Flash Osram announces smaller and brighter LED
The new UX:3 chip enables the LED to handle high currents and generate even more light making it ideal for smartphone and cell-phone camera applications.
The latest Oslux LED from Osram Opto Semiconductors is said to be brighter and smaller than the previous generation Oslux and provide uniform light thanks to a chip employing UX:3 technology. Along with an optimized lens, this allegedly produces a 50 per cent increase in brightness over the first-generation Oslux.
With a height of 2.5mm (previously 3mm), it provides 150lux compared to its predecessor which emitted 100lux. With the light being evenly distributed over the surface, this should illuminate a wider area compared to previous chip technologies.
It is also claimed that the Oslux LED is more efficient at high currents than previous LEDs and offers excellent luminous efficacy in a small area and that the common dead spot in the centre of the illumination area is completely absent.
Gunnar Klick, marketing manager consumer at Osram Opto Semiconductors, said: 'Our Oslux is perfect for the fast-growing design-based smartphone and cell-phone segment. Even extremely thin phones can now be equipped with a powerful LED flash so they can deliver pictures of superb quality.’
The Oslux LED is available with two different lenses that determine the percentage of centre brightness (20 per cent or 40 per cent) distributed to the corners of the flash area.
At a distance of 1m, the LED flash is said to uniformly illuminate the subject in a rectangular area of 90cm2 , and is enough to produce sharp pictures even in low light conditions.
The selected lens is integrated in the LED and matched to the beam characteristics of the top-emitting UX:3 chips.
Osram also offers the Ceramos range to users who wish to supply their own lens packages. This is a bright lens-free flash LED.
