NIOSH Jupiter II Wide Area Light
The NIOSH Mining Program conducts mine illumination research to address the visual needs of the aging miner workforce and to improve miner safety by reducing glare and improving a miner’s ability to see mine hazards associated with slip, trip, and fall events and moving machinery accidents. This research enables improvements in mine lighting so miners can better see hazards, thereby reducing the potential for accidents. One result of this research is a light-emitting diode (LED) area light called the NIOSH Jupiter II Wide Area Light.
NIOSH developed the Jupiter II Wide Area Light wide area light for roof bolters and the illumination of working areas. The design objectives were to maximize area illumination while reducing glare. Manufacturers and mine operators can mount the Jupiter II in a variety of positions on equipment and in general work areas. The top photo shows the illumination from a typical LED machine headlight used on mining machines, and the bottom photo shows the increase in illumination from the Jupiter II.
