PROBLEM TO BE SOLVED: To provide a light source module prevented from unexpectedly falling down when set up at a high place.SOLUTION: A connection part 21 and an uneven part 22 include: first screw-down parts (a first insertion hole 211, a first female screw 221 and a mounting screw 214) for connecting them to each other; and second screw-down parts (a second insertion hole 213, a second boss 222, a second female screw 223 and a washer-attached screw 224). The second screw-down parts include: a columnar boss (the second boss 222) having a screw hole (the second female screw 223); an insertion hole (the second insertion hole 213) through which the boss is inserted; and a screw (the washer-attached screw 224) the screw part of which is screwed into the screw hole and the outer diameter of the head part of which is larger than the inner diameter of the insertion hole. Accordingly, the head part of the screw 224 screwed into the second female screw 223 and a washer 2240 do not pass through the second insertion hole 213 even when the mounting screw 214 is disengaged, so that light source modules A2, A3 are prevented from falling down. |
