Description

  The present invention relates to a warning light.

Some warning lights, for example, are installed in emergency vehicles and emit warning signals such as rotating flashlights. Specifically, such a warning light has a revolving light attached to a base and a reflecting plate that reflects light from the revolving light (see, for example, Patent Documents 1 and 2). .
In patent document 1, it is proposed to form a slit in a reflecting plate in a warning light installed on the roof of a vehicle. Specifically, the warning light has first and second reflecting plates having different distances from the rotating lamp. A slit is formed in the first reflector on the side close to the rotating lamp. The rotating lamp light that has passed through the slit is applied to the second reflector on the side far from the rotating lamp. The rotating lamp light is reflected by the first and second reflectors.

  In Patent Document 2, in a warning light installed on a side surface of a vehicle, a first reflecting plate that reflects light from a first rotating lamp and a second reflection that reflects light from a second rotating lamp. It has been proposed to displace the plates in the vertical direction.

  By the way, the warning light installed on the roof of an emergency vehicle or the like includes a thin type having a V-shaped base in order to suppress air resistance when the vehicle travels at a high speed. This type of base has a central portion and a pair of left and right wings extending diagonally rearward from the central portion to the left and right. A rotating lamp and a reflecting plate are disposed on the wing portion. In addition, a speaker is disposed at the center. In a thin warning light in which the height of the warning light is regulated, a rotating light having a high height cannot be arranged at the center of the base on which the speaker is arranged. As a result, the visibility of the central part of the warning light when viewed from behind tends to be low.

  Moreover, in order to improve the visibility of a thin warning light, it is possible to apply the technique using the reflecting plate of patent document 1, 2. FIG. However, in Patent Document 1, since the light irradiated in one direction from one rotating lamp is divided and reflected by the first and second reflecting plates, the light on each reflecting plate becomes weak, and the visibility is sufficient. It cannot be improved. Moreover, patent document 2 cannot be applied to a thin warning light.

There is also a demand to reduce the manufacturing cost of warning lights.
Then, the objective of this invention is providing the cheap warning light which can improve the visibility of the center part when it sees from back.

  In order to achieve the above object, a warning light according to the present invention includes a V-shaped base including a central portion and a pair of left and right wings extending obliquely rearward from the central portion and lower than the central portion.

It is a warning light characterized by being.

  According to the present invention, visibility from a wide range of surroundings can be enhanced by the rotating lamp unit. Further, the front and rear visibility can be further enhanced by the fixed lamp unit and the first to fourth reflectors. Further, the fourth reflecting plate is disposed in the vicinity of the central portion of the base, and can reflect the rotating lamp light and the fixed lamp light in the backward direction. Accordingly, it is possible to improve the visibility of the central portion of the warning light from the rear. Further, since the rotating lamp light and the fixed lamp light are reflected by the common fourth reflecting plate having a simple structure, the manufacturing cost can be reduced.

In the present invention, the fixed lamp unit may include a reflecting mirror that reflects the light emitted from the plurality of LEDs into parallel light. In this case, even if the directivity in the irradiation direction of the LED is high, the fixed lamp light can be visually recognized in a planar shape when viewed from the surroundings. Therefore, visibility can be further improved.
Further, in the present invention, the fixed lamp unit blinking lighting timing and the rotating lamp unit rotation lamp light passing through the slit so that the reflected light reflected by the fourth reflecting plate appears to blink. There is a case in which a control unit that synchronizes the lighting timing and the passage timing with each other is controlled. In this case, when viewed from the rear, the reflected light from the fourth reflecting plate appears to blink, so that the visibility can be further enhanced.

The rotating lamp unit 7 rotates and emits light from the light source 31 over its entire circumference.

  For the light source 31, for example, at least one light emitting diode (also referred to as LED) is used. The reflecting mirror 32 reflects the light from the light source 31 as parallel light in predetermined irradiation directions A3 and A4. Irradiation directions A3 and A4 are directions orthogonal to the rotation center axis 35, and are two directions opposite to each other. The base 34 fixes the light source 31 and supports the reflecting mirror 32 in a rotatable manner. The rotation center axis 35 of the reflecting mirror 32 extends along the vertical direction. The drive mechanism 33 includes an electric motor (not shown) as a drive source, and can rotate the reflecting mirror 32 around the rotation center axis 35 under the control of the control unit 19. As the reflecting mirror 32 rotates, the irradiation directions A3 and A4 of the reflected light by the reflecting mirror 32 gradually change.

