osram introduced borderless led instead of fluorescent tubes
The DURIS S 2 LED is a chip-scale package that provides uniform illuminationOSRAM Opto Semiconductors introduces the DURIS S 2, a compact version of the non-classical package, to further expand the Duris portfolio. DURIS S 2 is a low to medium power output range, typical luminous efficiency up to 160lm / W, with excellent color uniformity and color stability. Therefore, it can be used in the design of fluorescent lamp replacement products for LED products, to achieve uniform illumination. OSRAM Opto Semiconductors has expanded its DURIS product portfolio with the introduction of the compact DURIS® S 2, a non-classical package. DURIS® S 2 is a low to medium power output range with typical luminous efficiencies of up to 160 lm / W for superior color uniformity and color stability. Therefore, it can be used in the design of fluorescent lamp replacement products for LED products, to achieve uniform illumination.Thanks to the compact package size (only 2.0mmx1.6mm), this compact LED becomes the ideal light source for linear lighting solutions. As a chip-sized LED, its emission angle of 150 °, compared with the classic package of LED, launched to the side of the light more. As a result, it helps the linear bulb and fixture achieve better light distribution and reduces hot spots (visible light spots). This means that the number of LEDs can be reduced and the cost can be reduced. The new DURIS® S 2 LED has overdrive capability of up to 150mA and can be extended to include embedded ceiling fixtures and panel lights.S2 is the first OSRAM LED with a new lead frame material (an epoxy molding compound). “Thanks to this material, DURIS® S 2 has a 50,000-hour service life, compared to its sister DURIS® E3 (35,000 hours),” said Tony Tam, Project Manager and head of the DURIS product family at OSRAM Opto Semiconductors in Germany. And other existing DURIS® LEDs have a longer service life, “added Tam:” We are going to introduce other products that use this technology. “S2 size is only 2.0mmx1.6mm, DURIS product family is the most compact LED. Together with the existing S5 and S8 versions, this new product forms the DURIS product family. The new DURIS® S 2 offers a wide range of color temperature versions, 3000K, 3500K, 4000K and 5000K. From the summer of 2015, will also launch color temperature between 2700 ~ 6500K between the other versions. At present, the new LED is undergoing various quality tests. The certification process based on the LM-80 standard (ENERGY STAR) has been initiated.
