[0002] The light projection lamp makes the illuminance on the designated illuminated surface higher than the surrounding environment, and is also called a spotlight, usually, it can aim at different directions, and has a structure not affected by weather conditions, and is mainly used for large area operation fields, building outlines, sports fields, overpasses, monuments, parks and flower beds.

[0003] The existing light projection lamp needs to adjust the light transmission and irradiation angle when lighting, and the existing adjustment of the irradiation angle of the light projection lamp is generally completed by relying on a damping hinge.

[0004] The existing technology relies on a damping hinge to adjust the light transmission and irradiation angle, and the damping hinge is not firm enough, which affects the normal use of the light projection lamp to a certain extent, and therefore a light projection equipment for lighting engineering is proposed.

At this time, the guide side groove can rotate around the annular guide block. According to the position of the scale reading on the right end of the annular guide block where the indicator block is located, the rotation angle of the mounting shaft can be determined, thus achieving precise adjustment of the lamp head rotation angle. When adjusting the lamp head angle, the electromagnet is activated. The electromagnet attracts the iron positioning head, causing the upper end of the iron positioning head to separate from the annular magnet, allowing the mounting shaft to rotate smoothly. At this time, the spring is in a compressed state. When the lamp head angle is adjusted to the appropriate position, the electromagnet is turned off, and the spring returns to its original deformation, driving the iron positioning head to move and re-attract the iron positioning head to the annular magnet, thus repositioning the mounting shaft.

Therefore, they should not be construed as limitations on this utility model.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] like Figures 1-3 As shown, this utility model embodiment provides a floodlighting device for lighting engineering, including a base 1, a mounting shaft 2, a lamp holder 6 and a lamp head 5. A left mounting side plate 4 and a right mounting side plate 7 are symmetrically fixedly installed on the upper end of the base 1, and the left mounting side plate 4 is located to the left of the right mounting side plate 7.

[0043] The mounting shaft 2 is set in a horizontal direction, and the left and right ends of the mounting shaft 2 pass through the left mounting side plate 4 and the right mounting side plate 7 respectively. The left mounting side plate 4 and the right mounting side plate 7 are rotatably connected to the mounting shaft 2 through bearings. The lamp holder 6 is fitted on the mounting shaft 2, and the lamp holder 6 is located between the left mounting side plate 4 and the right mounting side plate 7. The lamp head 5 is fixedly installed on the upper end of the lamp holder 6.

[0044] The angle of the lamp holder 6 can be adjusted by mounting shaft 2, which facilitates the adjustment of the illumination angle of lamp head 5.

[0045] In this embodiment, a torsion handle 3 is also included, which is fixedly fitted onto the left end of the mounting shaft 2.

[0046] The mounting shaft 2 can be rotated by the torsion handle 3, thereby adjusting the illumination angle of the lamp head 5.

[0047] It also includes an annular positioning block 8, an indicator block 1001, and an annular guide block 9. The annular positioning block 8 is fixedly installed on the right end of the right mounting side plate 7 and is located outside the right end of the mounting shaft 2. The indicator block 1001 is fixedly installed on the upper end face of the right end of the mounting shaft 2 and is located on the right side of the right mounting side plate 7. The annular guide block 9 is fixedly installed on the right end of the right mounting side plate 7 and is located inside the annular positioning block 8 and outside the mounting shaft 2. The indicator block 1001 is fitted onto the annular guide block 9.

[0048] It also includes a scale display and a guide side groove 1005. The scale display is located at the right end of the annular guide block 9, and the guide side groove 1005 is opened at the left end of the indicator block 1001. The guide side groove 1005 is slidably connected to the annular guide block 9.

[0049] When the torsion handle 3 adjusts the illumination angle of the lamp head 5, the mounting shaft 2 rotates. The rotating mounting shaft 2 can drive the indicator block 1001 to rotate. At this time, the guide side groove 1005 can rotate around the annular guide block 9. According to the position of the scale reading on the right end of the annular guide block 9 where the indicator block 1001 is located, the rotation angle of the mounting shaft 2 can be determined, thereby achieving precise adjustment of the rotation angle of the lamp head 5.

[0050] It also includes a positioning mechanism, which includes an iron positioning head 1002. The iron positioning head 1002 is installed on the upper end of the indicator block 1001, and the upper end of the iron positioning head 1002 is detachably fixed to the inner wall of the annular positioning block 8.

[0051] The positioning mechanism also includes an annular magnet block 1003, which is embedded and fixedly installed on the inner wall of the annular positioning block 8, and the annular magnet block 1003 is magnetically attracted to the iron positioning head 1002.

[0052] like Figures 2-4 As shown, the positioning mechanism also includes an upper mounting groove 1006, an electromagnet block 1007, and a return spring 1004. The upper mounting groove 1006 is opened at the upper end of the indicator block 1001. The electromagnet block 1007 is fixedly installed at the bottom inside the upper mounting groove 1006 and is located directly below the iron positioning head 1002. The lower end of the return spring 1004 is connected to the bottom inside the upper mounting groove 1006. The return spring 1004 is sleeved on the outside of the electromagnet block 1007. The upper end of the return spring 1004 is fixedly connected to the lower end of the iron positioning head 1002.

[0053] The magnetic attraction force of the electromagnet block 1007 to the iron positioning head 1002 is greater than that of the annular magnet block 1003 to the iron positioning head 1002. This design facilitates the electromagnet's successful attraction of the iron positioning head 1002, allowing the iron positioning head 1002 to be easily separated from the annular magnet block 1003.

[0054] When the angle of the lamp head 5 is adjusted, the electromagnet block 1007 is activated. At this time, the electromagnet block 1007 attracts the iron positioning head 1002, thereby separating the upper end of the iron positioning head 1002 from the annular magnet block 1003, so that the mounting shaft 2 can be rotated smoothly. At this time, the spring is in a compressed state.

[0055] After the lamp head 5 is adjusted to the appropriate position, the electromagnet is turned off. The spring returns to its original deformation and moves the iron positioning head 1002, so that the iron positioning head 1002 is re-attracted to the annular magnet block 1003, thereby realizing the repositioning of the mounting shaft 2.

[0056] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
