Description of the Plan：

　　Measure the illumination quality of LED lamps deployed along the expressway in order to analyze the characteristics and the energy conservation and carbon reduction effect of these lamps for using as the reference by MOEA and competent highway administration agencies.

Research result：

• After comparing the measured LED lamps and the existing high-voltage sodium lamp, the result indicated that some 40%~55% of power can be saved. Based on the cost-efficiency analysis result, some 40,000 KWH can be saved by 68 units of LED lamps per year.   
• Solve the problem where the prevailing CNS15233 standard cannot be applied in the freeway and freeway systems, enhance the illumination efficiency of LEC lamps, include the chromatic standard, use low color temperature and add the water and dust resistant performance, etc. for use by MOEA in developing the “Freeway & Expressway LED Lamp Standard (Draft)”.
• The research result shall provide the measuring data required for the photoelectric industry in Taiwan to help improve the product design in order to meet the demand of freeway/expressway and shorten the gap with major international plants.

Effect of the plan：

　　Analyze the efficiency of LED lamps for the competent highway authority and MOEA in developing statutory rules. In the meantime, the research result can also help the photoelectric industry to improve the product design.Note: MOEA has used the research result of chromatic change (du 'v') as reference for developing relevant standard.
