The eagle-eyed among you (particularly those who enjoy reading the print copy of the journal rather than perusing the content online) may have noticed some significant changes to the extent of Lighting Research and Technology over recent years. Long-term readers will know that until 2012 only four issues were published each year, which increased to six per year in 2013 and then eight per year from 2015 onwards. But that’s not the only change; there has also been an increase in the number of pages per issue, meaning that overall, the size of journal increased by about 70% in the period since 2014 and by a massive sevenfold since 1999.

你们之中（尤其是那些喜欢阅读期刊的印刷版而不是在线阅读内容的人）眼花may乱，这些人可能已经注意到近年来Lighting Research and Technology的范围发生了一些重大变化。长期读者会知道，直到2012年，每年只出版四期，到2013年，每年出版六期，从2015年开始，每年出版八期。但这不是唯一的变化。每期期刊的页数也有所增加，这意味着总体而言，自2014年以来，期刊的规模增长了约70％，自1999年以来增长了七倍。
