摘要： A stage light fixture with an optical parameter detection function includes a light head, a supporting arm and a case. A light source for generating a light path, a light guiding member for guiding light to deviate from the light path, and an optical parameter detector are provided in the light head. The light guiding member can be freely switched into/out of the light path via a driving mechanism. The optical parameter detector can receive and detect the light guided out by the light guiding member. According to the present invention, the light guiding member can be switched into the light path to guide the light to the optical parameter detector for detection, only when the stage light fixture is started to work, or detection is performed at an interval between operations of the stage light fixture, while switched out of the light path when in operation.

摘要： A method for fixing an initial brightness level of lights is provided. Gamma correction is performed on the light based on a dynamic Gamma curve. When a user adjusts brightness of the light based on the dynamic Gamma curve, a dynamic Gamma curve image is valid all the time when a set current brightness level n changes from 0 to N, and when x>0, the dynamic Gamma curve image is continuous, and accordingly, brightness of the light continuously changes gradually. Further, by calculating an initial brightness PWM critical duty ratio D of light sources, the dynamic Gamma curve is customized according to the light, so that an initial brightness level position of the light sources in the same model is fixed and unified.

The pivoting member has at least one light source for generating a lighting effect and is driven to rotate by at least one flat motor. The flat motor includes a stator generating a magnetic field by energization, and a rotor sleeve on the stator and driven by the magnetic field. The pivoting member is fixedly connected with the rotor, and the supporting member is fixedly connected with the stator; or the pivoting member is fixedly connected with the stator, and the supporting member is fixedly connected with the rotor. With respect to the conventional rotating shaft motor, no transmission assembly is provided, a transmission error thus can be avoided to achieve more accurate positioning, and a height of the motor can further be reduced.
