OT- light LED 5 MC

MC models are equipped with Multi-Colour-chips. The use of different-coloured
LED-chips allows the surgeon to change the colour temperature of the
OT-light depending on the preference for a more cold-white light (colour temperatures ≥ 4500 K)
or for a warm-white OT-light (colour temperatures ≤ 4250 K). The surgeon can set the
colour temperature according to the tissue structure, the surgical application and individual
colour sensitivity. This way we avoid tiredness during work: for instance, dazzling effects
can be avoided after longer interventions by using a warmer
light. On the other hand it is possible to increase the contrast by using higher colour
temperatures, which supports the surgeon’s power of concentration.

Dr. Mach already merges the different coloured LED’s by a computercalculated
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.

surgery to change the light colours 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 right-turn of the ring at the sterilisable handle.

* The LED-OT-lights can be equipped optionally with different colour
temperature ranges, e.g. from 3500 K to 5000 K.

A multitude of computer-calculated facetted lenses guarantees homogeneity
and lowest shadiness in the light field.
Separately arranged optical systems, each with four LED modules (Multi-
Colour models) or each with one LED module (Single-Colour models),
generate their own light field, which increases the contrast effect of the
OR light. Light intensities of 160.000 Lux can be attained without difficulty.

With colour rendering indexes Ra above 96 and R9 (red) above 90 the
surgeon recognizes clearly the tiniest nuances of colour in tissue. The colour
rendering index for SC models is Ra = 95. 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 visibly 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.

You have the possibility to increase the light intensity of the central segment
of the OT-light. This enables an optimum illumination of the wound field
according to its texture and the shadowing effects.
A high and adequate light intensity is very important especially in cases of
narrow and deep wound channels.
