Proper lighting plays a critical role in enabling miners to detect hazards when operating a roof bolter, one of the most dangerous mining machines to operate; however, there has not been any lighting research to address the walk-thru type of roof bolter commonly used today. To address this, the Saturn light was designed to directly address walk-thru roof bolter safety by improving trip hazard illumination. The visual performances of 30 participants that comprised three age groups were quantified by measuring each participant's visual performance in detecting trip objects positioned on the two floor locations within the machine's interior working space. The lighting conditions were the existing compact fluorescent lights (CFLs) and the Saturn LED area light developed by NIOSH researchers. Three intensities of the Saturn lights were used, 100%, 75%, and 50%, all of which resulted in better visual performance, and up to a 48% reduction in average trip detection time compared to the CFL. For the Saturn trip object miss rates were <0.5% for all age groups in contrast to the CFL, which ranged between 32.5% for the youngest group and 50.4% for the oldest group.

用于改进步行式屋顶锚杆机的绊倒物体检测的 LED 照明

适当的照明对于矿工在操作锚杆机（最危险的矿机之一）时能够检测到危险起着至关重要的作用；然而，目前还没有任何照明研究来解决当今普遍使用的步行式锚杆机。为了解决这个问题，土星灯旨在通过改善绊倒危险照明来直接解决步行屋顶锚杆的安全问题。通过测量每个参与者在检测位于机器内部工作空间内两层位置上的绊倒物体时的视觉表现，对包含三个年龄组的 30 名参与者的视觉表现进行量化。照明条件是现有的紧凑型荧光灯 (CFL) 和 NIOSH 研究人员开发的土星 LED 区域灯。使用了三种强度的土星光，100%、75% 和 50%，所有这些都带来了更好的视觉性能，与 CFL 相比，平均行程检测时间减少了 48%。与 CFL 相比，土星旅行的对象遗漏率在所有年龄组中均 <0.5%，在最年轻组的 32.5% 和最年长组的 50.4% 之间。
