DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting door window panel structure.

[0002]

2. Description of the Related Art There is a door window panel of a vehicle having a structure in which a lamp is attached to a lower edge. In other words, there is a type in which a light beam emitted in a fan shape from this lamp is made incident on the inside of the plate thickness surface of the door window panel, and the light beam is emitted from the upper edge of the door window panel, thereby emitting light at the upper edge. (A similar technique is disclosed in
No. 343).

[0003] Generally, the lower edge of the door window panel is in a horizontal state, so that the lamp mounted on the lower edge of the door window panel is mounted vertically upward. Accordingly, the central axis of the light beam emitted from the lamp in a fan shape in the thickness plane of the door window panel is also in a vertical state, and the upper side ends of both sides having the central axis as a symmetric axis emit light.

[0004] In this manner, by illuminating the upper edge of the door window panel, the occupant is informed of the presence of the upper edge.
It is possible to prevent the upper edge of the door window panel of the sashless door from hitting a part of the occupant's body.

[0005]

However, in such a conventional technique, light is emitted from the upper edges of both sides of the central axis extending directly above the lamp and having the central axis as a symmetric axis.
If the shape of the window panel is symmetrical with respect to the center axis, the upper edge can be made to emit light uniformly, but, for example, one of the upper edges of the upper edges on both sides of the center axis. If the end is long, the portion of the longer upper end far from the central axis becomes dark, and a uniform light emitting state cannot be obtained.

The present invention has been made by paying attention to such a conventional technique, and can emit light uniformly over the entire upper edge of the door window panel, particularly around the center point of the upper edge. The present invention provides a type door window panel structure.

[0007]

According to a first aspect of the present invention, a lamp mounted on the lower edge of the door window panel emits a fan-shaped light beam within the thickness of the door window panel. In the light-emitting door window panel structure capable of emitting light at the upper edge of the door window panel, the mounting angle of the lamp with respect to the lower edge of the door window panel is determined by adjusting the center axis of the light emitted from the lamp to the upper edge of the door window panel. It is characterized in that it is set to match the center point of the part.

According to the first aspect of the present invention, since the central axis of the light emitted from the lamp coincides with the central point of the upper edge of the door window panel, the upper edge of both sides of the central axis. The light emission lengths of the ends become equal, and the entire upper side end can emit light uniformly.

According to a second aspect of the present invention, in the light emitting door window panel structure according to the first aspect, the mounting position of the lamp is such that a distance from the lamp to an upper edge of the door window panel is limited. It is characterized in that the positions are set to be substantially equal.

According to the second aspect of the present invention, since the distance from the lamp to the upper edge of the door window panel is substantially equal, unevenness in luminance does not occur at the entire upper edge, and the entire upper edge is improved. Light can be emitted uniformly.

According to a third aspect of the present invention, in the light emitting door window panel structure according to the first or second aspect, the shape of the upper edge of the door window panel is changed from the lamp to the door window. The panel is formed so that the distance to the upper edge of the panel is substantially equal.

According to the third aspect of the present invention, since the distance from the lamp to the upper edge of the door window panel is substantially equal, unevenness in luminance does not occur at the entire upper edge, and the entire upper edge is improved. Light can be emitted uniformly.

According to a fourth aspect of the present invention, there is provided the light emitting door window panel structure according to any one of the first to third aspects, wherein the mounting surface of the lamp at the lower edge of the door window panel is a light beam. Is formed at an angle orthogonal to the central axis of

According to the fourth aspect of the present invention, since the mounting surface of the lamp at the lower edge is formed at an angle perpendicular to the central axis of the light beam, the refraction of the light beam on the mounting surface is small.
Light rays can enter the door window panel in a wide angle fan shape.
