摘要
为了研究装甲车辆内局部环境照明的视觉工效问题,受试者接受三种强度曝光,而后在低照度水平下判别视标方向,记录正确判别反应时。结果表明:在三种曝光强度下,随着视标照度水平的提高,受试者判别反应时曲线都呈先急后缓的下降趋势,并在视标照度为50 lx时出现一有效拐点。据此,建议在无特殊视觉要求的情况下,装甲车辆局部环境照度应不低于50 lx,或适当扩展装甲车辆观察窗口的大小和数量。
To explore an ergonomic lighting level in local environment of armored ear,subjects are requested to judge the direction of targets under low lighting, after accepting three kinds of compelling exposal, and the reaction time is recorded. Results indicate： after compelling exposal,with the increase of low lighting level,the three reaction time curves have a same decline tendency,and there is an effective inflexion at 50 lx lighting level. It is suggested that 50 lx is an ergonomic lighting level in local environment of armored car if it has not special visual request, or adding the size and amount of the armored car＇ s observing window properly.
