A projection apparatus, a power management apparatus, and a method for power management thereof are provided. The projection apparatus has a first power socket corresponding to a first power specification and a second power socket corresponding to a second power specification. The second power specification is different from the first power specification. A voltage detection unit is adapted to detect an input voltage received by a powered power socket, wherein the powered power socket is the first power socket or the second power socket. A control unit decides whether the input voltage detected by the voltage detection unit is matched up with the power specification of the corresponding powered power socket to determine an operation mode of the projection apparatus and to determine whether the projection apparatus provides an alarm message to ensure safety of use.

A lamp position adjustment device includes a bottom frame, a lamp holder, and a lamp mount. The lamp holder is disposed on the bottom frame for supporting the lamp, and the lamp mount is disposed between the lamp holder and the bottom frame. The lamp mount includes a base portion, a first side portion and a second side portion that are respectively connected to two opposite sides of the base portion, a first positioning mechanism, and a second positioning mechanism. The first positioning mechanism is disposed on the base portion to enable the lamp mount to be slidably connected to the bottom frame, and the second positioning mechanism is disposed on the first side portion and the second side portion to enable the lamp mount to be slidably connected to the lamp holder.
