Osram Opto Semiconductors launches a new generation of the Oslux LED for mobile devices. For the first time, two LED chips and a lens have been combined into a module.

The compact Oslux S2.1 multi-chip LED offers all the high-tech company’s wide-ranging technical expertise into a new LED version for camera flash applications. With its brightness of 125 lux, it offers uniform illumination of video recordings and photos from mobile devices such as smartphones.
The new Oslux S2.1 has been added into the company’s portfolio for camera flash applications. The two chips have different color temperatures, a warm white chip with 2,250 K (Dual-CCT) and a cold white chip with 6,000 K. This not only reduces a work step but also yields great results. With a full deviation of 300 K, the Oslux offers extraordinary color fidelity and outstanding color uniformity across the target scene.
Perfect flash for the perfect photo
In camera flash and video lights applications, the incorporation of two LED chips and a silicone lens on one PC board provides clear benefits for the user. Now, a separate step is not necessary for ideal positioning of the lens. This not only saves time but also enhances the usage of the generated light. Dimensions of 5.0 mm x 5.0 mm x 1.15 mm make the Oslux S2.1 with its lens marginally higher than predecessor models. The Oslux S2.1 needs less space on the board and has a smaller exposed aperture than two single LEDs, making it remarkably compact. The silicone lens allows this module to be reflow solderable, permitting the module to be easily combined into standard manufacturing flows.
With the new Oslux S2.1 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.

Additional version planned for 2018
The Oslux S2.1 is commercially available already. Osram Opto Semiconductors is planning on launching a new version, Oslux S2.2 in early 2018. The new one will have a silicone lens instead of an epoxy lens. Thanks to this very hard material, the Oslux S2.2 can be fitted into mobile devices without a separate protective window, which offers extra industrial design options. Furthermore, a spectrum optimized converter will provide the Oslux S2.2 with much better photos.
