Four stellar complexes (star forming regions) in the LMC have been investigated using IRAS observations and starcounts in the optical region (U magnitude). The optical data allow us to detect such structures and give information on the age range of their stellar component. Under the assumptions of this age range, a Salpeter IMF and two different mechanisms of star formation rate (instantaneous and constant), we derived the expected flux in the optical and infrared wavelengths in order to compare them with the observed ones. The expected flux at the U magnitude (in the optical window) for the adopted range of ages (106.5-108.5 years) has been found comparable to the one derived from our starcounts within the errors. However, the infrared luminosity has been found to exceed systematically at least 10 times the U luminosity. We suggest that the excess far-infrared energy must be searched to the far UV radiation wavelengths.
