Light distribution yes deformation projector lamp

摘要

(57) Abstract Objective Shaking lighting luminous flux on left and right, tool the light intensity of the whole lightBe able to maintain, the light distribution yes deformation which is not the times when decrease of visibility is causedThe projector lamp is formed. Constitution On cartridge head of elliptic reflected mirror surface 6 valve 7 for illuminationThe reflector 3 which facilities is done shift, rear light of collimator glass lens 1Vis-a-vis axis L1 being devoted or parallel displacement w unrestrictedly rihurekuYou install with ta displacement support feature 4. Collimator runLens aperture of zu 1, axial length of displacement direction of reflector 3It makes elliptic form than axial length of other direction or the ellipse form which becomes long,It is it is the thing.
