Abstract

PURPOSE:To eliminate coloring of a clearance lens so as to improve the outward appearance thereof by making two sides of a lens attachment part to which the marker lens of the clearance lens is attached, light diffusive. CONSTITUTION:On two sides of a lens attachment part 10 mounted on a clearance lens 6, a crimp processing is applied or steps of small projections are formed so as to form light diffusive surfaces 20, 21 respectively. On the bottom surface of the lens attachment part 10, a through-hole is formed mating the marker part 12 of the marker lens 7. Accordingly, at the time when an outer light L6 injected into a lamp 1 through the marker lens 7 passes through the lens attachment part 10, it is diffused on the light diffusive surfaces 20, 21, while a reflection light L7 through the lens attachment part 10 is diffused on the light diffusive surfaces 20, 21 so that the outer and reflection lights are diffused into a faded color. Thus, the clearance lens 6 is colored slightly into the color of the marker lens 7, thereby it is possible to improve the outward appearance thereof.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides illumination for different functions at the same time for the front (or rear) and sides of a vehicle body using one bulb, such as a clearance/side marker lamp, etc. The present invention relates to a vehicle lamp suitable for application to.

[Conventional technology]

2. Description of the Related Art Conventionally, a clearance/side marker lamp (hereinafter abbreviated as a lamp) installed at a part of a corner of a vehicle body is constructed as shown in FIG. 4. That is,
This lamp 1 has a vehicle body width display function and a confirmation function from the side of the vehicle body with a single bulb 2. When installed on the front side of the vehicle body, it is placed adjacent to the outside of the headlight 4. A lamp body 3 is provided.

The hole body 3 includes a rear wall portion 3A whose inner surface forms a paraboloid of revolution reflection surface 5, and an inner wall portion 3B extending forward from the edge of the rear wall portion 3A on the side of the center of the vehicle body. It integrally has an outer wall portion 3C extending rearward from the outer edge of the vehicle body of the rear wall portion 3A substantially parallel to the side surface of the vehicle body A, and is open to the front side and the outer side surface of the vehicle body. A clearance lens 6 is formed to form a rounded lens that is curved so that these openings match the curvature of a part of the corner of the vehicle body.
It is covered with A fixing part 8 integrally protruding from the back of the periphery of six colorless clearance lenses is welded with a hot plate to the surface of the open end 9 of the lamp body 3, and a fixing part 8 is welded to the surface of the opening end 9 of the lamp body 3, and a fixing part 8 is fixed to the surface of the opening end 9 of the lamp body 3. A lens attachment portion 1o consisting of a substantially rectangular recessed portion is provided.

A marker lens T is fitted into this lens attachment part 10,
And it is ultrasonically welded. The entire marker lens 7 is colored amber (orange), and the recirculating flap portion 11
and a marker portion 12 are provided. The re-reflector portion 11 retroreflects the outside light Ll from the side of the vehicle body, which is incident at a substantially right angle to the marker lens γ, in the same direction as the direction of incidence of the external light Ll, and has a part that protrudes on a part of the back surface of the marker lens γ. A large number of triangular pyramidal retroreflective elements (example 1986-4) were installed.
(see Publication No. 2373). On the other hand, the marker part 12 is composed of a diffusing lens consisting of a large number of small convex lenses, and
It has a smaller area and is surrounded by the reflector part jIK. The bulb 2 is inserted into the lamp body 3 through a bulb insertion hole 14 provided in the rear wall 3A of the lamp body 3, and its filaments 2 & 1 are substantially aligned with the focal point of the paraboloid of revolution reflection surface 5. .

15 is a socket plug, and 16 is an end rubber.

In the lamp 1 having such a configuration, out of the light emitted from the bulb 2, there is a direct light L3 directed toward the front of the vehicle body, a reflected light L4 directly reflected on the paraboloid of revolution reflection surface 5, and a reflected light parallel to the optical axis directed forward. The inner surface of the inner wall 3B (the reflected light that directly roars and reflects diagonally forward) passes through the front part of the clearance lens 6 and exits to the outside, thereby displaying the vehicle body width. On the other hand, a portion of the light L2 directed toward the outside of the vehicle body is diffused by the marker portion 12 and emitted to the outside, thereby allowing confirmation from the side of the vehicle body, and the remaining light is transmitted to the marker portion 12 or the lens attachment portion 1 The light hits the back surface of ton and is reflected inward.

On the other hand, part of the external light from the side of the vehicle is L! is retroreflected by the re-reflector part 11 in the same direction as the incident direction, and another part of the light L6 passes through the marker part 12 and the lens attachment part 10 and enters the lamp 1,
The light hits the inner surface of the inner wall portion 3B and is reflected, and the illumination passes through the front portion of the clearance lens 6.

[Problem that the invention seeks to solve]

However, in such a conventional lamp 1,
As described above, the light L6 that passes through the marker lens γ and the lens attachment part 10 from the side of the vehicle body and enters the lamp 1 has the color of the marker lens γ.

That is, since the light L6 is colored amber, when this light L6 is reflected on the inner surface of the inner wall 3B and illuminates the clearance lens 6, what should be white when viewed from the front appears amber, and the clearance lens 6 There was a problem that the appearance was poor.

