Problems solved by technology
Although this solution has a simple lamp head structure and high reliability, when it is adjusted to a large spot, the peripheral area of the large spot on the lighting surface is only formed by individual lighting units. The doctor's head is covered, and the lighting spot may be partially darkened
[0006] Another solution is to add optical elements to the operating light and use the movement of specific optical elements to adjust the size of the illumination spot. Although the adjustment reliability is good, the processing and installation of the optical elements are more difficult.

Embodiment Construction
[0028] Such as figure 1 As shown, the surgical light provided by an embodiment includes a lamp head 1 , a first lighting unit 2 and a second lighting unit 3 , and a control unit 20 . Both the first lighting unit 2 and the second lighting unit 3 are installed on the lamp holder 1 . The control unit 20 is used to control the working state of the first lighting unit 2 and the second lighting unit 3 , for example, it can control the first lighting unit 2 and the second lighting unit 3 to be in the lighting state or the extinguishing state. The control unit 20 can be set on the lamp head 1, or on other structures of the operating light, for example, on a light pole not shown in the figure. The control unit 20 can be connected with the first lighting unit 2 and the second lighting unit 3 through wired connection or wireless connection, so as to control the working status of the first lighting unit 2 and the second lighting unit 3 .
[0029] The lamp head 1 has an optical axis L0, ...

The invention provides an operating light and an operation field light spot adjustment method of the operating light. The operating light includes a first lighting unit (2), a second lighting unit (3) and a control unit. The light beam (4) emitted by the first lighting unit (2) forms a first light spot in the operation field area (6), and the first light spot has a light distribution that meets the operating light standard. The light beam (5) emitted by the second lighting unit (3) forms a second light spot in the surgical field area (6), the second light spot has a light distribution that does not meet the operating light standard, and the equivalent diameter of the second light spot is larger than that of the first light spot equivalent diameter. The control unit is used to control the working state of the first and second lighting units, and can make the operating light provide the first light spot or the synthetic light spot formed by the first and second light spots with the light distribution conforming to the standard of the operating light.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an operating lamp and a method for adjusting light spots in an operating field. Background technique [0002] Existing surgical lamps generally have multiple lighting units on the lamp head. These lighting units are placed on the lamp head at different angles to provide light beams that all point to the operation area but have different exit angles. These light beams form an illumination spot in the operation area. [0003] In the clinic, different surgical types have surgical fields of different sizes. The size of the illumination spot in the operation area needs to be adjusted according to the size of the operation area. If the illumination spot is smaller than the operation area, part of the operation area is not fully illuminated, affecting the operation process. If the lighting spot is much larger than the surgical area, since the reflective rate of sterile drapes,...
