360-degree full-angle wide-area scanning head

Abstract

The invention discloses a 360 degree full angle wide area scanning head consisting of a photoelectric assembly and a driving assembly. The photoelectric assembly comprises a vertical light source, a horizontal light source, a semi-transparent and semi-reflective mirror, a total reflective mirror group and a field lens. The driving assembly comprises a vertical driving electric motor, a horizontal driving electric motor, a first driver, a second driver, a vertical rotating shaft, a horizontal rotating support rack, a vertical rotating bevel gear and a horizontal rotating bevel gear. An upper end of the horizontal rotating support rack is provided with a horizontal rotation driving rod having a shaft hole, a lower end of the horizontal rotating support rack is a total reflective mirror group installation cover, a lower end of the vertical rotating shaft extends into the total reflective mirror group installation cover, the vertical rotating bevel gear is arranged in the total reflective mirror group installation cover in pivoted manner after being connected with the lower end of the vertical rotating shaft, the horizontal rotating bevel gear is arranged in the total reflective mirror group installation cover in a pivoted manner via a horizontal rotating shaft mounted on a side wall of the total reflective mirror group installation cover, the total reflective mirror group is fixed on the horizontal rotating shaft, and the vertical rotating shaft and the vertical rotating bevel gear are provided with central light holes. Via the 360 degree full angle wide area scanning head, lamp light scanning breadth, speed and precision can be increased.

Description

technical field [0001] The invention relates to the technical field of lighting scanning equipment, in particular to a 360-degree full-angle wide-area scanning head. Background technique [0002] The existing scanning head adopts the dual vibrating mirror method, that is, the vibrating mirror 1 rotates around the horizontal axis and the space disjoint vibrating mirror 2 rotates around the vertical axis. The superposition of the two vibrating mirrors realizes scanning within a certain area. The size of the scanning area is determined by The size of the lens is determined, and the zoom is realized by the field lens. To realize a wide range of scanning, the size of the vibrating mirror must be increased, that is, the quality of the vibrating mirror will increase, and the required space will increase. This will bring great inconvenience to the motor driving the vibrating mirror. The large burden leads to the inability to improve the accuracy and speed of the galvanometer movemen...

[0002] The existing scanning head adopts the dual vibrating mirror method, that is, the vibrating mirror 1 rotates around the horizontal axis and the space disjoint vibrating mirror 2 rotates around the vertical axis. The superposition of the two vibrating mirrors realizes scanning within a certain area. The size of the scanning area is determined by The size of the lens is determined, and the zoom is realized by the field lens. To realize a wide range of scanning, the size of the vibrating mirror must be increased, that is, the quality of the vibrating mirror will increase, and the required space will increase. This will bring great inconvenience to the motor driving the vibrating mirror. Large burden, resulting in the inability to improve the accuracy and speed of the galvanometer movement, resulting in the inability to improve the scanning accuracy and speed, and it is difficult to expand the scanning range

At present, light scanning heads are widely used in optical application control occasions such as stage lights, laser marking, and printing, and these scenes often have great requirements for scanning range, and it is difficult for existing scanning heads to achieve full-angle wide-area scanning
