LED surgical lights-the latest trend of the shadowless lamp

Shadowless lamp is operating the most important medical equipment, medical staff, through the use of the shadowless lamp in patients undergoing fertilization parts no shadow lighting purposes, to help the doctor clearly distinguished focus tissue, successfully completing the operation.

At present, most of the hospitals in the country are using traditional overall reflection shadowless lamp, with its typically use a halogen light source also commonly known as halogen lamp, but from this year's domestic and foreign major medical equipment exhibition, including Germany, Dusseldorf medical equipment exhibition (Medica) and Beijing International medical equipment fair (China Med), shadowless lamp manufacturers have launched their new flagship LED the shadowless lamp product, the show could hardly find halogen lamp, LED the shadowless lamp replacement halogen lamp has become an irresistible trend.

Relative to the halogen lamp, LED the shadowless lamp uses a new technology platform, it is accompanied by LED technology continues to mature and, now LED by chip design and packaging technology has been able to fully meet the shadowless lamp in illuminance and color index requirements, while LED also has a long life, environmental protection, low energy consumption of benefits, in line with the current hospital overall green lighting requirements, in addition, the spectral distribution of the led light source also determines its ideal as the light source the shadowless lamp operation.

Long service life

Overall reflection shadowless lamp usually use halogen bulb, their average life expectancy is only 1000 hours, more expensive metal halide bulb life is only 3000 hours or so, this makes the overall reflection shadowless lamp bulbs need replacement as consumables.

And LED the shadowless lamp, LED lamp, average service life reach 20000 hours, even days 10 hours, or 8 years of trouble-free use, basic without worrying about the replacement of the lamp.

Green environmental protection

Mercury is a highly polluting heavy metal, 1 mg of mercury to 5000 kg of water pollution, in various specifications of the halogen bulb and metal halide lamp bulb, mercury content from a few milligrams to dozens of mg, coupled with its short life, for a period of time will have a large number of possible and accumulation of serious pollution to the environment of medical waste products to hospitals in post processing than the big bother.

The led bulb of component materials including solid-state semiconductor, epoxy resin and a small amount of metal that is non-toxic, non-polluting materials, in its long after the end of life can also be recycled. In the current environment protection and more emphasis on age, two-phase comparison, LED the shadowless lamp will undoubtedly become the era of the new selection.

Low emissivity low energy consumption, conducive to Postoperative wound recovery

Whether using incandescent light emitting principle of halogen bulb or using high pressure gas discharge principle of metal halide bulb, its luminous process with large amounts of heat, at the same time produce a large volume of infrared and ultraviolet radiation, heat energy and not only increased the unnecessary energy consumption, back surgery has brought many adverse effects.

Cumulative effect of a large number of thermal energy will include light bulb lamp holder within the device's own life, and which would endanger the security of the internal lamp holder. And radiation will arrive with visible light, surgical wounds of a large number of infrared rays cause wound tissue rapid warming and drying, dehydration and damaged tissues and cells; large amounts of UV are direct damage and kill the exposed tissue cells, eventually resulting in postoperative recovery time greatly extended. The LED light principle is to use injected current drive carrier through a combination of p-n junction and the hole and the extra energy to release the energy forms, this is a gentle process, almost all power into visible light, and no excess heat produced, but also in its spectral distribution, only contain a small amount of infrared and ultraviolet radiation, so do not exist will not give the organization in patients with wound damage, cancer doctors won't because head temperature rise too high and discomfort.

At present the domestic manufacturers, due to the technical bottlenecks using LED light source.

It is understood that focus on operating room and ICU total solution of Beijing friendship on company pioneered with led light source, has recently launched a high grade LED the shadowless lamp, may thereafter will lead the domestic operation a new era of lighting.
