By: NVision, Inc. Lighting Science designs, develops, manufactures and markets LED lighting solutions that are environmentally friendly and more energy efficient than traditional lighting products. The company uses the HandHeld scanner to evaluate many of its LED solid state lighting components. The company’s new RoadMaster™ street light is one example of the component parts evaluated with the scanner. The RoadMaster provides a reduction in energy costs during its extended operating life, helping municipalities and communities avoid soaring energy and maintenance costs associated with traditional high pressure sodium (HPS) street lights. The RoadMaster pays for itself by avoiding just one HPS lamp replacement, let alone the 4-6 traditional street light changes it is expected to avoid over its rated life. The Roadmaster fixtures are built around large 2 feet long by 1 foot wide aluminum die castings. The aluminum has a tendency to scavenge the steel dies so over time the features of the castings gradually move out of tolerance. The steel dies used to make the castings typically last from 25,000 to 50,000 shots. It’s critical to inspect a sample of parts received from suppliers to ensure that they are within specifications. But the geometry of the parts is so complex that it would take several days to inspect them with gauges and blocks. As for using a CMM, it would take an estimated week to write a program to inspect each of the many variants of these parts and about 4 hours to inspect each part because of the large number of points that need to be touched one at a time to validate the 3D geometry. “We heard about the NVision HandHeld scanners’ ability to quickly capture the complete geometry of a complex part and thought it would be perfect for this application,” The HandHeld scanner is a revolutionary portable scanning device which is capable of capturing 3D geometry. The scanner is attached to a mechanical arm that moves about the object, freeing the user to capture data rapidly and with a high degree of resolution. An optional tripod provides complete portability in the field. Intuitive software allows full model editing, polygon reduction, and data output to all standard 3D packages. NVision software allows you to compare the scan data of your parts against your CAD model.
