An illuminator, particularly for street lighting and industrial applications, comprising a light source including a gas discharge tube, a closed outer vessel for receiving the gas discharge tube, composed from a rear half part and a front half part for forwarding light of the light source, at least the front half part made of light transparent material, light reflecting means covering partly the inner surface of the rear half part of the outer vessel, mechanical fitting elements and electric connecting means, wherein the front half part and the rear half part both are symmetric to at most two symmetry planes and one of the symmetry planes includes the longitudinal axis of the gas discharge tube and constitutes the symmetry plane of the light emitted by the light source. The proposed illuminator require small place and is hardly subject to contamination originated from the environment.
An illuminator, particularly for street lighting and industrial applications, comprising a light source including a gas discharge tube, a closed outer vessel for receiving said gas discharge tube, said vessel comprising a rear half part and a front half part for forwarding light of said light source, at least said front half part being made of light transparent material, light reflecting means partly covering the inner surface of said rear half part of said outer vessel, mechanical fitting elements and electric connecting means, wherein said front half part and said rear half part are each symmetric relative to first and second symmetry planes and said first symmetry plane includes the longitudinal axis of said gas discharge tube, said longitudinal axis of said gas discharge tube being perpendicular to said second symmetry plane, and said rear half part having a curved profile comprising two concavities in said second symmetry plane and a curved profile comprising one concavity in said first symmetry plane.
An illuminator, particularly for street lighting and industrial applications, comprising a light source including a first gas discharge tube, a closed outer vessel made at least partly of hard glass by pressing for receiving said first gas discharge tube in a hermetically closed space of less than atmospheric pressure, light reflecting means partly covering the inner surface of said outer vessel, mechanical fitting elements and electric connecting means separated from said mechanical fitting elements, wherein said outer vessel consists of a rear half part for receiving said light reflecting means and a front half part connected to said rear half part along a straight connecting plane, said rear half part and said front half part each being symmetric to a first symmetry plane lying perpendicular to said connecting plane, said first symmetry plane including the longitudinal axis of said first gas discharge tube, said longitudinal axis of said gas discharge tube being perpendicular to said second symmetry plane, and said rear half part having a curved profile comprising two concavities in said second symmetry and a curved profile comprising a single concavity in said first symmetry plane.
