Surgical light is also called operating light or a surgical lighthead. It is used to illuminate patient’s cavity or local area during the operation. In case a few surgical lights are used it is called a ‘surgical light system’.
The history of surgical lighting dates back to 1850s. The operating room had windows in the ceiling and was built towards the south-east. It was very inconvenient because the medical personnel or equipment could block the light, and the weather conditions could be unfavorable. Later on, the mirrors were placed on the corners of the ceiling so that they could reflect the light.
With the appearance of electric lights, the problem was partially solved. However, the first lights created great heat radiation and the emission of light was hardly controlled.
When light-emitting diodes (LED) were introduced, the problem of heat radiation was solved. Besides, such surgical lights consume less energy.
LED Surgical Lights
LED technology has a significant potential for energy savings and little maintenance. Compared to halogen lamps, LED surgery lights do not require filters to reduce the emission of non-visible radiation. Besides, halogen lamps work for 1000-3000 hours and fail suddenly without warning. LED lights work for 25,000-40,000 hours. When the lamps fail, they gradually fade.
Surgical LED lights have several more benefits:
- they radiate little ultraviolet or infrared energy;
- less voltage is necessary in order to produce equivalent light levels;
- one can use dimming with no change in color or flicker, and it can yield energy savings;
- LEDs decrease shadows cast ;
- some products offer color adjustment.
However, LEDs have a few disadvantages:
- LEDs must be used away from substantial thermal energy;
- such kinds of lamps are relatively expensive;
- independent test data are not generally available.
The medical personnel must make thorough examination of LED surgery lights and review work instructions before use.
