Abstract: A novel LED fishing/working light is proposed for enhancing the lighting efficiency of a fishing boat. The study is focused on the freeform secondary lens design for creating a lamp to attract fishes and shine light on the deck for fishing work. The experimental results show that the proposed multi-segmented freeform lens (MSFL) can accomplish the proposed light three times illuminance more than that of the traditional HID fishing lamp under the same input electrical power.
