Reasserting its market position in camera flash LEDs while at Mobile World Congress, Lumileds has introduced the LUXEON Flash 9X with Spectral Pure Technology LED that produces photos with high colour quality. Noted for its small form factor (1.4x1.4mm chip scale package), this robust LED is suited to produce photos with vivid colours including the most realistic skin tones captured on any smart phone.

Thierry De Smet, Director of Product Marketing at Lumileds, said: “The improved picture quality with Spectral Pure Technology is stunning when compared side-by-side with photos captured at 80 CRI, the former industry standard. Pictures taken with LEDs supported by Spectral Pure Technology have richer colours and facial tones appear more attractive than before.”

Key to this exceptional colour quality is the spectral optimisation of the camera flash, which matches the camera response curve and is characterised by its Camera Color Index (CCI), a more effective metric Lumileds is introducing to replace Color Rendering Index, CRI, for camera applications.

“CRI really only applies when viewing objects directly with the human eye, but a camera captures colours differently, and the flash should be designed to counter this difference,” added De Smet.

The LUXEON Flash 9X with Spectral Pure Technology is a high power LED that features industry leading flux of 240lm at 1A drive current and 25C, and is hot flux stable at higher currents. The flash is produced at 4500K colour temperature with excellent colour stability of ±250K. Lumileds provides the highest reliability devices with the industry’s first 1:1 LED traceability.
