At that time, the operating room was built in a southeast-facing room with excellent daylight, and windows were opened in its roof. But the biggest problem is that the operation time must be a clear day, which is greatly affected by the weather, and the light is easily blocked by the doctor. By installing mirrors in the four corners of the ceiling of the operating room, the use of mirrors to reflect sunlight can make the operating table more light. adequate.
This simple idea is simple and practical, but due to the limited technical level and materials at that time, it is impossible to design a modern surgical shadowless lamp.
The world’s first shadowless lamp
In the 1920s, French professor Weilan made the earliest surgical shadowless lamp in England. He evenly placed many narrow flat mirrors on the dome of the shadowless lamp, and placed a 100-watt light bulb in the center of the diopter lens. The emergence of the shadowless surgical lamp freed the surgeon from the dilemma of performing surgery at the sight of the sky. Later, the principle and shape of the shadowless lamp were used in this way.
In the 1930s and 1940s, the shadowless lamp had a second reform, and the single-lamp shadowless lamp in France and the track-type shadowless lamp in the United States appeared. At that time, the light source used incandescent light bulbs. The maximum power of the light bulbs could only reach 200W. The area around the filament was large, the light path could not be controlled, and it was difficult to focus.
LED cold light shadowless lamp
In the 21st century, LED cold light shadowless lamp came out.
In the 21st century, the details of surgical shadowless lamps have been continuously optimized. In addition to the improvement of basic performance parameters such as illuminance, shadowlessness, color temperature, and color rendering index, there are also strict requirements for illuminance uniformity. In recent years, LED light sources have been used in the medical industry, which has also brought new opportunities for the development of surgical shadowless lamps. It has the characteristics of excellent cold light effect, excellent light quality, stepless adjustment of brightness, uniform illumination, no screen flicker, long life, energy saving and environmental protection.
Compared with halogen lamps, LED as a cold light source can obviously control the temperature rise, the utilization rate of light energy conversion is high, there is almost no heat radiation, and the service life is 60 times longer than that of halogen lamps, which is economical and practical.
With the continuous emergence of new technologies and new materials, in the future, surgical shadowless lamps will have further development, even beyond our imagination.
Fepdon Geeta shadowless lamp
The way to smart lighting
In the case of different obstacles, through the mapping lighting method, Geeta650 shadowless can supplement the light source at different angles, improve the brightness of the light source, and finally achieve 98% shadow-free lighting effect.
Independent endo light source
Geeta650 is equipped with a one-button switch endo mode, which is faster to use. In endoscopic surgery, the Led handle allows medical staff to have better and more convenient lighting conditions, and will not cause distraction of the doctor.
Advantages of shadowless lamps
Appearance design that combines practicality and beauty
The light intensity can be controlled through the panel
Does not damage the sterile area Resists aging Not affected by lighting or daily cleaning
The handle of the lamp holder is convenient and detachable, which is convenient for soaking and high-pressure sterilization
Fepdon Woosen shadowless lamp
The overall aluminum alloy metal shell has good heat dissipation and effectively delays the LED light decay.
The streamlined design meets the laminar flow purification requirements of modern operating rooms and is also easy to clean.
Ultra-high density LED light source matrix, with excellent shadowless effect.
The 800 lamp head has a large light spot with infinite adjustment to meet the needs of more surgical lighting.
The intensity of the light can be controlled through the control panel, which is convenient and quick to operate.
The light-transmitting plate of the lamp head is durable and anti-aging, which can effectively reduce the decrease in light transmittance caused by lighting or daily cleaning.
The light head handle is easily removed for easy immersion or autoclaving.
Color temperature
The color temperature has five levels of control adjustment from 3800 to 5500, which can better help surgeons find photos with a suitable color temperature and even distribution.
