Product Overview
FY-3+4A ceiling-mounted combined petal LED surgical shadowless lamp with dual heads (3-petal + 4-petal). Uses imported OSRAM LEDs, diamond-cut optical lenses and an intelligent touch control system to provide high color fidelity, effective shadow elimination, deep cavity illumination and ultra-low heat generation. Designed for general surgery, orthopedics, gynecology, endoscopic procedures and medium-to-large operations in standard operating rooms.

Core Advantages / Key Features

• Cold light source — long life and low heat
  • Equipped with imported OSRAM LED beads; service life ≥ 80,000 hours.
  • Ultra-low temperature rise: operator head temperature rise <1℃, safe for prolonged procedures.
  • No infrared or ultraviolet radiation; reduces risk of tissue damage and avoids radiation pollution.
  • Stable color temperature and minimal light decay; soft light close to natural daylight; anti-glare for clinician comfort.
  • Built-in R9 (red) and R11 (green) spectrum enhancement for improved visualization of vessels and tissue details.
• Outstanding shadowless effect & optimized optics
  • Combined 3-petal + 4-petal heads with modular multi-point light sources for even illumination and flexible spot adjustment; maintains shadowless performance when partially occluded.
  • Diamond-cut optical lenses optimize refraction/reflection paths to reduce loss and improve light utilization; disperses direct light to minimize glare.
• Deep cavity illumination
  • Computer-aided modular optical focusing design with effective lighting depth of 50-180 cm; maximum central illuminance up to 160,000 Lux.
  • Adjustable color temperature 3700K-5000K to accurately restore tissue color during complex procedures.
• Intelligent human-centered control
  • Microcomputer digital control with LCD touch screen for easy brightness and color temperature adjustment.
  • Multiple modes: general, endoscopic and low-light modes for different surgical scenarios.
  • Automatic memory saves customized lighting parameters.
  • Independent multi-circuit design: single LED failure does not affect overall lamp operation.
• Sturdy suspension system and flexible positioning
  • High-performance balanced arm with imported spring components for smooth, lightweight movement and precise positioning.
  • Fatigue correction and fine positioning mechanism for easy recalibration after long-term use.
• Ultra-thin laminar-flow lamp head suitable for clean rooms
  • Streamlined petal design with maximum thickness ≤ 9 cm to preserve laminar airflow and meet OR hygiene requirements.
  • ABS lamp housing; integrated handle on each petal for convenient aseptic adjustment.
  • Detachable central handle resistant to 134℃ high-temperature, high-pressure sterilization to meet clinical disinfection standards.
