Abstract

PURPOSE:To call attention to the following vehicle much more by providing a specific display of letters or the like at a part of the light untransmissible surface of a lens to cover the lamp. CONSTITUTION:A light transmissible film 4 is stuck to all the surface of the outer side of a lens 3, and at the outer side of the film 4, minute dots 5 (untransmissible parts) are formed evenly in a specific density by a printing. When the braking is not applied, the external light is reflected by colored layers 6 and 6a, and the driver in a following vehicle can recognize with eye the letters 7 classified with white and blue colors. And when the braking is applied, the majority of the strong projection light from a lamp 2 is transmitted between the dots, even though it is absorbed partially by the dots 5. As a result, the letters 7 of the dot pattern on the surface receives no influence, and the lens 3 is lighted in a red color functioning as an ordinary stop lamp. In other words, the letters 7 are extinguished suddenly following the braking, the following vehicle is given an attention depending on a sudden change of apperance, and a read-end collision can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a stop lamp used in vehicles such as automatic Φ.

(Prior Art) Automobile stop lamps generally have a light bulb inside a red-colored acrylic lens, which lights up when the vehicle is braking to issue a warning to following vehicles. There is.

(Problems to be Solved by the Invention) As described above, ordinary stop lamps are limited to those that simply light up in red to issue a warning to following vehicles.

The purpose of the present invention is to improve the general stop lamp so as to provide a further warning to following vehicles.

(Means for Solving the Problems) In order to achieve the above-mentioned object 1, the present invention provides a stop lamp that lights up when the vehicle is braking, in which a large number of non-transparent parts are minutely formed on the surface of the lens that covers the lamp. A predetermined density of 6 is applied almost uniformly to the lens, and a part of this non-transparent part (where a predetermined display such as letters etc. is made on the lens,
The outside is colored.

(Function) Therefore, with the above configuration, the predetermined display attached to the lens side can be visually recognized as is during normal driving, that is, when the lamp is not lit.

- On the other hand, when the lamp lights up due to braking, the powerful irradiation light from the °M bulb can pass between the dots, so the entire lamp lights up in red without being affected by the above display and functions as a normal stop lamp. Function.

(Embodiments) Examples embodying the present invention will be described in detail with reference to the drawings.

FIG. 11 shows one side of the rear combination lamps arranged on the left and right in the tail section of an automobile. Therefore, a stop lamp 1 is integrated here together with a rear turn jig and a rear turn lamp. The stop lamp 1 generally has a bulb 2 built into the lamp ring, and is covered with a red-colored acrylic lens 3 having light-transmitting properties.

In this example, a translucent film 4 whose inner surface is an adhesive surface is attached to the entire outer surface of the lens 3. On the outer surface of this film 4, fine drivers 1-5 (non-transparent areas) are uniformly printed at a constant density. However, each drum 1 is attached with a color (black in this example) having a high light absorption rate.

Further, a colored layer 6 is laminated on a part of each dot 5, so that the characters 7 of "'5rop" are displayed as a whole. @Color layer 6 has a color with a high repulsion rate (in this example, white)
is used, and external light is reflected by this colored layer 6 and is blocked from passing into the interior.

In the tree IIA, t, the color separation of characters represented by further laminating another colored layer 6a on the same dot 5F is also performed.

The stop lamp of this example is constructed as described above.

When the car is not braking, the light bulb 2 of the stop lamp 1 is not lit, and in this state, as shown in Figure 3, external light is reflected by the colored FiF 16.6a, so the first
As shown in the figure and FIG. 4, the driver of the following vehicle can visually recognize the letters 7 of "S T OP" which are color-coded in white and blue. 1 In this case, each dot 5 colored in black gives the character 7 ff fflt t, t a slightly blackish tint, making it stand out even more than the character 7t.

On the other hand, when the light bulb lights up during braking, as shown in FIG. ,
As shown in FIGS. 2 and 6, the lens 3 is illuminated in red without being affected by the letters 7 of the dot pattern on the surface, and functions as a normal stop lamp. That is, since the letters 7 of '5 TOP' suddenly disappear with braking, it is possible to warn the following driver based on the sudden change in appearance, thereby preventing a rear-end collision.

Although this example shows the case where the dots 5 are attached to the film 4, the dots 5 may be attached in a fine grid pattern. Further, in this example, a case where colored M6 and M6a are laminated is shown, but N1N may be used as long as it has a light-shielding property. Furthermore, the film 4 is not limited to the characters 7, and may include a combination of patterns, designs, etc. It is also possible to apply the dots 5 directly onto the lens, ie in this case a film is not necessarily required.

(Effects of the Invention) As is clear from the above description, according to the present invention, the letters, etc. attached to the surface of the lamp are visible as they are during normal driving, and when the lamp is turned on during braking, the letters, etc. suddenly disappear. Compared to the conventional technology, it is possible to further arouse the following vehicle's suffocation, contributing to safe driving.

Claims (1)

[Claims] In a stop lamp that lights up when a vehicle is braking, a large number of non-transparent parts are applied finely and almost uniformly with a predetermined density on the surface of the lens that covers the lamp, and some of these non-transparent parts are also attached on the lens. A stop lamp for a vehicle, characterized in that the outside thereof is colored so that a predetermined display such as characters is displayed on the outside.
