Adequate sleep is crucial for students to maintain the best possible performance in the classroom. However, a natural biological tendency among teenagers to stay up later in the evening combined with early morning start times at most schools can result in a lack of sleep among middle and high school students that can impact their classroom performance. Research has shown that various properties of indoor lighting can influence the human cycle of sleep and wakefulness, known as circadian rhythm. This Partnerships for Innovation: Building Innovation Capacity (PFI:BIC) project from Brown University aims to better understand those light properties and design a dynamic, intelligent lighting system that can effectively shift the circadian phase of students to help them remain alert and focused during the school day.The project aspires to advance smart lighting by developing a wireless networked biophilic lighting system that will deliver lighting tunable in terms of spectral band(s), intensity, directionality, duration, and season. An essential first step will be to determine the efficacy of this system in suppressing the production of melatonin, a hormone that mediates the circadian cycle. Working with Digital Lumens, the team members will design and integrate several of these wirelessly networked LED systems that are equipped with sensors and actuators. They will then test them in the Sleep Labs of Brown University/Bradley Hospital, via the monitoring and control of the lighting conditions, and analyze the physiological responses in real time. The "prescriptions", in the form of control algorithms and wireless networked control and sensor modules, will be the basis for field-tests in a local school, conducted in cooperation with school administrators, teachers, parents, and students.The project will be undertaken by an interdisciplinary collaboration between the laboratories of Professor Jimmy Xu, from Brown University's School of Engineering, and Professor Mary Carskadon, from the Department of Psychiatry and Human Behavior at Brown University's Warren Alpert Medical School. The industrial partner is Digital Lumens (Boston, MA), a small business pioneer in the development and implementation of next-generation LED lighting solutions.

充足的睡眠对于学生在课堂上保持最佳表现至关重要。然而，青少年晚睡的自然生物倾向加上大多数学校早上上课的时间，可能会导致中学生和高中生睡眠不足，从而影响他们的课堂表现。研究表明，室内照明的各种特性会影响人类的睡眠和觉醒周期，即昼夜节律。 布朗大学的创新伙伴关系：建设创新能力 (PFI:BIC) 项目旨在更好地了解这些光特性，并设计一个动态的智能照明系统，该系统可以有效地改变学生的昼夜节律阶段，帮助他们在学习期间保持警觉和专注。该项目旨在通过开发无线网络亲自然照明系统来推进智能照明，该系统将提供在光谱带、强度、方向性、持续时间和季节方面可调的照明。 重要的第一步是确定该系统在抑制褪黑激素（一种介导昼夜节律周期的激素）产生方面的功效。 团队成员将与 Digital Lumens 合作，设计并集成多个配备传感器和执行器的无线联网 LED 系统。 然后，他们将在布朗大学/布拉德利医院的睡眠实验室中通过监测和控制照明条件对它们进行测试，并实时分析生理反应。 这些“处方”以控制算法、无线网络控制和传感器模块的形式出现，将作为在当地学校进行现场测试的基础，与学校管理人员、教师、家长和学生合作进行。该项目将该研究由布朗大学工程学院的 Jimmy Xu 教授和布朗大学沃伦阿尔珀特医学院精神病学和人类行为系的 Mary Carskadon 教授的实验室之间的跨学科合作进行。工业合作伙伴是 Digital Lumens（马萨诸塞州波士顿），该公司是开发和实施下一代 LED 照明解决方案的小型企业先驱。
