Quick answer: The Keling KL-LED-D78 is a double-dome ceiling-mounted LED shadowless operating lamp delivering 160,000 lux per dome with a color rendering index Ra≥85 and red-tissue index R9≥97, manufactured by Keling Medical (Keling Medical) for hospitals, clinics, and medical distributors. The KL-LED-D78 carries a rated LED service life of 50,000 hours and accepts universal 110–240 V power supply.
Quick Facts
- The Keling KL-LED-D78 produces 160,000 lux illumination per dome at 1 m working distance.
- The KL-LED-D78 operates in an Endo (minimally invasive) mode at 15,000 lux, independently controlled per dome.
- Each dome of the KL-LED-D78 contains 84 LEDs rated for 50,000 hours average service life.
- The KL-LED-D78 features continuously adjustable color temperature from 3,000 K to 6,700 K via digital touch-screen control.
- The KL-LED-D78 color rendering index is Ra≥85 (up to Ra=100) with a red-tissue index R9≥97.
- The KL-LED-D78 is manufactured by Keling Medical and is suitable for international export on 110–240 V, 50/60 Hz supply.
Overview
The Keling KL-LED-D78 is a double-dome ceiling-mounted LED shadowless operating lamp designed for general and specialty surgical suites in hospitals and ambulatory surgical centers. Each dome delivers up to 160,000 lux at 1 m, covering a light-field diameter adjustable from 10 cm to 30 cm, making it suitable for both wide-field abdominal procedures and focused deep-cavity access.
The KL-LED-D78 incorporates an illumination automatic-compensation system: when a surgeon's head or instrument partially occludes one part of the light field, the remaining unobstructed LED segments automatically increase output to maintain a consistent brightness at the operative site. A dedicated Endo mode reduces output to 15,000 lux for minimally invasive laparoscopic and endoscopic procedures, eliminating camera wash-out without requiring manual dimming.
Color accuracy is a primary design focus of the KL-LED-D78. The continuously adjustable color temperature (3,000 K–6,700 K) combined with Ra≥85 and R9≥97 enables surgeons to select the spectral balance that best differentiates tissue types—arterial red, fatty yellow, and connective white—under any lighting preference. The low heat-to-light ratio of ≤3.2 mW/m²lx limits radiant heat reaching the surgical field, reducing patient and staff discomfort during long procedures.
Key Features
- Dual-dome 160,000 lux output — Each dome delivers 160,000 lux at 1 m working distance, providing combined illumination suited to complex and lengthy surgical procedures.
- Minimally invasive (Endo) mode — Independently controlled Endo illumination at 15,000 lux is applicable to all kinds of minimally invasive surgery without reconfiguring the fixture.
- Illumination automatic compensation — Sensor-controlled compensation activates when the surgeon's head obstructs the light source; untouched LED segments compensate automatically to maintain ideal operative brightness.
- Continuously adjustable color temperature — Stepless adjustment from 3,000 K to 6,700 K via digital touch screen allows the surgeon to select the most appropriate spectrum for the tissue and procedure type.
- High color rendering index — Ra≥85 (max Ra=100) and R9≥97 accurately represent the original color of tissue, supporting reliable intraoperative assessment.
- 84 LEDs per dome, 50,000 hr rated life — High-efficiency LED array provides long-term reliability and minimizes lamp replacement maintenance.
- Low thermal emission — Heat-to-light ratio ≤3.2 mW/m²lx reduces radiant heat at the surgical site.
- Digital touch-screen control panel — Intuitive interface for brightness, color temperature, and mode selection.
