Abstract

A vehicle signal lamp can include a first lamp unit, a second lamp unit and a boundary between the first and second lamp units so as to be attached continuously to vehicles including a trunk lid. Each of at least one first light source, at least one second light source and a boundary light source can be located in the first lamp unit including a first outer lens and the second lamp unit including a second outer lens, respectively. Each of the first light source and the second light source can emit light from the first outer lens and the second outer lens, respectively, and also the boundary light source can illuminate the boundary by using the second outer lens. Thus, the vehicle signal lamps with a simple structure can be used for various signal lamps, and which can provide a favorable light distribution as one continuous favorable light-emitting pattern.

First claim

What is claimed is:

1 . A vehicle signal lamp comprising:
a boundary; a first lamp unit including a first casing having a first opening, a first outer lens having a first inner portion, and a first lamp room, the first outer lens attached to the first casing and covering the first opening of the first casing, and thereby the first lamp room formed between the first casing and the first outer lens, and the first inner portion of the first outer lens extending in a direction toward the first casing from the first outer lens along the boundary; at least one first light source having a first light-emitting direction located in the first lamp room, and the first light-emitting direction of the first light source being directed toward the first outer lens of the first lamp unit; a second lamp unit including a first casing having a second opening, a second outer lens having a second inner portion, and a second lamp room, the second outer lens attached to the second casing and covering the second opening of the second casing, and thereby the second lamp room formed between the second casing and the second outer lens, and the second inner portion of the second outer lens extending in a direction toward the second casing from the second outer lens along the boundary, and therefore facing the first inner portion of the first outer lens via the boundary, which is located between the first lamp unit and the second lamp unit, the second inner portion of the second outer lens including a second inner end surface, a second outer surface and a second inner surface located in an opposite direction of the second outer surface, and substantially facing the boundary, the second inner surface of the second inner portion including a plurality of concavo-convex surfaces, which extends in a substantially horizontal direction of the vehicle signal lamp; a boundary light source having a boundary light-emitting direction facing the second inner end surface of the second outer lens, and the boundary light-emitting direction of the boundary light source being directed toward the second inner end surface of the second outer lens; and at least one second light source having a second light-emitting direction located in the second lamp room, and the second light-emitting direction of the second light source being directed toward the second outer lens of the second lamp unit.

2 . The vehicle signal lamp according to claim 1 , wherein the at least one first light source is used as a light source for at least one of a tail lamp and a stop lamp.

3 . The vehicle signal lamp according to claim 1 , wherein the at least one second light source is used as a light source for at least one of a tail lamp and a stop lamp.

4 . The vehicle signal lamp according to claim 1 , wherein at least one of the at least one first light source, the boundary light source and the at least one second light source is a light-emitting diode.

5 . The vehicle signal lamp according to claim 1 , further comprising:
a second incident surface connecting to each of the second outer surface and the second inner surface of the second outer lens located in an opposite direction of the second inner end surface of the second outer lens; and a second boundary light source having a second optical axis facing the second incident surface, and the second optical axis of the second boundary light source intersecting with the incident surface at a substantially right angle.

6 . The vehicle signal lamp according to claim 5 , wherein an incident angle of the second boundary light source is less than 90 degrees with reference to the second outer surface of the second inner portion.

7 . The vehicle signal lamp according to claim 1 , further comprising:
a first incident surface connecting to the second inner end surface of the second inner portion, being located toward the second casing, facing the boundary light source, and be directed toward the boundary light-emitting direction of the boundary light source.

8 . The vehicle signal lamp according to claim 1 , further comprising:
a first shade be attached to the second casing; and a second shade attached to the casing, wherein each of the first shade and the second shade surrounds the boundary light source.

9 . The vehicle signal lamp according to claim 7 , further comprising:
a first shade be attached to the second casing; and a second shade attached to the casing, wherein each of the first shade and the second shade surrounds at least one of the boundary light source and the second boundary light source.

10 . The vehicle signal lamp according to claim 1 , further comprising:
at least one of a reflective layer and a refusing layer formed on the plurality of concavo-convex surfaces of the second inner surface.

11 . The vehicle signal lamp according to claim 4 , wherein the at least one first light source is used as a light source for at least one of a tail lamp and a stop lamp.

12 . The vehicle signal lamp according to claim 4 , wherein the at least one second light source is used as a light source for at least one of a tail lamp and a stop lamp.

13 . The vehicle signal lamp according to claim 5 , wherein the at least one first light source is used as a light source for at least one of a tail lamp and a stop lamp.

14 . The vehicle signal lamp according to claim 5 , wherein the at least one second light source is used as a light source for at least one of a tail lamp and a stop lamp.

15 . The vehicle signal lamp according to claim 6 , wherein the at least one first light source is used as a light source for at least one of a tail lamp and a stop lamp.

16 . The vehicle signal lamp according to claim 6 , wherein the at least one second light source is used as a light source for at least one of a tail lamp and a stop lamp.

17 . The vehicle signal lamp according to claim 7 , wherein the at least one first light source is used as a light source for at least one of a tail lamp and a stop lamp.

18 . The vehicle signal lamp according to claim 7 , wherein the at least one second light source is used as a light source for at least one of a tail lamp and a stop lamp.

19 . The vehicle signal lamp according to claim 8 , wherein the at least one first light source is used as a light source for at least one of a tail lamp and a stop lamp.

20 . The vehicle signal lamp according to claim 8 , wherein the at least one second light source is used as a light source for at least one of a tail lamp and a stop lamp.
