When the LED is applied to the operating lamp, light spots formed by the operating lamp are mainly formed by a plurality of LEDs of the operating lamp emitting light through the lenses to irradiate and gather on an irradiated surface, namely, the energy illumination of the light spots is formed by superposing the energy illumination of the light emitted by each lens. However, the LEDs of the above-described surgical lamp have almost the same relative illuminance through each lens, and the illuminance is not uniform and the distribution is poor.

In order to achieve the purpose, the technical scheme of the invention is as follows:
the surgical lighting system comprises at least two light source groups and is characterized in that each light source group is provided with a lens and a light emitting piece, light emitted by the light emitting piece forms light spots on an object through the lens, the light emitted by the light emitting piece of each light source group generates illumination through the lens, and the light spots formed by the two light source groups are superposed at the same position of the object.
Preferably, the relative illuminance distribution state generated by the light emitted by one of the light-emitting members through the lens is higher within the range of smaller spot diameter, and is lower when the spot diameter is larger.
Preferably, the relative illuminance distribution state generated by the light emitted by one of the light emitting elements through the lens is lower within a range of smaller spot diameter, the illuminance is higher when the spot diameter is within a predetermined range, and the illuminance is further reduced when the spot diameter exceeds the predetermined range.
Preferably, the light emitted by the light emitting elements of all the light source sets generates light spots with different illumination intensities through the lens to irradiate and overlap at the same position, and when the diameter of the light spot is within a specific range, the illumination intensity is approximately kept constant.
Compared with the prior art, the invention has the beneficial effects that:
the illumination and distribution are more balanced, and the optical performance is better.

Detailed Description
While the present invention is described in detail with reference to the preferred embodiments and the drawings, it is understood by those skilled in the art that the present invention can be applied to various forms of surgical lighting fixtures, and the description terms of the present invention include the above description without limiting the application field, for example, the material or shape terms include and are not limited to the material or shape specified in the description, and the position terms include and are not limited to the arrangement, proximity, connection, or adjacency. The term "a" or "an" includes one and more than one of a plurality of elements. In the present specification, directional terms such as "upper", "lower", "inner", "outer", "top" and "bottom" are used only as exemplary terms with reference to a normal use direction, and are not intended to limit the scope of claims.
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
In the preferred embodiment, as shown in fig. 1, the surgical illumination system includes at least two light source groups 10, each of the two light source groups 10 has a lens 12 and a light emitting element 11, the light emitting element 11 of each of the two light source groups 10 is located at a position corresponding to the incident surface of the lens 12, and optionally, there may be no medium between the light emitting element 11 and the lens 12 or an optical film for enhancing the light effect. The light emitting element 11 is a Light Emitting Diode (LED), and light emitted from the light emitting element 11 can form light spots towards an object or an illumination area through the lens 12, and the light spots formed by all the light source sets 10 are illuminated and superposed at the same position.
As shown in fig. 2, the light emitted from the light emitting element 11 of each of the two light source groups 10 generates different illumination intensities through the lens 12, and optionally, a relative illumination intensity distribution state of the light emitted from the light emitting element 11 of one of the light source groups 10 through the lens 12 is shown as a curve a, where the curve a shows that the illumination intensity is higher in a range with a smaller spot diameter, and the illumination intensity is lower in a range with a larger spot diameter. The light emitted from the light emitting element 11 of the other light source group 10 is distributed as a curve B according to the relative illuminance generated by the lens 12, the curve B shows that the illuminance is rather low within the range of the smaller spot diameter, the illuminance is higher when the spot diameter is within a predetermined range, and the illuminance is further reduced when the spot diameter exceeds the predetermined range.
As shown in fig. 3, since the light emitted from the light emitting elements 11 of different light source groups 10 generates different illumination intensity light spots through the lens 12 and the light spots are superposed on the same position, the illumination intensity of the curve C represents the superposed illumination intensity distribution state, and when the diameter of the light spot is within the specific range D, the illumination intensity is generally maintained at a constant value, so that the illumination shows a more uniform and balanced distribution state.
The embodiments described above are only a part of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
