基于光谱的光量子学照明系统评价方法，能使现代农业 LED 植物照明系统具有可重复性，从而更有实用意义。本文叙述了传统照明中的光度学、色度学与植物照明中光量子学的异同。引入高出光效率、高均匀度的自由曲面底板设计方法，使用 PWM 驱动方法，结合光量子理论，设计出一款应用自由曲面底板的红蓝 LED 植物照明用灯具并对其进行参数测量。最后以传统照明常用的扩散板为例，分析传统照明设计方法在 LED 植物照明中的意义，并且进行仿真实验，将仿真结果与实际结果进行对比验证。实验结果表明，所设计的灯具具有接近 80%的光量子通量密度均匀度，灯具最高温度在 50℃附近。由于没有使用扩散板等二次配光手段，灯具出光效率可视为 100%，比使用扩散板的情况提高了 34.5%以上，能大大减少植物照明的能耗，节能环保。另外，扩散板的引入会降低灯具的 PPFD 均匀度，而对混光均匀度影响不大，因此我们认为在植物照明中，如自由曲面底板的一次配光方法比扩散板的二次配光方法更具有优势。另外还证明了，在植物照明用的红蓝 LED 组合下，光量子学体系比传统照明的光度学色度学体系更为简便有效，更符合植物照明的设计需求。
Spectral-based light quantum lighting system evaluation method, can make the modern agricultural LED plant lighting system is reproducible, which is more practical significance. This article describes the similarities and differences in photonics in photonics, colorimetry and plant lighting in traditional lighting. The design method of free-form surface with high light efficiency and high uniformity is introduced. By using PWM driving method and light quantum theory, a red-blue LED lighting fixture with free-form surface is designed and its parameters are measured. Finally, the traditional diffusion plate, as an example, analyzes the significance of the traditional lighting design method in LED plant lighting, and carries out simulation experiments, and compares the simulation results with the actual results. The experimental results show that the designed luminaire has an optical quantum flux density uniformity of nearly 80%, and the maximum temperature of the luminaire is around 50 ° C. Since no secondary light distribution means such as diffusion plate are used, the light extraction efficiency of the lamp can be regarded as 100%, which is increased by 34.5% compared with the case of using the diffusion plate, which can greatly reduce the energy consumption of the plant lighting and save energy and environmental protection. In addition, the introduction of diffusion plate will reduce the lamp PPFD uniformity, but little effect on the uniformity of light mixing, so we think that in the plant lighting, such as the free-form surface of a light distribution method than the diffusion plate secondary light distribution method More advantage. In addition, it has also been proved that in the combination of red and blue LEDs for plant lighting, the photon quantum system is simpler and more effective than the traditional photometric colorimetry system and more in line with the design requirements of plant lighting.
