Product Overview
This LED surgical light is specifically engineered to meet the demands of all surgical specialties, delivering high illuminance, uniform light distribution, shadow-free performance, and minimal thermal radiation-ensuring a clear surgical field without tissue desiccation.
Optical Performance Specifications
Central illuminance: ≥ 140,000 lux at 1 m distance
Illuminance adjustment: Continuously variable from 1% to 100% (stepless dimming)
Light field diameter: Adjustable from 13 to 33 cm to accommodate different surgical sites
Illumination depth: ≥ 130 cm, providing ample brightness for deep cavity procedures
Uniformity and shadow elimination: Highly homogeneous light field with complete shadow-free illumination
Color temperature options: Three preset values (3800±500K, 4400±500K, 5000±500K) selectable via LCD panel; total adjustable range from 3000K to 5700K
Color rendering index: CRI ≥ 97, R9 (red rendering index) ≥ 93, Ra > 96, ensuring true tissue color fidelity
Light Source and Thermal Management
Light source type: High-performance medical‑grade LEDs from OSRAM
Heat emission: Extremely low thermal output, equipped with overheat protection to prevent tissue drying in the operative field
LED rated life: ≥ 100,000 hours, offering long‑term maintenance‑free operation
Power consumption: ≤ 100 W, energy‑efficient design
Power Supply and Emergency Backup
Input voltage: AC 110–240 V, 50/60 Hz, compatible with worldwide standards
Built‑in backup battery: Provides ≥ 3 hours of continuous operation in case of power failure
Ergonomics and Mobility
Multi‑joint articulated arm: Allows 360° rotation for flexible and stable positioning
Precise locking: Adjustable joint friction ensures reliable retention at any desired angle
Central handle: Autoclavable for sterile intraoperative manipulation
Beam size adjustment: Manual control for varying light field diameter
Control interfaces: Optional wall‑mounted controller or touch panel to suit operating room layout preferences

Main features
- The independent heat dissipation system and independent opticalunitare convenient for later maintenance
- Independent maintenance can be realized without disassembling other irrelevant units during maintenance.
- Ultra-thin hollow-shaped lamp head, good laminar flow penetration effect.
- Manually adjust the spot to meet the needs of the size of the spot irradiation area.
- The constant current drive design is adopted to keep the working current in a stable state forever, greatly prolonging the service life.
- With the Osram light beads, ensure a long lifespan of over 100,000 hours, delivering enduring performance.
Introduction
1. Fully hygienic:Striking sleek lines without cutting edges. Rounded curves and smooth surfaces for quick and easy cleaning. Shock resistant coating.
2. Minimal laminar-flow interference.----------the fully sealed light head has been aerodynamically designed to minimize turbulence of laminar-flow.
3. environmental clean---We have taken the technology and developed it further to provide high definition lighting solutions with no infrared, low environmental impact, high brightness, low power consumption, no toxic chemicals and a long operating life.
4. 3,300 ~ 5,700K (± 500) variable colour temperature
5. Manual focus
