In January this year, a small number of patients at an Oregon hospital suffered from skin irritations and burns due to unfiltered halogen operating room lights. Though the hospital was quick enough to address the issue, it raises the question of safety of the halogen lamps. It is estimated that the global surgical lamps market will be worth US$728,915.2 thousand by 2020. Apart from providing optimally bright and shadow-free high-intensity light during surgical procedures, surgical lamps are must be energy-efficient with minimum infrared and ultraviolet radiation.
Advantages of LED Surgical Lamps
The U.S. Department of Energy’s Hospital Energy Alliance (HEA) acknowledged the improvements in light-emitting diode (LED) technology in 2010 and recommended LED surgical task lighting due to its improved efficiency and reduced emission of greenhouse gases. According to LUPUS UK, the usage of LED surgical lamps will reduce the emission of greenhouse gases by 80% by 2050. Over the last five years, LED technology has witnessed rapid developments.
Following are the potential advantages of LED surgical lights:
Efficacy: LED surgical lamps need less wattage to produce equivalent light levels.
Lesser Radiation: LED surgical lamps radiate relatively little ultraviolet or infrared energy.
Energy Savings: LED surgical lamps can be dimmed without color shift or flicker, thereby yielding additional energy savings.
Maintenance: LED surgical lamps have greater lives with non-catastrophic failure mechanism.
Why the Shift from Halogen to LED Lamps?
Halogen lamps, which have been commonly used in surgical task lights, have relatively low luminous efficacy which is worsened by filters that are used to reduce the non-visible radiation emitted by the halogen lamps. Moreover, halogen lamps last for around 1,000 to 3,000 hours and fail suddenly without warning. It is not surprising that in the global surgical lamps market, shift from halogen lamps to LED lamps is emerging as the latest trend.
The U.S. Food and Drug Administration has granted marketing clearance to the LED surgical lamps. However, the high cost of LED surgical lamps deters many surgical centers from using them, even though, over a long run LED surgical lamps reduce the energy bills at healthcare organizations.
Developments in LED Surgical Lamps
Traditionally, North America has been the major market for LED surgical lamps. However, LED surgical lamps market in Asia is rapidly growing with increasing patient pool and thriving medical tourism industry. To attend to the poor electrical infrastructure in the developing economies in Asia, battery powered LED surgical lamps have been introduced in the market. Key industry players such as Integra LifeSciences Corporation and Stryker Corporation have developed the battery powered LED surgical lamps for the Asian market. These lamps utilize high intensity LED technology to emit cool beam of pure white light. Being lightweight with adjustable positioning, the battery operated LED surgical lamps have life of more than 25,000 hours.
With more number of healthcare centers and hospitals adopting LED surgical lamps, patients can be hopeful of not getting injured or encountering untoward incidents due to halogen lamps in the operation rooms.
