Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to automobile lighting equipment such as front turn signal lamps.

<Prior Art> There is a tendency for recent automotive lighting to be more concerned with its exterior design.

However, for lamps that emit colored light when turned on, such as front turn signal lamps, the front lens must be colored, or the front lens must be made clear and a colored bulb must be used. Therefore, when looking at the lamp from the front when it is not lit, the presence of the colored bulb is visible through the front lens of not only the former lamp but also the latter lamp, which has the problem of spoiling the appearance of the lamp.

<Problems to be solved by the invention> The present invention was made in view of the above-mentioned problems of the conventional technology, and it can emit colored light with the required light distribution when turned on, and when it is not turned on, it can emit colored light with the required light distribution, and when it is not turned on, it can emit light with the required light distribution. To provide a lighting device for an automobile that appears in a similar clear color and can bring a sense of unity with other lighting devices.

<Means for Solving the Problems> The automotive lamp of the present invention that achieves the above object is composed of a lamp body, a reflector, a bulb, and a front lens, and a colored filter is provided around the outer periphery of the bulb. The front lens is formed by arranging and gathering cylindrical lens steps extending vertically, and the diffusion angle of the cylindrical lens steps is set from the center of the front lens. It is characterized by the fact that it becomes larger towards the periphery.

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

The automotive lamp A of the present invention is composed of a lamp body 1, a reflector 2, a bulb 3, and a front lens 4, as in the conventional case, and a colored filter (colored globe) is placed around the outer periphery of the bulb 3, or a colored bulb is used. The function color is emitted when the lamp is turned on.

The lamp body 1 is molded into a desired shape, a reflecting mirror 2 and a bulb 3 are installed inside the lamp body 1, and a front lens 4 is installed on the front side.

The reflecting mirror 2 has a parabolic reflecting surface 2a, and is molded into the same body as the lamp body 1 or separately.
It is installed inside the lamp body 1.

A colored filter (colored globe) colored red or amber is disposed around the bulb 3, or a colored bulb is used so that the bulb 3 can emit the functional color of the lamp A when the bulb 3 is lit.

The front lens 4 is molded in a transparent clear color, and has a cylindrical lens step 4a extending vertically on its inner surface.
is formed by forming an array set. As is well known, the cylindrical lens step 4a is formed into a substantially semicylindrical cross section.
The front lenses 4 are regularly arranged in the vertical and vertical directions when viewed from the front. At this time, the cylindrical lens step 4'a located at the center of the front lens 4, that is, just in front of the bulb 3, has a small diffusion angle and forms a narrow width, and as it approaches the periphery of the front lens 4 in the left and right direction, The diffusion angle of the cylindrical lens step 4''a is gradually increased to form a wider width.

<Effects of the invention> Since the automotive lamp of the present invention is constructed in this way, it can emit the functional color of the required light distribution when it is turned on, and when it is not lit, it appears to be the same clear color as the surrounding lamps, making it easy to blend in with other lamps. It can bring you a feeling. That is,
The diffusion angle of the cylindrical lens step located in the center of the front lens near the bulb is made small, and the diffusion angle increases toward the periphery, so when looking at the lamp when the lamp is not lit, the cylindrical lens of the front lens The diffusion effect of the step cancels out the presence of the colored bulb inside, and this tendency becomes more pronounced as the lamp is viewed from the front and side, making the front lens appear to have its original clear color, improving the appearance of the lamp. It is something.

[Brief explanation of drawings]

The drawings show an example of the implementation of the present invention, with FIG. 1 being a front view and FIG. 2 being a cross-sectional plan view. In the figure, A is an automobile lamp, 1 is a lamp body, 2 is a reflector, 3 is a bulb, 4 is a front lens, and 4a is a cylindrical lens step.

Claims (1)

[Scope of utility model registration request] In an automobile lamp comprising a lamp body, a reflector, a bulb, and a front lens, a colored filter is arranged around the outer periphery of the bulb or a colored bulb is used to emit colored light, and the front lens extends in the vertical direction. An automobile lamp characterized in that it is formed by arranging and gathering cylindrical lens steps, and the diffusion angle of the cylindrical lens steps increases from the center to the periphery of the front lens.
