The present invention provides an algae culture device, in particular, a light source unit can be completely and completely coated on the outer periphery of a transparent culture unit to provide photosynthesis 24 hours a day, and the algae can be cultured quickly and in large quantities, and the algae can be cultured. When the aquaculture is completed, the culture unit is taken out and harvested, and the new culture unit is replaced and the algae are continuously cultured.本創作係提供一種藻類養殖裝置，尤指一種光源單元可全面完整的包覆在透明養殖單元的外周，以提供全天候24小時進行光合作用，而可快速且大量地養殖藻類，並藉由該藻類養殖完成在採收時係將養殖單元取出處理，而更換置入新的養殖單元，繼續養殖藻類。
