Description

The present invention relates to a vehicle lamp.

Conventionally, as a vehicle lamp mounted on a vehicle, a combination of a light source such as a light emitting diode (LED) and a light guide such as an inner lens is known (see, for example, Patent Document 1 below). ).

In such a vehicle lamp, the light emitted from the light source enters the inside of the light guide from the base end of the light guide, and is repeatedly reflected inside the light guide until it reaches the tip of the light guide. The light is emitted to the outside of the light guide from the exit surface provided on the light guide. Thereby, it is possible to cause the light emitting surface of the light guide to emit light as a light emitting part of the vehicle lamp.

Patent No. 5441801

By the way, in the above-mentioned conventional vehicle lamp, when the light source is not turned on, the light that enters the inside of the light guide from the exit surface of the light guide due to irradiation with external light is repeatedly reflected inside the light guide. However, the light is guided to the exit surface side of the light guide and is emitted to the outside of the light guide.

Therefore, when a colorless and transparent light guide is used, the light that enters from the light guide's output surface is directly emitted from the light guide's output surface, so this light output surface is the same color as the outside light. It may appear shiny. Furthermore, the shape of the reflective cut provided on the light guide may be reflected on the exit surface of the light guide due to external light irradiation, resulting in poor appearance of the vehicle lamp when it is not lit.

The light-shielding part 24 is made of a black resin molded body integrally formed with the extension 5, and includes an extension part 5b extending from the back side of the extension 5 to a position facing the light-transmitting part 24.

In the vehicle lamp 1 of this embodiment, when the light source 3 described above is not lit, the light L' that has entered the inside of the light guide 4 is transmitted through the light transmitting part 23 by irradiation with external light, and then the light L' is transmitted through the light shielding part 23. 24 to block light.

In this case, the light L' incident from the output surface 16a of the light guide 4 is not directly output from the output surface 16a to the outside of the light guide 4. Therefore, the light emitting part is visually recognized as black (dark part), which is the same as the extension 5. Further, it is possible to prevent the shapes of the reflective cuts 14a, 15a, etc. provided on the light guide 4 from being reflected on the light emitting section due to external light irradiation.

As described above, in the vehicle lamp 1A of this embodiment, it is possible to improve the appearance when the turn lamp TRL is not lit.

Note that the extension 5 is not limited to the above-mentioned black color, and may be, for example, red. In this case, the light shielding part 24 becomes the same red light absorbing part 24 as the extension 5. The light absorbing section 24 absorbs the light L' that has passed through the light transmitting section 23 and develops a red color. Therefore, the light emitting section is visually recognized as the same red color as the extension 5. Therefore, in this case as well, it is possible to improve the appearance of the turn lamp TRL when it is not lit.
