A lighting effect adjustment system includes a light source module, and a focusing module, a magnification module and a light output lens that are arranged in sequence along a beam projection direction of the light source module. The focusing module, the magnification module and the light output lens are mounted on a stage light holder, The focusing module and the magnification module are independently slidable in a light path direction. An effect module is further slidably arranged between the focusing module and the light output lens. The effect module includes one or more effect sheets configured to be switched into and out from a light path, and motions of the effect module and the magnification module are independent without interference with each other.

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. The stage light having an effect element made of a ceramic material has abundant effects by the effect element made of a ceramic material. 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.

A method for appreciating water balls using a water balls appreciation device, including a water balls discharge device and a light irradiation device, the method including: discharging the water balls, using the water balls discharge device, from tips of a plurality of nozzles, disposed at predetermined intervals in the lateral direction, by applying vibration to flowing water, the discharged water balls falling downwardly and in substantially a vertical plane; irradiating the water balls, using a light irradiation device, with light, the light irradiation device comprising a high-speed projector having a refresh rate of 300 Hz or more; and projecting a continuous screen of the projector in the water balls in the vertical plane regarded as a virtual screen by properly using a frame displaying a screen or an image and a frame not displaying a screen, so that a blinking duty is 20% or less, whereby the water balls are visually appreciated in the projected area. Then, by changing the timing of light emission for passing light through the image, it is possible to appreciate the movement of the water balls that changes in various manners.
