Osram Opto Launches LED Component for Medical Lighting

When it launches the new Osram Ostar Medical, Osram Opto Semiconductors will be introducing the first LED component with a high color-rendering index (CRI) of 95 and the possibility of adjusting the temperature of the color white. This makes it ideal for medical applications – for instance 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. This 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. This combination of precise chromaticity coordinate control and excellent CRI is particularly 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 particularly true-to-life – ideal for light systems in operating rooms.

Measuring just 5.9 mm x 4.8 mm x 1.2 mm, the Osram Ostar Medical has a very compact design. (LEDinside/ Osram)

Compact dimensions, simple to install

With a footprint of just 5.9 mm x 4.8 mm and a housing height of 1.2 mm, the design of the Osram Ostar Medical is very compact. Indeed, it is only 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.

“Compact luminaires prevail in the modern medical lighting sector and the low height of the new Ostar Medical makes it the ideal product,” explained Wolfgang Schnabel, who is in charge of marketing the product at Osram Opto Semiconductors. “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.
