LED standards should be how to use?

LED on how to use the standard, there are many questions. The international standard OLED project leader, LED backlight, light radiation group members, international standard safety expert at the Zhejiang University of optoelectronic information engineering department associate professor Mou Tongsheng; Tsinghua University Shenzhen Graduate School of Physical Electronics and laser devices, associate professor; Tsinghua University Shenzhen Graduate School of semiconductor lighting laboratory deputy director Qian Keyuan and other speakers do a detailed answer.

Question: Hello, I would like to ask, teacher, I made a project recently discovered a problem, he put in the pool with LED lights, I saw the IEC standard, ICE60598 has a swimming pool, but it is 1993, not back he updated, there is a standard 12 volt standard, before LED, IEC is there a process, how do they review the inside of the standard, to include the application of LED, is there a timetable? How will the standard update?

Mou Tongsheng: you just mentioned the problem very timely, in fact for our lamps and lamp standards, chairman of our committee to talk together in a week ago, after the street standards do, he also had many views, in fact we are doing LED of the street, he said that our the lamp itself has a standard, do not use the original standard, if people do not write standard so many expertise will leak. According to the safety standards of the original, our country is 7000.1GB, IEC60598 is the special requirements of LED lamp, equivalent to IEC60598 or GB7000.1, such as the safety standard of a single light LED, including some voltage requirements. Now in the IEC not mentioned in this matter, we believe that the National Standardization Committee will soon do the project you have talked about the problem. Peng Zhenjian: I add that gentleman to the first question is lighting the swimming pool, I think is not too deep, the lamp pool on the long-term water standard for your lamp is based on three kinds of lamps, avoid your lamp with the waterproof problems caused by the swimming the pool are charged, the lighting in the underwater work, requirements of lighting design in special safety voltage under voltage, the lamp has a standard voltage, and there is no necessary link source you use, just, the teacher also said that the National Standardization Technical Committee sub committee will discuss the LED lighting problem, like you just LED said, this created a professional, revised some of the standard of LED lamps, now I understand it, IEC60598 in the 2005 version have we describe is not classified, divided Class as a simple term, previously classified as tungsten filament lamp, fluorescent lamp and gas discharge lamp classification, and now there is no such classification, a simple electric light source contains. From the change of model can be said to the standard of IEC 60598 from the overall safety standards there is not too much to consider what the source, we are now encountering a problem, our traditional lighting standards will have a relatively large difference is the source of this part of the understanding. The traditional lamp is not with light, but it is for the design of light source, we now put the whole lot of LED lamps LED components and drive module, combined into a complete, there can be some understanding, understanding of the standard, standard methods and measures to bring some traditional lamps have something different understand.

Station in my own point of view, like some properties, like some mild indeed as supplementary requirements, as most of our products, from the safety test, cell compatibility test two, basically no time also called LED lamps or traditional lamps, this is me point of view. Like some performance tests, we used in LED, or go back to the problem, or the light source, we can evaluate the signs such as incandescent light bulb performance, it is independent of the standard, the fluorescent lamp also has a separate standard, but LED is used in the specific products, we will combine the product. Evaluation of its performance parameters, including the thermal performance and color performance, if we have a day, now some of the LED alone as a substitute, the lamp is a lamp, the light source is a light source, the integration should consider together 2. IEC is not very clear about this.

Question: Hello everyone! I am from OSRAM LED department, have a question to ask the teacher when the money, in the interpretation of Guangdong Street standard, there is a reference, a grade 78lm/w, two grade 68lm/w, this value is very accurate, I think from the engineering point of view, when you make this standard is how to consider, after which to compute such accurate value?

Yuan of money: you said the accurate calculation, the calculation can't calculate, because LED people are not the same, OSRAM and Taiwan chip, Hongkong chip light utility is not the same. According to the technology can now be done at the time, we feel that we can do is the level of technology, this standard does not come out of you tomorrow, I am more than, this is the first consideration. The second point is the countries are similar in the formulation of the draft standards, local standards must refer to the relevant national standards in the specified time, then that is even lower than the national standard, the low word has no meaning. At that time, the country also has some reference value, we are still a little higher than the reference value, it is so out of.
