Paper Abstract

The paper presents a new auto-testing system for detection of photometry quantity and chromatic characteristics of vehicular lamp. The system, according to the national standard, can automatically and accurately inspect illumination, chromaticity, luminous flux and luminous intensity. The system consists of one mechanical turning table and two instruments, controlling by computer. The turning table has high precision with 0.01 degree(s) resolution. The illumination meter can be automatic range-change, completely adaptable for automatic acquisition by computer. Using precious grating spectrometer, CCD signal processing and optic fiber probe, the colorimeter can accurately inspect the tri-stimulus value, chromaticity coordinate and spectral radiant intensity. The testing repeatability is under 0.35%. The system realizes digital display and controls by computer. The system has been used in vehicular lamp factory and testified satisfactory performance.
