Standard Dynamic Glare Light Source Design Method Based on Threshold Increment

Aiming at the problem of inconsistent measurement standards faced by current glare measuring devices, a standard dynamic glare source design method based on threshold increments (TI) is proposed, and a glare measuring instrument calibration system is established. The structure of the standard dynamic glare light source is determined according to the measurement requirements of the threshold increment. In the process of glare measurement, the layout of the glare source is planned and the luminescence of the glare source area is determined under the premise that the position index and solid angle in the laboratory environment and the real street lighting environment are equal respectively. Simulation is performed for the same glare value in different scenes and different glare values in different scenes with a frequency of up to 24Hz to match the glare situation in various environments. The experimental results show that the standard dynamic glare source covers 8.0%~26.7%, and its flicker frequency can be adjusted up to 24 Hz, and the extended uncertainty of simulated glare is 1.3%, which can meet the calibration requirements of various glare measuring instruments.
