An epilating apparatus, comprising a housing, a light emitting mechanism and the heat dissipating mechanism of any of the preceding claims 1 to 5, wherein the housing is provided with an air inlet, an air outlet and a light outlet, and the light emitting mechanism and the heat dissipating mechanism are both assembled inside the housing; wherein an airflow path is present such that when the fan is operated, air flows along the airflow path from the air inlet to the air outlet, the fan being located in the airflow path downstream of the air inlet, the cold-conductive element extending into the airflow path upstream of the fan, and the heat-radiating element extending into the airflow path downstream of the fan.
7. An epilating apparatus as claimed in claim 6, wherein the heat-conducting assembly is located in the air flow path downstream of the cold-conducting member.
8. The epilator as claimed in claim 6, further comprising a light-transmissive crystal and a second cooling member, the light-transmissive crystal being mounted at the light exit of the housing, the second cooling member being mounted inside the housing, the second cooling member comprising a cold surface that can be cooled relative to ambient temperature and a hot surface that can be heated relative to ambient temperature, the cold surface being in contact with the light-transmissive crystal and the hot surface being in contact with the heat-conducting element.
9. An epilator as claimed in claim 6, wherein the light-emitting means comprises a light source and a light reflector, the light source being secured between the light reflector and the light outlet, the light reflector being in contact with the heat-conducting member.
10. An epilator as claimed in claim 6, characterized in that the epilator comprises a control circuit board, the cold-conducting member being in contact with the control circuit board.
