Osram announces multi-chip LED with lens for camera flash
Oslux module provides uniform illumination of photos and video recordings
Osram Opto Semiconductors has integrated two LED chips and a lens into a single module for camera flash applications. With its brightness of 125 lux, the Oslux S 2.1 is designed to provide uniform illumination of photos and video recordings from mobile devices such as smartphones.
The Oslux S 2.1 for camera flash applications combines two chips of different colour temperatures: a cold white chip with 6,000 K, and a warm white chip with 2,250 K (Dual-CCT), providing both a multi-chip LED and a lens for the first time.
This not only makes manufacturing easier by saving a step, but also produces excellent results. The chip has a maximum deviation of 300 K, resulting in good colour fidelity and uniformity across the target scene. While dimensions of 5.0 mm x 5.0 mm x 1.15 mm make the Oslux S 2.1 with its lens slightly taller than previous models, it requires less space on the board and has a smaller exposed aperture than two single LEDs, making it overall a more compact solution. The silicone lens also allows this module to be reflow solderable, allowing the module to be easily integrated into standard manufacturing flows.
"With the new Oslux S 2.1 we were able to achieve very high quality. We have subjected it to both electrical and optically demanding testing and are very happy with the results. It definitely meets our high quality standards," said Russell Willner, product marketing manager at Osram Opto Semiconductors.
