Why do led and smd lamps and corporate projectors break down and burn?

As you know, led and smd lamps and projectors may break down and burn after long use for 1 to 2 years, and the interesting thing is that this happens as soon as the warranty period and date expires. Why? How does this happen after 1 year? Why does it work for 1 year?
