Goniophotometer for Traffic Signal Lamps

LSG-1950S is a high accuracy automatic test system for luminous intensity distribution of traffic signal luminaires and it can be applied to quality evaluation and quality control. It fully meets the Final Report PC13050202 Oregon, ECE-R65, FMVSS108, GB13954 and GB 25991 Standard.

Standard:
ECE-R65 “Special Warning Lights”
FMVSS108 “Lamps, re-flective devices, and associated equipment. “
IEC60662(GB13954 ) “High-pressure sodium vapour lamps”
GB 25991 “Automotive headlamps with LED light sources and/or LED modules”

Specification:
• Rotations of samples under test around both vertical axis (-90°~+90°) and horizontal axis (-35°~+35°)
• Accuracy of angle: 0.1°
• Resolution of angle: 0.01°
• Photometer detector: CIE class A (standard class) accuracy
• Software controls everything with high intellectual faculties and simple operation

By selecting different test scheme and jig, you can replace different samples under test rapidly.