This also applies to a portion of the light Lz emitted from the lamp 2 and directed toward the outside of the vehicle body. That is, the light L7 that is emitted from the bulb 2 toward the outside of the vehicle body, passes through the lens mounting portion 10, and is reflected by the return flap portion 11 or the marker portion 12 is reflected by the inner wall portion 3B.
This is because the light hits the inner surface of the lens and is reflected again, illuminating and transmitting the front part of the clearance lens 6.

Therefore, the present invention solves the above-mentioned problems,
With an extremely simple configuration, the clearance lens is prevented from being colored by external light that passes through the marker lens from the side of the vehicle body and enters the lamp, as well as light that exits from the bulb, passes through the lens mounting part, and is reflected by the inner surface of the marker lens. It is an object of the present invention to provide a vehicular lamp that prevents light damage and improves appearance from the front.

[Means for solving problems]

In order to achieve the above object, the present invention covers the front and side openings of a lamp body that is attached to a corner of a vehicle body and opens toward the front and outside of the vehicle body with a clearance lens. A lens attachment portion is provided on the surface of the side surface, a marker lens colored in a predetermined color is attached to this attachment portion, and the front and back surfaces of the lens attachment portion are used as light diffusing surfaces.

[Effect]

In the present invention, the light diffusing surface provided on the lens attachment part is
It diffuses the external light that passes through the marker lens from the side of the vehicle body and enters the lamp, and the reflected light that comes out from the bulb, passes through the lens attachment part, and is reflected by the inner surface of the marker lens, and the color of this light is colored by the marker lens. Dilute the color.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 is a sectional view taken along the line I-I in FIG. 2, which shows an embodiment of the present invention applied to a clearance/side marker lamp, FIG. 2 is a front view, and FIG. 3 is a side view. Components and parts that are the same as those in FIG. 4 are designated by the same reference numerals, and their explanations will be omitted. In these figures, the front and back surfaces of the nine-lens attachment portion 10 provided on the clearance lens 6 are textured or steps consisting of small protrusions are formed to form a light diffusing surface 20.
．． It constitutes 21. Furthermore, a light-transmitting hole 13 is formed in the bottom surface of the lens attachment portion 10 in correspondence with the marker portion 12 of the marker lens 7. This prevents the light L2 that is emitted laterally from the bulb 2 and illuminates the marker part 12 from being absorbed inside the lens attachment part 10 when it passes through the lens attachment part 10, thereby realizing much brighter illumination. It is for the purpose of

Further, on the inner surface of the inner wall portion 3B of the lamp body 3, there is a sawtooth reflective surface 22, which is made up of a large number of triangular prism-shaped protrusions arranged in parallel in the optical axis direction, and whose slopes 22& are directed toward the lens mounting portion 10. It is formed. This reflective surface 22 is subjected to a reflective treatment such as vapor deposition of aluminum or application of white paint.

23 is a rim, and 24 is a set screw for fixing the clearance lens 6 to the lamp body 3.

The rest of the structure is the same as the conventional lamp shown in FIG.

According to the lamp 1 having such a configuration, when the external light L6 that passes through the marker lens 7 from the side of the vehicle body and enters the lamp 1 passes through the lens mounting portion 10, the external light L6 passes through the lens mounting portion 10. Since the light is diffused by the light diffusing surfaces 20° and 21, the color becomes faint and the light becomes diffused. Similarly, light is emitted from the bulb 2 toward the side of the vehicle body, and the marker lens γ
The reflected light L1 that hits the inner surface of the lens mounting part 10
When the light passes through the light, it is diffused by the light diffusing surfaces 20 and 21, so that diffused light with a blurred color arrives. However, even if these diffused lights illuminate the front part of the clearance lens 6 from the inside, the color will be pale and the color of the marker lens T will be slightly different from that of the conventional structure shown in FIG. The appearance of the clearance lens 6 is good only by being colored. However, in this embodiment, since the reflective surface 22 is provided on the inner surface of the inner wall surface 3B of the lamp body 3, the above-mentioned scattered light L7 is reflected in the direction of the lens mounting portion 10. Therefore, the amount of light directed forward and illuminating the front portion of the clearance lens 6 is reduced, and the appearance of the -layer clearance lens 6 is improved.

〔Effect of the invention〕

As explained above, according to the vehicle lamp according to the present invention,
In a lighting device that has a clearance function and a side marker function that simultaneously illuminates a clearance lens and a marker lens with a single bulb, the front and back surfaces of the lens mounting part provided on the side surface of the lens, which is provided on the side surface of the clearance lens. is a light diffusing surface, and the outside light that passes through the marker lens provided on the lens mounting part from the side of the vehicle body and enters the lamp, and the reflected light that is emitted from the bulb and is reflected by the inner surface of the marker lens are used as the light diffusing surface. Since it is configured so that it is diffused by the surface, although it is colored with the color of this diffused light hammer marker lens, the color is lighter by the amount of diffusion compared to a lamp with a conventional structure that does not diffuse.
Therefore, it is possible to reduce the coloring of the clearance lens and improve the appearance of the lighting device from the front.
