LED surgical light
Surgical light realised with MULTI COLOUR OSTAR Projection LED technology.
The new OT-light generation with LED technology supports your professionalism by innovative technology and design. The advantages of the LED technology: adjustable light colour, a life-span of minimum 25.000 hours, superior colour rendition with a previously unattainable colour rendition Ra = 95 and R9(red) = 90 and an almost nonexistent heat development in the surgeon's head area and in the wound field.
Colour composition inside the light head
The luminaire already merges the different coloured LED's by a computer calculated optical system with light guide and facetted lenses. This means: The composed light leaves the optical system as white light and is dispersed over the wound field homogeneously. Colour shadows in the light beam of the OR light caused by the surgeon's head, shoulder or hands are avoided by the colour composition in the optical system.
Facetted multi-lens system
A multitude of computer calculated facetted lenses guarantees homogeneity and lowest shadiness in the light field. Forty separately arranged optical systems, each with four LED modules, generate their own light field, which increases the contrast effect of the OR light. The maximum light intensity is 160.000 Lux.
Changing the light colour
The use of different coloured LED's allows a change of the light colours in surgery depending on the application. The surgeon has the possibility to choose the optimum OR light according to the tissue type and the wound field texture. Five different colour temperature values can be set: 3750, 4000, 4250, 4500 and 4750 Kelvin. The setting can be done either at the key pad on the lamp housing or by a left-turn of the ring at the sterilisable handle.
Superior colour rendition
With a previously unattainable colour rendition Ra = 95 and R9(red) = 90 you easily see the tiniest nuances of colour in tissue. For recognizing the exact colour spectrum of the wound the exact rendition of the red colour range is essential. R9(red) = 90 means for the surgeon a visible better recognition of details. The colour spectrum of the wound is rendered naturally with rich contrast. The OT-light clearly provides welcome relief for your eyes.
Cool light
The LED technology is much more effective than conventional light sources such as halogen bulbs. The heat radiation is reduced to a minimum without using any expensive filter technique. The temperature increase in the surgeon's head area is almost nonexistent.
Long life-span
The life-span of more than 25.000 operating hours reduces the costs for exchanging and replacing the illuminants considerably, compared with the conventional halogen technology used with former OT-lights.
