PM-HL™ Headlamp Evaluation Module for ProMetric­® Software

ProMetric® Software provides equipment control, data acquisition and image analysis when used with ProMetric Imaging Photometers and Colorimeters. Together, this combination provides rapid and accurate measurement of luminance and color for a broad range of light sources, displays, backlit components, and optical materials.

PM-HL is a headlamp evaluation module for ProMetric Software that enables accurate evaluation of headlamp beam patterns. It also permits conversion of headlamp beam patterns into roadway illumination distributions. A typical PM-HL system consists of:

• ProMetric Imaging Colorimeter or Photometer
• PM-AC4001 Metal Halide Illumination Calibration Lamp
• PM-HL software

Benefits:

• Quickly and economically qualify the illuminance, chromaticity and color temperature of lighting products versus lighting regulations or alternative lamps
• Enjoy lower capital investment and reduced measurement expense than with goniometric methods
• Eliminate the need for a 25 meter dark room
• Provide finely-resolved, quantitative and graphical analysis

Typical Applications:

PM-HL enables accurate evaluation of headlamp beam patterns and converts headlamp beam patterns into roadway illumination distributions.

• Light source illuminance distribution measurement
• Evaluation of ECE and US regulated test points
• Evaluation of custom test points
• Evaluation of beam pattern cut-off gradients
• Conversion to luminous intensity distribution
• Conversion to roadway illumination distribution
