LED Radiation Safety Test

IEC62471-2006(CIE S009) Photobiological Safety of Lamps and Lamp System and IEC TR62471-2(2009) Guidance on Manufacturing Requirements Relating to Non-laser Optical Radiation Safety have be published addressing hazard to human (mostly eye and skin), and are completely suitable to assess the optical radiation safety of non-laser sources, such as LED products, UV radiation in general lighting products and etc. 

It also according to IEC/EN62471/CIES009, IEC/TR 62778, GB/T 20145, IEC/EN 60598 Annex P, IEC/EN 60432, IEC/EN 60335, GB 7000.1 and 2009/125/EC.

The hazard exposure level of optical radiation of tested sources which may be related from 200nm to 3000nm shall be determined based on the measurement of spectral irradiance and spectral radiance in specified measuring geometry relating with exposure duration.

The IEC 62471 measurement equipment is specialized for determination of the optical radiation hazard exposures specified in IEC 62471, including as follows:
Actinic UV hazard exposure (weighted irradiance from 200nm to 400nm) for the skin and eye, 

• Near-UV hazard exposure (irradiance from 315nm to 400nm) for the eye, 
• Retinal blue light hazard exposure (weighted radiance from 300nm to 700nm),
• Retinal Blue light hazard exposure(weighted irradiance, 300-700nm) - small source,
•Retinal thermal hazard exposure (weighted radiance from 380nm to 1400nm),
• Retinal thermal hazard exposure (weighted radiance; 780-1400nm) - weak visual stimulus, 
• Infrared radiation hazard exposure (irradiance from 780nm to 3000nm) for the eye,
