  However, in the case of these lamp-equipped vehicles, each lamp is visible only from one of the front and rear of the vehicle, so in order to obtain the lighting effect of the lamp on the front and rear sides of the vehicle The front and rear lamps must be installed in the vehicle. For this reason, there is a concern that the number of lamps installed in the vehicle increases, leading to a rise in manufacturing cost and an increase in weight. Further, in the above-mentioned vehicle equipped with a lamp body, the lamp body has no function of recognizing the vehicle body itself (vehicle width, etc.).

  For small vehicles, etc., when a vehicle with a high driving viewpoint such as a large truck or trailer (hereinafter referred to as a “high-viewpoint vehicle”) approaches from behind, the driving of the high-viewpoint vehicle in which the vehicle body looks closely at the front. Visibility tends to decrease by entering below the visual field of the person. In such a situation, the alerting effect of a lamp such as a brake lamp provided at the rear end of the vehicle body is not always sufficient. For this reason, at present, it is desired to devise means capable of causing a driver of a high-viewpoint vehicle to recognize the vehicle with certainty.

  In view of this, the present invention provides a vehicle equipped with a lamp that can reduce the number of parts and enhance warning by lighting the lamp so that lighting can be reliably recognized in front and rear of the vehicle with a common lamp. It is something to try.

As means for solving the above-mentioned problems, the invention according to claim 1 is directed to the front of the vehicle from the top (for example, top T in the following embodiment) of the vehicle roof (for example, the roof 4 in the embodiment described later). A lamp having a light irradiation surface (for example, a light irradiation surface 12a in an embodiment described later) at least on an upper surface side on a roof front inclined surface (for example, a roof front inclined surface 6 in the embodiment described later) inclined downward. A body (for example, a lamp unit 9 in an embodiment described later) is installed.
As a result, the light emitted from the light irradiation surface of the lamp body is visible from the front side of the vehicle, and from the rear side of the vehicle, the light irradiation surface is hidden at the top of the vehicle roof from the driving field of view of the following vehicle with a high viewpoint. It becomes visible when the conditions are not met.

At the above time, it was made visible.
As a result, when a vehicle such as a large truck whose driver's seat viewpoint height is equal to or higher than the set height approaches from behind, the light emitted from the lamp body is visually recognized from the following vehicle. In addition, when a vehicle whose driver's seat viewpoint height is less than the set height approaches from behind, the light irradiation surface of the lamp is hidden by the top of the vehicle roof and is not visible from the following vehicle.

In addition, the invention described in claim 3 is the vehicle equipped with the lamp according to claim 1 or 2, wherein the lamp is configured to irradiate light rearward with respect to the vehicle forward direction (for example, A first irradiation unit 21 in an embodiment described later and a second irradiation unit (for example, a second irradiation unit 22 in an embodiment described later) for irradiating the front side with light are provided.
Thereby, it becomes possible to irradiate light efficiently from each irradiation part corresponding to back and front of a vehicle.

According to a fourth aspect of the present invention, in the lamp-equipped vehicle according to any one of the first to third aspects, the irradiation light of the first irradiation unit and the irradiation light of the second irradiation unit are made different from each other. I did it.
Specifically, for example, the first irradiation unit may blink with red light, while white or amber light may be emitted from the second irradiation unit. Thereby, the function and visual effect which are different by the visual recognition from the vehicle front side and the visual recognition from the back side can be given.

The invention according to claim 5 is the vehicle equipped with the lamp body according to any one of claims 1 to 4, wherein the lamp body has different irradiation light intensities depending on a viewing angle in a vertical direction from the rear of the vehicle body. Polarizing means (for example, a polarizing lens 30 in an embodiment described later) is provided.
In this case, for example, the irradiation light intensity becomes weak in the range where the peeping angle from above the light irradiation surface on the upper surface side of the lamp body exceeds the set angle, and when the peeping angle is within the set angle, the irradiation light intensity is reduced. It is possible to set the polarization means to be strong. When the polarizing means is set in this way, only when the high-viewpoint vehicle approaches the set distance range from the rear, the light with high irradiation intensity is visually recognized by the driver of the following vehicle.

