The navigation signal lamp test system is composed of GPM goniophotometer, light intensity calibration system, AC and DC power supply, guide rail system, test clamps and three-dimensional control software. It is used to measure the photometric, colorimetric and electrical parameters of navigation signal lamp composed of various types of light sources. Testable navigation signal lamp sources include incandescent lamp, fluorescent lamp, low-pressure sodium lamp, high-pressure sodium lamp, metal halide lamp, xenon lamp and LED lamp. The measurement parameters include fixed light intensity and horizontal distribution, vertical emission angle light intensity distribution, characteristic surface light intensity curve, circumferential light intensity distribution, vertical light intensity distribution, light range, light color, flash cycle error, beanm angle at 50% peak light intensity, Daylight switch illumination threshold, light intensity, etc.
