Claims

[Claims for Utility Model Registration] (1) Normally, one secondary mirror 2 in a headlamp, whose surface on the bulb side is a reflective surface, directs the light directly reflected by the primary mirror 1 to the bulb 3. By moving between the primary mirror 1 and the primary mirror 1, the secondary mirror reflects light in that direction onto a different primary mirror surface than usual, and by changing the illuminance distribution of the irradiated light reflected by the opposite mirror surface, A stepless optical axis adjustable headlight whose purpose and feature is to have the same effect as changing the optical axis. (2) By operating the secondary mirror operation rod 4, the secondary mirror 2 in the headlight can rotate steplessly in any direction around the fixed fulcrum A. Registration of a utility model whose purpose and feature is that the range of light reflected by the headlight can be changed arbitrarily, and therefore the illuminance distribution of the headlight can be adjusted arbitrarily and steplessly. A stepless optical axis adjustable headlamp according to claim 1. (3) The piston rod 51 of the electromagnetic piston device reciprocates depending on the magnitude and direction of the voltage applied to the electromagnetic coil 56 of the electromagnetic piston device 5 fixed to the headlight outside the headlight, and the reciprocating motion is Secondary mirror operation rod 4
However, by converting the secondary mirror into a rotational movement centered on a fixed fulcrum point A, the amount and direction of rotational movement of the secondary mirror can be adjusted. The utility model as set forth in claim 1 of the utility model registration claim, characterized in that it has a device,
Headlight with stepless optical axis adjustment. (4) Using the electric motor 9 instead of the electromagnetic piston device 5, the rotation of the electric motor is reduced by the speed reduction device 91.
Utility model registration claim 1, characterized in that the secondary mirror 2 is rotated about a fixed fulcrum A by decelerating the rotation and transmitting the rotation to the secondary mirror operating rod 92. A headlight with a stepless optical axis adjustment as described.
