Today’s surgical light must be flexible when it comes to movement and positioning, as well as intensity control, so that one surgical light is adaptable to different procedures. Operating room lights are important in a hospital because it must meet the demands of different medical personnel who may have varying medical lighting requirements. The use of a LED surgical light for medical lighting is not just about energy saving and reductions, it contributes to a lower, stable room temperature that helps maintain nomothermia in patients, which ultimately limits surgical site infection risks, aids in and improves wound healing, and promotes patient satisfaction and timely discharges with the added benefit of improving staff comfort.
Medical lighting systems generally include single and/or dual light heads that are attached to a boom arm or track suspension that is equipped with sufficient light reflection, spectral characteristics, focus, pattern and intensity adjustments to help greatly reduce the creation of shadows by operating room lights. Medical lighting helps to illuminate the subjects true color more accurately than that of bulb lights and has the added benefit of multiple arrangements of small light sources fixed at different angles to aid in shadow reduction for a more consistent surgical light, even when surgical personnel lean into the area of illumination created by the operating room lights.
Advances in medical lighting technology such as LED’s offer many advantages for use as operating room lights over traditional tungsten halogen and gas discharge fixtures which include reduced electricity use, longer life, reduced heat generation, and lower ultra violet radiation which helps to reduce the potential of creating dry, exposed tissue.
