Figure 6
Near the left-center, a darkly highlighted node labeled “E E-01” appears as a focal element. Above “E E-01” is a node labeled “S R-01”. Below “S R-01” is a node labeled “E E-02”. “S R-01” connects to “E E-02”. “E E-02” connects downward to “E I-01”. “E I-01” connects upward to “E E-01”. To the right of “E I-01” is a node labeled “E I-02”. “E E-01” curves downward to “E I-02”. “E I-02” connects rightward to “O S-01”. “O S-01” connects upward to “I R-01”. “I R-01” curves upward and connects to “S R-01”.Reinforcing feedback loop involving EE-01 (energy efficiency) in LED airfield lighting systems.
