About This Product

Measures the total luminous flux of lighting sources such as LED lighting, LED backlights, and organic EL with simple operation and high accuracy.

■Summary

The total luminous flux measurement system can measure light sources with 2π and 4π light distributions that comply with LM-78 and LM-79 established by the LED lighting measurement standard IESNA (Illuminating Engineers of North America). In addition, as a calibration function, self-absorption correction and spectral sensitivity calibration are possible using a measurement method compliant with JIS C8152.

■Features

- Selectable integrating sphere size (from 2 inches to 3m (120 inches)) ・Enables long-term stable measurement due to the highly weather-resistant material on the inner surface of the integrating sphere. ・Light source measurement up to 100,000lm possible ・Satellite type integrating sphere can be installed in the measurement port ・Detector can be selected from highly sensitive cooled BT-CCD and high D range type NMOS ・Support jigs and sockets available for various light sources ・Standard LED compatible holder can be installed ・Measure the total luminous flux by automatically controlling the light source lighting power supply, wattmeter, and spectrometer ・Equipped with self-absorption correction function using self-absorption lamp ・Equipped with wavelength axis calibration function and spectral sensitivity calibration function ・Dedicated software in Japanese, English, and Chinese versions is included as standard.

■Basic configuration

・Integrating sphere ・Spectrometry device ・NIST compliant calibration light source ・Self-absorption correction lamp ・Low pressure mercury lamp ・DC power supply (AC power supply or wattmeter if necessary) ・Dedicated software

■Configuration diagram

Depending on the light distribution characteristics of the measurement light source, it can be divided into 2π measurement and 4π measurement. Light sources that emit light in all directions, such as incandescent light bulbs, are measured by 4π and are placed at the center of the integrating sphere. Light sources that emit light in the forward direction, such as spot lights, are measured by 2π and placed outside the sphere. Take measurements.

■Anytime measurement function

It is effective for production purposes by measuring multiple sample light sources at any time and centrally managing the measurement results.

■Time measurement function

It is possible to measure over time to centrally manage the lighting status for quality control and research purposes.
