Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a novel vehicle reflector. More specifically, an object of the present invention is to provide a reflector for a vehicle that allows light from a light source to be used more efficiently and that has a better appearance.

[0002]

2. Description of the Related Art A vehicle lamp, for example, a signal light for an automobile, retroactively reflects light from a succeeding vehicle even when it is not lit, so that a driver of the succeeding vehicle recognizes the existence of the vehicle, thereby preventing a rear-end collision or the like. In order to prevent this, a reflector provided with a retroreflective element is often provided.

FIG. 10 shows an example a of a vehicular lamp using such a reflector.

[0004] Reference numeral b denotes a lamp body, and bulbs c and c are attached to a rear portion thereof. d is a lens covering the front opening of the lamp body b. A reflector f provided with a large number of retroreflective elements is fitted in a concave portion e provided substantially at the center of the lens d.

However, in such a vehicle lamp,
The lighting light g of the light bulbs c and c is emitted forward through the lens d, and the external light h is retroreflected in the direction of the light source by the retroreflective element of the reflector f.

[0006]

By the way, in the conventional vehicular lamp a, when the lens d is viewed from the front when the bulbs c are lit, the reflector f of the lit light g of the bulbs c is c. The light applied to the back surface of the light emitting device is not emitted to the outside and becomes useless light, and the effective use of the lighting light g cannot be achieved.

When the light bulbs c and c are not lit,
The shapes of the lens elements of the reflector f and the lens d around the reflector f are clearly different. Further, even when the reflector f is turned on, light is not emitted from the reflector f. Because the brightness with the surroundings is extremely different,
There is a problem that the sense of unity as a lamp lens is impaired and the appearance is deteriorated.

[0008]

In order to solve the above-mentioned problems, a vehicle reflector according to the present invention is provided with a retroreflective section having a large number of retroreflective elements formed therein, and transmitting light from a light source to the outside. The light-transmitting portion is divided into a plurality of regions, in which a region where the retroreflective element is formed and a region where the transmissive element for transmitting light are formed are alternately formed in a strip shape. It is arranged on the front side.

[0009]

Therefore, in the vehicle reflector according to the present invention, the light emitted from the light source to the back surface of the reflector is emitted to the outside from the light transmitting portion, so that the light of the portion different in brightness from the lens is obtained. Since the area is reduced, the sense of unity as a lamp lens is improved, the appearance is good, and the wasted light is reduced, so that the light can be used effectively.

Further, since the retroreflective element is arranged over the entire surface of the reflector, external light is reflected in a wide range, visibility is improved, and safety is enhanced.

A portion of the outer lens 13 which is slightly leftward when viewed from the front of a portion corresponding to the front of the lamp chamber 3 is formed with a horizontally long rectangular recess 14 which opens forward. ing.

Reference numerals 15 and 16 denote inner lenses made of a synthetic resin. Reference numeral 15 denotes a transparent red color, which is formed in a shape which covers the front surface of the lamp chamber portion 3, and 16 denotes a colorless and transparent shape which covers the front surface of the lamp chamber portion 4.
The right end of the inner lens 15 is provided with a protruding wall 15a.

On the back surfaces of the inner lenses 15 and 16, there are provided a number of appropriate optical elements, for example, a large number of square fish-eye lens elements as viewed from the front.

Thus, the inner lens 15 is attached to the lamp body 2 so that the protruding wall 15a is fitted into the installation groove 2b filled with the sealant, and covers the front surface of the lamp chamber 3. The outer lens 13 has an inner lens 16 integrally attached by ultrasonic welding at a position corresponding to the front surface of the lamp chamber 4 inside the outer lens 13, a peripheral wall 13 a of the outer groove 13 in the installation groove 2 a, and a sealing material in the installation groove 2 a. Is attached to the lamp body 2 by being fitted in a state in which it is filled.

Numeral 17 is a reflector which is rectangular in a horizontal direction when viewed from the front. A plate-shaped main portion 18 and a peripheral wall 19 projecting rearward from the periphery of the main portion 18 are colored and transparent, for example, red transparent. And formed integrally with the synthetic resin.

Reference numeral 20 denotes a substantially triangular pyramid formed on the rear surface of the central portion of the main portion 18 of the reflector 17 by combining three square surfaces over approximately one third of the length of the reflector 17 in the left-right direction. And a number of well-known retroreflection elements 21, 21,... Formed in a hexagonal shape when viewed from the front of the reflector.

Then, both sides 22,
Reference numeral 22 denotes a vertically elongated strip-shaped area 22a, 22a,.
. And 22b, 22b,... Are light-transmitting portions provided alternately in large numbers.

That is, the regions 22a, 22a,.
.. Are areas in which retroreflective elements 21, 21,... Similar to those formed in the retroreflective section 20 are provided in a line in the vertical direction, and areas 22b, 22b,.
.. Are areas where transmission elements 23, 23,...

The area 22b has a greater width as it is positioned closer to the left and right ends of the reflector 17.

The transmission elements 23, 23,...
Is obtained by cutting a triangular pyramid-shaped top 21a, which is a portion for retroreflecting light from the retroreflective element 21, as shown in FIG. As the surface 23a, external light is not retroreflected, and light from the light source can be transmitted.

With the above configuration, the reflector 17
When viewed from the front, the retroreflective elements 21 are distributed over the entire surface of the reflector such that the density of the formation of the retroreflective elements 21 is high in the central portion and becomes coarser toward the left and right ends, and the other portions have On the contrary, the formation density of the transmission element 23 is
7 are arranged so as to be denser toward both ends, so that light from the light bulbs 8 and 9 at the rear can be emitted to the outside.

