This invention provides a multi-directional illumination simulation device for edible mushroom cultivation. It includes a movable frame with a lifting cylinder mounted on it. A mounting plate is slidably installed inside the frame, and a motor is mounted above the mounting plate. A light is installed at the output end of the motor, which is connected to a gear via a belt drive mechanism. In this invention, by setting up a transmission mechanism, when the motor drives the light to rotate, it drives the reflectors to rotate in the opposite direction along the axis. Utilizing the rectilinear propagation characteristic of light, the light is effectively reflected to the shaded area of ​​the mushroom spawn, achieving multi-directional illumination and effectively eliminating growth differences caused by uneven light exposure, ensuring upright growth of the mushrooms. Furthermore, by rotating the threaded sleeve, the tilt angle of all reflectors can be adjusted simultaneously, flexibly controlling the direction of light reflection to meet the light requirements of different growth stages, making it practical and easy to operate.
