usable. Light that is reflected back to the LED within a system – for example from a diffuser – can also be used in this way.
The Oslon Square EC is suitable for indoor applications in which a high quality of light is needed, for example in offices. With a colour temperature of 3000 K it provides a warm white light and also offers high colour stability over a wide viewing angle (120°). The CRI is at least 80. If the lighting needs to be particularly uniform a “fine-bin” order can be placed for this LED. 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 passes the 100 lm/W mark.
The EC version is also suitable for retrofits. Thanks to its small dimensions of 3 x 3 mm 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, for example in street lighting. They can be operated on currents of 200 mA to 1.5 A, making them interesting for other applications such as downlights and spotlights. The LEDs produce a neutral white to cold white light with colour temperatures of 4000 K and 6000 K. And 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 good quality of light with high efficiency.
Ivo Ivanovski, Product Manager for the Oslon Square series at Osram Opto Semiconductors, summarised the benefits of the new LED as follows, “Every application places different demands on lighting, and with the Oslon Square we are providing a platform for tailor-made solutions. The LED is available in different colour 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,” concluded Ivanovski.
