Presently, the biggest problem of Chinese LED lighting industry is the deficiency of national standards and industry standards. The disorderly market is full of enterprises with uneven capacity and products with inferior quality, which blows the market confidence. The semiconductor lighting standards are expected by many persons in the industry. Nine Chinese official-led industrial standards were approved by Chinese Ministry of Industry and Information Technology and were fully implemented on January 1st, 2010. The standards include: Semiconductor Optoelectronic Devices -- Blank Detail Specification for Power Light Emitting Diodes, Test Methods of Semiconductor Light Emitting Diodes, Sapphire Substrates for GaN-based Light-emitting Diode, Phosphors for Light Emitting Diodes, Technical Specification for Power Semiconductor Light-emitting Diode Chips, Test Methods of Semiconductor Light Emitting Diode Chips, Semiconductor Optoelectronic Devices -- Blank Detail Specification for Lower-power Light-emitting Diodes and Series Program for Semiconductor Light Emitting Diodes, etc.

The nine standards cover LED materials, chips, devices and relative test methods. Among them, the Sapphire Substrates for GaN-based Light-emitting Diode specifies the parameter indicators, test method, physical dimension, experimental method and quality guarantee provision, etc of sapphire substrates for GaN-based lighting-emitting diodes. The Phosphors for Light Emitting Diodes stipulates the performance requirements, experimental method, testing rules, mark, package, transportation and stock, etc of phosphors for white LED; the standard also includes 5 marks of aluminate phosphor and 7 marks of silicate phosphor. As the technology and production of the new nitride phosphor need further improvement, it is excluded from the standard.
