Very interesting. LED's thermal concerns can make it quite complicated.

"With LED lights, the LED is the source of light and the heat generated by the LED is in direct contact the LED light bulb..." LED's are not "light bulbs", they are chips or dies. "The direct contact is a result of how the LEDs have to be attached to the driver circuit..." It has less to do with how the LED's have to connect (not attach) to the driver circuit and more with practical aspects of getting the heat out.

what is wrong with using a simple control loop to control the LED current so the LED is operating at a safe temp? No need for the red LED and measuring lumens, etc. your approach is too complicated.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
