    Abstract: A capacitance type rotation angle detection stage light includes a pivoting member and a supporting member for supporting the pivoting member. A reflecting grating is attached on the pivoting member, and the reflecting grating rotates along with the pivoting member. A signal grating is attached on the supporting member. The signal grating and the reflecting grating are arranged oppositely. The signal grating comprises capacitance emitting pieces, a capacitance receiving piece and shielding pieces. The reflecting grating comprises capacitance reflecting pieces that reflect signals sent from the capacitance emitting pieces to the capacitance receiving piece. Periodic excitation signals applied to the capacitance emitting pieces finally form a composite signal on the capacitance receiving piece through coupling of two pairs of capacitors that the capacitance emitting pieces and the capacitance reflecting pieces, and the capacitance reflecting pieces and the capacitance receiving piece.

    Abstract: A variable frost system (100) includes a first arm assembly (102) that includes a first arm structure (114), a first frost component (116), and a second frost component (118), where the first frost component (116) and the second frost component (118) are attached to the first arm structure (114). The variable frost system (100) includes further a second arm assembly (104) that includes a second arm structure (120), a third frost component (122), and a fourth frost component (124), where the third frost component (122) and the fourth frost component (124) are attached to the second arm structure (120). The first arm assembly (102) and the second arm assembly (104) are movable such that one or both of the first frost component (116) and the second frost component (118) and one or both of the third frost component (122) and the fourth frost component (124) are positioned to provide an overall frost lighting effect to a light beam (206).

    Abstract: A stage light fixture having light effect elements server includes a light source arranged in a light head for generating a light beam, effect sheets for generating a light effect, at least one light effect elements server for receiving the effect sheets, and at least one moving mechanism for extracting at least one of the effect sheets from the light effect elements server to move between the light effect elements server and the light beam, and can keep the extracted effect sheet in the light beam. According to the present disclosure, the moving mechanism may not always occupy the space in the direction of the light path of the light beam, but only temporarily occupy the space in the direction of the light path when the effect sheet is moved to the light path, the space thus can be fully utilized.

    Abstract: The systems herein include a support structure and multiple light sources mounted to the support structure. The light sources are configured to project light onto a recording stage to light a specified video scene that is to be recorded on the recording stage. These systems also include a perforated layer that includes an arrangement of apertures. The perforated layer has an inward face directed toward the lighting sources and an outward face directed toward the recording stage. The inward face of the perforated layer includes a surface layer that is more reflective than the surface layer of the outward face of the perforated layer. These systems also include a controller that modifies the light emission profile of the light sources, including changing color balance, brightness, time dependence, and/or spatial variation over the light emissive surface of the light sources. Various other apparatuses and recording stage devices are also disclosed.
