OSRAM envelops LED chip in reflective package

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
