Pan Jiangen, Technical Director of Hangzhou Yuanfang Optoelectronic Information Co., Ltd., gave a report titled "Full Space Distribution Photometric Measurement Technology for LEDs and LED Lamps" in the "International SSL Standards and Testing Lecture" held on October 14, 2009. He is in the report. It is pointed out that the emerging light source of LED is very different from traditional light source in optical characteristics, luminaire design and lighting application. The spatial light intensity distribution measured under long distance is not enough to fully characterize the spatial luminosity characteristics of LED or LED luminaire. This poses challenges for the development and application of LED and LED luminaires. With the rapid development of photometric technology in recent years, the full spatial distribution photometric measurement of light sources and lamps has become possible. It can provide brightness distribution, light intensity distribution and illuminance distribution of arbitrary cross sections in all directions for LEDs and LED lamps. Detailed spatial light metrics.
Pan Jiangen believes that with the in-depth development of semiconductor lighting, the requirements for comprehensive and objective characterization of LEDs and LED luminaires are becoming higher and higher. The development of full-space distributed photometric measurement technology has succeeded in providing solutions to these problems. Full-space photometry can model realistic light sources. Users can intuitively and accurately obtain the light distribution of the light source or luminaire. The illuminance distribution in any section (plane or surface) of the whole space, the far-field intensity distribution and the difference Observe the important parameters such as the brightness distribution of the light source or the luminaire. These quantities are not achievable by traditional photometric measurements. Full-space photometric technology is bound to play an increasingly important role, revolutionizing the measurement of light sources and optical design.
Pan Jiangen also said that with the support of the National 863 Project, China has taken the lead in successfully developing a full-space distributed photometer system with core independent intellectual property rights, and relying on technological advantages, the development unit of the full-space distribution photometer Hangzhou Yuanfang Optoelectronic Information Co., Ltd. Participated in the development of CIE related standards. At present, the full-space distribution photometer has been used by many LED luminaire measurement laboratories and large-scale manufacturers at home and abroad, and has won unanimous praise.
