Product description and application:
HPG2000 is a C-type goniophotometer, a moving mirror goniophotometer recommended by the American national standard NSI/IESLM-79-2019. The reflector that moves in a circle around the center of the test lamp reflects the light beam in the measurement direction of the lamp onto the photometric detector, thereby achieving the measurement of light intensity distribution curves on different planes. This system complies with the American Energy Star IESLM79 standard, European standard EN13032GB/T9468 and other relevant international and domestic standards.
Main technical features:
1. The measurement position of the lamp under test is consistent with the actual use state, and the working state of the lamp remains unchanged;
2. The reflector can rotate 360 degrees around the lamp under test, and the lamp under test itself can rotate 360 degrees;
3. Adopt precious metal optical fiber spot brush technology to achieve uninterrupted continuous measurement without winding and stable rotation;
4. Laser crosshair aiming device, convenient and accurate installation of the position of the test lamp;
5. Highly stable probe holder with light-shielding grating, adjustable height, adjustable up and down and left and right tilt angles;
Main Specifications:
1. High-precision constant temperature probe (constant temperature point 35±1 degrees, constant temperature accuracy ±0.1 degrees);
2.V(λ) correction accuracy: CIE standard level (f1’ <0.03);
3. Illuminance measurement range: 0.001 lx to 200 klx, 5-speed automatic range;
4. Photometric probe connection cable length: 20 meters (can be lengthened for special requirements);
5. Angle accuracy: 0.1 degrees, angular resolution: 0.01 degrees;
6. Maximum size of equipment: length, width and height 2400×3200×3300mm, center height 1600mm;
7. Minimum size of darkroom: length, width and height 12m×3.5m×3.5m;
8. Maximum size of lamps: Maximum light outlet size <1.2 meters, square lamp: 800mm×800mm, strip lamp: 1200mm;
9. Prepare a variety of test fixtures: street light fixtures, panel light fixtures, long fluorescent lamp fixtures, and E40/E27 lamp holder fixtures;

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, 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, annular luminous flux, Glare level, lamp efficiency, effective luminous angle, upward luminous flux ratio, downward luminous flux ratio, total luminous flux of the lamp, effective luminous flux, and utilization coefficient.
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, which can be directly saved as a PDF file, etc.
