  • Introduction

1. Extra-long service life:

A novel LED cold light source is used to extend the service life to up to 60,000 hours with no need to change beads. It’s superior to traditional halogen lamps and can meet the requirements of energy saving and environmental protection.

2. Perfect cold light effect

The spectrum of the novel LED cold light source used contains no ultraviolet or infrared lights, which brings neither heat nor radiation, and the temperature rises at the physician’s head and the surgical wound area ≤1℃, with almost no temperature rises.

3. Ideal appearance design in line with purification requirements:

The fully enclosed and streamlined lamp head design conforms to the design principle of aerodynamics, which thoroughly eliminates the dead corners of the flow in the purified air and meets the high-standard laminar requirements in modern operation rooms and is conducive to the aseptic requirements in operating rooms;

4. Humanized interface design:

The lighting brightness can be changed according to the hospital's need for different surgical lighting. Optional novel LED touch-screen LCD control panel is available for the turn-on/off and adjustment of illuminance, color temperature and brightness.

5. Ultra-strong deep lighting, perfect non-shadow effect:

The integral design of LED lamp head makes the light beams converge into a high-brightness uniform light column to ensure a soft and even deep beam-converging effect and the lighting need for high brightness and depth.

6. Color temperature adjustment function:

The color temperature of the Model CHGLED700/500 surgical shadowless lamp can be adjusted from 3500K to 5000K in six levels, which makes the diagnosis more accurate and will not cause eye fatigue of the medical staff due to long hours of work.

7. Good hanging system:

Lightweight high-quality suspension system with balance arm; six sets of universal joints are linked to enable light and 360° all-direction movement with accurate positioning to meet the needs of different heights, angles and positions during surgery.

8. Exquisitely structured focusing system:

The manual focusing technology enables simple and convenient operations and solves the technical difficulties in focusing of LED surgical shadowless lamps to realize non-grade focusing; detachable handle; can be sterilized at a high temperature (≤160°C); unique one-key mode for endoscope.

9. Bright and uniform lighting:

The light beams emitted by the LED light source go through a specially-designed high-performance lens and then converge on the surgical area to form a light field which meets the need of surgical lighting; the max. illuminance is up to 160,000 LUX. The brightness of the LED is adjusted in a non-grade digital way and the illuminance of each lamp can be adjusted separately.

10. Extremely low fault rate:

Each LED module contains 6-10 LED beads. Since each module has an independent electronic control system, the fault rate of the lamp head is very low and the fault of a single LED won’t affect the functions of the lamp head.

11. Low heat generation:

The greater advantage of LED is that it produces less heat, because it hardly emits infrared or ultraviolet rays.

12. Internal Camera System

The advanced camera systems from the manufacturer of professional camera systems, Hikvision (systems from other brands also can be used according to client needs) are adopted to ensure the functionality and practicability of the device. The camera is installed at the disinfection handle of the primary or secondary lamp head, the angle is adjustable and the angle is adjustable without dead ends.
