A lamp includes a lampwick, a reflector, and a shade. The reflector has an opening and a bottom portion opposite to the opening. The lampwick is disposed at the bottom portion and passes through the bottom portion and at least one part of the lampwick is disposed in the reflector. The shade disposed outside the reflector covers a part of the reflector. The shade connected to the bottom portion has an inlet and an outlet. The inlet and the outlet are disposed at two opposite sides of the reflector respectively. An air flow flows into the space between the reflector and the shade through the inlet. At least one part of the air flow flows through the outlet along a flowing direction. An included angle defined between the flowing direction and a transmitting direction of an illumination light beam formed by the reflector is an acute angle.
