Osram expands the Duris LED family for linear and area indoor lighting

Osram Opto Semiconductors has expanded its Duris LED family with "Duris S 5", which offers lifetime of more than 35,000 hours and can withstand much higher temperatures in the applications – up to 105 degrees Celsius (°C). Duris S 5 is suggested for indoor lighting – in retrofits, in downlights or in panel luminaires used in places such as offices, hotel lobbies and museums.. Osram says the package for Duris S 5 is made from robust synthetic material that is resistant to aging caused by high temperatures and short-wave blue light. “This innovative LED package makes the component robust and cost-effective. This is then reflected of course in the luminaire manufacturing costs for our customers”, said Janick Ihringer, Product Manager Marketing SSL at Osram Opto Semiconductors. The new Duris is being launched in three versions with different chip surfaces and therefore three different brightness levels. The first version is for large amount of light need to be emitted from a small surface area, for example in downlights and LED retrofits. At 3000 Kelvin (K) and a CRI of 80 the first version achieves very high brightness of 97 lumen (lm) and an efficacy of more than 100 lumen per watt (lm/W) at an operating current of 150 milliamps (mA). Its optimized forward voltage of around six volts (V) means that efficient driver solutions can be used that have a beneficial effect on...
