Problems solved by technology

There are many ways to adjust the illumination angle of spotlights, such as manual adjustment, motor-driven adjustment, etc., but in the prior art, no matter what the method is, there is a dead angle to adjust the illumination angle, that is, 360° free adjustment cannot be realized. in order to avoid winding
The existing spotlights powered by mains power need to be electrically connected to the line of the mains, and the length of the wire reserved is limited. When the beam angle of the lamp can be adjusted by 360°, it is easy to be damaged by the line during the adjustment process. A short circuit occurs due to winding, so the adjustment range of the beam angle of the spotlight in the existing design is mostly limited to within 350°
In addition, in the existing design, the rotating components used to adjust the beam angle are mostly fixed together with screws, which is also very inconvenient to disassemble and replace

Embodiment 1

[0037] Refer to attached figure 1 to attach Figure 4 , the present embodiment provides a magnetic rotation assembly for adjusting the beam angle, which includes a motor fixing part 11, a motor 12, a driving gear 13, a driven gear 14, a DC plug 15 and a magnetic buckle 16, the above-mentioned motor fixing part 11 A shaft hole 115 is opened on the top, and the above-mentioned motor 2 and the above-mentioned driving gear 13 are respectively located on both sides of the above-mentioned motor fixing member 11. The output shaft 121 of the above-mentioned motor 12 passes through the above-mentioned shaft hole 115 and is installed and matched in the mounting hole 131 in the center of the driving gear Inside, the above-mentioned driving gear 13 can be rotated under the driving of the above-mentioned motor 12; the above-mentioned driven gear 14 and the above-mentioned motor fixing member 11 are detachably plugged in, and when the two are inserted and fixed, the above-mentioned driven g...

Embodiment 2

[0046] Another object of the present invention is to provide a spotlight using the magnetic rotating assembly.

[0047] Refer to attached Figure 5 And attached Figure 6 , a spotlight, including an electrical box 2, a lamp body 3 and a magnetic rotation assembly 1 for adjusting the beam angle provided by the present invention, the motor fixing part 11 is installed and fixed on the electrical box 2, and the driven gear 14 is fixed on the lamp body 3. The installation method in this embodiment is to use screws to fix, of course, other fixing methods are also available, using known buckles, embedded buckles, etc., which will not be repeated here.

[0048] Refer to attached Figure 6 , in this embodiment, the magnetic rotation assembly used to adjust the beam angle is different from Embodiment 1. It is provided with a boss 141 on the motor fixing part 11, and correspondingly provided with a corresponding Groove (not marked on the picture).

[0049] In this embodiment, the la...

Abstract

The invention relates to the field of illumination, in particular to a magnetic attraction rotating assembly for adjusting the angle of a light beam and a spotlight using the magnetic attraction rotating assembly. The assembly comprises a motor fixing part, a motor, a driving gear, a driven gear, a DC plug and a magnetic buckle, the motor drives the driving gear to rotate, the driven gear is detachably connected with the motor fixing part in a pluggable mode, and when the driven gear and the motor fixing part are inserted and fixed, the driven gear is meshed with the driving gear, so that thedriven gear can rotate along with rotation of the driving gear; the DC plug comprises a DC male plug and a DC female plug, one of the two plugs is fixed at the center of the driven gear, and the otherone is fixed at the corresponding position of the motor fixing piece, so that the two plugs are also inserted and conducted when the driven gear and the motor fixing piece are inserted and fixed; themagnetic buckle comprises at least two magnetic materials which can be attracted to each other, one magnetic material is arranged on the driven gear, and the other magnetic material is correspondingly arranged on the motor fixing piece. By means of the structure, winding in the rotating process can be avoided, and the irradiation angle can be adjusted by 360 degrees.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a magnetic rotation assembly for adjusting the beam angle and a spotlight using the same. Background technique [0002] The focused beam of the spotlight is especially suitable for specific situational lighting. There are many ways to adjust the illumination angle of spotlights, such as manual adjustment, motor-driven adjustment, etc., but in the prior art, no matter what the method is, there is a dead angle to adjust the illumination angle, that is, 360° free adjustment cannot be realized. It is to avoid the situation of winding. The existing spotlights powered by mains power need to be electrically connected to the line of the mains, and the length of the wire reserved is limited. When the beam angle of the lamp can be adjusted by 360°, it is easy to be damaged by the line during the adjustment process. A short circuit occurs due to winding, so the adjustment range of the beam angle o...
