Overview
The Keling KL-LED-STR78 is a single-dome ceiling-mounted LED shadowless operating lamp intended for surgical suites requiring high-fidelity color rendering and versatile illumination control. With a peak output of 160,000 lux at 1 m, it covers demanding general and specialty surgical procedures from a compact single-dome ceiling configuration. Light field diameter is electrically adjustable from 10 cm to 30 cm, and a 4-position memory function stores preferred brightness and field-size settings for quick recall between procedures or surgeons.
The KL-LED-STR78 incorporates automatic illumination compensation: a sensor port detects occlusion when the surgeon's head obstructs the light source, triggering automatic output increase from the unobstructed LED segments to maintain consistent operative brightness. A titanium-alloy independent step array delivers depth illumination suitable for deep-cavity procedures, eliminating glare from medical staff without compromising the illuminated surgical field.
A key differentiating feature of the KL-LED-STR78 is its green light mode, engineered for procedures such as cardiac surgery and neurosurgery that require a high green color rendering index (R11≥97). Combined with the standard Ra≥85 and R9≥97 specifications, this mode supports surgeons working with fine vascular structures where tissue-color discrimination is critical. The hollow lamp body design promotes smooth laminar airflow around the fixture, supporting clean-room and laminar-flow OR environments.
Key Features
- 160,000 lux single-dome output — High-intensity illumination at 1 m working distance suitable for complex, long-duration surgical procedures.
- Automatic illumination compensation — Sensor port detects head occlusion; untouched LED segments compensate automatically to ensure ideal operative brightness.
- Green light mode (R11≥97) — Dedicated mode for cardiac surgery and neurosurgery requiring precise color rendering of vascular and neural tissue.
- Minimally invasive (Endo) mode — Independently controlled illumination at 15,000 lux applicable to all minimally invasive surgery types.
- Independent depth illumination — Titanium-alloy independent step array provides depth illumination for deep-cavity procedures while eliminating glare for surrounding staff.
- Electrically adjustable light field — Light field diameter adjustable from 10 cm to 30 cm with 4-position memory function for rapid recall.
- Adjustable color temperature — Continuously adjustable from 3,000 K to 6,700 K to match tissue type and surgeon preference.
- Hollow lamp body for laminar flow — The hollow lamp body design follows smooth laminar surface principles, providing excellent laminar flow cleaning adaptability in sterile OR environments.
- High color rendering index — Ra≥85 (max Ra=100) and R9≥97 accurately represent original tissue color; RI index function benefits deep and difficult incisions.
