The present invention relates to a projecting effect adjusting device containing at least a optical module that can change the LED projecting effects. The projecting effect adjusting device has the function of two-dimensional displacement and fixed-point locating using a displacing control module and a locating module. The said two-dimensional displacement allows at least the linear displacement of the projecting effect adjusting device between the first position and the second position. The fixed-point locating allows at least the projecting effect adjusting device to be located on the first position and the second position. The first position is set to keep a distance between the optical module and the LED matrix light source and the second position is set between the optical module and the light-emitting plane of the LED matrix light source. |
