[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on examples with reference to the drawings. In FIG. 1, reference numeral 3A denotes a housing, and lenses 1A to 1H are attached to the entire circumference of the side surface of the housing 3A as shown in the figure. Is open. Also, inside the 3A housing, 2A, 2B, 2C, and 2D reflecting mirrors are attached to the side surface of the 3A housing at an angle of 45 degrees as shown in FIG.
From the center of the width of the side surface of the housing to the center of the adjacent width, the height of the housing is attached at four places, and the upper surface is covered with a 3D housing upper cover so as to prevent light from leaking. It is a thing. The lenses 1A to 1H are eight in order to explain the effect, and are partitioned by the reflecting mirrors 2A, 2B, 2C, and 2D in the housing 3A, so that 1A, 1B, 1C, and 1D. 1E and 1F, 1G and 1
Each H may be formed as one body.

Reference numeral 1A denotes a lens, and as described in the above claims, when the light of the automobile headlight enters the lens surface of 1A, the light of the headlight is colored, so that the light of the headlight becomes the lens of 1A. It is installed so as to be converted into color and lead to a 2A reflecting mirror. 2A is a reflector and 3A
It is mounted in the housing of the above by the method described above and
The direction of the light guided by the lens is converted by 90 degrees and guided to the adjacent 1H lens. Due to the above effect, the light of the headlight of the automobile enters from the lens of 1A and is guided to the lens of 1H, so that the lens of 1H emits surface light in the lens color of 1H. On the contrary, the light entering from the 1H lens is guided to the 1A lens through the opposite route described above, so that the 1A lens also emits the 1A lens color. Further, the remaining lenses 1B and 1C, 1D and 1E, 1F and 1G also have the same effect as described above, so that the lens colors are illuminated. However, when the lens is transparent, the color of the light from the headlight reaches the surface and illuminates the surface.

In FIG. 3, reference numeral 3B denotes a housing, and four square holes slightly smaller than the housing side area are provided on the four side surfaces of the housing 3B, and lenses 1A to 1H are provided on the entire circumference of the side surface of the housing 3B. It is attached as shown. Further, as shown in the figure, 6 optical fibers are connected to the adjacent lenses at an angle of 90 degrees inside the housing of 3B. Further, the inside of the 3B housing is partitioned into 5 crosses by a partition plate made of a material that does not transmit light, and the upper surface is covered with a 3D housing upper cover so as to prevent light from leaking. The lenses 1A to 1H are eight in order to explain the effect, and the lenses 3B
1A because it is partitioned by 5 partition plates in the case of
And 1B, 1C and 1D, 1E and 1F, 1G and 1H may be formed as one body.

Reference numeral 6 is an optical fiber for converting the direction of light. 1A to 1H are lenses. Explaining 1B and 1C among the above lenses, the lens of 1B has through holes and holes that do not penetrate alternately for attaching the 6 optical fibers. As described above, when the 6 optical fibers are through holes, Is exposed to the lens surface and is connected at a position inside the lens when it is not a through hole. The 1C lens is also processed in the same manner as above, and the opposite side of the 6 optical fibers connected to the 1B lens is connected. At this time, when the connection destination of one side of the optical fiber 6 is a through hole because of the light receiving side of 6A on the lens side of 1B, the opposite side is connected to a hole that is not penetrated because of the projecting side of 6B on the lens side of 1C. To do. By the above, when the light of the automobile headlight enters the 1B lens, the light becomes 1
It is converted into the lens color of B and reaches the light projecting side of 6B on the lens side of 1C from the light receiving side of 6A on the lens side of 1B of 6 optical fibers. At this time, when viewed from the lens side of 1C, the light reaching the light projecting side of 6B on the lens side of 1C looks like the lens color of 1B at the center of the optical fiber of 6.

Further, at the time of the above, light enters from the light projecting side of 6B on the lens side of 1B of the optical fiber of 6 and acts in the same manner as described above, and passes through the light receiving side of 6A on the lens side of 1C to reach the lens of 1C. Upon arrival, the light is converted to a lens color of 1C. At this time, when viewed from the lens side of 1C, 6 of the lens of 1C
The part of the optical fiber of 6A on the light receiving side is visible. When the light from the automobile headlight enters the 1C lens, the same effect is obtained by passing through the route opposite to the above case. As described above, when viewed from the lens side of 1C, both the light receiving side of 6A and the light projecting side of 6B appear to be bright, but the light projecting side of 6B is very effective. As described above, the larger the number of the attached 6 optical fibers, the closer to the surface illumination.
Further, the lenses of 1D and 1E, 1F and 1G, 1H and 1A also have the same effect.

In FIG. 5, reference numeral 3C designates a housing, and four partition holes, which are slightly smaller than the housing-side area, are formed on the four side surfaces of the housing of the 3C, and five partition plates made of a material that does not transmit light inside the housing. It is divided into crosses, and the top surface is covered with a 3D housing upper cover to prevent light from leaking, and transparent resin from 7A to 7D is attached to four locations inside the housing, which are divided into four rooms. Yes, the lenses 1A to 1H are attached to the surface of the transparent resin 7A to 7D along the surface of the square hole 4. Further, the lenses 1A to 1H are eight in order to explain the effect, and 1A, 1B, and 1C.
And 1D, 1E and 1F, 1G and 1H may be formed as one body. Further, the transparent resin of 7A to 7D may be colored on the transparent resin itself as described in claim 2 above. In the above case, since the transparent resin 7A to 7D is colored without mounting the lenses 1A to 1H, the same effect as described below can be obtained.

A partition plate 5 is a material that does not allow light to pass through the inside of the housing of 3C and divides it into four chambers to prevent light leakage. 7A to 7D are transparent resins, which are formed of a transparent material such as resin or glass into an L-shaped cube, and are treated such that light does not leak to the entire circumference of the L-shaped side surface, such as painting or plating. Alternatively, a film that does not transmit light is attached, and is processed so that light does not leak from other than both end faces of the L-shaped cube. Also, it is L-shaped in order to convert the direction of incoming light by 90 degrees. Lenses 1A to 1H are the same as the lenses 1A to 1H described in the description of FIG.
It may be the same as the lens of 1A to 1H described in the above description. As described above, the lenses 1A to 1H act in the same manner as the lenses 1A to 1H in FIG. 1 or FIG. 2, and the light entering from the lens 1A enters from the end surface of the transparent resin 7A on the lens side 1A. Since it is formed in an L shape, it is guided to the end surface on the lens side of 1H and the lens of 1H illuminates the surface. Also, the light coming in from the 1H lens goes through the opposite route to 1
The lens of A illuminates the surface. The remaining 1B, 1C and 1D
Similarly, the 1E, 1F, and 1G lenses also perform surface illumination. However, when the lens is transparent, the color of the light from the headlight reaches the surface and illuminates the surface.

In FIG. 7, the danger prediction reflector for road intersection is shown installed at the road intersection. 8 is a danger prediction reflector for road intersections. 9 is a center line. 10 is a road intersection. 11a is a car A. 11b is a car B. 12 is a headlight light A
Is. 12a is a headlight light B. Reference numeral 13 is the reflected light A. 13a is the reflected light B. 11 according to the above
