Radiant Vision Systems PM-HL™ Headlamp Evaluation Module PM-HL™

Evaluation tool kit specific to US and ECE headlamp standards Today's headlights include smart illumination, adaptive systems like matrix LED- or laser-based systems, and other technology that dynamically illuminates roadways while meeting the requirements of national safety regulations. Because they distribute light over a large spatial area, with specific and sometimes changing geometries, headlamps must be tested against several visual criteria to ensure proper illumination at all settings. An efficient method for evaluating headlamp performance is to project the light source onto a wall or screen and use a connected imaging colorimeter to capture the entire illumination distribution in a matter of seconds. The complete lighting assembly can then be analyzed in a single image using a number of user-defined criteria in Radiant's PM-HL™ software module, designed specifically for headlamp evaluation. A typical PM-HL system consists of: ProMetric I Imaging Colorimeter or ProMetric Y Imaging Photometer PM-AC4001 Metal Halide illumination Calibration Lamp PM-HL Software Key Features: Point of Interest set that contains both US and ECE POIs Conversion between illuminance distribution, luminous intensity distribution and roadway illumination distribution Representation of a road overlaid on the measurement bitmap Automatic determination of the "beam elbow" datum position and alignment of camera image to that position Evaluation of ECE Reg 20 test points for left or right hand drive Headlamp cut-off gradient calculation per regulation Multiple data analysis functions, including bitmaps, isoplots, cross-sections, gradient lines and more Simplified pass / fail testing Head Lamp Analysis Report to document results of evaluations
