Within the visible light spectrum, blue light (400– 500 nm) is of particular importance. If the result is below 100 W.m-2.sr-1, then the assessment result is … One should therefore consider the diameter of the circular area evaluated by each IEC 62471 risk group - RG0 (20 … Therefore, it is important to identify the blue-light hazard under various welding conditions. The IEC 62471:2006 norm explains about how to measure Blue Light Hazard, tha could lead to photoretenitis. In addition to Z80.3-2015, we also consider ANSI Z87.1-2015, which identifies the wavelengths of blue light hazard and identifies a peak Hazard Factor at 435nm to 440nm. Nanometer (nm): A nanometer is the extremely small unit used to measure lengths of light waves. Artificial Lighting and the Blue Light Hazard. Nanometer (nm): A nanometer is the extremely small unit used to measure lengths of light waves. In consideration of the blue light hazard, classifications can be transferred only if a measurement of true radiance of the primary light source was made.
Measurement of Optical Radiation to Assess the Blue Light Hazard Karl Schulmeister, Martina Schwaiger∗, Georg Vees, Christian Schmitzer Austrian Research Centers Seibersdorf, A-2444 Seibersdorf Austria One should therefore consider the diameter of the circular area evaluated by each IEC 62471 risk group - RG0 (20-mm), RG1 (11-mm), and RG2 (0.34-mm diameter). Instrument Systems is represented in all major international standard bodies. 1 shows GL SPECTIS 5.0 UV VIS spectroradiometer with an operating range of 200 to 800 nm. The objective was to quantify the blue-light hazard from gas metal arc welding (GMAW) of aluminum alloys. The retinal blue light hazard is determined by measuring the spectral radiance of the source over the range 300–700 nm (applying the blue light hazard weighting function) and over the appropriate FOV for the risk group considered. The purpose of the blue light hazard measuring station from Instrument Systems is, e.g. Optical Radiation Measurement Optical radiation sources include artificial light sources and natural light radiation sources. Artificial Lighting and the Blue Light Hazard. With the ledlamps becoming more and more powerful and given that the blue content of the light from leds in increasing as well, there is a growing concern for blue light hazard.
to evaluate and classify LED lamps and luminaires according to blue light hazard as described in Standards IEC 62471 and IEC/TR 62778.. IEC 60598-1 adopted IEC/TR 62778 “Application of IEC 62471 for the assessment of blue light hazard to light sources and luminaires “.
