OSRAM Opto Semiconductors Launched New LED: the Oslon Square
Nov 30, 2011 Like the Oslon SSL, the Square measures only 3 x 3 mm, has a low thermal resistance of 3.8 – 4.0 K/W and comes in a robust package which is suitable for outdoor use. Particularly noteworthy is the high system efficiency that can be achieved with this versatile LED. The LED chip is enclosed by a reflective layer, which redirects the light emitted at the side or back of the LED, making it usable. Light that is reflected back to the LED within a system – for example from a diffuser – can also be recycled in this way.
The Oslon Square EC is perfect for applications that require high quality light, such as in office environments. With a color temperature of 3000 K, 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. At an operating current of 700 mA it achieves an efficiency of above 90 lm/W and a luminous flux of 200 lm and more. At 350 mA its efficiency exceeds the 100 lm/W mark.
The EC version is also suitable for retrofits. Thanks to its small dimensions it can be closely clustered and, like all the LEDs in this series, it benefits from its reflective package, both individually and within a system.
The Oslon Square PC and UW are designed for outdoor applications, such as street lighting. These versions can be operated on currents of 200 mA to 1.5 A, making them a good fit for other applications such as highbays, lowbays and spotlights. The LEDs produce a neutral white to cold white light with color temperatures of 4000 K and 6000 K. At 130 lm/W from 350 mA they are even more efficient than the warm white version. With a CRI of at least 70 (4000 K) and 65 (6000 K), these LEDs combine high light quality with high efficiency.
“Every application places different demands on lighting, and with the Oslon Square we are providing a platform for tailor-made solutions,” said Ivo Ivanovski, product manager for the Oslon Square series at OSRAM Opto Semiconductors. “The Oslon Square is available in different color temperatures with different CRIs and can be operated with different currents. By the end of the year we will have added further color temperatures to the portfolio. In addition to product features, we are offering logistical concepts with the Oslon Square that will make it easier for customers to develop luminaires.”
