Osram Opto Semiconductors has introduced new members of DURIS® S 8 family. The family is known as CHIP ARRAY SMD (CAS). The multichip family features a compact high power LED with high luminous flux. The LED which boasts high color consistency can operate at high forward voltage. The company says it offers new opportunities for all indoor and outdoor door lighting especially directional retrofit applications.
Low Costs and Enhanced Performance
Osram Opto Semiconductors says that it increased the performance of the second generation Duris S8 due to a new leadframe material and chip structure. Different versions of the second generation DURIS ® S 8 come in various lumen packages with the same foot print. The company optimized the multi-chip LEDs for consumer indoor and outdoor applications.
The new Duris S8 package measures 5.0 mm × 5.0 mm. Unlike the original Duris S8 with a round light emitting surface, the new generation Duris S8 features a rectangular light emitting surface with rounded corners. The diameter (length across this rounded corner square) of the light emitting surface on the new generation is just 4.6 mm.
Gen 2 Duris S8 Performance Specifics
According to the company, the LED’s small light emitting surface makes it ideal for directional lighting. Low thermal resistance enables higher operating power than the previous generation. The LEDs come with minimum CRI of 70, 80, and 90. Color temperatures of the new LEDs range from warm white (2700K) to cool white (6500K). The LEDs produce up to 600 lumens. Their typical efficiency at 3000K is up to 134 lumens per watt at 600 mA and 6.2 Volts of operating current. LM-80 test data for the new generation LEDs is available upon request.Potential applications for the new LEDs include retrofit (omnidirectional, directional, linear); home (pendant lighting, strip lighting, spotlight); shop (spotlight, downlight, linear lighting, freezer/display, shelf lighting); office (downlight, linear/area lighting);
Potential applications for the new LEDs include retrofit (omnidirectional, directional, linear); home (pendant lighting, strip lighting, spotlight); shop (spotlight, downlight, linear lighting, freezer/display, shelf lighting); office (downlight, linear/area lighting); architainment and hospitality (accent/mood lighting, cove lighting, strip lighting);industrial (portable lighting, emergency lighting, high/low bay, linear lighting); and consumer outdoor lighting.
