Patent ID: 7367687

Claim:
An illumination system, suitable for providing a parallel illumination beam, the illumination system comprising: two first lamps, each of the first lamps comprising: a first lampshade, having a first light outputting section; a first burner, disposed in the first lampshade, the first burner providing a first diverging light; a first reflector, connected with the first lampshade and covering a portion of the first light outputting section, wherein the first lampshade and the first reflector transform the diverging light into a first parallel light beam, and the first parallel light beam is emitted from a portion of the first light outputting section without covering by the first reflector; at least one second reflector, disposed between the first lamps to reflect and combine the first parallel light beams into the parallel illumination beam; at least one second lamp, disposed between at least one of the first lamps and the second reflector, wherein the second lamp comprises: a second lampshade, having a second light outputting section; a second burner, disposed in the second lampshade, the second burner providing a second diverging light and the second lampshade transforming the second diverging light into a second parallel light beam; and at least one third reflector, disposed in front of the second light outputting section of the second lampshade, wherein a portion of the second parallel light beam is reflected by the third reflector to one of the first lamps, the other portion of the second parallel light beam propagates to the second reflector, and a portion of the first parallel light beams is reflected to the second reflector by the third reflector and the second lampshade.
