A light bulb assembly with reduced tolerance for engaging a light bulb to a light engine. The light bulb has a first positioning portion. The light bulb assembly has a light machine and a light bulb frame. The light machine has a second positioning portion and an engaging portion for fixing the light bulb in a determined position when the first positioning portion of the light bulb abuts the second positioning portion. The light bulb frame is relatively fixed to the light machine for supporting the light bulb; the light bulb frame has a leaning portion for leaning on the first positioning portion of the light bulb, and an elastic pressure portion for applying three-dimensional pressure on the light bulb for moving toward the determined position.
