HI,
How i can improve life of LED,is it possible to increase life by reducing current to 10mA, and what minimum current I can give to LED to glow??
 

There are some basic ways to improve LED life:
- Reduce operating temperature
- Reduce current
- Allow good thermal dissipation
- Protect LED against ESD (this causes premature failures)
- Use good quality- long life - LEDs, typically not the cheapest ones
- Follow manufacturer soldering instructions... some LEDs require a drying oven before being soldered, some have some soldering temperature limitations...

Regarding minimum current, it depends on the LED exact model, but you may find LEDs that glow with 1 mA or less!
