A low-noise light fixture reset structure, comprising: a pivot shaft; and a pivot member rotatably connected to the pivot shaft, wherein the pivot member has a first rotation direction and a second rotation direction that are opposite in direction relative to the pivot shaft, the pivot shaft is connected with a fixed drive wheel relative to the pivot shaft and is sleeved with a shifter lever that is capable of freely rotating relative to the pivot shaft; a first detection marker is provided on the shifter lever, and a first detector configured to detect the first detection marker is correspondingly provided on the pivot member; a first limiting post configured to limit the shifter lever is also provided on the drive wheel, the pivot member is further provided with an elastic member capable of resisting against the shifter lever and a second limiting post configured to limit the shifter lever, an resisting end of the elastic member and the second limiting post are respectively located on two sides of the first detector, the second limiting post, the first detector and the resisting end are sequentially provided in the first rotation direction, and the second limiting post, the elastic member and the first limiting post do not interfere with each other during a relative movement between the pivot member and the pivot shaft; and when one side of the shifter lever is blocked by the first limiting post and the other side of the shifter lever squeezes the elastic member, the elastic member deforms to the second rotation direction to cause the first detector to detect the first detection marker on the shifter lever. a pivot shaft; and a pivot member rotatably connected to the pivot shaft, wherein the pivot member has a first rotation direction and a second rotation direction that are opposite in direction relative to the pivot shaft, the pivot shaft is connected with a fixed drive wheel relative to the pivot shaft and is sleeved with a shifter lever that is capable of freely rotating relative to the pivot shaft; a first detection marker is provided on the shifter lever, and a first detector configured to detect the first detection marker is correspondingly provided on the pivot member; a first limiting post configured to limit the shifter lever is also provided on the drive wheel, the pivot member is further provided with an elastic member capable of resisting against the shifter lever and a second limiting post configured to limit the shifter lever, an resisting end of the elastic member and the second limiting post are respectively located on two sides of the first detector, the second limiting post, the first detector and the resisting end are sequentially provided in the first rotation direction, and the second limiting post, the elastic member and the first limiting post do not interfere with each other during a relative movement between the pivot member and the pivot shaft; and when one side of the shifter lever is blocked by the first limiting post and the other side of the shifter lever squeezes the elastic member, the elastic member deforms to the second rotation direction to cause the first detector to detect the first detection marker on the shifter lever.
