Claims (8)

1. Lenses that appear the same color as the car body from outside the vehicle, A vehicle lighting device comprising a light source that emits light that passes through the lens and is projected outside the vehicle, and a light generating unit that generates light of a predetermined color that is converted into light of a specified color when it passes through the lens.
2. The vehicle light fixture according to claim 1, wherein the light source emits light of the predetermined color.
3. The vehicle lighting device according to claim 2, wherein the light source is a multi-color LED.
4. The system includes a control unit that controls the multi-color LEDs, The vehicle lighting device according to claim 3, wherein the control unit controls the multicolor LED to emit light of a first predetermined color which is converted to a first predetermined color when it passes through the lens, and light of a second predetermined color which is converted to a second predetermined color when it passes through the lens.
5. The vehicle lamp according to claim 1, wherein the light generating unit is a light-transmitting member through which light emitted from the light source is transmitted, and the light color conversion member converts the color of the light emitted from the light source to the predetermined color.
6. The vehicle light fixture according to claim 5, further comprising a light-shielding member that blocks light directed toward the lens that is not converted to the predetermined color by the light color conversion member.
7. The vehicle lighting device according to claim 1 or 2, wherein the light generating unit comprises a light guide that distributes the light emitted from the light source toward the lens.
8. The aforementioned lens is, A lens body through which light emitted from the aforementioned light source passes, The vehicle light fixture according to claim 1 or 2, further comprising a body-colored film that covers the entire front or back surface of the lens body and is visible from outside the vehicle in the same color as the vehicle body.

Description

This invention relates to a vehicle lighting device. A vehicle light is known in which multiple rib-like protrusions are provided parallel to each other on the back surface of the lens, and a colored film of a different color from the lens is formed on the flat top surface of these protrusions, so that the lens surface appears to have a different color when illuminated and when not illuminated (see, for example, Patent Document 1). Also known is a turn signal equipped with an amber-colored light-emitting diode and a red-colored lens (see, for example, Patent Document 2). In the turn signal described in Patent Document 2, the light transmittance of the lens is set so as not to substantially change the peak wavelength of the light-emitting diode, in order to make the color of the light emitted by the light-emitting diode the same as the color of the light emitted by the turn signal.

The present invention will be described below in accordance with preferred embodiments. However, the present invention is not limited to the embodiments shown below, and can be modified as appropriate without departing from the spirit of the invention. Furthermore, in the embodiments shown below, some illustrations and descriptions of certain components are omitted. For details of the omitted technologies, publicly known or well-known technologies can be applied as appropriate, to the extent that they do not contradict the content described below. Figure 1 shows a vehicle C equipped with a vehicle light fixture 1 according to one embodiment of the present invention. As shown in this figure, the vehicle light fixture 1 is a headlight mounted on vehicle C. The outer lens 10 of the vehicle light fixture 1 is combined with an outer housing (not shown) so as to close an opening formed on the front surface of the outer housing. The outer lens 10 is positioned on the outside in the vehicle width direction of the grille G and, together with the grille G, constitutes the design of the front of vehicle C. Here, the outer lens 10 of the vehicle light fixture 1 is configured to appear the same color as the vehicle C's body when the vehicle light fixture 1 is not illuminated. For example, if the grille G and hood B of vehicle C are red, the outer lens 10 will appear red from the front of the vehicle when the vehicle light fixture 1 is not illuminated. In contrast, the vehicle light fixture 1 is configured to emit light that appears white, the standard color for headlights, towards the front of the vehicle when illuminated.
