My tenure as Chair of the LR&T Editorial Board has coincided with several changes. The number and size of the issues within each LR&T volume has increased and more importantly the quality of the content, as assessed by the Impact Factor, has also increased to well above the critical value of 2. This is due to the authors of papers, but also the work of the LR&T Board, the previous Editor in Chief, Peter Boyce, the new Editor in Chief, Steve Fotios and the previous Chair of the Editorial Board, David Carter. With the growing contribution of seven new Associate Editors, there is now a real opportunity to move the Journal forward under the new Chair, Teresa Goodman, who begins her tenure in November 2020. In addition to publishing research output, there is also a vital need to facilitate interaction with the leading researchers across the light and lighting landscape. The LR&T Symposia are designed to do this and these bi-annual events are now an established part of the LR&T, SLL and international research event calendar. The output of these symposia, together with specially commissioned issues, will only add to the relevance and impact of LR&T. It is suggested that sustainability is at the top of most national research agendas, and there are plenty of sustainability topics around light and lighting left to explore. The Bruntland Report of 1987 is commonly cited as the first initiative to establish sustainable development through the three main pillars of economic growth, environmental protection and social equality. Internationally, economic growth is generally given priority over the other two pillars. An important part of the social equality pillar is the provision of inclusive environments. In particular for those engaged in light and lighting research, there is a need to address the requirements of people who have a visual impairment or are blind. Whilst several helpful and research evidence-based lighting guidance documents are available, there are many underlying research questions that need to be addressed. One is the impact of the wide range of eye pathologies on the perception of colour and contrast. In particular, there is very little work on the validity of the spectral response; from the standard blue, green and red light sources; of the three retinal cone types that are sensitive to short, medium and long wavelength light. In simplistic terms, only the retinal cone response of those with good vision form the basis of the widely accepted models for the perception of colour and contrast. However, it seems reasonable to assume that those with eye pathologies, e.g. macular degeneration, do not have the same cone spectral responses as those who have good vision. These cone response differences need to be examined so that an accurate assessment of colour and contrast perception can be determined. This can then be used to provide the sustainable and inclusive environments that we all need.

社论：为包容性的 LR&T 环境着色

我担任 LR&T 编辑委员会主席期间发生了几次变化。每个 LR&T 卷中问题的数量和大小都增加了，更重要的是，影响因子评估的内容质量也增加到远高于临界值 2。这是由于论文的作者，还有 LR&T 董事会、前任主编 Peter Boyce、新主编 Steve Fotios 和前任编委会主席 David Carter 的工作。随着 7 位新副主编的贡献不断增加，现在有真正的机会在新主席 Teresa Goodman 的领导下推动期刊向前发展，Teresa Goodman 将于 2020 年 11 月开始任职。除了发表研究成果外，还迫切需要促进与灯光和照明领域领先研究人员的互动。LR&T 研讨会旨在做到这一点，这些两年一度的活动现在已成为 LR&T、SLL 和国际研究活动日历的一部分。这些专题讨论会的成果，连同特别委托的问题，只会增加 LR&T 的相关性和影响。有人建议可持续性是大多数国家研究议程的首要任务，并且还有许多围绕光和照明的可持续性主题有待探索。1987 年的布伦特兰报告通常被认为是通过经济增长、环境保护和社会平等三大支柱建立可持续发展的第一个倡议。在国际上，经济增长通常优先于其他两个支柱。社会平等支柱的一个重要部分是提供包容性环境。特别是对于从事灯光和照明研究的人来说，需要解决视力障碍或盲人的需求。虽然有一些有用的研究循证照明指导文件可用，但仍有许多潜在的研究问题需要解决。一是广泛的眼病对颜色和对比度感知的影响。特别是，关于光谱响应有效性的工作很少；来自标准的蓝色、绿色和红色光源；对短、中、长波长光敏感的三种视网膜锥体类型。简单来说，只有那些具有良好视力的人的视网膜锥体反应构成了广泛接受的颜色和对比度感知模型的基础。然而，假设患有眼病（例如黄斑变性）的人没有与视力良好的人相同的锥光谱响应，这似乎是合理的。需要检查这些视锥响应差异，以便可以确定对颜色和对比度感知的准确评估。然后，这可用于提供我们所有人都需要的可持续和包容性环境。需要检查这些视锥响应差异，以便可以确定对颜色和对比度感知的准确评估。然后，这可用于提供我们所有人都需要的可持续和包容性环境。需要检查这些视锥响应差异，以便可以确定对颜色和对比度感知的准确评估。然后，这可用于提供我们所有人都需要的可持续和包容性环境。
