Osram launches Oslux LED for smartphone camera flash

Osram Opto Semiconductors GmbH of Regensburg, Germany has added to its Oslux family with a new LED designed specifically for the camera flash in smartphones, providing a high-quality white light that illuminates the target area. The firm says that, due to its specially shaped lens that allows it to be discreetly fitted into the device, design compromises for flash applications are eliminated, enabling a combination of design and function when it comes to using LEDs in smartphone camera flash applications.

Manufacturers of high-end smartphones often have to choose between design and functionality, says Osram Opto. A particular challenge is combining the actual camera with the lighting needed. In some designs the technical components can look bulky and the recesses in the enclosure can also make the device less robust. Osram Opto says that, with the new Oslux LED for flash applications, it supports smartphone makers in their efforts to combine form and function.

The Oslux LED has two chips with an emitting surface of 1mm2 each. The light-emitting area of the rectangular LED is optimized for the optics of the phone – the surface is flat and blends properly with the cover, so the LED can be installed inconspicuously. No additional covers or lenses are necessary. Also, due to its symmetrical emission, the Oslux LED can be installed vertically or horizontally.

Due to Osram Opto’s UX:3 chip technology, the Oslux LED provides consistent illumination for photos, the firm claims. At a distance of 1m, a brightness level of 150 lux is achieved (at a drive current of 320mA). The light is evenly distributed and covers the corners of the rectangular illuminated image. So, no hot spot is generated in the center, as would be the case with a conventional flash. As all the elements of the flash are combined in a single component, the LED is also easily integrated into the phone. In addition, due to its compact design, the LED is durable and resistant to shock and vibration. Its energy-efficient design makes also multiple consecutive flashes possible.

The new Oslux joins the existing Osram portfolio of flash LEDs with lenses. The Ceramos LED family offers components without lenses.
