An LED lamp includes a lamp support and a light-source module mounted on the lamp support. The lamp support includes a main post and a branch post extending from the main post. The main post is tubular and defines a first airflow tunnel inside the main post. The branch post is tubular and defines a second airflow tunnel inside the branch post, and the second airflow tunnel is directly communicated with the outer environment. The first and second airflow tunnels are communicated with each other. The light-source module is located at a position through which an airflow from the first and second airflow tunnels of the main post and the branch post flows.
