LED family where the application determines current
The Oslon Square LED family can be used in a wide range of applications, from cool designer luminaires to bright street lights. And there is no need to change the manufacturing process for the lamps because this new LED has all the credentials for widespread use – it is small, powerful and capable of operating on different currents. Available in a broad range of different versions with different color temperatures, the LED can therefore be used for manufacturing different products for different target markets.
Like the Osram’s popular Oslon SSL LED, the Square measures 3 x 3 mm, has a thermal resistance of 4 to 3.8 K/W and is accommodated in a robust package suitable for outdoor use. Through its package design, a high system efficiency can be achieved: The LED chip is enclosed by a reflective package that reflects light emitted at the side or at the back so that this light is usable. Light that is reflected back to the LED within a system – for example from a diffuser – can also be used in this way.
with the Oslon Square EC version, the vendor tackles a range of indoor applications With a color temperature of 3000 K it provides a warm white light and also offers high color stability over a viewing angle of 120 degrees. The CRI is at least 80, Osram promises. 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. Ata current of 350 mA its efficiency even 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 it benefits from its reflective package, both individually and within a system.
The Oslon Square PC and UW versions 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 color 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, describes the extraordinary broad application spectrum: “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 color temperatures with different CRIs and can be operated with different currents."
The company plans to add further color temperature versions to the Olso Square portfolio in the near term.
