LED video

This was in Lumiled's recent newsletter. It's an engineering-level discussion of their high-power LEDs and related concepts, although it's very basic in content. Worth watching though.

I think the second installment is due in Juanuary. Let's hope they raise the technical content a bit in the second episode.

Very basic but interesting nevertheless. Watched until 13', this evening continuing

One thing I learned is growing plants using RGB or just (R+B) leds is pointless. As Carson used to say, I did not know that.

The second installment of this series is here:

Discussion topics are:

- Constant current regulators & PWM
- Driving RGBs
- Thermal simulation (using QLED)
- Circuit design using WebBench

Overall, I thought it was well worth watching.