FIG. 4 is a schematic diagram of the warning light 1 of FIG. 1 in a plan view, and shows an irradiation state of rotating lamp light. FIG. 5 is a schematic view of the warning light 1 of FIG. 1 in a plan view and shows an irradiation state of the first fixed lamp light. FIG. 6 is a schematic diagram of the warning light 1 of FIG. 1 in a plan view, and shows an irradiation state of the second fixed lamp light. FIG. 7 is a schematic view of the warning light 1 of FIG. 1 in a plan view, and shows a light irradiation state from the central portion of the warning light 1 to the rear B1.

With reference to FIGS. 2 and 5, the first reflector 11 and the second reflector 12 are disposed between the rotating lamp unit 7 and the first fixed lamp unit 8 in each wing 23. The first reflecting plate 11 reflects the first fixed lamp lights L21 and L22 toward the front F1. The second reflecting plate 12 reflects the first fixed lamp light L24 toward the rear B1.
The third reflecting plate 13 is disposed behind the second reflecting plate 12 in each wing 23. Here, “behind the second reflecting plate 12” includes a position immediately behind and a position shifted in the left-right direction from the position immediately behind. Part of the first fixed lamp lights L25 and L26 reaches the third reflecting plate 13 while avoiding the first reflecting plate 11 and the second reflecting plate 12.

With reference to FIGS. 3 and 5, the third reflecting plate 13 includes a plurality of slits 40. The third reflector 13 has a rotating lamp light reflecting surface 41 for reflecting rotating lamp light and a fixed lamp light reflecting surface 42 for reflecting the first fixed lamp light of the first fixed lamp unit 8 on the front and back sides.
The rotating lamp light reflecting surface 41 is formed on one surface of the third reflecting plate 13, and the slit 40 is defined on this surface. The fixed lamp light reflecting surface 42 is formed on the other surface of the third reflecting plate 13, and the slit 40 is defined on this surface.

Referring to FIG. 4, the rotating lamp light reflecting surface 41 of the third reflecting plate 13 reflects the rotating lamp light L31 obliquely rearward. The slit 40 of the third reflecting plate 13 allows the rotating lamp light L32 to pass through. The rotating lamp light L32 that has passed through the slit 40 is irradiated toward the fourth reflector 14.
Referring to FIG. 5, the fixed lamp light reflecting surface 42 of the third reflecting plate 13 reflects the first fixed lamp light L25 toward the fourth reflecting plate 14. The slit 40 of the third reflecting plate 13 allows the first fixed lamp light L26 to pass through. The fixed lamp light L26 passing through the slit 40 is irradiated obliquely backward.

  With reference to FIG. 7, at least a part (a part in the present embodiment) of the fourth reflecting plate 14 is arranged behind the first fixed lamp unit 8 in each wing part 23. The fourth reflector 14 reflects the rotating lamp light L32 and the first fixed lamp light L25 to the rear B1. Specifically, the first fixed lamp light L25 is reflected by the fourth reflector 14 through the fixed lamp light reflecting surface 42 of the third reflector 13, and the rotating lamp light L32 is the third lamp light L32. The reflected light L3 reflected by the fourth reflecting plate 14 through the slit 40 of the reflecting plate 13 is superimposed and irradiated to the rear B1.

The irradiation direction of the reflected light L3 at this time changes in the angle range D13 as the reflecting mirror 32 of the rotating lamp unit 7 rotates. The fact that the reflected light L2 and the reflected light L3 are superposed is sufficient if the reflected light L2 and the reflected light L3 are parallel to each other in plan view as the reflecting mirror 32 of the rotating lamp unit 7 rotates.
With reference to FIGS. 2 and 4, the fifth reflector 15 is adjacent to the first reflector 11 on the upper surface of the wing 23 of the base 5 and is more forward than the first reflector 11. Is arranged. The fifth reflector 15 reflects the rotating lamp light L33 obliquely forward. The irradiation direction at this time changes in the angle range D11 as the reflecting mirror 32 of the rotating lamp unit 7 rotates.

Further, the third reflecting plate 13 and the fifth reflecting plate 15 block the rotating lamp light. Thereby, the irradiation directions A3 and A4 of the reflecting mirror 32 of the rotating lamp unit 7 change in the angle range D14 as the reflecting mirror 32 of the rotating lamp unit 7 rotates.
According to the present embodiment, as shown in FIG. 4, visibility from a wide surrounding area can be enhanced by the rotating lamp unit 7. Further, as shown in FIG. 5, the first fixed lamp unit 8 and the first to fourth reflectors 11, 12, 13, 14 further enhance the visibility when viewed from the front and rear. Can do. Further, referring to FIG. 7, the fourth reflecting plate 14 is disposed in the vicinity of the central portion 22 of the base 5, and the rotating lamp light L <b> 32 and the first fixed lamp light L <b> 25 are overlapped and reflected to the rear B <b> 1. it can. Therefore, the visibility of the central part of the warning light 1 from the rear can be improved. Further, since the rotating lamp light L32 and the first fixed lamp light L25 are reflected by the common fourth reflecting plate 14 having a simple structure, the manufacturing cost can be reduced.

