## Overview

The Keling KL-LED-DTR78 is a double-dome ceiling-mounted LED shadowless operating lamp with integrated camera system, designed for hospitals and surgical centers requiring high-performance illumination combined with intraoperative video documentation. Each primary dome delivers 160,000 lux at 1 m using OSRAM LED components. The titanium-alloy balance arm ensures stable, drift-free positioning throughout lengthy procedures — a critical feature in high-precision surgery where lamp movement between adjustments must be eliminated.

The KL-LED-DTR78 incorporates a computer-programmed optical arrangement for high shadowless rate, and high thermal conductivity heat dissipation technology to maintain a low temperature rise within the fixture and at the operative site. Optical PC lenses on each LED element provide anti-glare performance for the surgical team. The heat-to-light ratio is ≤3.2 mW/m²lx, limiting radiant heat exposure during long procedures.

The KL-LED-DTR78 offers a comprehensive set of illumination modes: an Endo mode at 15,000 lux for minimally invasive procedures, a green light mode (R11≥97) specifically engineered for cardiac and neurosurgery disciplines requiring high green color rendering, and continuously adjustable color temperature from 3,000 K to 6,700 K. Illumination automatic compensation activates when occlusion is detected, maintaining consistent brightness at the operative field. The RI index function is specifically designed for high color-rendering tasks including deep and difficult incisions where tissue color discrimination is most critical.

## Key Features

- **OSRAM LED components** — Double-dome configuration uses OSRAM LEDs for reliable, high-fidelity output: 84 LEDs in dome 1, 144 LEDs in dome 2.
- **Titanium-alloy balance arm, no-drift** — Titanium-alloy arm maintains stable lamp position without drift during procedures, eliminating the need for repeated repositioning.
- **Integrated camera system** — Built-in camera supports intraoperative video documentation, recording, and telemedicine or remote-viewing applications.
- **Green light mode (R11≥97)** — Dedicated mode for cardiac surgery and neurosurgery requiring precise color rendering of vascular and neural tissue.
- **RI index function** — Specially designed for high color-rendering tasks including deep and difficult incisions, with independently controlled illumination to show color differences and fine tissue detail.
- **Minimally invasive (Endo) mode** — Independently controlled Endo illumination at 15,000 lux, electrically adjusted, applicable to all kinds of minimally invasive surgery.
- **Illumination automatic compensation** — Automatically compensates when doctor's head covers the light source, maintaining ideal operative brightness from unobstructed LED segments.
- **Computer-programmed optical arrangement** — High shadowless rate achieved through optimized LED geometry.
- **Anti-glare optical PC lens** — PC lenses on each LED element reduce glare and improve team visual comfort.
- **High thermal conductivity heat dissipation** — Low temperature rise technology protects LED life and limits heat-to-light ratio to ≤3.2 mW/m²lx.
