Stable 100W LED Illumination

High-CRI LED Array
100W high-CRI LED provides bright, natural white light for clear endoscopic visualization and accurate tissue color reproduction.

Constant-Current Drive
Constant-current control maintains stable LED output during continuous operation.

PWM Brightness Control
PWM control enables smooth and precise adjustment of illumination intensity.

Optical & Thermal Management

Optical Collimation
Built-in collimation concentrates LED output for efficient light transmission.

Fiber Coupling
The fiber-coupled design delivers a uniform illumination spot and helps reduce dark areas in the endoscopic field.

Copper-Tube Air Cooling
Pure copper-tube air cooling efficiently dissipates heat from the 100W LED for stable operation.

Flexible System Integration

Multiple Control Options
Brightness can be adjusted through buttons, potentiometers, or encoders.

Synchronized Control
The light source can synchronize with the main endoscopic camera system.

Touchscreen & Foot-Switch Control
Supports integration with touchscreen or foot-switch controls for convenient operation.

Integrated Status Monitoring

Dot-Matrix Display: Displays key operating information directly on the module.

Brightness Monitoring: Shows the current illumination level during operation.

Usage Time Tracking: Records accumulated operating time for usage monitoring and maintenance planning.

OEM Development Process

Requirement Review
Review the target equipment, optical output, electrical input, mounting space, fiber interface, and control requirements.

Sample Configuration
