DFA亞洲最具影響力設計獎 2019 l 大獎優異作品
Lumir K 是一款由食用油驅動的LED燈，以用過或新鮮的油為燃料。它不需依靠外來電源，亦不受天氣影響，主要為生活缺乏電力供應的人而設。它的原理是「賽貝克效應」，利用兩種不同的電子半導體之間的溫差產生電壓差，將熱能轉化成電能啟動LED燈。使用時將油倒入裝有燈芯的小罐中，燈芯燃起後令感應器加熱繼而開啟電燈。
五毫升的食用油便足以令Lumir K亮起一個小時，因此能節省多達80％的燃料成本。同時它亦減低黑碳的耗用。跟煤油燈相比，它二氧化碳及一氧化碳的排放量分別低92.8%及85%。Lumir K的光度比煤油燈亮四倍，而且容易開啟，只需把燈放在點燃的燈芯上便可使用。它價格相宜、安全、明亮、便於攜帶又高效能，估計可以使用10年。
