(1) Visibility of lamp color (2) Visibility of lamp size (3) Visibility of lamp shape (4) Visibility of lamps in various forms

FIG. 1 shows a schematic configuration of an experimental system used for the basic experiment. In this experimental system, the image shown in FIG. 1B projected onto the screen 2 from the projector 1 shown in FIG. 1A is shown to the subject M, and when the subject M inputs an evaluation made based on the image by the switch 3, The personal computer 4 counts the input result. In experiment (1), the emission color, size, shape,
Images of various forms are sequentially inserted into the screen 2 showing the road scenery of FIG. 1B, and the subject M inputs the evaluation of the visibility of the lamp given from those images by the switch 3 as the number of points. I do.

In the experiment (1), a plurality of lamps having different emission colors are set in a stationary state and the visibility is compared. From this experiment, it was found that the visibility of each emission color was good in the order of magenta>green>blue>red>gray>white>cyan> yellow. However, lamps with red emission colors such as magenta and red are legally required.
Since it cannot be provided on the front surface of the motorcycle, it can be seen that the emission color of the lamp used for the visual recognition lamp device is preferably blue or green.

The experiment (2) compares the visibility of the plurality of lamps having different sizes with the lamps at rest. According to the experiment (2), it was found that the visibility of each size was good in the order of LL (maximum)> L (large)> M (medium)> S (small). From the result of the experiment (2), it is understood that the lamp used for the visual recognition lamp device is preferably as large as possible.

In the experiment (3), a plurality of lamps having different shapes of circles, squares, triangles, and crosses are set in a stationary state and the visibility is compared. From this experiment (3), it was found that the visibility of each shape was good in the order of ＞>□>△> ×. According to the result of this experiment (3),
It is understood that a circular lamp is preferably used for the visual recognition lamp device.

The experiment (4) compares the visibility of various forms of the lamp. According to this experiment (4), the visibility of various forms is as follows: moving (fast)> pair (vertical)> blinking (fast)> moving (slow)> blinking (slow)> pair (horizontal)
It was found that the order of ">zoom>still" was good. In addition, the movement (speed) refers to the case where the lamp is moved at a high speed corresponding to the moving body, the pair (vertical) refers to the case where a pair of lamps are arranged vertically, and the blinking (speed) blinks the lamp at a fast cycle. Moving (slow) means moving the lamp at a low speed, blinking (slow) means blinking the lamp at a slow cycle, pair (horizontal) means a pair of lamps arranged on the left and right, Zoom indicates a case where the lamp is gradually increased, and stationary indicates a case where the lamp is stopped. From the result of the experiment (4), it is understood that it is preferable to provide a pair of lamps for the visibility lamp device at the top and bottom or at the left and right, and to blink the lamps.

FIG. 2 is a left side view illustrating a motorcycle equipped with a visual lamp device according to one embodiment of the present invention developed based on the above experimental results, and FIG. 3 is a front view of the motorcycle. . The motorcycle 10 has a front wheel 14 attached to a front fork 13 pivotally supported by a head pipe 12 at the front end of a body frame 11, and a rearwardly mounted swing arm 16 pivotally supported by a swing arm bracket 15 at the lower center of the body frame 11. The wheels 17 are mounted, and the rear wheels 17 are mounted by an engine 18 mounted at the lower center of the body frame 11.
, And is operated by a handle 19 fixed to the upper end of the front fork 13.

The front fork 13 has a bracket 2
The headlamp 21 is attached via the “0”. The viewing lamp device 31 is lit during the day and is viewed from the front, and includes a pair of lamps 32. As shown in FIG. 3, these two lamps 32 are arranged at left and right positions across the headlamp 21, and are respectively fixed to stays 33 welded to the bracket 20 of the headlamp 21. Both lamps 32 are provided at symmetrical positions in order to improve the appearance. Each lamp 3
Reference numeral 2 denotes a general structure in which a front surface of a case accommodating a bulb (light bulb) is covered with a lens, and emits blue or green light that is visible from the front.
The external shape of the lens of the lamp 32 when viewed from the front is circular.

