Oslux LED offers new design options for smartphones
Osram Opto’s new flash LED harmonises form and function Osram Opto has added a new type of LED to its Oslux family. With no need for flash applications to be compromised, Osram says its specially shaped lens makes its Oslux LED suitable for discreet fitting into a device. Thanks to its high output power, the new LED is also capable of capturing excellent illuminated shots using cellphones.

No conflict between functionality and design with the new Oslux LED
Much of the time, manufacturers of high-end smartphones have to choose between design and functionality. A major challenge in this case is combining the actual camera with the lighting needed. Technical components can look bulky with some cellphones. What’s more, the recesses in the enclosure also make the device less robust. According to Matthias Winter, responsible for marketing LED consumer applications at Osram Opto Semiconductors, “These days a smartphone is more than ever a design object. With the Oslux LED we bring form and function together.” With the new Oslux LED for flash applications Osram Optosays it is supporting smartphone manufacturers in their attempt to combine shape and function.
The Oslux LED has two chips with a square millimetre of light surface each. The light-emitting surface of the rectangular LED is optimised for the optics of the cellphone – the surface is flat and finishes properly with the cover.
This means the Oslux LED can be installed inconspicuously in the phone. No additional covers or lenses are necessary. With its symmetrical emission, the LED can be installed vertically or horizontally. When switched off, the LED is barely noticeable, but when in use, high quality white light illuminates the target area. Osram says its UX:3 chip technology in the Oslux LED provides very consistent illumination for photos. Even at a distance of 1m a brightness level of 150 lux is achieved. When flashing, the light is evenly distributed and shines into the corners of the rectangular illuminated image. This means no round spot is generated in the centre like what sometimes happens in conventional flashing. The elements of the flash are integrated into a single component, making the Oslux LED compact. Osram says it is also durable and resistant to shocks and vibrations and the high power means it can cope with multiple repeated flashes. With a luminous efficacy of 150 lux at 320 mA the module comes in a 9 x 6 x 2.9 mm package. It has a 1,062 x 808 mm illumination target window and the colour temperature is 4,500K.