The portion with cross hatching in FIG. 7 indicates the region of the lamp unit 9 that is visually recognized at this time.
However, the set height H is set to a value larger than the average viewpoint height when the user gets on the driver's seat of the ordinary vehicle. Accordingly, when the succeeding vehicle approaches the lamp-equipped vehicle 1 to a predetermined distance L, if the succeeding vehicle is a normal vehicle, the light irradiation surface 12a of the lamp unit 9 is not visually recognized by the driver of the succeeding vehicle, If the vehicle is a high-viewpoint vehicle such as a large truck, the light irradiation surface 12a is surely visually recognized by the driver of the following vehicle.

  Further, as described above, the lamp unit 9 is integrally provided at the front end portion of the roof molding 8, but the electric cable 13 drawn out from the circuit mounting portion 11 of the lamp unit 9 is placed inside the roof molding mounting groove 7. Along the top portion T in the same mounting groove 7, the side wall 14 is penetrated and drawn into the vehicle interior. A through hole 15 for drawing out a cable is formed in the side wall 14 of the roof molding mounting groove 7, and an electric cable 13 is fitted into the through hole 15 via a grommet 16.

  Since this lamp-equipped vehicle 1 is configured as described above, when the large truck 3 approaches within a predetermined distance L from behind as shown in FIG. 1 with the lamp unit 9 lit, the driver of the large truck 3 The lighting of the lamp unit 9 on the roof front inclined surface 6 is noticeable in the field of view, and it is possible to strongly alert the following large truck 3 by the lighting of the lamp unit 9. In particular, in large trucks 3 where the driver's viewpoint is higher than the roof of a normal vehicle, the line of sight goes to the rear lamp, etc. of the vehicle one vehicle ahead beyond the roof of the previous vehicle. In the vehicle 1, since the lamp unit 9 is disposed at the front end portion of the roof 4 that is positioned within the driver's line of sight i, the driver behind the vehicle is surely recognized by the lighting of the lamp unit 9. be able to.

  Further, in the case of this lamp-equipped vehicle 1, the lamp unit 9 is disposed on the roof front inclined surface 6 inclined forward from the top T of the roof 4, and the front and upper surfaces of the lamp unit 9 can be visually recognized from the vehicle front side. Therefore, the lighting of the lamp unit 9 in the high place (roof 4) can be reliably recognized from the front side of the vehicle. Therefore, the presence of the lamp-equipped vehicle 1 can be surely recognized by a preceding vehicle, an oncoming vehicle, a pedestrian, and the like.

Furthermore, in the lamp-equipped vehicle 1 according to this embodiment, since the lamp unit 9 is mounted in the roof molding mounting grooves 7 on both sides of the roof 4, the lamp unit 9 does not protrude greatly on the roof 4 after the mounting. The appearance quality of the lamp can be improved and the roof molding mounting groove 7 can be used as it is when the lamp unit 9 is mounted. Furthermore, the electric wiring of the lamp unit 9 can be easily performed in the roof molding mounting groove 7.
In the case of this embodiment, the electric cable 13 of the lamp unit 9 is extended to the vicinity of the top portion T of the roof 4 along the roof molding mounting groove 7, and is drawn out into the vehicle interior in the vicinity of the top portion T. It is possible to more advantageously prevent rainwater or the like from entering the back side of the roof 4 through the through-hole 15 for drawing out.

  Further, in this lamp-equipped vehicle 1, the lamp unit 9 is formed integrally with the roof molding 8 so that the outer surface of the lamp unit 9 is substantially flush with the outer surface of the roof molding 8. Design performance is improved, running resistance is reduced, and wind noise during running is prevented.

