Newest Members of the DURIS Family of LEDs: DURIS S 5 and DURIS S 8

  

The two newest members of the OSRAM Opto Semiconductors' DURIS Family of LEDs are DURIS S 5 and DURIS S 8. These new LEDs have many features that make them ideal for numerous low and high power lighting applications. The DURIS S 5 is a compact, mid-power LED, while the DURIS S 8 is a compact, high-power LED, both with scalable luminous flux packages.  

 

DURIS S 5DURIS S 5: The Compact Mid-power LED for Longer Lifetime and More Efficiency

 

The DURIS S 5 is a new compact, mid-power LED with a 3 mm x 3 mm footprint that is available in three different luminous flux packages. It provides flexibility in forward voltage, luminous flux and efficacy and offers high lifetimes even at elevated temperatures.

 

Compared to polyphthalamide (PPA) packages, higher lifetimes can be achieved at higher solder point temperatures thanks to innovative package materials. The DURIS S 5 allows for various luminous flux packages within one LED package type, saving costs on secondary components within the luminaire. With its higher voltage option (6V), the DURIS S 5 optimizes driver efficiency and costs.

 

Features

  • Three different lumen options within one package size
  • Small footprint (3mm x 3mm) for clustering
  • Higher lifetime than PPA packages
  • Compact light source with a colored diffused silicone resin in a white SMT package
  • Viewing angle at 50% lv: 120�
  • Optimized driver efficiency and costs due to higher voltage option (6V forward voltage)
  • Color: 2700 K - 6500 K (white)
  • CRI: 85 (typ.)
  • Lumen maintenance: testing according to IESNA LM-80 in progress

  

 

 

 

 

 

 

 

 

 

Applications

  • Indoor general lighting
  • Industrial lighting
  • Linear lights
  • Professional downlights
  • Retrofits - directional, omni-directional and linear

DURIS S 8 is small, simple and smart

 

Small. Simple. Smart. The DURIS S 8 is a revolutionary compact high-power LED for indoor illumination, including directional and omni-directional retrofit lamps. As a new multi-chip member of the DURIS S LED series, the LED's high luminous flux, high forward voltage and high color consistency from only one small LED package allows for completely new opportunities for indoor lighting applications.

 

The new DURIS S 8 emits a great deal of light from a small surface area, creating efficient optical solutions. It measures just 5.8 x 5.2 mm and is available in six- or eight-chip versions, allowing for different lumen packages from one LED type, eliminating the need for numerous LEDs. This saves cost within the luminaire, reducing assembly efforts and simplifying logistics.

 

Compared to PPA packages, DURIS S 8 also offers higher lifetime and higher possible solder point temperatures thanks to a package consisting of an innovative plastic housing material that is resistant to aging due to high temperature and short wavelength (UV) light, but also costs less than the ceramic housings more frequently used. With a luminous flux of 500 lm at 200 mA, the LED can be used in retrofits such as MR16 and PAR16 replacement lamps. The close grouping of the LED die allows for excellent color consistency in combination with high lumens, corresponding to a three-step MacAdam ellipse with a CRI greater than 80. The DURIS S 8 is grouped at a junction temperature of 100 �C for an effortless design in.

 

Features

  • Three different lumen options within one package size
  • Small Light Emitting Surface (LES) improves optical behavior in directional lighting
  • Low thermal resistance enables excellent thermal performance
  • High operating temperatures of up to 110�C solder point temperature permitted
  • Small footprint for clustering
  • Higher lifetime than PPA packages
  • Optimized driver efficiency and costs due to higher voltage option
  • Compact light source in white SMT package, colored diffused silicone resin
  • Viewing angle at 50% lv: 120�
  • Colors: 2700 / 3000 / 4000 K (white) (3500 / 5000 / 5700 / 6500 K available soon) 

 

 

 

 

 

 

 

 

 

Applications

  • Directional retrofits, such as MR16, PAR16, AR111
  • Downlights
  • Spotlights
  • Omni-directional retrofits

New Application Notes

Three new application notes have recently been added to our website.  These new application notes are informational and useful for product developers, design engineers, optical engineers, managers, students, lighting specifiers and application engineers.  The titles of the application notes are: PCB (Printed Circuit Board) Technologies for LED Applications, The Basic Principles of Electrical Overstress (EOS) and Thermal Management of Light Sources Based on SMD LEDs.

PCB Technologies for LED Applications provides a general survey of the various available Printed Circuit Board (PCB) technologies for use in LED applications. Thanks to direct conversion of electrical current to light (optical radiation) within the semiconductor material, LEDs are more efficient than most traditional light sources. This application note summarizes why PCBs need to be individually designed according to the specific assembly and specific requirements of the complete system.

The Basic Principles of Electrical Overstress (EOS) describes the principles of one common failure mode of LEDs - electrical overstress.  LEDs should be operated below the absolute maximum electrical ratings specified in the manufacturer's data sheet in order to safeguard their reliability and service life, as well as to ensure that the LED is operated safely. One factor that contributes to LED failure in LED circuits and systems is electrical overstress (EOS). This application note describes the nature of EOS, explains how it differs from electrostatic discharge (ESD), discusses its causes, outlines EOS-related damage and provides information on how an LED can be protected from EOS.

Thermal Management of Light Sources Based on SMD LEDs is an introduction to the basic principles of heat transfer and its influence on LED applications using thermal management at different system levels.  Relevant characteristics are described and discussed in this application note.
For more helpful application notes on LEDs, please visit our Applications Notes webpage where you can find application notes on topics such as ESD Protection while handling LEDs, Comparison of LED circuits and Ambient Light Sensors - General App Note. Product and application specific notes come in handy when you have selected an LED for your project, such as Thermal Management of Golden DRAGON LED and Street lighting with LED sources.

Making Headlights Even More Intelligent

 

 

 

 

Advanced Forward Lighting Systems (AFS) that adapt their illumination direction when driving thru curving roads and other scenarios, can now be even more easily implemented by automobile manufacturers. OSRAM Opto Semiconductors has developed a new OSRAM OSTAR Headlamp Pro that offers, for the first time, a specific LED component for this particular application. The five chips of this new LED can be individually controlled and flexibly switched on and off according to driving situations and the positions of other vehicles on the road.
