Lighting has more functions than simply illuminating spaces. For humans, light is the main signal that aligns our body’s internal clock, regulating circadian rhythms. This process instructs our bodies to wake up in the morning, become alert during the day, and feel sleepy at night. Disruption of these rhythms can impact neurological and psychiatric health, including cognitive performance. We can utilize light for mood improvements and better cognitive performance to create a suitable learning environment for students in educational buildings. These non-visual effects of light need to be considered from the beginning of the design process, making an interdisciplinary effort necessary. Even with adequate light and dark, the human eye reacts differently under various conditions, influenced by light’s photometric and colorimetric properties. While natural sunlight is ideal for aligning with our biological clock, it is not always sufficient, making artificial lighting essential indoors. LED technology offers promising solutions, catering to our non-visual needs in the absence of natural light and providing energy efficiency. This study reviews the literature that includes students’ cognitive performance and well-being, energy efficiency, running costs, and environment-related issues such as light pollution. It aims to explore the impact of lighting design in learning environments.

优化教育环境中的照明设计以增强认知能力：文献综述


照明的功能不仅仅是照亮空间。对于人类来说，光是调整我们身体内部时钟、调节昼夜节律的主要信号。这个过程指示我们的身体早上醒来，白天变得警觉，晚上感到困倦。这些节律的破坏会影响神经和精神健康，包括认知能力。我们可以利用光来改善情绪和提高认知能力，为教育建筑中的学生创造合适的学习环境。这些光的非视觉效果需要在设计过程的一开始就考虑，因此需要跨学科的努力。即使有足够的光线和黑暗，人眼在各种条件下也会受到光的光度和色度特性的影响而做出不同的反应。虽然自然阳光非常适合与我们的生物钟保持一致，但它并不总是足够的，因此室内的人工照明是必不可少的。LED 技术提供了有前途的解决方案，满足了我们在没有自然光的情况下的非视觉需求，并提供了能源效率。本研究回顾了包括学生的认知表现和幸福感、能源效率、运营成本以及与环境相关的问题（如光污染）的文献。它旨在探索照明设计对学习环境的影响。