By the way, in the lamp-equipped vehicle of this embodiment, the frontmost lamp 10a of the lamp unit 9 is mainly used for front irradiation, and the remaining three lamps 10b to 10d are used for rear irradiation. However, as shown by the phantom lines in FIG. 4, a partition wall 20 is further installed in the lamp unit 9, a first irradiation portion 21 for rearward irradiation on the rear side of the partition wall 20, and a front side of the partition wall 20. You may make it divide clearly into the 2nd irradiation part 22 for forward irradiation.
Thus, when it divides clearly into the 1st irradiation part 21 and the 2nd irradiation part 22, irradiation efficiency can be improved by installation of the reflector etc. which have directivity, and, thereby, the visibility can be improved further.

Further, when the lamp unit 9 is divided into the first irradiating unit 21 and the second irradiating unit 22 as described above, the color and intensity of light emitted from the irradiating units 21 and 22, the light emission pattern, and the like are changed. Anyway. For example, in the above embodiment, the lamps 10a to 10d of the lamp unit 9 are uniformly lit, but the lamp 10a of the first irradiating unit 21 is lit uniformly and the lamp of the second irradiating unit 22 is lit. You may make it blink 10b-10d.
In this way, when the color, intensity, light emission pattern, etc. of the light of the first irradiating unit 21 and the second irradiating unit 22 of the lamp unit 9 are made different, the front side of the vehicle while being one lamp unit 9. Different functions and visual effects can be provided for visual recognition from the rear and visual recognition from the rear side. Therefore, in this case, it is possible to reduce the number of parts and improve the design as compared with the case where a plurality of types of single-function lamp units 9 are installed.

Next, another embodiment of the present invention shown in FIG. 8 will be described.
The lamp-equipped vehicle 101 of this embodiment is the same as the above embodiment in the manner of installing the lamp unit 109 with respect to the roof 4, but the structure and function of the lamp cover 112 portion of the lamp unit 109 is the above embodiment. Different from the ones.
That is, the lamp cover 112 of this embodiment is provided with the polarizing lens surface 30 (polarizing means) so that the irradiation light intensity varies depending on the viewing angle from the outside, and the peeping angle behind the vehicle body from above is the set angle α˜. In the range of β, almost all of the irradiated light is transmitted, and when the viewing angle exceeds β, most of the irradiated light is blocked by the polarizing lens 30.

In the case of the lamp-equipped vehicle 101 employing the lamp unit 109, when a high-viewpoint vehicle such as a large truck approaches from the rear, the lamp unit 109 from the high-viewpoint vehicle is viewed after the lamp unit 109 is visually recognized from the high-viewpoint vehicle. Until the peeping angle 109 becomes equal to or less than β, light with low irradiation light intensity is visually recognized by the driver of the high-viewpoint vehicle by the action of the polarizing lens 30. When the high-viewpoint vehicle approaches the luminaire-equipped vehicle 101 more than a certain level, and the peeping angle of the lamp unit 109 from the high-viewpoint vehicle is in the range of the set angles α to β, the irradiation light intensity is large. Accordingly, the light is visually recognized by the driver of the high-viewpoint vehicle. Therefore, in the lamp-equipped vehicle 101, the irradiation light intensity of the lamp unit 109 increases stepwise as the high-viewpoint vehicle approaches the lamp-equipped vehicle 101. When approaching a certain level or more, the driver of the high-viewpoint vehicle can be strongly alerted by the light from the lamp unit 109 having a high irradiation light intensity.

  Here, the irradiation light intensity is changed according to the viewing angle by the polarizing lens 30 provided in the lamp unit 109. However, the color of the transmitted light is changed according to the viewing angle, or the viewing angle from above. However, when the set angle exceeds, the irradiation light may be completely blocked.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary. For example, in the above embodiment, the lamp body (lamp units 9 and 109) is described as being turned on by a switch operation at the driver's seat in the above embodiment, but the lamp body is interlocked with the depression operation of the brake pedal. Then, it may be turned on. In the above embodiment, the lamp body (lamp units 9, 109) is mounted in the roof molding mounting groove 7. However, if the lamp body is a portion of the roof front irradiation surface 6, the roof molding mounting groove 7 is used. You may make it attach to parts other than.
