Product description and applicable:
The HP880 light intensity distribution tester is used to test the light distribution curve, light intensity data, beam angle, and equivalent luminous flux of small lamps such as LED spotlights and semiconductor light-emitting devices.
The instrument comes with a three-jaw chuck and is equipped with a cross-shaped clamp, which is convenient for installing lamps and light-emitting devices, and is cost-effective.
Main technical features:
1. The test method meets CIE and international requirements
2. The photoelectric detector has a high correction level and meets the National Class-1.
3. Automatically draw light intensity spatial distribution curve (polar coordinates and rectangular coordinates)
4. The measurement data complies with international and domestic requirements, is output in IESNA file format, and can be directly called by other lighting and lamp design software
Main Specifications:

Rich software features:
1. Control the rotation of the rotary table, collect the light intensity distribution data of the lamp, and calculate the photometric data of the lamp and the conversion of the coordinate system;
2. Including spatial light intensity distribution, spatial color distribution, light intensity distribution curve on any cross-section (can be displayed in rectangular coordinate system or polar coordinate system respectively), spatial equal light intensity curve, plane equal illumination distribution curve, brightness limit curve, Ring luminous flux, glare level, lamp efficiency, effective luminous angle, upward luminous flux ratio, downward luminous flux ratio, total luminous flux of the lamp, and effective luminous flux.
3. Export lamp files that comply with international standards and can be directly imported into lighting design software. The format description is as follows:
*.HPG iridescent photochromatic HPG series goniophotometer test data file format;
*.IES IESNA North American standard format, including version 95 and 2002;
*.LDT EULUMDAT German Standard (European) Qualification Examination Document;
*.CIE CIE International Commission on Illumination standard format;
4. According to the type of lamp under test, such as street lamps, outdoor lamps, indoor lamps or floodlights, etc., the corresponding printed report can be output and can be directly saved as a PDF file.
