German professional authority magazine reports the latest results of the distribution of distant companies

The German light and lighting professional authoritative academic journal "LITCH" (light) in 2009 the 11-12 published a paper in China luminosity distribution principle of the latest achievements of the whole space GO-R5000 meter rapid distribution photometer, and the German Institute of physics and Technology (PTB) Robot goniophotometers working principle on the same page, for this China light product There was no parallel in history..

Distribution photometer is an important instrument to evaluate the light source and lighting space light distribution performance, because of the combination of optical, mechanical, electronic, software, automatic control and other disciplines, has always been regarded as one of the most advanced equipment in the field of optical radiation measurement. Germany has occupied the dominant position in the world.

With the recent development of LED new light source, the German PTB Robot developed a new generation of the luminosity distribution (robot distribution photometer), as shown in Figure 1 and Figure 2, the distribution photometer has a system with three arms, each arm seven can be measured by the control shaft. Light source and detector positioning suspension. Robot distribution photometer is considered to have high accuracy, but it is bulky and expensive.

Hangzhou everfine Photoelectric Information Co. Ltd. (hereinafter referred to as the "distance") is China's light industry leader, as early as 1997 began to enter the goniophotometers research and manufacture field, after the development for more than ten years, the company not only on the distance distribution of luminosity development of the world's most complete series of products, but also from the introduction digest began to create independent enter. GO-R5000 full space distribution photometer is far away in the 863 international project support, based on the circular motion of the mirror type distribution photometer, a new generation of luminosity distribution created independently, while the application is in the United States and Germany national patent.

The working principle of the GO-R5000 spatial distribution photometer is shown in Figure 1 and figure 3, real as shown in Figure 4, can realize the far field measurement: beam light source to be measured or lamps are reflected rotating mirror and the fixed mirror is far field detector; near field measurement: covered by black light the two sides mirror, near field probe for direct measurement of beam light source to be measured or lamps, the near field probe and matching photometric probe, spectral radiometer, imaging luminance meter and a variety of different types of detectors; intermediate field measurement (option): intermediate field detector phase switching and fixed mirror receives the measured light or lamp and a light beam passing through the rotating mirror reflection. The space distribution photometer by flexible configuration, can be set in one of the 6 functions, and control system through innovation, system has a high angular accuracy and measuring speed, can realize the benchmark level total luminous flux measurement of various light sources and lamps, accurate measurement of spatial intensity distribution and spatial distribution of color and brightness distribution etc.. The technical indicators in the international leading position.

In fact, the wide range of the company's rapid distribution of the wide range of photometer once launched with its superior performance and excellent price performance to attract the world's vision of the metering sector. In 2007, the International Commission on illumination (CIE) conference exhibition, is Everfount received including Fudan University, Taiwan ITRI, British Cooper, GE and other domestic and foreign research institutions and enterprises quality inspection orders. In 2009, the company was invited to be in the CIE (International Lighting Committee) in the interim meeting of the introduction of the full space distribution photometer, once again won the world wide attention and recognition. Therefore, it has been mentioned at the beginning of the story, the world goniophotometers experts, one of the founders of LMT, a German professor Dr. Max Peter at Berlin University in Germany for the German optical journals "LITCH" the author introduced the world advanced meter luminosity distribution products, analyzes the design principle of excellent distance GO-R5000 deep into one, and give the fully affirmed and highly praised.

The high-end metering equipment with independent intellectual property rights of our country has already won the recognition and respect, and gradually enter the international high-end market, the China Light Industry and the equipment manufacturing industry is worth the dance for joy.
