である。[Detailed description of the invention] <Industrial application field> The present invention relates to automobile headlights, and more specifically, the present invention is concerned with the function of a headlamp that emits white light and the function of a fog lamp that emits yellow light in one light chamber. This invention relates to an automobile headlamp that has both functions.

所要の配光が得られなくなる不具合を生じる。<Prior Art> This type of automobile headlamp is disclosed in Japanese Utility Model Application No. 61-202802, which was previously proposed by the applicant of the present invention. What we proposed earlier was a headlamp that emits white light and a fog lamp that emits yellow light by rotating a globe whose upper half is colorless and transparent and whose lower half is yellow by rotating it half a turn around the bulb. Because the lamp was configured to perform two functions, when the bulb was turned on, white light and yellow light inevitably mixed together, resulting in a problem in which the functions of the headlamp and fog lamp tended to become unclear from each other. However, in order to prevent white light and yellow light from mixing, using only the upper half of the reflector or the upper half of the bulb can contribute to light distribution. A problem occurs in which the amount of light is halved and the desired light distribution cannot be obtained.

There are no space constraints, and at the same time there are no design constraints. Moreover, the glove holder that supports the yellow glove is moved in the front and back direction using a parallel movement link that moves in parallel in the front and back direction and a drive arm that swings in the horizontal direction, so a high propulsive force for back and forth movement can be obtained. It will be done.
