Package LED (OPI-305 Goniophotometer)

Luminous
Sugwangbu

Easy measurement for directional angle and luminous intensity for various LED

  • One touch Method
  • Luminous intensity and added directional angle measurement function
  • Adapter(Socket assembly) for various LED/OLED
  • Range for measurement angle and step angle and average time are selectable
  • Gap angle (directional angle) for desired position is calculated (Example, 75%, 50%, 25%)
  • Measurement within 30 seconds; shortening time depending on area and set up condition
  • Multiple measurement for several samples by z-axis angle
  • Built-in power supplier for LED (0~200mA), and additional power supplier is also available

Accuracy and reliability of measurement results

  • Measurement mode of CIE (Commission Internationale de l'Eclairage;)
  • Correction by certified specimen from Korea Research Institute of Standards and Science
  • Accurate light discharging and intensity of illumination (less than 0.1 degree in angle resolving power: option)
  • 2-dimensional measurement (left-right) and 3-dimensional measurement of light discharging
    by rotating luminous axis using step motor
  • Measurement of angle up to +135~ -135 (360 of rotation is mechanically possible)
  • Maximum rotation angle for luminous axis is 360 degree.
  • Excellent position accuracy and repeatability, and low noise, rapid measurement
  • It's possible to measure High Power LED by equipping with temperature controller (Medium-sized gonio specification)

Compatibility with other equipment and extended measurement items

  • It is able to measure optical and electrical characteristics depending in LED emis-sion angle
    by connecting with LEOS(Spectrometer)
    -Optical characteristics : Wp, Wd, Iv, Ie, Cx, Cy, FWHM, CCT, CRI, Optical Efficacy
    -Electrical characteristics : Ir, Vr, If, Vf, L-I-V Sweep Curve
  • other integrating sphere system-connected measurement items : ØV, Øe
  • Its sensor parts can be equipped with various meters
    [Spectral and radiation meter, brightness meter and luminous intensity meter (Option)]

Easy measurement result edition and usability

  • Text and graph-typed measurement result, filtering and editing of measured date
  • Storing measurement results to Excel(*,CSV), Text and picture file (BMP), and support for IES format.
  • Various reporting formats - Deleting/Adding a specific measurement date
  • Luminous distribution can be expressed by 2, 3-dimensional graphs and data lists by analyzing, summarizing and overlaying measured date

Measurement result - Text 2, 3-dimensional luminous distribution
