Description

[Detailed description of the invention] <Industrial field of application> The invention relates to automotive lighting, and more specifically, the invention relates to a lighting device for automobiles, in which an outer lens and an inner lens are installed in parallel,
This relates to automotive lighting equipment such as turn signal lamps and stop lamps that emit an amber color such as red or yellow when turned on.

<Prior Art> Conventional automotive lamps of this type have a problem in that the amber color when lit is visible even when the lamp is not lit, which impairs the appearance of the lamp or the vehicle body when the lamp is not lit.

<Problems to be solved by the invention> The present invention has been made in view of the above-mentioned problems in the past. The aim is to provide lighting equipment for

<Means for Solving the Problems> The automotive lighting device of the present invention that achieves the above object is an automotive lighting device in which an outer lens and an inner lens are installed in parallel, and a lattice-like lens step is formed on the inner surface of the outer lens. Colored inner lenses are arranged in parallel with each other separated by the focal length of the lens steps, and a colored line colored in white or the color of the vehicle body is formed on the surface of the inner lens in correspondence with the focal position of each of the lens steps. It is characterized by

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

The lamp of the present invention basically consists of a lamp body 1, a bulb 2 installed inside the lamp body 1, and an outer lens 3 and an inner lens 4 installed in the front opening of the lamp body 1, as in the conventional lamp.

The outer lens 3 has a large number of lattice lens steps 5 on its inner surface having the same shape, the same size, and the same focal length.
The inner lenses 4 are arranged in a regular cluster and are formed to be white and transparent, and an inner lens 4 is installed in parallel with the lens step 5 at a focal length R apart from the lens step 5 at an inner position of the outer lens 3. The image is focused on the surface 4a of the inner lens 4.

The inner lens 4 is coated with a red or yellow amber color so that it can emit amber color when the bulb 2 is lit, and a colored line 6 colored in white or the color of the vehicle body is attached to the outer lens 4 on the surface 4a on the side facing the outer lens 3. It is formed to correspond to the focal position F of each lens step 5 of the lens 3. When applying an amber color to the inner lens 4, it may be colored by mixing a coloring agent into the material when molding the inner lens 4, or by pasting a colored film on the front surface 4a, the back surface, or both the front and back surfaces of the inner lens 4. Alternatively, paint may be applied.

The colored line 6 is colored white or the car body color (including colors similar to the car body color), and is formed in a linear or dotted line shape corresponding to the focal position F of each lens step 5 formed on the outer lens 3. Become. That is, the colored line 6 is formed so that the images of each lens step 5 formed on the outer lens 3 are connected on the colored line 6 of the inner lens 4. This colored line 6 is formed by painting or printing.

Thus, when the light is on, the light from the bulb 2 is colored amber when it passes through the inner lens 4 and emits a predetermined amber color, and when the light is not lit, the light from each lens step 5 of the outer lens 3 is colored amber.
..., the color of the colored line 6 formed on the surface 4a of the inner lens 4 appears to be the white lens color or the vehicle body color.

In addition, 7 in the figure is a cover tube attached to the ventilation hole 8 of the lamp body 1. The cover tube 7 is made of a material such as sponge or sponge rubber, which expands when it contains water and returns to its original state when it dries, at least on its inner surface. If the cover tube 7 is formed in this way, water that attempts to enter the lamp body 1 through the cover tube 7 will be absorbed by the inner surface 7a of the cover tube 7, and at the same time, the inner surface 7a of the cover tube 7 will expand. This pinches the inner diameter, making it even more difficult for the fluid to penetrate. At this time, the inner surface 7 of the cover tube 7
The inner diameter of the cover tube 7 is set so that the inner diameter of the cover tube 7 is not completely blocked even if the tube a expands with water, and the air inside the lamp body 1 passes through the ventilation hole 8 and the cover tube 7. allow free circulation.

<Effects of the invention> Since the automobile lamp of the present invention is constructed in this way, it can emit a predetermined amber color when it is on, as in the conventional case, and when it is not on, it can emit a colored line formed on the surface of the inner lens through each lens step of the outer lens. The color of the lamp looks like a white lens color or the car body color, and it is possible to improve the appearance of the lamp or the car body when it is not lit. In particular, if the colored line is colored to match the car body color, the surface of the outer lens becomes the car body color when the light is off, making it possible to reduce the presence of the lamp and create a sense of unity with the car body.

Therefore, the intended purpose can be achieved.
