Abstract
The article presents the results of the research on the assessment of photobiological hazards caused by ultraviolet radiation and blue light emitted from low and high-beam headlamps with three different light sources: halogen bulb, xenon-arc and light emitting diodes (LED). The studies show that modern light sources used in automotive industry can be the cause of blue light retinal hazard. Tested headlamps with LED and xenon-arc sources are assigned to RG2 risk group according to to PN-EN 62471:2010, maximum exposure times are in range of 24-40 s and threshold distances 5.3-8.3 m. There are no ultraviolet radiation hazard caused by low and high beam headlamps except for xenon lamp. Obtained results were referred to photometric and colorimetric quantities of tested headlamps.
