Abstract: A stage light having an effect element made of a ceramic material comprises a light source, an effect element, and a driving component connected to the effect element. The light emitted by the light source forms a light beam, the effect element is made of a ceramic material, and the driving component drives the effect element to rotate or move relative to the light beam so as to enable the light beam to generate a corresponding lighting effect.

Since ceramic is less susceptible to thermal deformation and has a higher temperature resistance than metal, making the effect element with a ceramic material can effectively reduce thermal deformation and cracking, thereby prolonging the service life of the effect element.
