最近的一项研究调查了照明对犯罪的影响，该研究考虑了环境光照水平的变化对2010年至2019年美国三个城市记录的犯罪的影响。研究结果显示，天黑后抢劫案的数量显著增加，但并不意味着其他类型犯罪案件的数量有显著变化。目前的研究通过考虑美国三个不同城市记录的犯罪来验证这一点。这项分析证实了天黑后抢劫案在统计学上的显著增加。这些数据并不表明环境光照水平的变化对总体犯罪率有实际相关的影响:换句话说，照明对减少犯罪的潜在好处是有限的。

A recent study investigated the influence of lighting on crime by considering the effect of change in ambient light level on crimes recorded in three US cities for the ten-year period 2010 to 2019. The results suggested a significant increase in robbery after dark, but did not suggest significant change in for any other type of crime. The current study was conducted to validate this by considering crimes recorded in three different US cities. This analysis confirmed the statistically significant increase in robbery after dark. These data do not suggest that change in ambient light level has a practically relevant effect on overall crime counts: in other words, the potential benefit of lighting for crime reduction is limited.
