在固态照明产品的设计中，通常没有充分考虑LED工作的温度依赖性。如果没有仔细考虑温度的依赖性，固态照明产品通常被过度设计为在任何可能的环境条件下都足以满足要求。不过，如果考虑得当，LED的温度依赖性甚至可能是一个新的优势。过度设计意味着在LED效率/效能较低的情况下，设计最坏的情况，即可能的最高环境温度。由于在较低的温度下，由于效率/效率的提高，电功率降低，因此，较低的正向电流水平就足够了，因此，通过控制方案，可实现恒定的总发光通量，从而实现显著的电功率节约。我们提出了新的，所谓的iso通量控制方案及其在实际智能灯具中的实现。 采用多域LED模型设计了实际控制方案，并通过仿真验证了控制结果。

Temperature dependence of LED operation is often not fully considered during the design of solid state lighting products. If temperature dependence is not carefully considered, solidstate lighting products are typically overdesigned to be too robust enough to fulfil the requirements under any possible environmental conditions. Temperature dependent nature of LEDs though, could even be a new benefit if properly considered. Overdesign means designing for the worst case that is the highest possible environmental temperature when LED efficiency/efficacy is low. With a control scheme resulting in constant emitted total luminous flux significant electrical power saving can be achieved since at lower temperatures, due to increasing efficiency/efficacy less electrical power, thus, lower forward current levels are sufficient. We present the new, so called iso-flux control scheme and its implementation in an actual smart luminaire. The actual control scheme was designed with a multi-domain LED model and the results were validated by simulation.
