Abstract

A lamp position adjustment device includes a base plate, a supporting frame, a lamp holder, a first positioning mechanism, and a second positioning mechanism. The first positioning mechanism is disposed between the lamp holder and the supporting frame and between the lamp holder and the base plate to enable the lamp holder to move in a first direction relative to the supporting frame. The first direction is substantially parallel with one side of a light incident surface of an integration rod. The second positioning mechanism is disposed between the lamp holder and the base plate to enable the lamp holder to rotate about an axis parallel to the first direction.
