Abstract:
1. A lamp comprising: (a) a light source; (b) a cylindrical sleeve surrounding the light source having a sleeve upper end and a sleeve lower end, the cylindrical sleeve defining a central axis; (c) first and second elongated frame members disposed about the sleeve, each elongated frame member comprising an upper end inner support member and an upper end outer support member which jointly form a clamping spring on the sleeve upper end, each elongated frame member further comprising a lower end inner support member and a lower end outer support member, wherein the clamping spring is arranged so that in the clamping position the sleeve upper end is clamped between the upper end outer support member and the upper end inner support member and the clamping spring applies force against the sleeve upper end to press the sleeve lower end into the lower end inner and outer support members, thereby fixing the position of each elongated frame member on the sleeve in the direction of the central axis, wherein the clamping spring fixes the position of each elongated frame member on the sleeve in a direction perpendicular to the direction of the central axis.
