A lamp includes a combustion chamber having a neck that defines a combustion chamber air outlet. A candle is disposed in the combustion chamber and, when burned, creates an upward flow of air and combustion products through the neck. A reservoir is disposed around a portion of the neck with a material to be heated disposed in the reservoir. In one configuration, the material is a candle fuel that is wicked by the neck and drips into the candle to refuel the candle. In another configuration, the material is a scented material that evaporates when heated to distribute the scent. A cooling chamber may be disposed above the combustion chamber with the outlet of the cooling chamber being disposed below the outlet of the neck. Another configuration allows the height of the flame to be adjusted by varying the volume of air allowed to be drawn into the unit. |
