Beschreibung
Zusammenfassung:	A light source device having a good heat dissipation capability is disclosed, in which heat generated by a light emitting device is conducted to a base fabricated by a porous material through a heat conducting mask or a heat conducting pipe. Due to a large area contact between the heat conducting mask or the heat conducting pipe and the base, the heat can be evenly conducted to the base, so that the base can absorb the heat and dissipate the heat to external, so as to improve a heat dissipation efficiency. Moreover, in the light source device of the disclosure, heat exchange of the light emitting device can be directly carried on through air convection, so that the heat generated by the light emitting device can be taken away from the light source device through heat exchange of cool air.
