Light has long symbolized human inspiration, imagination, and fantasy. In modern days, it is a key driving force behind information technology and it is literally lighting the way to green energy revolution. The International Year of Light and Light-based Technologies (IYL 2015) presents a unique opportunity to inspire, educate, and connect on a global scale. The promotion of key ideas and the corresponding outreach activities for IYL 2015 was well received by the many organizations and institutes in Taiwan, which include (but not limited to) the Physical Society (PSROC), the Center of Advancement for Science Education (CASE) of National Taiwan University, the Interdisciplinary Science Education Center of National Tsing-Hwa University, the Taiwan Photonics Society, National Synchrotron Radiation Research Center (NSRRC), Photonics Industry and Technology Development Association (PIDA), Taipei Astronomical Museum, etc. Riding on the wave of IYL 2015, many activities and events are planned in a laissez-faire style with some popular themes commonly found in Taiwan’s night market.
In Asia, an innovative ancient Chinese philosopher, Mozi (470 BC – 391 BC)  provided the first documentation on the working principles of light. In his work (which was also named “Mozi”, after himself), he gave a detailed description on geometrical optics. Celebration of light through the Lantern Festival  in Chinese Society dated back to 200 BC. The festival is held on the 15th day of the first month in the lunisolar year of the Chinese lunar calendar, and it marks the last day of the Lunar New Year celebration. The latter celebration is usually held in February or March in the Gregorian calendar.
The Lantern Festival has been a festival of great significance as early as the Western Han Dynasty (206 BC-AD 25). The festival is symbolized with imaginative colorful lanterns embossed with intriguing lantern puzzles and riddles. Delicious glutinous rice balls named after the festival yuanxiao itself (and also known as tangyuan (湯圓)) are well received by both adults and children. This unique combination of activities in the traditional Lantern Festival provides a very creative, intellectual, and enjoyable atmosphere. In Taiwan, the festival has attracted more than 8 million visitors annually in the last few years.
Taking advantage of the festival, the PSROC has championed IYL 2015 by promoting popular science through outreach activities at the Lantern Festival, held during 5-15 March 2015 in Wuri, near Taichung High Speed Train Station. The outreach activities were organized by the Interdisciplinary Science Education Center of National Tsing-Hwa University and led by Prof. Ming-Fong Tai, together with many teams from various universities . Many Do-It-Yourself (DIY) kits  were presented to elucidate the working principles of optics and physics in general. These kits included: floating image,colored shadow, chromadepth 3D glasses, joule thief, perpetual spinning top, magical polarizer, magic piggy bank, amazing T-rex illusion, Pepper’s ghost and many more. These kits allowed the audience to understand optics and physics through hands-on personal experiences thus making the pop-science activities in the festival a huge overwhelming success. Many participants repeatedly came back with their families and friends to imbibe in the excitement of scientific discovery and understanding. The physics education community was so impressed with the results that they decided to continue this outreach event at future Lantern Festivals. 
Many other additional events and activities for IYL 2015 have been organized. A partial list is given below:
- The Center of Advancement for Science Education (CASE) of National Taiwan University organized “The Journey of Light”, with generous support from Taiwan Semiconductor Manufacturing Co. Apart from lectures by established scholars, the event focuses on the pop-science presentation contests for K9-K12 students. 
- On the last day of 2014, the newly constructed Taiwan Photon Source (TPS) of National Synchrotron Radiation Research Center (NSRRC) delivered its first synchrotron light at 13:58. The electron beam energy of the TPS circulating in the storage ring reached the designated value of 3 GeV, and the stored beam current achieved over 1 mA, marking a significant milestone for the Taiwan’s new synchrotron light source. 
- The Photonics Industry and Technology Development Association (PIDA) has been championing photonics technologies for more than 20 years. The Photonics Festival in Taiwan (PFT) this year is organized by PIDA from June 16 to June 18, 2015 and it showcased the best of Taiwan photonics industry with the latest products and technologies, focusing on 3D printing, biophotonics, and plant factory. 
- The Taiwan Photonics Society organized monthly lecture series at the universities to address various photonics researches and also contributed a large lantern for the Lantern Festival. 
- Riding on their success in organizing the Year of Astronomy 2009, the Taipei Astronomical Museum (TAM) organized an event with the theme: “Mystery light, exploring universe and improving life (探索-光的奧秘)”. The event attracted many school children across the whole of Taiwan.
