Mandatory standard to meet for all LED Products to be sold in Europe, China, Canada and Asia
IEC 62471: 2009 “Photobiological Safety of Lamps and Lamp Systems”
The motive of this standard is to protect the user from injuries and blindness caused due to UV, IR and EM radiation emitted by LED Lights. If your product is not comply with IEC 62471 then your product is prohibited to sale in the above countries. Even for any damage you may be liable. Unfortunately, many manufacturer are unaware of photobiological safety testing. So, to export your products in the market ontact ITC India Pvt Ltd for Photo biological testing and you will be provided with best assistance. Please write to us at firstname.lastname@example.org or visit us at www.itcindia.org .
Particularlly this standards states the exposure limits, reference measurement technique and classification scheme for the evaluation and control of photobiological hazards from all electrically powered incoherent broadband sources of optical radiation, including LEDs but excluding lasers, in the wavelength range from 200 nm through 3000 nm.
Here is a list of the tests to be performed in IEC 62471
|Angular sub tense of source and measurement field-of-view
|Actinic UV hazard exposure limit for the skin and eye
|Near-UV hazard exposure limit for the eye
|Retina blue light hazard exposure limit
|Retina blue light hazard exposure limit – small source
|Retina thermal hazard exposure limit
|Retina thermal hazard exposure limit – weak visual stimulus
|Infrared radiation hazard exposure limit for the eye
|Thermal hazard exposure limit for the skin
|Continuous Wave lamps – Lamp classification
The output of the lights must not exceed the levels of all the radiations mentioned in IEC 62471.
Emission limits for the above testis as follows :
|Low risk Limits
|Mod risk Limits
|Blue light Small source
|Retinal thermal, weak visual stimulus**
|IR radiation eye
