摘要： A light valve device includes a light valve disposed adjacent to a circuit board, and a heat-dissipating structure including a heat-dissipating main body and a heat-dissipating block. The heat-dissipating main body is disposed opposite to the light valve, and is formed with a groove defined by a first contacting surface and two engaging surfaces. The first contacting surface extends in a longitudinal direction perpendicular to the vertical direction and has two opposite longitudinal edges. The engaging surfaces respectively extend from the longitudinal edges and define an open side of the groove opposite to the first contacting surface in the vertical direction. The open side has a width in the transverse direction smaller than that of the first contacting surface. An engaging portion of the heat-dissipating block is disposed in the groove so that a second contacting surface is in contact with the first contacting surface.

摘要： A lighting module includes a light source, a heat sink, a case, and a fan. The light source has a light emitting surface and a bottom surface opposite thereto. The heat sink is disposed at the bottom surface of the light source and includes a heat sink mass having a heat dissipation surface, wherein the heat dissipation surface is opposite to the bottom surface. The case is disposed to the heat sink and has a module airflow inlet and a module airflow outlet. The fan is disposed to the case or the heat sink for driving airflow to sequentially pass through the module airflow inlet, the heat sink, and the module airflow outlet. The case is capable of making the flowing direction of the airflow passing the module airflow outlet the same as the light emitting direction of the light emitting from the light emitting surface.
