Description

[Detailed description of the invention] [Industrial application field] The invention is used by being attached to a vehicle such as an automobile.
In particular, the present invention relates to a lamp such as a turn signal lamp, which is provided with an inner lens that emits light in the color of the lamp and which prevents false lighting.

[Conventional technology]

Generally, as this type of lamp, including a rear combination lamp, the structure disclosed in Japanese Patent Publication No. 59-26082 is known. This known lamp has a structure in which non-transparent particles are mixed into a lamp lens of an emitting color, for example, amber color, or an uncolored clear lens is disposed in front of the lamp lens. ing. Non-translucent particles are mixed into the uncolored clear lens, taking into consideration the compatibility with decorative materials around the lamp.

[Problem that the invention attempts to solve]

In the conventional example, the idea is to mix non-transparent particles into the lens itself to blend in with the surroundings. If a non-light-transmitting material is mixed, a problem arises in that the illumination function of the lamp is inhibited, and it is practically impossible to mix the material to the extent that it changes the amber color. Therefore, there is a limit to the mixing of non-transparent particles in the lamp lens or inner lens, and the color of the lamp light, such as amber or yellow, cannot be changed significantly, and the color of the lamp light cannot be changed significantly. There remains a problem with the color balance.

[Means for solving problems]

The present invention provides, as a specific means for solving the above-mentioned problems, a lamp in which a light source is disposed within a housing, and an amber-colored inner lens and an outer lens with a cut necessary for light distribution are disposed. A transparent intermediate lens is disposed between the inner lens and the outer lens, and the intermediate lens is configured so that light from the outside is totally reflected in a portion corresponding to a range not necessary for light distribution, and the light from the light source is The present invention provides a vehicle lighting device characterized by a lens cut so that the lens faces downward, and in particular, for turn signal lamps installed at the corners of the vehicle body, parts unnecessary for light distribution are visible from the outside. By making the light color invisible and making the almost clear lens itself visible, for example, in the case of a white body, the amber color becomes less noticeable and the entire vehicle looks cleaner.

〔Example〕

Next, the present invention will be explained in more detail with reference to the illustrated embodiment.A is a turn signal lamp that is attached to a corner of a vehicle, and the lamp is a light bulb 2 that is attached as a light source approximately in the center of a housing 1.
, an inner lens 3 of, for example, amber color, which is the color of the lamp light, a transparent outer lens 4 attached to the opening of the housing 1, and a transparent intermediate lens disposed between the inner lens 3 and the outer lens 4. It is composed of a lens 5.

The amber-colored inner lens 3 is disposed to completely cover the light bulb 2, and the outer lens 4
A lens cut 4a is provided to determine the light distribution as a lamp.

Since the intermediate lens 5 is a transparent lens, simply disposing it between the inner lens 3 and the outer lens 4 does not have any meaning, but it is possible to process a part of the intermediate lens 5. As a result, the light distribution state is changed and a part of the amber inner lens 3 is no longer visible from the outside. In other words, the lamp A that is attached to the corner of the vehicle body can be substantially divided into a range X that is necessary for light distribution and a range Y that is not necessary for light distribution, and the range Y that is not necessary for light distribution is the side surface of the vehicle body. Needless to say, it is located in Therefore, the intermediate lens 5
A prism cut 5a is formed on the inside of a portion corresponding to a range Y that is not necessary for light distribution.As shown in FIG. A prism cut is applied so that all the light b emitted from the light bulb through the inner lens 3 is directed downward.

Incidentally, in a portion corresponding to the range X necessary for light distribution, the intermediate lens 5 may be simply transparent, or may be cut in a predetermined manner in relation to the outer lens 4 for proper light distribution.

The intermediate lens 5 processed in this way is disposed between the inner lens 3 and the outer lens 4 to constitute a lamp A, and when this lamp is attached to a white body, for example, the human eye who looks at the lamp All external light entering from the eye level position is totally reflected by the intermediate lens 5, so at this position, the amber color of the inner lens 3 is not visible at all, and the clear outer lens 4 is visible. This creates an integrated, clean appearance without causing any discomfort in terms of color balance. In particular, the position where the amber color of the inner lens 3 is visible is through the prism cut 5a of the intermediate lens 5, so it is only visible when looking up at the lamp from below along the downward light b. It is almost unthinkable to look at the exterior of the car. Therefore, in the portion corresponding to the range Y that is not necessary for the light distribution of the lamp, the amber color of the inner lens 3 can be prevented from being seen by simply performing a predetermined process on the intermediate lens 5, thereby creating a sense of unity between the lamp and the vehicle body. It is possible to do so.

In addition, the amber-colored inner lens 3 is the same as the light bulb 2.
Since it is not located on the back side of the outer lens 4, that is, on the opening side of the housing 1, external light may enter the lamp through the outer lens and cause the reflection surface 1a of the housing 1 to Even if the inner lens 3 is reflected and taken out to the outside,
Colored light such as amber is not emitted to the outside, so false lighting cannot occur.

[Effect of idea]

As explained above, the vehicle lamp according to the present invention includes a transparent intermediate lens disposed between an inner lens colored in a luminous color and an outer lens provided with a lens cut necessary for light distribution, and the intermediate lens The lens is cut so that external light is totally reflected in areas that are not necessary for light distribution, and the light from the light source is directed downwards, so that when the lamp is turned on, Not only can the function be fully demonstrated without causing problems such as light blocking or dimming, but also the presence of the intermediate lens allows the lamp installed at the corner to be seen from the side along with the vehicle body. The coloring of the installed inner lens is not visible, and especially on a white car body, only the clear outer lens is visible, eliminating any sense of incongruity with the car body and creating an integrated clean appearance. It has various excellent effects.
