The device is ideal for medical applications such as in operating rooms, where a precisely controlled chromaticity coordinate and high natural color rendering are crucial.

The new Osram Ostar Medical comprises four different LED chips in the colors warm white, ultra white, verde and amber. The device permits customers to set the shade of white emitted by the LED according to their individual requirements within a color temperature range of between 3,700 and 5,000 Kelvin – and at a high overall CRI of 95. The combination of precise chromaticity coordinate control and excellent CRI is important for lighting in the medical sector. When optimized for the red spectrum (RaR9), the CRI remains at around 95 so that red shades are true-to-life – ideal for light systems in operating rooms.

The device has a footprint of 5.9 mm x 4.8 mm and a housing height of 1.2 mm and is about one-quarter as high as the components ordinarily used. The product owes its compact design to the flat, antireflex-coated glass cover with which the LED is equipped instead of the usual lens

The component is standardized, which means that customers can use the commonly available lenses. As with other members of the LED family, the Osram Ostar Medical is simple to install with standard soldering processes.
