Abstract

The use of LEDs for plant lighting (phytolighting) provides a more energy- efficient alternative to traditional lighting methods. Combination of LEDs with different spectral composition and the possibility to change the composition of resulting radiation in a single lighting device allows one to improve the efficiency of phytolighting systems and optimize them for different conditions of plant growth and development. In this work, we have investigated quasi-monochromatic LEDs specialized for efficient phytolighting and efficient white LEDs with different CRI. Being based on the research, the most effective LEDs for building phytolighting systems have been identified, and their optimal ratio with red quasi-monochromatic LEDs for building phytolighting systems in rooms with a constant presence of people (greenhouses, winter gardens, etc) has been determined.

优化 LED 植物照明系统的光谱组成,提高能源效率
使用led进行植物照明(植物照明)提供了一种比传统照明方法更节能的选择。不同光谱组成的led组合以及在单个照明设备中改变产生的辐射组成的可能性,使人们能够提高植物照明系统的效率,并针对植物生长和发育的不同条件对其进行优化。在这项工作中,我们研究了专门用于高效植物照明的准单色led和具有不同显色指数的高效白光led。在研究的基础上,确定了用于建筑植物照明系统的最有效的led,并确定了在经常有人的房间(温室,冬季花园等)中用于建筑植物照明系统的红色准单色led的最佳比例。
