Abstract: A TLQ Protection Module (106) for Temporal Light Quality (TLQ) protection in an LED luminaire (100), configured to be positioned inline in a Direct Current (DC) current path between the LED driver (104) and an LED engine (108), comprises a current sensing (202) stage generating a voltage signal V_SENSE (250), a frequency- weighted evaluation (204) stage having a broadband first channel (206) and a low-frequency second channel (208) evaluated against threshold references (210), and an OR Logic (212) element generating a breach signal upon threshold exceedance. An autonomous protection response (214) stage reduces current to a Safe Operating Level (SOL) (602) upon breach, continuously re-assesses current quality, and operates in a normal operation (400) state, a distress hold (408) state, or a fault (412) state. The TLQ Protection Module (106) operates without electrical communication with or modification to the connected LED driver (104). [Figure 1]
