Abstract

This experiment investigated the effects of different machine-mounted area lighting technologies on visual performance in a simulated underground mine environment. The primary objective was to conduct a comparative evaluation of the lighting technologies based on the visual performance of 36 human subjects in a simulated underground mine environment. Incandescent (Incand), fluorescent (Fluor), and light-emitting diode (LED) technologies were used to create four lighting combinations. Visual performance was quantified for the detection of movement in the peripheral field of view and the identification of ground hazards. Measurements were made of the speed (response time measured in milliseconds), the accuracy (the number of targets and objects missed), and the subjective discomfort rating of the glare experienced for each lighting combination. A secondary objective explored the effects of aging on visual performance. The results indicate that lighting combinations which consisted of LED area lights significantly improved visual performance for the detection of hazards found in the peripheral field of view, as well as those found on the ground. They furthermore indicate that age plays a significant role in visual performance.

在中视条件下使用白炽灯、荧光灯和LED机器灯时的视觉性能评估

本实验研究了不同机器安装区域照明技术对模拟地下矿山环境中视觉表现的影响。主要目的是在模拟地下矿井环境中，根据36名受试者的视觉表现，对照明技术进行比较评估。白炽灯(Incand)、荧光灯(Fluor)和发光二极管(LED)技术被用于创建四种照明组合。对视觉性能进行量化，以检测周边视野中的运动和识别地面危险。测量包括速度(以毫秒为单位的响应时间)、准确性(未击中目标和物体的数量)以及每种照明组合对眩光的主观不适程度。第二个目标是探索衰老对视觉表现的影响。结果表明，由LED区域灯组成的照明组合显著提高了检测周边视场中发现的危险的视觉性能，以及在地面上发现的危险。他们进一步指出，年龄在视觉表现中起着重要作用。
