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
