摘要： Spinnable balls each having two surfaces with different optical characteristics can be produced by forming a plurality of balls with the same specific gravity on a thermoplastic film, and softening the thermoplastic film by controlling a heating temperature thereof based on the specific gravity of the balls so that the hemispheres of the balls are embedded into the thermoplastic film by their own weight. A layer having different optical characteristics from those of the balls is then formed on the exposed surface of each ball. Finally, the balls provided with the layers are detached from the thermoplastic film.

摘要： A light-emitting element is disposed to face the front side such that an end point of a rectangular or square light-emitting chip corresponding to the vehicle's own lane is positioned at a rear focal point of a convex lens. An additional lens is disposed to surround the convex lens. The additional lens includes an incident surface, a reflection surface, and an emitting surface. The additional lens is divided into a-plurality of fan-shaped areas in a circumferential direction with respect to an optical axis Ax. The division is performed for each angular range where a corner point of the light-emitting chip, which is positioned at an uppermost end of an image of the light-emitting chip formed on the reflection surface by the light emitted from the light-emitting element, becomes the same corner point.

摘要： A vehicle lamp includes a convex lens and a light emitting device. Light directly reaching a rear surface of the convex lens from the light emitting device is deflected through the convex lens to form a light distribution pattern having a horizontal cutoff line and an oblique cutoff line. The light emitting device includes a light emitting chip having a rectangular light emitting surface oriented to face the rear surface of the convex lens, and a corner of the rectangular light emitting surface is disposed on a rear focal point of the convex lens. A front surface of the convex lens includes a horizontally diffusing region which diffuses a part of the light in the horizontal direction, and an obliquely diffusing region which diffuses another part of the light toward the self lane side in an oblique direction forming an upward angle with respect to the horizontal plane.