The reflector 17 is fitted into the concave portion 14 of the outer lens 13 and is integrally connected to the outer lens 13 by ultrasonic welding.

Reference numeral 24 denotes a substantially transparent shape, colored transparent,
For example, it is colored amber, and the reflection concave portion 11 of the lamp room portion 4 is formed.
This is a synthetic resin colored filter shaped to cover the front surface of, and has screw holes 25 formed in the outer peripheral portion.

The colored filter 24 is provided on the boss 2 formed on both sides of the reflection recess 11 of the lamp body 2.
The screws 6 and 26 are attached to the lamp body 2 by screws inserted through the screw holes 25 and 25.

As described above, in the rear combination lamp 1 using the vehicle reflector 17 of the present invention, the outer lens 13 to which the inner lenses 15 and 16 and the reflector 17 are attached is attached to the lamp body 2. As a result, the light transmitting portions 22, 22 of the reflector 17 are changed to the reflecting concave portions 5, 6, respectively.
And the retroreflective portion 2
0 is located between them, the lamp chamber 3 functions as a tail and stop lamp, and the lamp chamber 4 functions as a turn signal lamp.

Therefore, in the rear combination lamp 1, the reflector 17 not only includes the retroreflective portion 20 but also the translucent portions 22 and 22 retroreflect external light, so that the reflector 17 is wide over the entire surface of the reflector 17. The area functions as a reflex reflection effective surface, and when the light bulbs 8 and 9 are turned on, not only the outer lens 13 but also the light illuminated on the back surface of the reflector 17, which is originally ineffective, is emitted from the translucent portions 22, 22. And the area shining by the light from the bulbs 8 and 9 of the outer lens 13 is also widened, thereby enabling effective use of originally wasted light and improving visibility. It has a synergistic effect of increasing the safety and thus the safety.

Further, since the light bulbs 8 and 9 are located immediately below the light transmitting portions 22 and 22 of the reflector 17, light around the light bulbs 8 and 9 having a high light flux density is Since the light is inevitably dimmed to pass through one more lens than the other parts, that is, the inner lens 15 -the outer lens 13 -the reflector 17, and is emitted to the outside, the degree of luminosity of the outer lens 13 is reduced. Be uniformed.

Further, the reflector 17 includes the retroreflector 2
0 and the light-transmitting parts 22 and 22 are divided into three parts.
2 are retroreflective elements 21, 21,... And transmissive elements 23,
23,... Are each formed in an upper and lower band shape.
2a and 22b are formed alternately, and the width of the region 22b where the transmissive element is formed is closer to the left and right ends of the reflector 17, the wider the region is formed. 17 are arranged so that the center portion is dense and the end portions are coarse, in other words, the density of the transmission elements 23 is increased toward the both end portions of the reflector 17. There is also an effect that the appearance gradually improves without any unnaturalness by gradually moving to the entire transmission portion around the reflector 17.

17A shows a modified example of the vehicle reflector 17 of the present invention.

The only difference between the reflector 17A and the reflector 17 is the shape of the transmissive element of the light-transmitting part. The description is omitted by attaching the same reference numerals.

That is, as is apparent from FIGS. 8 and 9, the regions 22a, 22a,.
1 is an area provided in one row in the vertical direction, and
The regions 22b, 22b,... Are regions where the transmissive element 27 is provided over one surface of each predetermined width.

The transmission element 27 is a fisheye lens element having a hexagonal outline when viewed from the front of the reflector 17A.

Thus, with the above configuration, the reflector 17A
When viewed from the front, the retroreflective elements 21 are arranged over the entire surface of the reflector such that the density of formation of the retroreflective elements 21 is high at the center and becomes coarser toward the left and right ends, and the other portions are transparent. The element 27 is arranged, and conversely, the element is arranged so that the density of the transmission element 23 becomes denser toward both ends of the reflector 17.

The reflector 17A is also fitted into the concave portion 14 of the outer lens 13, and is integrally connected to the outer lens 13 by ultrasonic welding.

Accordingly, the reflector 17A according to the above-described modification example
Since the shape of the retroreflective element 21 and the transmissive element 27 are the same when viewed from the front of the reflector 17A, that is, both are hexagonal, the light-emitting state of the light bulbs 8 and 9 is turned off. , These elements are seen integrally, and further, these transmission elements 27 are also arranged around them, and the square fish-eye lens elements viewed from the front of the outer lens 13 are both fish-eye lens elements. Shines in the same manner, so that they can be seen integrally and do not feel uncomfortable.

In the above embodiment, the reflector is formed separately from the outer lens. However, the reflector in the present invention may be formed integrally with the outer lens by a so-called multicolor molding method. .

As is apparent from the above description, the vehicle reflector according to the present invention is a vehicle reflector disposed in front of a light source, wherein the retroreflector includes a large number of retroreflective elements. And a light-transmitting portion that transmits light from a light source and emits the light to the outside. Further, in the light-transmitting portion, regions provided with a retroreflective element and a light-transmitting element that transmit light are alternately formed in a band shape. In which a large number is formed.

Therefore, in the vehicle reflector of the present invention,
Since not only the retroreflective portion but also the light transmitting portion retroreflects the light from the outside and shines over a wide area of the entire reflector, visibility and safety are improved.

Further, in addition to the original function of the retroreflector, a part of the reflector can be used as a lens for emitting the light of the light source to the outside, so that the light from the light source is not wasted and the light is effectively used. can do.
