在内窥镜检查与微创手术中，光源如同 “黑暗中的火炬”，为医生的精准操作提供清晰视野。一旦光源出现故障，检查与手术进程都会受到影响。想要让内窥镜光源 “重见光明”，需要对故障原因抽丝剥茧，并掌握科学的修复方法，才能让其恢复往日的明亮。

　　In endoscopic examination and minimally invasive surgery, the light source is like a "torch in the dark", providing a clear view for the doctor's precise operation. Once the light source malfunctions, both the inspection and surgical process will be affected. To restore the brightness of the endoscope light source, it is necessary to thoroughly investigate the cause of the malfunction and master scientific repair methods in order to restore its former brightness.

　　诊断故障：找准光源 “症结”

　　Diagnosing faults: Identifying the root cause of the light source

　　修复光源的第一步是准确判断故障原因。常见的光源问题包括亮度不足、闪烁、完全不亮等。若光源亮度逐渐减弱，可能是灯泡老化导致。随着使用时间增加，灯泡的灯丝会逐渐损耗，发光效率下降。而光源闪烁，大概率是电路接触不良引起，比如电源线松动、接头氧化，或是电路板上的焊点虚焊。要是光源完全不亮，除了灯泡烧毁，还可能是电源供应系统故障，像变压器损坏、保险丝熔断，亦或是控制光源的驱动电路出现问题。通过细致观察光源表现，结合专业工具检测，如使用万用表测量电路通断与电压，才能精准定位故障点。

　　The first step in repairing a light source is to accurately determine the cause of the malfunction. Common light source issues include insufficient brightness, flickering, and complete lack of illumination. If the brightness of the light source gradually decreases, it may be caused by the aging of the light bulb. As the usage time increases, the filament of the light bulb will gradually wear out and the luminous efficiency will decrease. And the flickering of the light source is most likely caused by poor circuit contact, such as loose power lines, oxidized connectors, or virtual soldering of solder joints on the circuit board. If the light source does not light up at all, besides the bulb burning out, it may also be a fault in the power supply system, such as a damaged transformer, blown fuse, or a problem with the driving circuit that controls the light source. By carefully observing the performance of the light source and combining it with professional tools for detection, such as using a multimeter to measure circuit continuity and voltage, the fault point can be accurately located.

　　灯泡更换：为光源注入 “新活力”

　　Light bulb replacement: injecting "new vitality" into the light source

　　当确定是灯泡故障时，更换灯泡是直接有效的解决办法。更换前，务必先关闭光源设备并断开电源，等待灯泡冷却，避免烫伤。不同类型的内窥镜光源，灯泡规格与安装方式有所差异。一些光源的灯泡安装在独立的灯座内，需拧下固定螺丝，小心拔出旧灯泡，注意不要触碰灯泡玻璃表面，因为手上的油脂会影响灯泡寿命和发光效果。安装新灯泡时，将其准确插入灯座，确保接触良好，再拧紧螺丝固定。更换后，接通电源测试，若光源恢复正常亮度且无闪烁，说明更换成功。

　　When it is determined that it is a bulb malfunction, replacing the bulb is a direct and effective solution. Before replacing, be sure to turn off the light source device and disconnect the power supply, wait for the light bulb to cool down, and avoid burns. Different types of endoscopic light sources have differences in bulb specifications and installation methods. Some light source bulbs are installed in separate lamp sockets, and the fixing screws need to be unscrewed. Carefully remove the old bulb and be careful not to touch the glass surface of the bulb, as the grease on your hands can affect the lifespan and luminous effect of the bulb. When installing a new light bulb, insert it accurately into the lamp holder to ensure good contact, and then tighten the screws to secure it. After replacement, turn on the power for testing. If the light source returns to normal brightness without flickering, it indicates successful replacement.

