Open the top cover if the surgical light is not lit, check whether the fuse is blown and whether the power supply voltage is normal. Assuming there is no problem with both, ask a professional to patch it. There are generally two causes of transformer damage, namely power supply voltage problems and overcurrent caused by short circuits, the latter should be repaired by professionals sent by the surgical lamp manufacturer.

If fuses are often damaged, and it is necessary to check that the shadowless lamp is equipped according to the power rating rules in the manual. Assuming that an overpowered bulb is equipped, the fuse will be damaged due to the capacity exceeding the fuse rated current. Check whether the power supply voltage is normal, the disinfection of the shadowless lamp handle can be carried out by high-pressure disinfection, but pay attention to the handle which can not be pressed by heavy objects during disinfection, otherwise the handle will be deformed.

Turn the shadowless lamp to a viewpoint, the light will not light up, mainly because the sensors at both ends of the shadowless lamp boom will be in poor contact after a period of use, which should be maintained by professionals. In large-scale surgical shadowless lamps, after a period of use, because the weight of the inner lamp cap is heavy, the friction required is required to position it, which will lead to movement. It can be handled by increasing friction by tightening the upper registration screw.

The brightness of the surgical shadowless lamp is dimmed, and the reflective glass bowl of the shadowless lamp adopts coating technology. After years of use, the coating may experience problems such as darkening of reflections and blistering. If this happens, change the reflector.
