Abstract：Photobiological safety and test method of automobile headlamps were researched.On the basis of spectral composition and characteristics of automotive lighting, photobiological hazard of vehicle headlamp light is included the retina heat hazard, near ultraviolet ray hazard and retina blue hazard, in the condition of the wavelength range of 320nm to 1400nm and maximum exposure time of 36s.According to the light intensity distribution characteristics of the vehicle headlamp, test point, measurement field of view and test distance are determined.With 2 groups of 6 HID and LED headlamps, experimental results show that the test results are consistent with the theoretical valuation.This methods and limits value can be used to better judge photobiological safety of the vehicle headlamp.
