Measurement and Analysis of the Blue Light Hazard Efficacy of Luminous Radiation of Indoor LED Lamps

Measurement and analysis of the blue light hazard efficacy of luminous radiation of different indoor LED lamps are done in this paper. Measurements of spectral power distribution, photometric, colourimetric parameters and efficacy of 21 tested indoor LED lamps with a CCD spectroradiometer in an integrating sphere in tabular form are presented. Comparison of the spectral dependences of blue light hazard weighting function, measured spectral power distribution and Blue Weighted Watts of the indoor LED lamps studied, having different correlated colour temperature is done. Graphical and defined linear analytical dependence of blue light hazard efficacy of luminous radiation on the correlated colour temperature of the measured indoor LED lamps are done. Conclusions regarding the measured and calculated blue light hazard level control indicators of the tested indoor LED lamps are made.
