| Title: |
Stage Light Fixture with High-Stable Rotational Positioning |
| Abstract: |
A stage light fixture with high-stable rotational positioning including a base, a pivoting arm pivoted to the base through a pivoting shaft, and a light head pivoted to the pivoting arm through another pivoting shaft. An angular detector for detecting a rotation angle of the light head and/or the pivoting arm is further provided, which includes a stator assembly and a rotor assembly oppositely arranged each other, wherein the stator assembly has a magnet exciting coil adapted to form an alternating magnetic field in a region of the stator assembly by high-frequency periodic alternating current and voltage and a receiving coil arranged in the alternating magnetic field adapted to form an induced electromotive force; and the rotor assembly is configured to change electromagnetic coupling strength between the magnet exciting coil and the receiving coil during rotation thereof relative to the stator assembly. |
