A light beam emitted by the second lighting unit forms a second light spot having a second equivalent diameter in the operating field, and the second light spot have a light distribution that does not meet the operating lamp standard. The second equivalent diameter is greater than the first equivalent diameter. The control unit is configured to control working states of the first lighting unit and the second lighting unit, and enable the operating lamp to provide the first light spot or a synthetic light spot having a light distribution that meets the operating lamp standard and is formed by the first light spot and the second light spot.
