Semiconductor Lamp Usage TRIZ Cases
- Luminaire SPD Failure Indication Through External LED Monitoring
Visible LED indication linked to SPD monitoring lets luminaire maintenance teams detect surge protection failure without opening the housing.
- Solid-State Circuit Protection With AC-DC Conversion for Hazardous DC Loads
Arc-free solid-state protection combines AC-DC conversion and load control to power hazardous-location DC loads with less heat, space, and enclosure complexity.
- LED Module Current Control to Avoid Overcurrent Shutdown
A control module adjusts LED conduction after overcurrent detection, keeping lighting active and signaling power-spec mismatches.
- Solid-State Circuit Protection for Hazardous DC Lighting Loads
Arc-free solid-state switching and centralized AC-DC conversion protect hazardous-location LED loads while removing internal converters.
- LED Current Source Control Using Reference Modulation Against EMI Flicker
Reference current modulation below the control loop corner frequency suppresses EMI-driven LED flicker while keeping light output stable.
