Rectangular LED provides camera flash for smartphones.
June 8, 2012 -
Utilizing 2 chips with 1 mm˛ emitting surface each, Oslux LED has flat surface that blends with cover of phone, facilitating inconspicuous installation. Symmetrical emission enables LED to be installed vertically or horizontally. Light is evenly distributed and covers corners of rectangular illuminated image, so no hot spot is generated in center as with conventional flash. With UX:3 chip technology, brightness level of 150 lux is achieved at distance of 3.3 ft.

New flash LED from Osram Opto Semiconductors harmonizes form and function
Osram Opto Semiconductors has added a new LED to the already popular Oslux family. This LED is specifically designed for camera flash in smartphones and provides a high quality white light that illuminates the target area. Due to its specially shaped lens that allows it to be discreetly fitted into the device, design compromises for flash applications are eliminated. This enables perfect marriage 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. 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. With the new Oslux LED for flash applications, Osram Opto Semiconductors supports smartphone manufacturers in their efforts to combine form and function. According to Matthias Winter, responsible for marketing LEDs for consumer applications at Osram Opto Semiconductors, "These days, more than ever, a smartphone is a symbol of fine design. With the new Oslux LED, we bring form and function together in a new and meaningful way."
The Oslux LED has two chips of 1 square millimeter of emitting surface 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. This means the Oslux LED can be installed inconspicuously. No additional covers or lenses are necessary. With its symmetrical emission, the Oslux LED can be installed vertically or horizontally. When switched off, the LED is barely noticeable. When in use, high quality white light illuminates the target area.
Thanks to UX:3 chip technology, the Oslux LED provides very consistent illumination for photos. At a distance of 1 meter (approx. 3.3 feet), a brightness level of 150 lux is achieved. The light is evenly distributed and covers the corners of the rectangular illuminated image. This means 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 Oslux LED is also easily integrated into the phone. And, thanks to its compact design, the LED is exceptionally durable and resistant to shock and vibration. Its energy efficient design makes even multiple consecutive flashes possible.
The new Oslux joins the current Osram portfolio of flash LEDs with lenses. The Ceramos LED family offers components without lenses.
