A lighting device, comprising: at least a light source, at least one reflector and a support structure, the reflector comprising at least a first reflector region, a second reflector region and a third reflector region, the light source on the support structure, characterised in that an entirety of the third reflector region is positioned on a side of a plane of emission of the light source that is opposite to a side of the plane of emission of the light source into which light is emitted by the light source, and the support structure is attached to the third reflector region, wherein the first reflector region, the second reflector region and the third reflector region are configured such that when the light source is illuminated: a first portion of light emitted by the light source is reflected by the first reflector region and then by the third reflector region, a second portion of light emitted by the light source is reflected by the second reflector region and forms a primary beam of light exiting the lighting device, the primary beam of light of a shape that is of a minimum cross-sectional area, at a first distance from the lighting device, that encompasses at least 75% of the light reflected by the second reflector region, and at least 5% of the first portion of light that is reflected by the third reflector region is within the primary beam of light. at least a light source, at least one reflector and a support structure, the reflector comprising at least a first reflector region, a second reflector region and a third reflector region, the light source on the support structure, characterised in that an entirety of the third reflector region is positioned on a side of a plane of emission of the light source that is opposite to a side of the plane of emission of the light source into which light is emitted by the light source, and the support structure is attached to the third reflector region, wherein the first reflector region, the second reflector region and the third reflector region are configured such that when the light source is illuminated: a first portion of light emitted by the light source is reflected by the first reflector region and then by the third reflector region, a second portion of light emitted by the light source is reflected by the second reflector region and forms a primary beam of light exiting the lighting device, the primary beam of light of a shape that is of a minimum cross-sectional area, at a first distance from the lighting device, that encompasses at least 75% of the light reflected by the second reflector region, and at least 5% of the first portion of light that is reflected by the third reflector region is within the primary beam of light. a first portion of light emitted by the light source is reflected by the first reflector region and then by the third reflector region, a second portion of light emitted by the light source is reflected by the second reflector region and forms a primary beam of light exiting the lighting device, the primary beam of light of a shape that is of a minimum cross-sectional area, at a first distance from the lighting device, that encompasses at least 75% of the light reflected by the second reflector region, and at least 5% of the first portion of light that is reflected by the third reflector region is within the primary beam of light.
