HyLED 9 SeriesLED Surgical Lights One of the main features of LEDs is their potentiallyvery long life. Electrical and thermal design of the LED system or fixturedetermine howlong LEDs will last and how much light they willprovide.With improved electricaland thermalrobustness ofLEDs, HyLED service life is up to 40,000 hours, which is 40 timesthan halogen bulbs. Sensor control function: once the area is masked by surgeon's head,the lighting of the remaining zones are automatically boosted to maintain the consistent central illumination, so there is noneed to make adjustments to the HyLED during a surgical procedure Safe and consistent lighting ofthe operating field Free movement ofsurgeons True shadow-freeillumination Less heat around surgeon's head and the operative field, temperature rise less than 1"C This "Cross" shape oflight head can be put in a proper position, which makes doctors heads in the four corners. And it alsocan provide you a homogeneous light beam & light patch, just like the picture shows you. Minimum light field diameter of 195mm Maximum light field diameter of 330 mm Optimized air flow design for better hygieneHyLED generates minimized turbulence in the laminar flow in two ways: first its cross shape design ideally matches withaminar flow;second,its low power consumption and excellent heat dissipation make the warming efect on the outersurface is really low. 5o,HyLED creates optimum operating conditions and fulfills hygiene requirements.
