Technical Field

[0001] The utility model relates to the technical field of lighting mechanisms, in particular to a shadow-eliminating lighting mechanism. Background Art

[0002] During the operation, a shadowless lamp will be used for lighting. The shadowless lamp has a large diameter single hole or multi-hole structure. The size of the lamp holder determines the installation position of the light source. The larger the installation diameter of the light source and the larger the emitting source area of ​​the light source, the larger the shadowless area formed on the surgical work surface and the better the shadowless effect.

[0003] After searching, the patent publication number CN217525397U discloses a "main-auxiliary operating room shadowless lamp", which includes a main body and an adjustment component for adjusting the irradiation height of the main body.

At the same time, a plurality of sliders are moved in an annular groove to establish a connection between the turntable and the base, and the turntable has a certain rotation range. Therefore, the small shadowless lamp can be held by hand and rotated to a certain angle to change the irradiation angle and range of the small shadowless lamp. The position of the small shadowless lamp can be changed according to different body positions.

A slide 206 with a first magnetic sheet 208 mounted on its top is movably inserted into the notch 209. The first magnetic sheet 208 and the second magnetic sheet 211 are correspondingly engaged.

[0024] Under the action of the first magnetic sheet and the second magnetic sheet, when the small shadowless lamp is in use, the slide plate can be pulled out to separate the first magnetic sheet and the second magnetic sheet. When the small shadowless lamp is finished using, the slide plate is returned to its place, and the small shadowless lamp is rotated in the opposite direction. The small shadowless lamp can be fixed by the adsorption of the first magnetic sheet and the second magnetic sheet, thereby achieving a reset effect, which is convenient for adjusting the lighting auxiliary mechanism next time.

[0029] A plurality of sliders 202 are disposed between two adjacent first magnetic sheets 208 .

[0030] Example 2: A shadow-eliminating illumination mechanism, comprising: a shadowless lamp body 1 mounted on the bottom of a base 204; a turntable 201 disposed above the base 204; a small shadowless lamp 3 disposed obliquely on one side of the shadowless lamp body 1; and a connecting arm 4 fixedly connected to the turntable 201.

A slide 206 with a first magnetic sheet 208 mounted on its top is movably inserted into the notch 209. The first magnetic sheet 208 and the second magnetic sheet 211 are correspondingly engaged.

[0032] On the basis of reducing the blind area of ​​irradiation, the connecting arm drives the small shadowless lamp to move along the circumference of the base during the rotation of the turntable, thereby realizing multi-directional adjustment of the small shadowless lamp, and the small shadowless lamp is fixed by the cooperation of the first magnetic piece and the second magnetic piece, thereby improving the position stability of the small shadowless lamp, thereby expanding the overall applicability of the device, improving the irradiation effect of the shadowless lamp, and the adjustment is convenient and quick, which greatly improves the operating efficiency of the personnel.

[0039] The working principle is:

[0040] When in use, the small shadowless lamp is supported on one side of the shadowless lamp main body by the connecting arm, which can compensate for the un-irradiated position of the shadowless lamp main body. At the same time, multiple sliders are moved in the annular groove to establish a connection between the turntable and the base, and the turntable has a certain rotation range. The small shadowless lamp can be held by hand and rotated to a certain angle to change the irradiation angle and range of the small shadowless lamp. The position of the small shadowless lamp can be changed according to different body positions. At the same time, under the action of the first magnetic sheet and the second magnetic sheet, when the small shadowless lamp is in use, the slide plate can be pulled out and the first magnetic sheet and the second magnetic sheet can be separated. When the use of the small shadowless lamp is finished, the slide plate is returned to its position, and the small shadowless lamp is rotated in the opposite direction. The small shadowless lamp can be fixed by the adsorption of the first magnetic sheet and the second magnetic sheet, thereby giving a reset effect, which is convenient for the adjustment of the lighting auxiliary mechanism next time.

[0041] When the above-mentioned shadow-eliminating lighting mechanism is adopted, on the basis of reducing the blind area of ​​irradiation, the connecting arm drives the small shadowless lamp to move along the circumference of the base during the rotation of the turntable, thereby realizing multi-directional adjustment of the small shadowless lamp, and the small shadowless lamp is fixed by the cooperation of the first magnetic piece and the second magnetic piece, thereby improving the position stability of the small shadowless lamp, thereby expanding the overall applicability of the device, improving the irradiation effect of the shadowless lamp, and the adjustment is convenient and quick, which greatly improves the operating efficiency of the personnel.
