First Multi-Chip Led with Lens Improves Camera Flash Applications: the Right Brightness for any Photo

Osram Opto Semiconductors introduces a new generation of its Oslux LED for mobile devices

For the first time, Osram Opto Semiconductors has integrated two LED chips and a lens into a single module. The compact Oslux S 2.1 multi-chip LED brings together all the company’s extensive technical expertise into a new LED product for camera flash applications. With its brightness of 125 lux, the Oslux S 2.1 provides uniform illumination of photos and video recordings from mobile devices such as smartphones.

Osram Opto Semiconductors’ new Oslux S 2.1 for camera flash applications combines two chips of different color 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. With a maximum deviation of 300 K, the Oslux offers remarkable color fidelity and excellent color uniformity across the target scene.

Perfect flash for the perfect photo

In video lights and camera flash applications, the integration of two LED chips and a silicone lens in one module offers clear benefits for the customer. Now, no separate step is necessary for optimum positioning of the lens, which saves time and optimizes the use of the generated light. 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.

Additional version planned for 2018

The Oslux S 2.1 is currently available. Osram Opto Semiconductors is planning to release an additional version in early 2018, the Oslux S 2.2. Instead of a silicone lens, it will come with an epoxy lens. Thanks to this extremely hard material, the Oslux S 2.2 can be installed in mobile devices without a separate protective window, providing additional industrial design options. What’s more, a spectrum-optimized converter will provide the Oslux S 2.2 with even better photos.
