PROBLEM TO BE SOLVED: To provide a light source module which does not need to prepare heat radiation fins having heat radiation amounts adapted to luminosity levels of respective lighting fixtures, also does not need to prepare common heat radiation fins adaptable to all the luminosity levels, and is adapted to the luminosity levels required by the lighting fixtures.SOLUTION: A light source module comprises an attachment base board 1 having a plurality of penetration holes 2 formed therein, and a heat radiation base board 3 having an LED 5 as a light source on one face, and heat radiation fins 4 for radiating heat generated by the LED 5 on the other face. The heat radiation base board 3 is attached to the attachment base board 1 so that the LED 5 is arranged at the penetration hole 2 side. |
