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.

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 Jiangsu Keling Medical Appliances Co., Ltd. and is suitable for international export on 110–240 V, 50/60 Hz supply.

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.
