Trumpf iLEd surgical light offer color-change benefits
An LED-based surgical light allows surgeons to change the color temperature according to the type of procedure.
Trumpf Medical Systems has received FDA approval to proceed to market in the US with its iLED surgical light. The Trumpf iLED uses 184 white and colored LEDs to provide 160,000 lux of virtually shadow-free illumination, while the absence of forward heating due to IR radiation enhances the comfort of the surgical team.
The combination of LEDs allows the surgical team to change color temperature, which offers huge advantages for studying human tissue. At 3,500 K, skin and light tissue parts reflect less and the contrast remains intact. Colder light colors (up to 5,000 K), however, were preferred in tests for deeper lying body areas and for longer surgeries.
"Because of its adjustable color temperature, iLED offers excellent contrast representation," explained Professor Friedrich Hennig, Head Surgeon of the Department for Emergency Medicine at the University Clinic in Erlangen, Germany. Regardless of whether surgeons are operating on tissue in which the blood flow is heavy or light, they can make the contrast more visible by changing the color temperature.