  The width of the slit 40 of the third reflector 13 is much smaller than the normal distance when the warning light 1 is viewed from the surroundings, and there are a plurality of slits 40. In addition, the irradiation direction of the rotating lamp light L32 and the first fixed lamp light L25 is usually not a single direction but slightly spread. As a result, when the central portion of the warning light 1 is viewed from behind, the reflected light L2 and the reflected light L3 appear to overlap each other. Therefore, it can be said that the reflected light L2 and the reflected light L3 substantially overlap.

  Referring to FIG. 2, the first fixed lamp unit 8 of the present embodiment includes a reflecting mirror 37 that reflects light emitted from the plurality of LEDs 36 to make parallel light. In this case, even when the directivity of the irradiation direction of the LED 36 is high, the first fixed lamp light can be visually recognized in a planar shape when viewed from the surroundings. Therefore, visibility can be further improved. Further, the LED 36 consumes less power and has a long life. The same effect can also be obtained in the second fixed lamp unit 9.

With reference to FIG. 4, the rotating lamp unit 7 and the fifth reflecting plate 15 can further enhance the visibility when viewed from the left and right obliquely forward.
With reference to FIGS. 2 and 6, the second fixed lamp unit 9 is configured in the same manner as the first fixed lamp unit 8. The second fixed lamp unit 9 will be described focusing on the differences from the first fixed lamp unit 8. About the structure of the 2nd fixed lamp unit 9, the same code | symbol as the corresponding structure of the 1st fixed lamp unit 8 is attached | subjected, and description is abbreviate | omitted.

The reflecting mirror 37 of the second fixed lamp unit 9 reflects the light emitted from the plurality of LEDs 36 as the light source of the second fixed lamp unit 9 to make it parallel light. This parallel light is irradiated obliquely forward.
The sixth reflecting plate 16 and the seventh reflecting plate 17 are arranged on the irradiation direction A2 side with respect to the second fixed lamp unit 9 in the front half of the upper surface of the central portion 22 of the base 5. The sixth reflector 16 reflects the second fixed lamp light L51 toward the front F1. The seventh reflecting plate 17 reflects the second fixed lamp light L52 toward the front F1.

The sixth reflecting plate 16 and the seventh reflecting plate 17 are spaced apart from each other in the lateral direction. The second fixed lamp light L53 passes between the sixth and seventh reflectors 16 and 17. The second fixed lamp light L53 passing through here is irradiated obliquely forward.
The second fixed lamp unit 9, the sixth reflecting plate 16, and the seventh reflecting plate 17 can further improve the visibility when viewed from the front and diagonally forward from the left and right.

  With reference to FIGS. 1 and 3, each of the first, third, fifth, sixth and seventh reflectors 11, 13, 15, 16 and 17 has a plurality of slits 40. Although not shown, it is conceivable to form slits 40 in the second and fourth reflectors 12 and 14. When at least one of the first to seventh reflecting plates 11, 12, 13, 14, 15, 16, 17 includes the plurality of slits 40, the visibility of the warning light 1 can be further enhanced. it can.

The slit 40 penetrates both front and back surfaces of the first to seventh reflecting plates 11 to 17 in which the slit 40 is formed. Each slit 40 extends in the vertical direction and is partitioned by a reflecting surface. The plurality of slits 40 are arranged in the horizontal direction.
With reference to FIG. 5, the first fixed lamp light L <b> 23 passes through the slit 40 of the first reflecting plate 11 and is irradiated obliquely rearward.

Referring to FIG. 4, rotating lamp light L34 passes through slit 40 of fifth reflector 15 and is irradiated obliquely forward. The irradiation direction at this time changes in the angle range D12 as the reflecting mirror 32 of the rotating lamp unit 7 rotates.
Referring to FIG. 6, the second fixed lamp light L54 passes through the slit 40 of the sixth reflector 16 and is irradiated obliquely forward. The second fixed lamp light L55 passes through the slit 40 of the seventh reflecting plate 17 and is irradiated obliquely forward.

  FIG. 8 is a timing chart of the control unit 19, and the vertical axis corresponds to the rotation angle D1 of the reflecting mirror 32 of the rotating lamp unit 7 and the lighting (ON) and extinguishing (OFF) of the first fixed lamp unit 8. The command signal is shown, and the elapsed time t is shown on the horizontal axis. Referring to FIGS. 7 and 8, the control unit 19 makes the first fixed lamp unit so that the reflected lights L <b> 2 and L <b> 3 reflected by the fourth reflector 14 appear to blink when viewed from the rear. 8 at least one of the lighting timings t1 to t2 and t3 to t4 of the blinking and the passing timings t5 to t6 and t7 to t8 through which the rotating lamp light L32 of the rotating lamp unit 7 passes through the slit 40 of the third reflecting plate 13 is controlled. Thus, the lighting timing and the passing timing are synchronized with each other.

