Research and Development of Shadowless Lamp

The importance of shadowless lights

Shadowless lamp is one of the most important medical equipment in the operating room. Through the use of shadowless lamp, medical staff can achieve the purpose of shadow-free illumination at the patient’s operation site, thereby helping doctors to clearly distinguish the lesion tissue and complete the operation smoothly.

At present, most hospitals in China are using traditional integral reflection shadowless lamps, which are also commonly known as halogen lamps because they usually use halogen light sources. According to the equipment exhibition (Medica) and the Beijing International Medical Equipment Exhibition (China Med), the major shadowless lamp manufacturers are focusing on their new LED shadowless lamp products. It is almost difficult to find halogen lamps at the exhibition site, and LED shadowless lamps replace Halogen lamps have become an unstoppable trend.

Advantages of LED shadowless lights

Compared with halogen lamps, LED shadowless lamps use a brand-new technology platform. Its emergence is accompanied by the continuous development and maturity of LED technology. Now the chip design and packaging technology of LEDs can fully meet the requirements of shadowless lamps in terms of illumination and At the same time, LED also has the advantages of long life, environmental protection and low energy consumption, which meets the requirements of the overall green lighting of the current hospital. In addition, the spectral distribution of the LED light source also determines that it is very suitable as a light source for surgical shadowless lamps.

Super long service life

The halogen bulbs usually used in the overall reflection shadowless lamp have an average lifespan of only 1000 hours, and the lifespan of the more expensive metal halide bulbs is only about 3000 hours, which makes the bulbs of the overall reflection shadowless lamp need to be replaced as consumables. The LED bulb used in the LED shadowless lamp has an average service life of more than 20,000 hours. Even if it is used for 10 hours a day, it can be used for more than 8 years without failure. Basically, there is no need to worry about the replacement of the bulb.

Environmental

Mercury is a highly polluting heavy metal. 1 mg of mercury can pollute 5,000 kg of water. In halogen bulbs and metal halide bulbs of various specifications, the mercury content ranges from a few milligrams to tens of milligrams. In addition, its service life is short, a period of time. After time, a large number of medical wastes that may cause serious pollution to the environment will be produced and accumulated, which brings great trouble to the post-processing of the hospital. The components of LED bulbs include solid semiconductors, epoxy resins and a small amount of metal, all of which are non-toxic and non-polluting materials, and can be recycled after their long service life. In the current era of more and more attention to environmental protection, compared with the two, LED shadowless lights will undoubtedly become the new choice of the times.

Low radiation and low energy consumption, conducive to postoperative wound recovery

Whether it is a halogen bulb using the principle of incandescent light or a metal halide bulb using the principle of high-voltage gas discharge, a large amount of thermal energy is accompanied during the lighting process, and a large amount of infrared and ultraviolet rays are generated at the same time. These thermal energy and radiation not only increase unnecessary energy consumption. , but also brought many adverse effects to the operation. The accumulated large amount of thermal energy will affect the service life of the devices in the lamp cap including the bulb itself, and will endanger the safety of the circuit in the lamp cap. The radiation will reach the surgical wound with visible light, and a large amount of infrared rays will cause the wound tissue to rapidly heat up and dry, and the tissue cells will be dehydrated and damaged; a large amount of ultraviolet rays will directly damage and kill the exposed tissue cells, which will eventually cause the patient’s postoperative complications. Recovery time is greatly extended. The principle of the LED lamp is to use the injection current to drive the carriers to combine with the holes through the P-N junction and release the excess energy in the form of light energy. This is a gentle process, and the electric energy is almost completely converted into visible light, and there is no excess heat. In addition, in its spectral distribution, it contains only a small amount of infrared rays and no ultraviolet rays, so it will not cause damage to the tissue of the patient’s wound, and the surgeon will not feel discomfort due to the high temperature of the head.

In recent days, the State Food and Drug Administration’s Announcement (No. 1) (No. 22, 2022) on the release of the results of national medical device supervision and sampling shows that the registrant (agent) is Shandong Xinhua Medical Equipment Co., Ltd., and the specification and model are The SMart-R40plus surgical shadowless lamp product, the central illuminance and total irradiance do not meet the regulations.

Our company has been strictly controlling the quality of the brand for more than ten years, and has further improved the quality. The reason why it can achieve the good-looking appearance of the streamlined design is because the Pepton team dedicatedly developed the shadowless lamp, so that it can achieve the “aesthetics” of the process and meet the requirements of modern operating room flow. Phipton shadowless lamp is an ultra-high-density led light source matrix with excellent shadowless effect, which is more suitable for the operation of medical staff, and the independent control panel is more convenient to operate, and it is not easy to distract doctors from the light source problem.
