Stryker Cold Light Source X8000 Maintenance Cases and Introduction

Product Introduction

The Stryker Cold Light Source X8000 is a high-end medical cold light device launched by Stryker Corporation, primarily used for surgical lighting, especially in endoscopic surgery systems. It employs xenon lamp technology, offering high brightness, low thermal radiation, and stable output, providing precise and uniform illumination for surgeries.

Key Features

High-Brightness Xenon Lamp: Equipped with a 300W xenon lamp, featuring a color temperature close to natural light and excellent color rendering, suitable for prolonged surgical procedures.

Intelligent Control System: Built-in microprocessor for real-time monitoring of bulb lifespan, power status, etc., with brightness adjustable via the panel or remote interface.

Multi-Layer Protection: Includes overvoltage, overcurrent, and overheating protection, with error codes (e.g., E1) indicating fault types for quick diagnosis.

Modular Design: Independent repairable components such as power supply, optical path, and control panel, reducing maintenance costs.

Typical Applications

Laparoscopic and arthroscopic minimally invasive surgeries.

Endoscopic examinations in ENT and urology.

Compatible with Stryker HD camera systems.

Technical Parameters (Example)

Light Source Type: Xenon lamp (300W).

Luminous Flux: ≥20,000 lumens.

Lifespan: Approximately 500-1000 hours (bulb).

Input Voltage: AC 100-240V, 50/60Hz.

Interface: Standard fiber optic interface (e.g., LG series).

Maintenance Tips

Regularly inspect bulb aging and reflector cleanliness.

Avoid frequent power cycling to extend bulb lifespan.

Promptly troubleshoot error codes (e.g., E1/E13) related to power or optical path issues.

(Note: Some parameters may vary by version; refer to the official manual for details.)

Maintenance Case

Visual Inspection

The host unit appeared intact externally, with no signs of physical damage, cracks, or deformities. The mounting bracket was secure.

Fault Symptoms

After connecting to AC power, internal arcing was observed, accompanied by error code E1 and dim light output. Further testing revealed sluggish response from the power button, indicating aging and malfunction.

Disassembly Diagnosis

Bulb Condition: Severe aging of the xenon lamp, with oxidized filaments and dust accumulation on the reflector, leading to reduced efficiency and arcing risks.

Circuit Testing: Abnormal voltage fluctuations in the power module, potentially linked to arcing.

Panel Inspection: Oxidized and worn-out power button contacts, requiring replacement of the panel component.

Repair Plan

① Replace Panel: Remove the old button module and install a new panel, testing touch sensitivity.

② Replace Bulb: Use an original 300W xenon lamp, ensuring proper installation (reflector orientation and avoiding surface contact) and cleaning the lamp socket.

③ Circuit Calibration: Repair abnormal circuits in the power module, replace damaged components, calibrate output voltage to standard range, and reinforce internal firmware and connections.

Repair Outcome

Post-repair, the host unit booted normally, error code E1 was resolved, light output brightness was restored, and panel functionality was fully recovered.
