How to Read a Datasheet Part 1 of 2: Typical/Maximum Characteristics & Binning-LED Fundamentals

972 views

Published on

OSRAM Opto Semiconductors presents How to Read a Datasheet Part 1 of 2 - Typical/Maximum Characteristics and Binning as part of the LED Fundamentals section on the LED Light Site. In this presentation we examine the key parameters specified on the first half of an LED datasheet from OSRAM Opto Semiconductors. The datasheet captures some of the most important technical characteristics of an LED. These include electrical, optical and thermal quantities, knowledge of which is paramount for an LED system design. Also, it has information on ordering codes, labeling and packaging of the LEDs.

  2. 2. LED Parameters Optical Quantities  Luminous Intensity IV  Luminous Flux FV  Radiation Characteristics  Viewing Angle 2φ  Dominant Wavelength ldom  Color Coordinates cx, cy Thermal Quantities  Junction Temperature Tj  Temperature Coefficient TC ldom  Thermal Resistance RthJS Electrical Quantities  Forward Voltage VF  Forward Current IF  Reverse Current IR Misc  Color Rendering Index - CRI  Efficacy
  3. 3. OSLON Square (GW CSSRM1)
  4. 4. Ordering Information  Luminous Flux at binning current is listed in lumens (lm) or millilumens (mlm).  Color Temperature is listed in Kelvin (K).  Example GW CSSRM1.EC-MQMS-5L7N-1  MQMS: One brightness bin MQ, MR, or MS will be shipped for any one reel.  5L7N: One chromaticity bin from 5L7N will be shipped for any one reel.  1: One forward voltage bin will be shipped for any one reel.
  5. 5. Maximum Ratings
  6. 6. Typical Characteristics
  7. 7. Brightness and Forward Voltage Groups
  8. 8. Chromaticity Coordinates ANSI Quadrangles
  9. 9. Color Chromaticity Groups
  10. 10. Group Name on Label
  11. 11. Spectral Emission Vl is the human eye sensitivity curve
  12. 12. Radiation Characteristics  For OSLON Square (GW CSSRM1) the radiation curve hits the 50% line at (φ )60°  Therefore the viewing angle (2 φ) is here equivalent 120°
  13. 13. LA CPDP Peak wavelength Wavelength with the highest emitted electromagnetic power Dominant wavelength Wavelength considering human eye sensitivity; defines the color we can see
