1. The main light is off, but the secondary light is on

There is an automatic switching function in the circuit control of the shadowless lamp. When the main lamp is damaged, the auxiliary lamp will be on to ensure the normal operation of the operation. When the operation is over, the main lamp bulb should be changed immediately.

2. The light does not light up

Open the top cover of the shadowless lamp, check whether the fuse is blown, and whether the power supply voltage is normal. If there is no problem with both, please ask a professional to repair it.

3. Transformer damage

Generally, there are two reasons for transformer damage. Power supply voltage problems and circuit short-circuits cause large current to cause transformer damage. The latter should be repaired by professionals.

4. The fuse is often damaged

Check whether the bulb in use is configured according to the rated power specified in the manual. A bulb with too large power will cause the capacity of the fuse to exceed the rated current and cause the fuse to be damaged. Check whether the power supply voltage is normal.

5. Deformation of the disinfection handle

The handle of the shadowless lamp can be sterilized by high pressure (please refer to the instruction manual for details), but please note that the handle cannot be pressed during disinfection, otherwise it will cause the handle to deform.

6. When the shadowless lamp rotates, the lamp does not turn on

This is mainly because the sensors at both ends of the shadowless lamp boom will have poor contact after a period of use. In this case, you should ask a professional for maintenance.
7. The brightness of the hole lamp becomes dim

The reflective glass bowl of the cold light hole shadowless lamp adopts coating technology. Generally, the domestic coating technology can only guarantee a two-year life. After two years, the coating layer will have problems, such as dark reflections and blistering. Therefore, in this case, the reflector needs to be replaced.

8. Emergency lights

Customers using emergency lights, regardless of whether they are used or not, must ensure that the battery is charged once within 3 months, otherwise the battery will be damaged.
