3 distribution photometer type 4
Lsg-5000 is a 3D system that can automatically test the light intensity distribution curve
The test distance is required to be 5 to 30 meters, which can meet the test requirements of various light sources, such as LED light source, HID light source, indoor and outdoor lighting, street lamp, floodlight and other lighting lamps

 
Measurement parameters: ,
Light intensity, light intensity distribution, regional luminous flux, luminous efficiency, brightness distribution, utilization coefficient, brightness limit curve, glare level, maximum allowable distance to height ratio, isoilluminance diagram, upper luminous flux, lower luminous flux, isoilluminance curve, isointensity curve, effective luminous angle, EEI, UGR, etc

Product features:
• The near-field probe and reflector will make circular motion around the lamp, and the far-field probe and reflector will rotate synchronously
• The ignition point of the lamp remains absolutely static, and the probe will always sense the light source of the lamp
• The drive motor adopts Japanese Mitsubishi servo motor and German * to ensure high-precision and stable operation, and the start and stop are very stable
• The test principle meets IESNA and CIE standards, and fully complies with lm-80, lm-79-19, lm-75, GB / T 24824, en13032-1, cie121 and other standards

• A special cross laser calibration device is configured to fix the position of the measured light source conveniently and accurately

Technical parameters:
• Range of reflector or moving probe around the lamp under test: (& gamma;)& plusmn; 180° (or 0~360°)
• Angle accuracy: 0
05 & deg;, Angular resolution: 0
001 & deg;
• Probe accuracy: class L constant temperature probe din5032-6 / CIE pub1 No
69（LSG-5000）
• The test results can be saved as CIE, ies, LDT or other format files, which can be directly imported into relevant lighting design software, such as Dialux
• Communicate with the computer through RS-485 / USB interface, and the English test software can run on win7, win8 or win10

• Lsg-5000 can work simultaneously with a high-precision CCD spectroradiometer to test spatial correlation color temperature distribution and other spatial spectral color distribution
We call it spatial spectral radiometer
Lsg-5000ccd spatial spectral radiation vertical distribution photometer = lsg-5000 lm-79 vertical distribution photometer system + lpce-2 high precision fast spectral radiometer & amp; Integrating sphere test system
