‘Borderless’ LED for fluorescent tube replacement

1 July 2015 Opto-Electronics

OSRAM Opto Semiconductors is extending its Duris product portfolio with a compact version without a classic package. The Duris S2 is in the low to middle output range and offers a high typical luminous efficacy of 160 lm/W, with excellent colour homogeneity and colour stability.

It is therefore capable of achieving homogeneous illumination in LED products designed as replacements for fluorescent tubes.

Thanks to its compact footprint of only 2,0 x 1,6 mm, this space-saving LED is ideal for linear lighting solutions. With an emission angle of 150°, this chip-size LED emits more light to the side than LEDs with classic packages. The light is therefore better distributed in linear lamps and luminaires, and hot spots (visible points of light) are reduced. This in turn enables the number of LEDs and therefore costs to be reduced. By overdriving the Duris S2 up to 150 mA its range of applications can be extended to recessed ceiling luminaires and panel luminaires.

The first OSRAM LED to use a new lead frame material, an epoxy moulding compound, the Duris S2 has a long life of up to 50 000 hours. It is available in correlated colour temperatures of 3000, 3500, 4000 and 5000 K, with additional versions with colour temperatures of 2700 to 6500 K to follow.
