FY-4+5A Ceiling-mounted LED Surgical Light

Overview
Ceiling-mounted dual-head surgical light featuring ultra-thin five-petal lamp heads for main and auxiliary illumination. Adjustable color temperature 3700–5000K, central illuminance up to 160,000 Lux and effective working depth over 1200 mm. Designed for operating rooms requiring precise color rendering and stable shadow management.

Key Features

• Premium cold light source: Imported OSRAM LED chips with service life ≥80,000 hours. Operator head temperature rise <1℃. No infrared or ultraviolet emission; stable color temperature with low light decay. Built-in R9 red and R11 green spectrum for improved tissue color rendering and reduced visual fatigue.
• Excellent shadowless performance: Ultra-thin five-petal lamp head with modular multi-point light source provides uniform illuminance and flexible spot adjustment, maintaining shadowless effect under partial obstruction. Diamond-cut lens structure reduces light loss and disperses direct glare for comfortable illumination.
• Outstanding deep illumination: Modular optical design delivers lighting depth >1200 mm and maximum central illuminance up to 160,000 Lux. Adjustable spot diameter and color temperature for accurate tissue visualization.
• Intelligent digital control system: Microcomputer control with LCD touch screen for stepless brightness and color temperature adjustment. Multiple modes: general lighting, endoscopic mode and dim light mode. Built-in memory saves custom settings. Independent multi-circuit design prevents single LED failure from affecting full lamp operation.
• Flexible universal suspension system: Rotary arm in high-performance alloy with imported balance spring components. Lightweight, smooth operation and precise positioning with wide adjustment range. Fatigue correction and fine-tuning device for easy calibration.
• Laminar flow optimized lamp head: Ultra-thin five-petal head (maximum thickness ≤9 cm) to maintain laminar airflow. Each petal includes integrated handle; detachable central handle withstands 134℃ high-pressure autoclave sterilization. Housing made of ABS.
• Optional functions: Mutual control between lamp heads and automatic shadow compensation.
