An illumination module includes a substrate and a plurality of LED devices. The substrate has a main plane, and the main plane includes a central region and a peripheral region. The LED devices are disposed on the main plane of the substrate in the central region and peripheral region. Each of the LED devices has a light-exiting direction, where the light-exiting direction of the LED device disposed in the central region is substantially perpendicular to the main plane, and the light-exiting direction of each of the LED devices in the peripheral region goes outwards with respect to the central region.
