Abstract: 

The conditions for the formation of an excess dose of blue light produced by the LED lighting were examined. It is shown that light-biological safety assessment carried out in accordance with GOST R IEC 62471-2013 need to be clarified, taking into account changes in the pupil of eye’s diameters when LED lighting and spatial distribution of the light-absorbing blue light (460 nm) of the pigment in the macula influences it. Methodical principles of calculation of an excess dose of blue light in the spectrum of LED lighting comparing to sunlight are presented. It is indicated that today in the USA and Japan the concept of LED lighting has changed and LED white light been developed to minimize disturbances of health risks. This concept applies not only to general lighting in the United States, but also to monitors and car headlights.

Keywords: 
LED, excess dose of blue in the spectrum of artificial white light sources, photo-biological security, national security
