A STUDY ON HIGH EFFICIENT AND ENERGY SAVING LIGHTING SYSTEM FOR JIUZI ANCIENT TOWN IN CHINA (PP06, 265-270)

According to the statistic published by Chinese National Tourism Bureau, during the holiday from 1st October to 7th October 2017, the number of tourists who travelled in the mainland China reaches 663 millions, and it has 11.96 % jump if compared to last year, and the total income reaches RMB 549 billions!

The night landscape lighting in Jiuzi Ancient town not only serves aesthetic value, economical value and environmental value on tourism, but also creates a primitive and quiet atmosphere at night and a perfect harmonization with the historical architecture. The key issues of this study work are the appropriate luminance distribution, luminance contrast, the smart use of colour to meet the aesthetics need of old ancient town, integrated application of LED lighting science and technology, creating comfortable and peace illuminated environment of old architectures, applying green lighting and controlling light pollution.
