AI Technical Summary
Technical Problem
Conventional vehicle lamps with cylindrical light guides struggle to achieve a thinner light emitting profile due to the thickness of the outer lens and lamp body, limiting further narrowing of the light emitting width.
Method used
The vehicle lamp design incorporates a columnar light guide with a plate-like emitted portion and a flange portion, where the light guide and lamp body are joined by flange portions, eliminating the need for an outer lens and allowing for a narrower light emitting width.
Benefits of technology
This design enables a vehicle lamp that emits light in a thin line shape with a high design aesthetic, reducing the overall size of the lamp and simplifying manufacturing processes while preventing leakage light.

Abstract
To provide a vehicular lighting fixture having high designability by narrowing the appearance in light emission.SOLUTION: A vehicular lighting fixture 100 includes: at least one light source 8; a light guide body 4 extending in a prescribed direction and including a columnar light guide portion 42 guiding the light emitted from the light source 8, a plate-shaped emission portion 43 continued from an outer peripheral surface of the light guide portion 42, extended outward, and emitting the light guided by the light guide portion 42 outward, and a flange portion 48 formed on outer peripheral edges of the light guide portion 42 and the emission portion 43; and a lamp body 2 having a shape matched to the light guide body 4, having a body flange portion 24 on an outer peripheral edge, and defining the light guide body 4 and a lamp chamber 6. The light guide body 4 and the lamp body 2 are joined by the flange portion 48 and the body flange portion 24.SELECTED DRAWING: Figure 3
