| Title: |
Low-Noise Reset Control System of light Fixture |
| 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 pivoting 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. |
