performance specification ：
1. Exceptional cold light performance with extended lifespan:
The novel LED cold light source is adopted, which emits soft light without
ultraviolet (UV) or infrared (IR) radiation in its spectrum, generating neither heat nor
radiation. The temperature rise in the physician’s head and wound areas is ≤1°C, with virtually no thermal increase. The LED light beads have a lifespan exceeding
60,000 hours, meeting the requirements for energy conservation and environmental
protection. 2、Excellent optical parameters; multi-level adjustable illumination and color
temperature functions;
The illumination and color temperature are adjustable in multiple levels
(1-100), allowing customization to the optimal brightness and color temperature for
surgical procedures. This ensures the required brightness for surgery while effectively
alleviating the surgeon’s visual fatigue. The novel LED cold light source with high color rendering index enhances
Shandong Mingxu Medical Equipment Co.,Ltd. the color contrast between blood and other human tissues and organs. During
venipuncture, the color variation of illumination enables physicians to better visualize
venous tissues. The integrated design of the LED lamp head focuses the light beam into a
high-brightness uniform beam, ensuring a soft and uniform deep focus effect to meet
the surgical requirements for high-brightness and high-depth illumination. 3. Advanced control systems:
Equipped with LCD display and button control, it enables the power switch for
illumination as well as the adjustment of illuminance and color temperature modes. Additionally, it features one-touch endoscope mode and real-time LCD display of
illuminance and color temperature values, meeting the hospital’s demand for rapid
switching between different surgical lighting modes. Digital memory function automatically remembers the appropriate lighting level, so you don’t need to adjust it when you turn it on again
Multiple centralized control methods with identical power for multiple channels
and groups ensure that abnormalities in a single channel or individual LED do not
affect surgical illumination. 4. Form factor compliant with purification requirements:
The lamp head design adopts a petal shape to significantly reduce turbulence. The
streamlined lampshade of the entire arm is meticulously designed based on
aerodynamic principles, fully complying with the standards of modern
new-generation operating rooms. 31
Shandong Mingxu Medical Equipment Co.,Ltd. All lamp heads are secured with silicone sealing strips, ensuring an aesthetically
smooth appearance, easy cleaning, and resistance to dust accumulation and fluid
ingress. This design meets the high standards of laminar flow required in modern
operating rooms, thereby facilitating the aseptic conditions necessary for surgical
procedures. 5. A well-designed suspension system:
The curved double-bend pipe structure, designed to match the lamp head’s shape, ensures both a stable center of gravity and smooth rotation. The long-cone rotating arm assembly features a stacked configuration with the large
arm (900mm) and small arm (750mm) of varying lengths, each independently
rotating, and is connected by a high-sensitivity carbon brush. The balance arm incorporates an alloy material and high-toughness spring, ensuring smooth movement and effortless positioning, with a range of 90-degree
vertical span and 340-degree horizontal rotation. (50,000 cycles fatigue test)
Comprehensive design with six sets of universal joints interconnected, each joint
featuring a bearing structure and utilizing elastic damping screws. A single
adjustment ensures long-term usability, meeting various height, angle, and
positioning requirements during surgery. The system offers convenient mobility and
precise positioning. 6. A compact and sophisticated focusing system:
The device features simple and convenient operation with stepless focusing
capability. The detachable sterile handle is manufactured from heat-resistant

engineering plastic (PPSU) and can withstand high-temperature sterilization (≤160° C). 7. The lampshade is made of optical-grade acrylic, featuring wear resistance,
easy cleaning, and high light transmittance. 8. Components from well-known brands
The power supply switch uses the Taiwan brand Mingwei, and the plastic
powder employs the Swiss-imported Akesu brand. This plastic powder has passed the
EU ROHS certification, featuring antibacterial and fire-resistant properties. It not
only prevents turbulence formation but also facilitates nurse disinfection and cleaning, while meeting the requirements of hospital infection control and safety. 9. Multiple configuration options
Supports configurable configurations including six-petal, five-petal, three-petal, pendant, vertical, and wall-mounted styles
The system can be equipped with additional functions such as synchronization
control system, high-definition digital camera system and 360° balance arm.
