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


1. Schematic layout incl. livetime and cost calculations

Taidot: Piirilevyn asettelu
