A light source module and a projection apparatus including the light source module, an optical engine module, and a projection lens are provided. The light source module includes a lamp holder, a casing, a light source, and a heat dissipation fan. The lamp holder has a cover having a first inlet and a first outlet. The casing is connected to the lamp holder and has a second inlet and at least one second outlet. The light source is fixed to the lamp holder fixed to a housing of the projection apparatus. The heat dissipation fan generates a heat dissipation airflow through an outflow side. A first part of the heat dissipation airflow enters the cover through the first inlet, and leaves the cover through the first outlet. A second part of the heat dissipation airflow enters the casing through the second inlet, and leaves the casing through the second outlet. |
