An air-flow type air-cooled lamp group includes a lamp holder, a light source, a heat dissipation fin, and a heat dissipation unit. The heat dissipation unit includes a fanless fan and has a gas output channel, and at least one air blowing motor is arranged in the The fan blade fan is equipped with a control valve at the connection between the gas output channel and the air supply motor, which can enable the air-cooled lamp group to achieve multi-stage and large air volume operation, and can extend the service life. Among them, an upper cover is arranged on the lamp holder, The junction is also equipped with a waterproof rubber ring, which can prevent seawater and air from eroding and damaging the lamp set. In addition, users can achieve more than two airflow gains by installing an airflow enhancement device, which can cool the center of the lamp holder more appropriately High temperature and improve heat dissipation efficiency.一種氣流式氣冷燈組，包含一燈座、一光源、一散熱鰭片以及一散熱單元，該散熱單元包含一無扇葉風扇並具有一氣體輸出通道，以及至少一個送風馬達設置於該無扇葉風扇， 該氣體輸出通道與該送風馬達連接處皆設有一控制閥門能夠使該氣冷燈組達到多段式且大風量的運轉，並能夠延長使用壽命，其中有一上蓋設置於該燈座，交接處還夾設有防水膠環，可確實防止海水與空氣侵蝕而損壞該燈組，另外使用者可藉由裝設氣流增強裝置達到二次以上之氣流增益，可更適切的冷卻燈座中心的高溫及提升散熱效率。
