November 29, 2011 -- OSRAM Opto Semiconductors introduced the Oslon Square LED for lighting applications, packaged enclosed in a reflective layer to boost light output.
The reflective package technology increases system efficiency, redirecting light from the side and back of the LED chip to the front. Light that is reflected back to the LED within a system, for example from a diffuser, can also be recycled in this way. At an operating current of 700mA, it achieves an efficiency of above 90lm/W and a luminous flux of 200lm and more. At 350mA, its efficiency exceeds the 100lm/W mark.

The Oslon Square is available in various versions and color temperatures, and can be operated with different currents. The Square measures 3 x 3mm, has thermal resistance of 3.8–4.0K/W and is suitable for outdoor use, as well as office lighting and retrofits. With a color temperature of 3000K, the Square provides a warm white light and offers high color stability over a wide viewing angle (120°), with a color rendering index (CRI) of at least 80.
The Oslon Square PC and UW are designed for outdoor applications, operated on currents of 200 mA to 1.5A, producing neutral white to cold white light with color temperatures of 4000 and 6000K. At 130 lm/W from 350mA they are even more efficient than the warm white version. With a CRI of at least 70 (4000K) and 65 (6000K), these LEDs combine high light quality with high efficiency.
