What are the components of an SSL system?
SSL is a sophisticated system incorporating a number of different technologies, including: • Power converter: A transformer or power source to convert the mains AC voltage into low DC voltage. • A control system: This may be as simple as an on-off switch, or as complicated as to drive a Las Vegas light show. • Thermal and environmental management: The LED must be protected from moisture, and heat must be effectively dissipated. • Light delivery: This refers to the optics of the sign itself. The design of the sign has an impact on the success of the SSL system. • System integration: All components of the SSL must be integrated and working together. Early failures in the history of the LED resulted more often from failure of components rather than the LED itself.
