1. Inspection of the mechanical installation of the surgical shadowless lamp: Check whether there are any mechanical installation defects, whether there are missing screws or not tight screws. Whether the circlips are properly clamped, and whether the decorative covers have been covered.

2. Circuit inspection: First, check whether the system has a short circuit or open circuit. If everything is normal, you can perform a power-on test. At this time, check whether the external power supply of the shadowless lamp is stable. Whether the output voltage of the transformer is too high or too low.

3. Balance arm adjustment: Check whether the balance arm matches the lamp holder, whether it is necessary to adjust the force of the balance arm, whether it is necessary to adjust the angle of the balance arm and the need can be adjusted through the adjustment method of the lamp arm. Usually the screws for adjusting the lamp arm are at the two ends of the lamp arm, but it is slightly different for different manufacturers, so you can observe carefully.

Fourth, joint flexibility adjustment: mainly to adjust the damping screw of the joint. The standard stipulates that the tightness of the damping adjustment is that the force of pushing or rotating the joint at any position is close to 20N or 5Nm.

5. Adjustment and release of the joint limit switch: In order to facilitate the installation and transportation of the shadowless lamp, most of the shadowless lamp products are equipped with a lock switch or limit switch in their key parts such as joints. They can be opened now.

6. ​​Check the irradiation distance and depth: The irradiation distance of most shadowless lamps is 70-140cm or 60-130cm. That is to say, the effect of shadowless lamps is the best in this distance.

Seven, check the illuminance and color temperature: Illumination and color temperature are actually an approximate concept. Both are to describe the intensity of the shadowless lamp. Usually we think that the most ideal shadowless lamp is that the light is similar to the sunlight, that is, around 4400-4600K.
