Measurement and Analysis Method of Light Intensity Distribution for Street Lamps

Abstract

In order to evaluate the actual illumination effect of high-pressure sodium lamp on the road, a high-pressure sodium lamp illuminance test system is developed in this paper. In the testing of sodium lamp illumination, light intensity distribution is the most important evaluation index. It is also one of the most difficult physical parameters to test due to its large amount of data and high accuracy requirements. This thesis investigates a fast and high-precision testing method for light intensity distribution of high-pressure sodium lamps, so as to improve the measurement of sodium lighting. The system performs light intensity distribution testing in the laboratory, studies the test method of light intensity illuminance distribution of high-pressure sodium lamps, uses Matlab to optically model high-pressure sodium lamps, uses various methods to model the data obtained from the experiments, and analyzes the resulting illuminance data, the system is able to quickly test and evaluate the illuminance of high-pressure sodium lamps after installation.
