Abstract: An optical integrator for an illumination device of a microlithographic projection exposure system has a rod made of a material transparent for ultraviolet light and with a rectangular cross-section. A rod arrangement with, for example, seven small rods made of the same material is arranged before the entrance surface of the rod. The aspect ratio between width and height of the small rods is the inverse of the aspect ratio between width and height of the rod. The rod arrangement, or some analogous structure, surface or treatment substituted therefor, serves to compensate the direction-dependent total reflection losses of the rod.

Abstract: A folding structure of a two-layer lampshade is disclosed. The folding structure has a top ring at a topmost of the lampshade, a bottom ring having a diameter larger than that of the top ring, and a supporting frame between the top ring and the bottom ring. A plurality of supporting rods extend from a ring edge of the top ring toward a center of the top ring. The supporting frame is formed by a plurality of longitudinal rods and a plurality of transversal rods. Since the supporting frame is engaged to the bottom ring by the buckle, it can rotate to be positioned horizontally by using the buckles as fulcrums and the inner cloth and outer cloth of the lampshade encloses the folding structure. Thereby, the lampshade is assembled to have a smaller volume, As a consequence, the transfer cost is reduced.

Abstract: A vehicle cornering lamp capable of broadly irradiating a road surface ahead of and in an oblique direction of a vehicle while the vehicle is moving around a curve. The vehicle cornering lamp includes three reflector units 12A, 12B, and 12C, whose light emitting directions are respectively set to angles of 30°, 45°, and 60°, with respect to the traveling direction of the vehicle. The vehicle cornering lamp also includes a control unit 20 for controlling light emission—from the reflector units 12A, 12B, and 12C—according to the travel conditions of the vehicle. When the vehicle turns to the left at an intersection, a traveling road onto which the vehicle will turn left, and a road shoulder, are sufficiently irradiated by switching on the reflector units 12A, 12B and 12C in the order of 12A→12B→12C→12B→12A, so that pedestrians can quickly be detected.

The reflector collar has a predetermined contour and a plurality of reflector impressions formed into the predetermined contour. The predetermined contour and the plurality of reflector impressions provide directional illumination control for the optical assembly.

Abstract: Since a light source lamp (11) and a reflector (12) of a lamp unit (10) are respectively fixed to a lamp housing (13) in a mutually independent manner, an attachment for attaching and fixing the light source lamp (11) is not necessary to be formed on the reflector (12) as an optical component, so that the shape of the reflector (12) can be simplified and accuracy of a reflection surface (121), especially at a bottom thereof, can be easily improved, thereby enhancing illumination of the lamp unit (10).
