The invention relates to a rotating lamp and a reset control circuit thereof. The reset control circuit comprises a position detection part, a control part and a driving part, wherein the position detection part is used for detecting the current position of the rotating lamp; the control part is used for outputting a reset control signal according to the current position of the rotating lamp; the driving part is used for driving the rotating lamp to reset according to the reset control signal; the rotating lamp is provided with a rotating shaft; a rotating iron block is installed on the rotating shaft and provided with a semicrcular hole which is matched with the rotating shaft; the rotating iron block passes through the shaft line of the rotating shaft in the direction which faces the end surface of the rotating shaft; and the position detection part comprises a magnetic induction proximity switch which judges the position of the rotating lamp according to the position of the rotating iron block. With the technical scheme, because a plurality of points can be detected in the rotating process of the rotating iron block, the case of misjudgment caused by inaccuracy of detection through point trigger can be avoided.
Description
technical field [0001] The invention relates to lighting control technology, more specifically, to a rotating lamp and a reset control circuit thereof. Background technique [0002] In daily life, with the popularity of rotating lamps, the positioning of lamps is also required to be more and more precise. With the development of intelligence, almost all lamps that can control the direction of irradiation need to have a reset function. There are also many automatic reset control schemes on the market. For example, the push-button trigger reset adopted earlier, this reset method is simple in design, but this reset method has relatively high requirements on the sensitivity and life of the button, because the sensitivity of the button is directly related to the performance of the entire lamp, and the function of the button Life is directly related to the life of the entire lamp. Now there is still a more widely used reset method, which is photoelectric scanning detection meth...
