China's Ministry of Industry and Information Technology Standards Working Group of semiconductor lighting technology since its inception in 2005, according to market and industry development, actively carry out technical standards for semiconductor lighting industrial system of the formulation. The group said it had lighting materials in the semiconductor, chip technology, packaging, product testing and test methods have achieved a breakthrough.
Among them, led by the Chinese government, "Semiconductor optoelectronic devices for the power light emitting diodes Blank detail specification", "The semiconductor light-emitting diode testing methods", "GaN-based light-emitting diode chip with a sapphire substrate," "light-emitting semiconductor polar body fluorescent powder, "" power semiconductor light-emitting diode chip technology specifications, "" light-emitting diode semiconductor chip testing method "," Semiconductor optoelectronic devices for low-power light emitting diodes Blank detail specification "and" The semiconductor light emitting Product series model of polar body "and nine industry standards have been approved by the Ministry of Industry and Information Technology released and will be January 1, 2010 into effect.
9 to be implemented include the industry standard LED materials, chips, devices and related areas such as inspection and testing methods, including "GaN-based light-emitting diode chip with a sapphire substrate," the provisions of the GaN-based light-emitting diodes with a sapphire liner the parameters of the film index, test methods, geometry, test methods, quality assurance requirements, etc., "The semiconductor light-emitting diodes using phosphors," provides white light emitting diode with phosphor performance requirements, test methods, inspection rules and signs, packaging, transportation, storage, etc., the standard includes five grades aluminate phosphor and silicate phosphors seven grades, for the present relatively new nitride phosphors, taking into account its technical and production there will be a great improvement, not yet included.
The implementation of the specification standard semiconductor lighting industry market, improve the existing system, motivate and encourage trans-regional free enterprise competition advanced to promote the technological innovation of great significance, is also conducive to industry and market order.
