Potential advantages offered by multichannel luminaires with regards to spectral tuning are frequently overshadowed by its design challenges, a major one being the non-uniformity in illuminance and color distribution. In this paper, we present a formulation using genetic algorithm (GA) to optimize the Light Emitting Diode (LED) placement, yielding 40% superior uniformity in illuminance and color distributions compared to existing analytical formulations, substantially reducing the reliance on optical design for this purpose. It is specifically shown that our approach is employable for circadian tuning applications, even when heavily constrained by industry specifications on panel size and minimum LED separation.
多通道灯具在光谱调谐方面的潜在优势常常被其设计挑战所掩盖，其中一个主要挑战是照度和颜色分布的不均匀性。在本文中，我们提出了一种使用遗传算法（GA）来优化发光二极管（LED）布局的方法，与现有的解析方法相比，该方法在照度和颜色分布上的均匀性提高了40%，从而大幅减少了在此方面对光学设计的依赖。具体表明，即使在受到面板尺寸和最小LED间距的行业规范严重限制的情况下，我们的方法也可用于昼夜节律调谐应用。
