Description

[Detailed description of the invention] <Industrial application field> The present invention relates to automotive lighting such as turn signal lamps, backlight lamps, stoplight lamps, tail lamps, or combination lamps made by combining these into one body. .

<Prior art> Modern automobile lighting equipment is seen as a part of the car body design, and there is a tendency to place emphasis on the exterior design, and there is a need for innovations that make the lighting equipment appear as a decorative item when not lit. There is.

However, conventionally, no automotive lamp has been provided that fully satisfies this requirement.

<Problems to be solved by the invention> The present invention has been made in view of these demands, and aims to provide at a low cost an automobile lamp that has a simple structure and satisfies the external design when the lamp is not lit. It is something.

<Means for Solving the Problems> The automotive lamp of the present invention which achieves the above object has a transparent outer lens coated and placed in parallel on the front surface of an inner lens formed with a prism that can obtain the required light distribution. The lens is colored to match the vehicle body color, and the outer lens is made thicker from the center to the periphery.

<Example> Hereinafter, an example of implementing the present invention will be described based on the drawings.

In the figure, 1 is an inner lens, 2 is an outer lens, and 3 is a bulb. These members are assembled to a lamp body 4 to constitute an automobile lamp.

The inner lens 1 is molded using a colorless transparent resin material such as glass or acrylic resin, and a Fresnel prism or a fisheye prism 5 is formed on the surface facing the bulb 3 to obtain the desired light distribution. color red or yellow as necessary.

The outer lens 2 is formed transparently using a transparent resin material such as glass or acrylic resin, and
Paint the car the same color or similar color to match the car body color. Then, the thickness of this outer lens 2 is adjusted to its center 2.
It is formed thicker from a to the peripheral portion 2b. In this case, from the center part 2a to the peripheral part 2
b may be formed in a discontinuous step-like shape as in the illustrated embodiment, or may be formed in a continuous curved shape. In addition, when the boundary line 6 between the thin center portion 2a and the thick peripheral portion 2b is formed into a substantially elliptical shape when viewed from the front as shown in the illustrated embodiment, when the lamp is formed into a horizontally elongated shape, it is possible to light the lamp. At times, the appearance of the lamp can be highlighted, and the appearance of the lamp can be further improved.

Thus, the inner lens 1 is installed in front of the bulb 3, and the outer lens 2 is installed in parallel in front of the inner lens 1 at an appropriate interval. Then, the light from the bulb 3 enters the inner lens 1, is controlled by the Fresnel prism or fisheye prism 5, and is distributed through the outer lens 2.

<Effects of the invention> Since the automobile lamp of the present invention is constructed in this way, when the lamp is turned on, the light from the bulb is distributed through the inner lens and the outer lens, and the lamp functions as an indicator.When the lamp is turned off, the lamp can match the color of the vehicle Due to the presence of the colored outer lens, the outer surface of the outer lens appears to be integrated with the vehicle body, and the lamp does not look like one, making the presence of the lamp less noticeable.

Moreover, the thickness of the outer lens is made thicker from the center to the periphery, so that when the lamp is viewed from the front, the tint colored on the outer lens becomes thicker from the center to the periphery. The color gradually becomes darker as the color changes, and therefore it is possible to have a subtle change in color, which can improve the appearance of the lamp and also improve the sense of unity with the vehicle body.

Therefore, the intended purpose can be achieved.

[Brief explanation of the drawing]

The drawing shows an embodiment of the automotive lamp of the present invention.
FIG. 1 is a schematic cross-sectional view, and FIG. 2 is a front view. In the figure, 1 is an inner lens, 2 is an outer lens, 2a is a center portion, and 2b is a peripheral portion.

Claims (1)

[Scope of utility model registration request] A transparent outer lens is coated and placed on the front surface of an inner lens that forms a prism that provides the desired light distribution, and the outer lens is colored to match the vehicle body color, and the thickness of the outer lens is varied from the center to the periphery. An automotive lamp characterized by a thicker wall as it gets closer to the top.
