A light device for curing a dental composition, comprising a light-source, a housing, a passive heat sink, first and second thermal pathways enabling heat transfer between the light source and the heat sink as well as between the heat sink and the housing. The first thermal pathway is dominated by thermal conduction, and the second thermal pathway is dominated by thermal radiation and thermal convection. The invention helps to provide an inexpensive and compact design of the device.
