If you wish to take a course to receive a certificate, you must take the course under "Online Courses". Do NOT take the course here under "Materials By Topic" as you would not receive a certificate for completing the materials here. The "Materials By Topic" content is intended just for reference purposes.

This course covers the technology and packaging associated with Light Emitting Diodes (LEDs) and Solid State Lighting (SSL).  We cover the basics of LED operation, the market trends associated with LEDs and SSL installations.  We also cover the manufacturing process along with the packaging and assembly process.  We pay special attention to thermal dissipation topics, since many SSL applications use high power LED chips that dissipate significant heat.  We also discuss reliability and testing of these products.
