  • Publication number: 20220205621
    Abstract: A stage light fixture with high-accuracy rotary positioning includes a supporting member and a pivoting member pivoted to the supporting member. 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.

  • Publication number: 20220205620
    Abstract: A low-noise reset control system of a light fixture includes a supporting member, a pivoting member and a driver. A limiting portion is arranged on the pivoting member. A blocking portion for limiting a rotation angle of the pivoting member is arranged on the supporting member. The system further includes an angle detector for sensing rotation angle of the supporting member and an angle indicator for sending out indication signal when the pivoting member is at a specific angular position. In a reset process, when the pivoting member rotates in a forward direction until the limiting portion is blocked by the blocking portion, the driver brakes immediately and drives the pivoting member to rotate by a certain angle in a reverse direction at low speed, then to increase speed and continue to drive the pivoting member to rotate in the reverse direction to look for a relative initial position.

  • Publication number: 20220146083
    Abstract: A stage light fixture capable of avoiding lighting in power off includes a light head, a brake motor, an auxiliary power supply, and a controller. The controller is configured to control the brake motor to drive the light head to move to a light-avoiding angle at which strong lighting cannot directly shining into a lighting outlet of the light head and perform power-off processing on the brake motor when the brake motor is switched to be powered by the auxiliary power supply. When the stage light fixture is suddenly powered off, the auxiliary power supply will supply power to the brake motor, and the controller enables a motor unit of the brake motor to drive the light head to move to the light-avoiding angle so as to avoid heat damage to the components inside the light head due to strong lighting irradiation.

  • Patent number: 11255502
    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. 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.
