With this design, when the adjacent two light source devices 100 are connected to each other to form a combined luminaire, the electrical connection device 500 can be completely hidden. Since the electrical connection device 500 does not emit light, this design can reduce the area that does not emit light after combination, and increase the visual effect of the integratedness of the lamp. In addition, the design of the light source module 300 disposed between the connecting base 400 and the lamp cover 210 can further reduce the area of non-light-emitting between the two light-emitting surfaces 210, so that the continuity of the light-emitting area is improved. In addition, the shortest distance between the first supporting surface 231, the second supporting surface 232, and the third supporting surface 233 and the electrical connecting device 500 is preferably the same.
