between.
For a planar light source, 4 types are often better than 006 if there is only a low-brightness framing wing light distribution luminaire, as calculated by Aos class, UGR=18. The latter is more realistic, the calculation result for the semi-specular reflector system , will be between the above two, take the average value of 008 and Lnst. The symbols used in this section are as follows: meaning: the projected area of ​​the light source in the direction of the eye 2A.: the projected area of ​​the light source toward the lowest point 2丫: From the lowest point to the angle of the eye; "From the lowest point to the maximum light intensity; 1: Light source intensity in the eye" 11: Maximum light intensity of the light source Brightness of the light source / Mountain background brightness 1/12 solid angle position coefficient of the light source; Light source to Wang Zuo The distance from the light source to the eye is 1.
The first optical fiber and light pipe application technology seminar in the field of lighting was held. The first optical fiber and light pipe application technology seminar in the field of lighting was planned and hosted by the China Lighting Society from October 31 to November 2, 2000 in Beijing. Representatives from all over the country attended the seminar, including representatives from the United States, Japan, Singapore and Taiwan. The sponsors and main co-organizers of this seminar are Philips Lighting China Lighting Division and Shanghai Lighting Institute. The co-organizer is Japan Co-Prosperity Co., Ltd. Nanjing Glass Fiber Research and Design Institute and Suzhou Yide Technology Development Co., Ltd., they gave strong support from the initiation, planning and co-organizers.
The conference received 21 papers written by various parties and was compiled into a book. It involved many aspects such as light application, light technology research and development, and light pipe research and application. This is the first collection of technical data in this field in China. The detailed and rich content covers all aspects, basic knowledge and basic theory. Application Design. Use examples. The development history and other aspects are all available, and it is a rare and good information for readers involved in this field.
The conference exchanged more than ten papers. The authors have learned from various aspects the ambiguity, experience and achievements in this aspect of work, giving the delegates a lot of rewards and gains.
Fiber optics and light pipes are new equipment in the field of decorative lighting in China. At present, there is a lack of information, materials and equipment. Through this meeting, delegates have benefited a lot, mainly reflected in the following aspects: 1. Understanding the main products of this product in China The production companies are as follows: Philips j. Co-Prosperity Co., Ltd., the domestic enterprise is Nanjing Chunhui. Nanning Jinming. Guangdong Zhen Mingli, Guangzhou Guangsheng. There is also Swarovski in Austria, which is engaged in the lens trade.
2 The number of optical fiber application projects in China is constantly expanding. There are more than ten examples in Beijing.
Classification of optical fibers. Basic knowledge such as performance, easy to develop and apply. The representatives of the city are very interested in the light pipes brought by the 3 companies, and they are eye-opening.
The conference was very successful, and the exchange of information established a relationship. In particular, the introduction of the Nanjing Museum attracted the interest of the participants. From the user's point of view, it was a clever use of the optical fiber application of the Society and the current booming museum business. The introduction was made and a good suggestion was made.
We believe that with this first exchange of learning, there will be a second time, which will eventually push the development, research, production and application of this field in China to a higher level.
