We present a model aimed to reproduce the infrared brigtness distribution of the Galaxy, as observed by the COBE-DIRBE experiment, and by the Japanese balloon flights (eg. Hayakawa et al., 1981). Based on the disk brightness profiles of a sample of spiral galaxies, and on the observed brigthness distribution of bars, we adopted new mathematical expressions to represent each component (bulge, bar, disk, spiral arms).
