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

California Forbids to use the incandescent lamp before 2012

England Plan to eliminate incandescent lamp gradually before 2012

Policy –1.LED Lighting will be the new trillion industry in the near future

2015 (2008.12.30 announced).Promotion –

1.2W AC LED installed at Village Simakusi in April, 2008.2.Promoted 「The LED street light demonstration project」 at

locations across the island since 2008.


LED Lighting Demonstration I :2W AC LED Installed at Village Simakusi

The last village in Taiwan to be connected to the national electricity grid.

Become the first one to turn on LED energy saving lights.

(2008.04.01)


LED Lighting Demonstration II: LED Street and Garden Lamps at Taipei

(2008.12.19)

• The first demonstration construction in Taiwan to test and verify the LED systems with CNS standards at 3 locations of Taipei.

• Conducting a lighting ceremony at 228 memorial park