　　电路检修：疏通光源的 “电力脉络”

　　Circuit maintenance: unclogging the "power network" of the light source

　　针对电路问题，需要逐步排查检修。先检查电源线和接头，查看是否有破损、断裂，若发现外皮破损，可使用绝缘胶带包扎；对于氧化的接头，用砂纸轻轻打磨，去除氧化层，恢复良好的导电性能。若问题出在电路板，需借助放大镜仔细观察焊点，寻找虚焊、脱焊的部位。使用电烙铁对虚焊点进行补焊，操作时要控制好温度和焊接时间，避免烫坏电路板。对于损坏的电子元件，如电容、电阻等，要准确识别其规格型号，更换上新的元件。在整个电路检修过程中，每完成一步操作都要进行通电测试，确保故障逐步排除。

　　For circuit issues, it is necessary to gradually troubleshoot and repair them. First, check the power cord and connectors for any damage or breakage. If the outer skin is found to be damaged, it can be wrapped with insulating tape; For oxidized joints, gently sand them with sandpaper to remove the oxide layer and restore good conductivity. If the problem lies on the circuit board, it is necessary to carefully observe the solder joints with a magnifying glass and search for areas of virtual soldering or detachment. Use an electric soldering iron to repair solder joints, and control the temperature and soldering time during the operation to avoid damaging the circuit board. For damaged electronic components such as capacitors, resistors, etc., it is necessary to accurately identify their specifications and replace them with new components. During the entire circuit maintenance process, a power on test must be conducted for each completed step to ensure that the fault is gradually eliminated.

　　电源系统维护：稳固光源的 “能量根基”

　　Power system maintenance: stabilizing the "energy foundation" of the light source

　　电源供应系统是光源稳定工作的基础。若变压器出现故障，比如绕组短路、断路，通常需要专业人员进行维修或更换。保险丝熔断时，要查明熔断原因，排除电路过载或短路故障后，再更换相同规格的保险丝。此外，定期对电源系统进行清洁保养，清除灰尘和杂物，防止因积尘导致电路短路。检查电源模块的散热风扇是否正常运转，若风扇停转或转速异常，会影响电源模块的散热，进而导致性能下降甚至损坏，需及时修复或更换风扇。

　　The power supply system is the foundation for stable operation of the light source. If a transformer malfunctions, such as winding short circuit or open circuit, it usually requires professional personnel to repair or replace it. When a fuse blows, it is necessary to identify the cause of the blow, eliminate circuit overload or short circuit faults, and then replace the fuse with the same specification. In addition, regularly clean and maintain the power system, remove dust and debris, and prevent circuit short circuits caused by dust accumulation. Check if the cooling fan of the power module is running normally. If the fan stops running or has abnormal speed, it will affect the cooling of the power module, leading to performance degradation or even damage. It is necessary to repair or replace the fan in a timely manner.

　　专业校准：让光源 “精准发力”

　　Professional calibration: enabling the light source to exert precise power

　　修复后的光源，还需进行专业校准，确保其发光强度、色温等参数符合标准。使用专业的光学检测设备，对光源的各项指标进行测量，根据测量结果调整光源的相关设置。例如，通过调节光源的调光旋钮或控制软件，将亮度调整到合适范围，使色温达到内窥镜检查所需的标准，保证成像清晰、色彩还原准确。

　　The repaired light source needs to undergo professional calibration to ensure that its luminous intensity, color temperature, and other parameters meet the standards. Use professional optical detection equipment to measure various indicators of the light source, and adjust the relevant settings of the light source based on the measurement results. For example, by adjusting the dimming knob or control software of the light source, the brightness can be adjusted to a suitable range to achieve the color temperature required for endoscopic examination, ensuring clear imaging and accurate color reproduction.

　　内窥镜光源的修复是一项需要耐心与专业技能的工作。从故障诊断到具体修复，再到最后的校准，每一个环节都至关重要。掌握这些修复方法，能够及时解决光源故障，保障内窥镜设备的正常使用，为医疗诊断和手术操作提供可靠的照明支持。

　　The repair of endoscopic light sources requires patience and professional skills. From fault diagnosis to specific repair, and finally calibration, every step is crucial. Mastering these repair methods can promptly solve light source failures, ensure the normal use of endoscopic equipment, and provide reliable lighting support for medical diagnosis and surgical operations.
