The invention discloses an energy-efficient western philosophy history evolution process instrument, which comprises an electric control box module, a projector body and a PC controller, wherein the electric control box module is provided with a binding post on a side; a projection control chip is installed below the electric control box module; a side of the projection control chip is provided with a memory card interface; the projection control chip is connected to a signal receiver through a signal amplifier, and is connected to the projector body; a player is disposed on the bottom of theprojector body; and the projector body is connected to a projection lens. The energy-efficient western philosophy history evolution process instrument can remotely control a projection operation, andcan switch the projection device into an idle state and switches to a manual blackboard-writing explanation state because it takes a long time to explain the key nodes of the evolution process of thehistory of western philosophy, thereby saving energy. Further, the energy-efficient western philosophy history evolution process instrument integrates functions of sound amplification, remote controland real-time information input, and can provide teachers with all-round teaching assistance.
