Battery operated LED light
I need a design for a small rugged battery operated LED light with a wired remote tact switch. Power supply must be 2 serial LR03 - AAA. LED color must be yellow or amber.
Continuous light mode: Upon tact switch input >3 sec. The LED must shine with low intensity (approx. 3 lm) for 10 minutes.
Intermittent light mode: Upon tact switch input <3 sec. The LED must blink with maximum intensity (approx. 20 to 40 lm) for 30seconds (100ms on / 900ms off).
More details in the attached flowchart diagram.
A. Minimal Costs for PCBA (Target <2 USD@10k)
B. Maximum battery livetime
C. Maximum luminosity
