Description

[Detailed Description of the Invention] The present invention relates to an improvement of a vehicle lamp.

Conventionally, among this type of lighting equipment, there is a so-called high-contrast lamp, which has the effect of preventing false lighting by reducing sunlight entering the lighting equipment (see Japanese Patent Application Laid-Open No. 156379/1983). ). Furthermore, as shown in Fig. 1, the structure is that a convex lens cut is provided on the back surface of an inner lens b provided at the back of an outer lens a, and the surface of the inner lens b allows light that is focused by the convex lens cut to pass through. A portion c and a light shielding portion d that reflects sunlight are provided. The light shielding part d was formed by hot stamping or the like on the plane between the transparent parts c.

However, in the above-mentioned conventional structure, when the light shielding part is made of bright white or colored hot stamp of aluminum photo-selective color, the surface of the light shielding part is flat and sunlight strongly reflects and shines brightly. The drawback was that even when the bulb was on, the emitted light was not noticeable, reducing visibility to oncoming cars, following cars, and pedestrians.

The purpose of this invention is to solve the above-mentioned conventional drawbacks, and its gist is that an outer lens and an inner lens are attached to the front of the lamp body, and a convex lens cut is attached to the back of the inner lens. and a light shielding part that is located between the transparent part, protrudes forward, and is covered with an opaque layer. , the protruding end surface of the light shielding portion is directed downward.

Next, the present invention will be explained in detail based on an embodiment shown in FIGS. 2 and 3.

The light fixture 1 has an outer lens 3 on the front of the light fixture body 2.
and an inner lens 4 are attached. A convex lens cut is provided on the back surface of the outer lens 3. A convex lens cut is also provided on the back surface of the inner lens 4, and the cut pitch is larger than that of the outer lens 3. As shown in FIG. 3, a transmitting portion 5 is provided on the front surface of the inner lens 4 to transmit the light focused by the convex lens cut on the rear surface. The transparent part 5 is cut into a concave shape with the same pitch as the cut pitch of the convex lens cut in the inner lens 4 and with a width shorter than one cut width (B<A), and is provided in the housing 20. Parabolic reflector 2
2 or the light emitted from the light bulb 21, which becomes substantially parallel light rays through a Fresnel lens (not shown) provided on the front surface of the light bulb 21, is focused by a convex lens cut, and becomes parallel light rays again at this concave transmitting portion 5. and enters the outer lens 3. The parallel light beams incident on the outer lens 3 are diffused vertically and horizontally by a convex lens cut provided on the outer lens 3.

6 is a light shielding part, and the light shielding part 6 is between the above-mentioned transparent parts 5.
(C≧B), a rib 7 that protrudes forward and has a tip end face 70 inclined downward is integrally formed, and the rib 7 is coated with an impermeable layer 8 made of colored paint or the like.

Therefore, according to the present invention, since the light shielding part suppresses the incidence of outside light such as sunlight into the lamp, there is an effect of preventing false lighting, and since the end surface of the light shielding part is oriented downward, The leading edge reflects external light downwards, preventing it from dazzling oncoming cars and pedestrians. Furthermore, when the lights are on, the colored light of the inner lens is emitted, and when the lights are off, the colors applied to the light shielding parts are visible, so when the lights are off, the color tone of the front and rear of the vehicle, including the lights, can be unified. can improve the appearance of The concavely cut transmission section allows the light incident on the inner lens to pass through as parallel light, and has excellent practical effects such as less loss of light emitted from the light bulb due to the light shielding section.