Thereby, when it sees from back, since the reflected lights L2 and L3 from the 4th reflecting plate 14 seem to blink, visibility can be improved further. Here, at least a part of the lighting timings t1 to t2 and t3 to t4 and at least a part of the passage timings t5 to t6 and t7 to t8 need only coincide with each other.
Specifically, the control unit 19 can blink the first fixed lamp unit 8 at a desired timing. The lighting timing, which is the lighting timing, is controlled as follows. Center timings t11 and t12 of passing timings t5 to t6 and t7 to t8 through which the rotating lamp light of the rotating lamp unit 7 passes through the slit 40 of the third reflector 13 and centers t13 and t14 of lighting timings t1 to t2 and t3 to t4. Are synchronized with each other. Thereby, the reflected lights L2 and L3 reflected by the fourth reflecting plate 14 appear to blink.

  In addition, the control unit 19 can detect the rotation angle D1 of the reflecting mirror 32 of the rotating lamp unit 7. For example, the rotation angle of the output shaft of the electric motor of the drive mechanism 33 of the rotating lamp unit 7 is detected. For detection, an angle detection sensor (not shown) for detecting the rotation angle of the output shaft of the electric motor is used. An angle detection sensor is connected to the control unit 19. Alternatively, a stepping motor as an electric motor capable of controlling the rotation angle of the output shaft to a desired angle may be used, and this stepping motor may be controlled by the control unit 19.

  It is assumed that the rotation angle D1 of the reflecting mirror 32 is 0 degree when the irradiation direction A3 of the reflecting mirror 32 of the rotating lamp unit 7 faces directly in front. When the rotation angle D1 of the reflecting mirror 32 of the rotating lamp unit 7 becomes a value within a predetermined angle range (for example, 80 to 100 degrees and 260 to 280 degrees) (corresponding to the above-described passage timings t5 to t6 and t7 to t8). ), The rotating light L32 of the rotating lamp unit 7 reaches the fourth reflecting plate 14 through the slit 40 of the third reflecting plate 13. And the reflected light L3 is visually recognized from back.

  Further, when the rotation angle D1 of the reflecting mirror 32 of the rotating lamp unit 7 becomes a predetermined angle (for example, 90 degrees and 270 degrees) (corresponding to the above-described passage timing centers t11 and t12), the rotating lamp unit. The irradiation direction A3 of the seventh reflecting mirror 32 and the reflection direction in which the first fixed lamp light L25 is reflected by the fixed lamp light reflecting surface 42 of the third reflecting plate 13 are parallel to each other. As a result, when viewed from the rear, both the rotating lamp light L32 and the first fixed lamp light L25 are visually recognized through the fourth reflecting plate 14.

Further, the lighting cycle of the first fixed lamp unit 8 and the rotation light emission cycle of the rotating lamp unit 7 (corresponding to half the rotation cycle of the reflecting mirror 32 in this embodiment) coincide with each other. .
Specifically, when the rotation angle D1 of the reflecting mirror 32 of the rotating lamp unit 7 is in the range of 90 ° ± 45 ° and in the range of 270 ° ± 45 °, the controller 19 1 fixed lamp unit 8 is turned on. When the rotation angle D1 of the reflecting mirror 32 is outside the angle range described above, the control unit 19 turns off the first fixed lamp unit 8.

In addition, when the above-mentioned lighting timing and the above-mentioned passage timing shift | deviate mutually, for example, it may seem that it is always lighting.
Moreover, the following modifications can be considered about this embodiment. In the following description, the points different from the above-described embodiment will be mainly described. In addition, about another structure, it is the same as that of the above-mentioned embodiment.

For example, it is conceivable to fix the fourth reflecting plate 14 to the central portion 22 of the base 5. Further, the slit 40 of any one of the first, second, and fourth to seventh reflectors 11, 12, 14, 15, 16, and 17 can be eliminated, It is also conceivable to eliminate at least one of the seven reflectors 15, 16, and 17.
Further, at least one of the first and second fixed lamp units 8 and 9 is always lit, and at least one of the first and second fixed lamp units 8 and 9 is rotated by the reflecting mirror 32 of the rotating lamp unit 7. It is also conceivable to blink at an arbitrary timing unrelated to the angle. In these cases, when the central portion of the warning light 1 is viewed from the rear, the intensity of light changes and the visibility is improved. It is also conceivable to eliminate the second fixed lamp unit 9. In addition, various design changes can be made within the scope of matters described in the claims.
