An illuminating system includes a system casing and a plurality of illuminating modules. The system casing has a first air-hole area and a plurality of second air-hole areas. One of the adjacent second air-hole areas keeping a first distance from each other keeps a second distance from the first air-hole area. The other one of the adjacent second air-hole areas keeps a third distance from the first air-hole area. The first distance is smaller than or equal to the second distance and smaller than or equal to the third distance. Each illuminating module disposed at the system casing includes a diversion casing having a third air-hole area and a fourth air-hole area. The third air-hole areas are located within the system casing and communicate with the first air-hole area. The adjacent second air-hole areas are respectively corresponding to and respectively communicate with the fourth air-hole areas of different illuminating modules. |
