Surgical professionals now demand so much more than simple illumination from their operating theatre lighting. State of the art theatre lighting must offer advanced performance that eliminates shadows, provides true colour rendering so vital in determining the condition of patients, delivers light with an absence of the heat that is both uncomfortable for the staff and a threat to the patient, and offers low-maintenance energy efficiency to ensure competitive thru-life costs.
This complex performance specification can be achieved with the range of Steris XLED lighting available to hospitals and clinics in Britain and Ireland exclusively through Bender UK with dozens of the systems already in operation.
Steris has developed the XLED lighting system to provide cutting edge performance for surgical environments. XLED rethinks the surgical lighting concept with its design, offering the ideal intensity and quantity of light for each application, including endoscopic procedures, and delivering up to 160,000 Lux.
LED lamps do not emit infrared rays, so virtually no heat is radiated towards the surgical field. As a result, the risk of drying out exposed tissue is minimised and the conditions for the patient and surgical team are cooler and more comfortable.
LED lighting is hugely more energy efficient than conventional lamps in terms of the energy used in generating the required lighting performance, but the system also cuts the running costs for the facility because LEDs do not generate heat that must then be removed by air conditioning.
The Steris XLED lamps are specifically engineered to emit white light and thus avoid the need for filters to counteract the negative effects characteristic of colour LEDs. The system provides excellent natural colour rendition that remains stable over time, allowing surgeons to interpret tissue and vessel appearance with the utmost accuracy. Moreover, Steris has maximised the system’s R9 value, a measurement of critical importance as it determines the eye’s ability to distinguish subtle shades of red.
The modular system offers a choice of 1, 2, 3 or 4 spots to meet every surgical need. Each spot array of 20 LEDs is configured to optimise the laminar flow of light, producing patterns perfectly arranged to remove shadows, ensure excellent colour rendering and maintain even illumination, eliminating the rainbow effects that can lead to visual fatigue.
The exclusive Wavelens system available as standard on XLED3 and XLED4 can instantly adjust the pattern diameter through beam divergence to maintain lighting quality without refocusing or repositioning the head.
Each XLED spot is mounted on a lightweight and balanced system for easy positioning and offers a single cardanic gimble version for operating theatres with low ceilings. The system offers dual controls which are directly accessible from the lighting suspension or using the wall-mounted theatre control touchscreen.
The system is designed to integrate adjustable spot size in-light cameras and accommodate future technologies, making it easier to add equipment or upgrade to emerging technology.
