If cost were less of a concern, what engineering changes would you make to the bulb?

- phasetransition 8y ago#1 more die. More die means less current per die, which helps efficacy in a nonlinear way (google "LED droop") #2 better passives. Aluminum polymer caps, for instance #3 lower temps, in however you want to achieve that aim #4 some TVSS element if there wasn't one already
- xxs 8y agoThere: 1) Better cooling: non-tooth paste thermal compound, more space for heatsinks 2) Not overdriven LEDs 3) Introduce DC power lines (within the house/building) - galvanic corrosion still might be an issue 4) In lack of point 3 - more efficient AC -> DC converters, preferably with lower temp threshold, having 150C default for the internal mosfet on 8pin LED driver is really high. 4a) AC-DCs require quality passive components: coil and caps.
