Title: Light source system with open flames

Description:
DETAILED DESCRIPTION 
   An open flame always creates a comfortable atmosphere by emitting light in the spectral range of warm colors. Because the resulting ambience is unique, you can still find such simple and archaic light sources widely spread in all domains of human life today, especially in the domestic and gastronomy sectors. Referenced in historical documents and available on today&#39;s market, you can find innumerable varieties of such light sources, however, they all have upward-burning flames. 
   The purpose of this patent application is to propose a new light source system which changes the flame direction from upwards to horizontal or even downwards through simple means. 
   The system combines at least one downward-directed open flame and at least one heat source, which can also be a light source. Each is placed in a leg of an u-shaped tube-like container where the two open ends are pointed up. In the bottom of one of these legs, an upward-directed heat source is placed, which generates an air stream through both legs. In the other leg, a downward-directed flame (light source) burns, which is pulled downwards more strongly by the air stream. 

   The invention is described in more detail in FIG.  1 .  FIG. 1  shows a possible arrangement of the components of the light source system described previously. The number ( 1 ) represents the outer body of the system, which is made of a non-flammable material such as glass. Area A stands for the oil-filled reservoir and the lit wick of the oil lamp. A first removable glass cylinder ( 2 ), placed in the Area A serves as a funnel for a first oil lamp ( 3 ) which is positioned within the first removable glass cylinder ( 2 ). This glass cylinder ( 2 ), the body ( 1 ) and the second glass cylinder ( 6 ) together form a u-shaped container. Inside the container is a heat source and a light source in this case both oil lamps consisting of wicks ( 3 ), removable wick tubes ( 4 ) and oil reservoirs ( 5 ). If the first oil lamp is lit (Area A), an upward air stream is generated in the first cylinder ( 2 ). Since the second cylinder ( 6 ) is connected to the first cylinder ( 2 ) via the body ( 1 ), a downward air stream is generated in the second cylinder ( 6 ). If the second oil lamp in the second cylinder ( 6 ) is now lit, the flame bums downwards, provided the wicks are adjusted correctly.
