825 standards in the requirements of the LED product energy level, increase the requirements of the optical biology, including radiation intensity, radiant brightness, and according to the test data on the product hazard classification, including the exemption level, low damage, medium hazard, high hazard level. The EU part of the standard EN62471:2008 has been implemented in 2009.09.01, EN60825 on the part of the LED will be completely ineffective in 2010.09.01.
IEC/EN60825 is mainly for the single wavelength of the light energy testing
IEC/EN62471 is mainly used to measure the wide band of light, and the time, angle, sensitivity, etc.
Two: all the products except laser light and lamp system. (a single wavelength laser is easy to test, the influence of ordinary lamps as light emitting body and diffuser, lens, optical components such as device and may is a wide band light source)
Three: testing the wavelength range
Optical radiation in the range of 3000Nm to 200nm
Four: test parameters and object test parameters:
1 irradiance (radiation flux divided by the area of the unit, the unit: W? M-2)
2 radiance (irradiance divided by the field, through the irradiance conversion) test object
1 the skin and eyes of the ultraviolet harm
Near UV hazard (315nm-400nm) of 2 eyes
3 retina blue light hazard
4 retina blue light hazard (light source)
5 retinal thermal hazard
6 retinal thermal hazard (for weak visual stimuli) (780nm-1400nm)
7 eyes of infrared radiation hazard (780nm-3000nm)
8 skin heat hazard (380nm-3000nm)
Five: the results of the judgment
1 continuous light: no danger; the 1 category of danger (low risk); the 2 category of danger (Zhong Wei); the 3 category of dangerous (high risk) 2 pulse light: 3 in accordance with the 1 categories of dangerous; 2 no more than a single pulse of radiation limits according to no danger; 3
