Abstract
Abstract A directed beam of intense light radiation is produced from a lamp arrangement having a vapor tube light source producing relatively less intense omnidirectional light radiation and having coaxial tubular walls with the inner tubular wall defining an axial region where the light is concentrated by a reflector surrounding the outer tubular wall. The concentrated light radiation is collected and transformed into a beam of greater intensity by a cylindrical light-transparent member located in the axial region and having reflector means on one end for causing the light to pass through the other end. The lighttransparent member is spaced-apart from the inner wall of the light source and has an index of light refraction greater than a medium in the surrounding space so as to enable light passing through the transparent member to be reflected internally at the cylindrical surface of the member. To provide substantially total internal reflection of light entering the transparent member normal to the axis thereof, the reflector means includes a conical portion extending axially inside the cylindrical transparent member, with an angle of revolution about the axis substantially equal to half the critical angle for total internal reflection inside the light-transparent member.
