Microwave Lamps For Solar Simulation In Biotron

Biotron由美国国家科学基金会在威斯康星大学建造，是美国首屈一指的研究设施，为植物和动物研究提供精确和独特的环境控制能力。然而，由于当前照明系统提供的光强度不足，Biotron在植物研究中的使用受到了极大的阻碍。我们建议在Biotron的一个房间内安装无极微波灯，以具有有效模拟太阳光光谱的潜力，并提供超过1000 mol m-2 s-1的光合光子通量。这些新灯将评估其在不过度加热的情况下提供这些光子通量水平的潜力，同时研究反射器设计的有效均匀性，灯随时间的退化，以及调光的能力，以小心地降低和提高光子通量水平。我们将编写文件，为在其他需要高光合光子水平的设施中使用这些灯提供信息。

The Biotron, constructed by the National Science Foundation at the University of Wisconsin, is a premier research facility in the United States, providing precise and unique environmental control capabilities for plant and animal research. Use of the Biotron for plant research is significantly hampered, however, by the insufficient light intensities provided by the current lighting system. We propose to install electrodeless microwave lamps in one room of the Biotron to have the potential of effectively simulating the sunlight spectrum and providing in excess of 1000 mol m-2 s-1 of photosynthetic photon flux. These new lamps will be evaluated for their potential to provide these photon flux levels without excessive heating along with study of reflector design for effective uniformity, lamp degradation over time, and capability for dimming to carefully lower and raise photon flux levels. We will develop documentation to provide information for utilization of these lamps in other facilities needing high photosynthetic photon levels.
