Goniophotometer for Airfield Lighting

LSG-1940 Goniophotometer for Airfield Lighting is a Type-A (CIE A-α) goniophotometer that rotates the luminaire under test. By driving the aviation ground light to rotate along both horizontal and vertical axes, the system captures illuminance data at various spatial angles and calculates the full-space luminous intensity distribution. It enables the measurement of key photometric parameters, such as the average luminous intensity of the main beam, peak luminous intensity, and minimum luminous intensity within specific restricted zones.

LSG-1940 integrates a digital electrical parameter measurement module to simultaneously acquire electrical performance data—including voltage, current, power, and power factor—from the luminaire under test. Dedicated testing software automates data processing and generates photometric and electrical performance test reports in both Chinese and English. The equipment complies with testing standards for aviation ground lighting set by civil aviation authorities and organizations such as ICAO, EASA, and FAA; it is suitable for the R&D, type testing, and factory inspection of various steady-burning aviation ground lights, including runway lights, taxiway lights, and warning lights.
