The light-emitting module according to the present invention comprises a heat dissipation element, a substrate for example a metal core printed circuit board (MCPCB), or FR4 board which is coupled to one or more light-emitting elements and provides a means for operative connection of the light-emitting elements to a source of power. The substrate is positioned such that it is thermally coupled to the heat dissipation element. The light-emitting module further comprises a housing element which matingly connects with the heat dissipation element, wherein the housing element may further comprise an optical element integrated therein for manipulation of the light generated by the one or more light-emitting elements.
