Green energy industry of MOEA
White light LED policy
Although the LED industry in Taiwan flourish in recent years , but it still lacks for
standards and standardized tests for the application until 2007.
With MOEA green energy industry policy, DoIT promotes the development of LED
lighting, LED light source to enhance the efficiency and reliability, and speed up
the establishment of industry standards and standardized tests
