Abstract

A light emitting assembly includes at least one light emitting device (20) having a thermally conductive diode seat (22) and a light emitting diode (21) mounted on the diode seat (22), and a thermally conductive heat-dissipating device (10) having a seat body (100) that has an upper surface (101) on which the diode seat (22) is mounted. The seat body (100) is provided with a plurality of fins (103) that project therefrom and that are spaced apart from each other.
