In 2018 we published the 50th volume of Lighting Research and Technology. To mark this achievement, issue 50(1) comprised a series of invited articles which focused on several key themes of lighting research, authored by leading researchers in those themes. In the past decade LR&T has increased in extent – both physically (an increase from four to eight issues per year) and geographically (a greater proportion of articles are now from international authors). The current impact factor is 2.331, an improvement on that for previous years and the first time it has exceeded 2.0. One important factor behind the success of LR&T has been the work of Peter Boyce as Editor-inChief, a role he undertook since issue 40(1) in 2008. Peter decided to stand down as Editor at the end of 2019; to mark his achievements as Editor and as a researcher, issue 50(8) included a series of discussions from several authors describing their favourites from amongst Peter’s many articles. Looking ahead there are short-term and long-term plans for the editorial team. The long-term plan is that, from January 2021, I will be taking over the role of Editor-in-Chief in collaboration with seven Associate Editors. In other words, we require eight of us to carry out the work Peter conducted alone for many years. The contribution of the Society for Light and Lighting in supporting and enabling these changes is greatly appreciated. The short-term plan, for 2020, is that Associate Editors will be taking more responsibility for managing the review process with administration support from Sage: this will ensure continuation of the rigorous review process which Peter and others have carefully established. The seven Associate Editors are Myriam Aries, Teresa Goodman, Kevin Mansfield, John Mardaljevic, Ashish Pandharipande, Michael Royer and Peter Thorns. They were chosen, primarily, for their knowledge within a specific area of research, but they also represent a broader geographic area. There are changes also within the editorial board. Luke Price is coordinating the editorials and opinion articles. Geoff Cook will be standing down as chairman of the board in 2021, and alongside considering his replacement we are considering the gender balance of the board.

社论

2018 年，我们出版了《照明研究与技术》第 50 卷。为了纪念这一成就，第 50(1) 期包含一系列受邀文章，重点关注照明研究的几个关键主题，由这些主题的主要研究人员撰写。在过去十年中，LR&T 的范围有所增加——无论是在物理上（从每年四期增加到八期），还是在地理上（现在有更大比例的文章来自国际作者）。目前影响因子为2.331，较往年有所提升，首次超过2.0。LR&T 成功背后的一个重要因素是 Peter Boyce 作为主编的工作，这是他自 2008 年第 40(1) 期以来担任的角色。Peter 决定在 2019 年底辞去主编的职务；纪念他作为编辑和研究员的成就，问题 50(8) 包括几位作者的一系列讨论，描述了他们在 Peter 的许多文章中最喜欢的。展望未来，编辑团队有短期和长期计划。长期计划是，从 2021 年 1 月起，我将与七位副主编合作，接任主编的角色。换句话说，我们需要我们八个人来完成彼得多年来独自进行的工作。非常感谢光与照明协会在支持和实现这些变化方面的贡献。2020 年的短期计划是，在 Sage 的行政支持下，副主编将承担更多管理审核流程的责任：这将确保继续进行 Peter 和其他人精心建立的严格审核流程。七位副主编是 Myriam Aries、Teresa Goodman、Kevin Mansfield、John Mardaljevic、Ashish Pandharipande、Michael Royer 和 Peter Thorns。之所以选择他们，主要是因为他们在特定研究领域的知识，但他们也代表了更广泛的地理区域。编辑委员会内部也发生了变化。Luke Price 正在协调社论和意见文章。Geoff Cook 将于 2021 年卸任董事会主席，在考虑接替他的同时，我们正在考虑董事会的性别平衡。编辑委员会内部也发生了变化。Luke Price 正在协调社论和意见文章。Geoff Cook 将于 2021 年卸任董事会主席，在考虑接替他的同时，我们正在考虑董事会的性别平衡。编辑委员会内部也发生了变化。Luke Price 正在协调社论和意见文章。Geoff Cook 将于 2021 年卸任董事会主席，在考虑接替他的同时，我们正在考虑董事会的性别平衡。
