Hello all,
I'm new here and new to electronics in general. I am an artist and architect very humbly asking for your advice. If this type of inquiry is not welcome on your forum, I apologize.
I want to create a completely sealed block of resin internally lit by a battery powered LED circuit that lasts as long as is currently possible. I'm shooting for years. It should be about the size of a beer can and provide enough light to read by if held very close to the page. Is this possible? I have found examples of this being done in the past but with no stated life expectancy. How could I roughly calculate this? How long do you think an optimally designed circuit might last?
potential problems:
-I understand the heat damages LEDs over time. Encasing the circuit in resin may accelerate this as the plastic will inevitably retain the heat generated by the light. Is this actually a problem? How might I mitigate it?
-From what I have read, LEDs never truly burn out but rather slowly dim. For my purposes, it would be best if the bulb died fairly suddenly. Could I create a circuit that switches off or self destructs when a specified low level of power consumption is reached?
Any comments would be greatly appreciated. Thanks!
