The present invention relates to a lamp primarily for projectors, which lamp comprises at least one light source, which light source is formed of at least one Electrode Less Plasma Source (ELPS), which light sources comprises a light bulb comprising a plasma material, which plasma material is excited to emit light by electromagnetic radiation, which lamp comprises at least a first reflector, which light source is placed inside the first reflector, which lamp further comprises at least a second reflector. The present invention further concerns a method for forming a beam of light generated from an ELPS light source, where the light is concentrated by a first reflector and where the light is further concentrated in a second reflector.
Lamp primarily for projectors, which lamp comprises at least one light source, which light source is formed of at least one Electrode Less Plasma Source (ELPS), which light sources comprises a light bulb comprising a plasma material, which plasma material is excited to emit light by electromagnetic radiation, which lamp comprises at least a first reflector, which light source is placed inside the first reflector, which lamp further comprises at least a second reflector, whereby the second reflector is formed as a cone, which cone comprises a highly reflective inner surface, in which cone parts of the generated light is multi reflected at the inner side of the cone.
Method for forming a beam of light generated from an ELPS light source, where the light is reflected by a first reflector and where the light is further reflected in a second reflector, whereby the second reflector is cone shaped, in which cone shaped reflector the light is reflected into a mostly homogenous light beam.
Light source and reflector system, which light source is formed of at least one Electrode Less Plasma Source (ELPS), which light sources comprises a light bulb comprising a plasma material, which plasma material is excited to emit light by electromagnetic radiation, which reflector system comprises at least a first reflector, which light source is placed inside the first reflector, which reflector system further comprises at least a second reflector, whereby the second reflector is formed as a cone, which cone comprises a highly reflective inner surface, in which cone parts of the generated light is multi reflected at the inner side of the cone.