The distance A between the centers of the two lamps 32 is set to 50 mm or more in order to make a difference from the case of a single lamp.
The following is preferred, and the thickness is more preferably 100 to 500 mm. When a pair of lamps 32 are arranged vertically, the distance A between the centers of the lamps is set to 50 mm or more, and is usually preferably 800 mm or less from the limitation of the vehicle body height.
More preferably, Also, here, the outer diameter of the lamp 32 as viewed from the front is 50 to 120 mm.
More preferably, it is set to 〜100 mm. Outer diameter is 50mm
If the distance is less than 120 mm, the visibility decreases. If the distance exceeds 120 mm, the luminance decreases.

Such a configuration is based on the aforementioned (1) to
It is based on the experimental result of (3), and the lamp 32
Not only does the lamp 32 clearly recognize the existence of light, but the lamp 32 is divided into left and right to generate light, so that the position, speed, and the like can be recognized by the viewer. Thereby, the visibility of the lamp 32 is improved.

The lamp 32 repeats blinking. This configuration is based on the experimental result of (4) described above, and allows the viewer to recognize the presence of the lamp 32 more, and
2 improves the visibility. Further, as the lens of the lamp 32, a lens having a scattering lens for scattering light around the lamp is used. In this case, as the scattering lens, for example, a lens in which a cylindrical lens element or a Fresnel lens element having a light distribution function is integrally formed on the front surface or rear surface of the lens can be used. In this way, by using the lamp 32 having the scattering lens, the viewer does not feel dazzling.
The position and speed of No. 2 can be made more recognizable, and the visibility is further improved.

Further, the lamp 32 has a power consumption of 35 W or less per lamp. This is 2,000 candela or less when converted to light source luminous intensity. For example, when the power consumption of one lamp 32 is 27 W or less, the power consumption can be reduced as compared with the case where a head lamp with a power consumption of 55 W is used for visual recognition.

FIGS. 4 and 5 show a motorcycle equipped with the visual recognition lamp device 31 having the above-described configuration, a motorcycle using the head lamp for visual recognition, and a motorcycle in which neither the lamp device 31 nor the head lamp is lit.

The experiment was performed by running the mounted motorcycle, and the evaluation was performed by a subject at the running site.

FIG. 4 shows a comparison of the visibility of each of the motorcycles in which the motorcycle is run independently in the daytime and nighttime, and the superiority and inferiority are determined by the point addition method for the five items shown in FIG. I have. Here, 3 points are given to the first place and 1 point is given to the second place. If the ranking is unknown, no answer is required, and in other cases, 0 point is given. In the figure, "Example" means that the visual lamp device 31 (lens outer diameter 60 mm, center-to-center distance A = 372 mm) is turned on, and "Headlamp" means that the headlamp is used for visual recognition. If lit as
“Non-lighting” indicates the case where neither the visual lamp nor the headlamp is lit, and the numerical value in parentheses indicates the number of points with respect to night driving. A dash in parentheses indicates that the experiment has not been performed because it cannot be evaluated.

As is clear from the experimental results shown in FIG.
The point of the motorcycle running with the visual lamp device 31 having the above configuration turned on in the daytime is much higher than the motorcycle running with the headlights turned on in the daytime and the motorcycle not turning on the lamp, It can be seen that the motorcycle equipped with the visual recognition lamp device 31 is far superior in viewability as compared with the motorcycle using the headlamp for visual recognition.

FIG. 5 shows a comparison of visibility when two motorcycles run side by side in the daytime. Five items in FIG. 4 are used as comparison items. here,
One point was given to the superior and -1 point to the inferior, and no answer was required if the superiority was unknown. Row (1) in FIG. 5 shows other conditions (head lamp,
(Not lit). Similarly, row (2) shows points for other conditions of “headlamp”, and row (3) shows points for other conditions of “non-lighting”.

From the experimental results shown in FIG. 5, it can be seen that the motorcycle in which the visual lamp device 31 having the above configuration is lit during the day is clearly superior in visibility to the motorcycle whose head lamp is lit during the day. I understand.

In the above-described embodiment, the case where the pair of lamps 32, 32 constituting the visual lamp device 31 are arranged on the left and right is shown. However, the present invention is not limited to this. good. The lens of the lamp 32 may have a square or triangular shape when viewed from the front, and may not be a scattering lens.
