5 Revolutions of Shadow-less Operation Light
The Mid 19th Century
Form The Prototype of Shadowless light
People install mirrors in the 4 corners of the operating room ceiling and use the mirror to reflect sunlight to increase the light on the operating table.
The 1920s
Early Shadowless Light
Medical scientist Welland unifornly placed many narrow flat nirrors on the dome, and an 100 watt lamp was placed in the center of the dioptric lens.
From the 1980s and 1940s to the 1950s
Revolution and Development
The 1980s-1940s: Single Lamp Type Shadowless light from France; Track Lamp from USA but illuminance was stil very low.
The 1950s: Hole Type Multi-lamp Shadowless Lamp produced in Europe and Japan but the heat remperature difficult to be contolled.
From the 1980s to the early 2lst Century
Technical Improvement
The 1980s: Halogen light source operating lamp, better control the temperature rising.
The 1990s:Integral reflex operating shadowless lamp
The 21st Century: LED shadowless operation light.
Modern Era
Intelligent and ulti-functional
Pay attention to intelligent, humanized design, with a variety of adjustment functions.
Main Types of Shadow-less Operation Light

The Parameters that Effect the Light Performance
⚫Light Source
Incandescent light, halogen light and LED light are widcly adoptcd as the light sources. But LED light has more advantages in various ways.
Our surgical lights are using the new LED cold light source. It is not engender infrared ray and ultraviolet radiation. Its halogen free won't cause temperature rise or tissue damage.
⚫Light Temperature
The color temperature of the operating shadowless lamp is usually between 4000 and 5000k, which can reduce the reflection and shadow of the operating area and improve the visual comfort and observation effect of the doctor.
MG CARE shadow-less operation lights has the range of light tempcrature from 3700 to 5000k.
⚫Color Rending Index (CRI)
The Color Rendering Index is a measure of the ability of its light source to render the true color of the object.
The higher the color rendering index, the stronger the color reduction ability of the operating shadowless lamp, which helps the doctor to bettcr observe the details and color characteristics of the operating area.
Generally, the CRI value of the surgical lamp is required to be 90 or above.
MG CARE shadow-less operation lights have the CRI range adjustable between 85 and 98.
⚫Illumination (Lux)
The illumination of the general operating shadow-less lamp can reach more than 150,000 Lux, which is close to the brightness under the summer sun.
MG CARE shadow-less operation lights have an adjustable illuminance range of 30,000-180,000 Lux.
⚫Spot Diameter
The larger the spot diameter, the better the shadow-less effect. The maximum spot diameter of the general surgical lights can reach 265 mm or more, and the minimum spot diameter is 150 mm or less.
MG CARE shadow-less operation lights have the spot diameter range from 160 mm to 280 mm.
⚫Illumination Depth
Most shadow-less operation lights have an illumination depth of 70-140 cm or 60-130 cm. The larger the diameter of the lamp holder or the greater the number of lamp holders, the deeper the illumination depth.
MG CARE shadow-less operation lights have the illumination depth of 50-180 cm.
