As a Star starts to collape its gravitational field at the surface becomes stronger and the escape velocity increases. The escape velocity increases to 300.000kps. the velocity of light. After that time any light emitted from the Star would not be able to escape and would be dragged back by its own gravitational field..As special Theory of Relativity says "nothing can travel faster than the speed of light" so if its light cannot escape, nothing else can. the result..A black hole
