  Referring to FIG. 3, an LED mounting board 42 that is a main part of the light emitting unit 4 is housed inside the left warning notification unit 23 </ b> L and the right warning notification unit 23 </ b> R. The light emitting unit 4L is accommodated in the left warning notifying unit 23L located on the left direction XL side, and the light emitting unit 4R is accommodated in the right warning notifying unit 23R located on the right direction XR side. is there. In the light emitting unit 4L, a plurality of LEDs 41 are mounted on the LED mounting substrate 42 in a state of being connected in the vertical direction Z.

  The thickness 23LW in the left-right direction X of the left warning notification unit 23L and the thickness 23RW in the left-right direction X of the right warning notification unit 23R are large enough to accommodate the light emitting unit 4L. It is necessary that the warning display be visible from 300 meters ahead when the vehicle is mounted on an emergency vehicle and 150 meters ahead of the vehicle when the vehicle is mounted on a road maintenance work vehicle. This is based on Japanese laws and regulations for warning lights used in emergency vehicles and road maintenance work vehicles, and is set to satisfy the requirements. Further, by increasing the thicknesses 23LW and 23RW, the visibility from the front direction YF can be improved, but it is also assumed that it cannot be accommodated in the number plate mounting space of the front portion of the automobile to be installed. Therefore, the warning notification effect is improved by providing the left warning notification portion 23L and the right warning notification portion 23R so that the size of the warning light 2 is substantially equal to the installation space of the license plate in the front portion of the automobile. be able to.

  The thickness 24UH in the up-down direction Z of the upper connecting portion 24U and the thickness 24DH in the up-down direction Z of the lower connecting portion 24D are determined when the number plate 3 is attached to the license plate mounting surface 21 and the emergency vehicle 1 and is used. It is sufficient that the warning notification unit 23 can be held so that there is no structural change such as twisting, and the connecting unit 24 can be omitted if the thickness can be reduced or the structural change can be prevented by other methods.

  4, 5, and 6, the light emitting unit 4 includes an LED mounting substrate 42 on which an LED (group) 41 is mounted. The LED (group) 41 is a surface-mounted LED, and one that emits red light when the warning light 2 is used in an emergency automobile application is used. When the warning notification unit 23 is formed of, for example, a red transparent resin without being formed of a colorless transparent resin, the LED 41 that emits white light may be used without using a red light emitting LED. Further, the irradiation optical axis of the LED (group) 41 is directed in the left-right direction X, and the directly radiated light is radiated from the outside of the warning light 2 main body, and the light emission state of the LED (group) 41 can be visually recognized from the outside. . In this embodiment, a surface-mounted LED is used as the LED (group) 41, but this is not the only case.

The rear panel 5 and the inner surface 28R lock the light emitting unit 4 in the front-rear direction Y. The inner surface 28R is an inner surface that is located on the right side XR side of the inner surface 28 of the main body of the warning light 2 in the space surrounded by the warning notification unit 23L and the rear panel 5. Of the inner surface 28, the inner surface located on the front YF side is the inner surface 28F, and the inner surface located on the left XL side is the inner surface 28L. On the inner surface 28F, there is a mounting substrate locking portion 6 (radiated light diffusion portion 6) protruding so as to sandwich the LED mounting substrate 42. For fixing the light emitting unit 4 in the vertical direction Z, the upper end portion 44U and the lower step portion 44D of the LED mounting substrate 42 are held by the upper end holding portion 26U and the lower end holding portion 26D of the upper and lower end holding portion 26 of the warning light 2 body. . The upper end holding part 26U and the lower end holding part are symmetrical.

More specifically, it is carried out by sandwiching the short direction locking portions 44 located at the upper and lower ends of the LED mounting substrate 4. The short direction locking portion 44 has two upper and lower portions, a short direction locking portion 44U on the upper ZU side and a short direction locking portion 44D on the lower ZD side. (Group) 41 is not mounted. When the LED mounting board 4 is inserted into the warning light 2 main body, the short direction locking portion 44U is inserted and locked into the upper end holding portion 26U, and the short direction locking portion 44D is inserted along the lower end holding portion 26D. Stopped. At the same time, the longitudinal direction locking portions 43 and 43F located on the front YF side of the LED mounting substrate 41 are inserted and locked into the mounting substrate locking portion 6 (radiated light diffusion portion 6) of the warning lamp 2 body. Thereafter, the longitudinal locking portions 43 and 43R located on the rear YR side of the LED mounting substrate 41 and the longitudinal side surfaces of the LED mounting substrate 41 are sandwiched between the rear panel 5 and the rear longitudinal locking portion 52 of the rear panel 5. To do.

  The mounting substrate locking portion 6 (the emitted light diffusion portion 6) is a portion that protrudes inward from the inner surface 28F in a substantially triangular shape. The mounting board locking portion 6 is located outside the half-value width F of the emission intensity of the LED (group) 41. Further, the mounting board locking portion 6 has a diffusing material mixed therein, and by receiving the light emitted from the LED (group) 41, it can be visually recognized from the outside as if that portion is emitting light. In other words, the mounting board locking portion 6 has a function of diffusing emitted light from the LED (group) 41, and makes it appear as if the entire portion is emitting light, and in combination with the warning light 2 body, the front notification portion 23R2 , 23L2.

  The reason why the mounting board locking portion 6 is substantially triangular is to allow the incident light from the LED (group) 41 to be visually recognized from the outside of the warning lamp 2 efficiently. When the warning lamp 2 is viewed from a direction within the half-value width F of the emission intensity of the LED (group) 41, the LED (group) 41 can be directly visually recognized through the transparent warning lamp 2 body. it can. When the warning lamp 2 is viewed from a direction outside the half-value width F of the emission intensity of the LED (group) 41, the light emission state of the LED (group) 41 cannot be directly visually recognized, but the mounting board locking portion 6 (radiated light) It can be visually recognized as a large light emitting surface as if the diffuser 6) is emitting light.

The side notification unit 23L1 is a portion on which radiated light within the half-value width F of the emission intensity of the LED (group) 41 is incident. Of the inner surface 28, portions corresponding to the side notification portion 23L1 are the inner surface 28L and a part of the inner surface 28F. If the protrusion height of the side notification portion 23L1 toward the front Y is increased, the side notification portion 23L1 is easily visible from the side. Also, a convex height 23H, which is the difference between the license plate mounting surface 21 and the front surface of the left warning notification unit 23L1, is designed so that the side notification unit 23L1 does not block the license plate 3 when viewed from an oblique direction. To do. The front notification portion 23L2 is a portion into which radiated light outside the half-value width F of the emission intensity of the LED (group) 41 is incident, and is a portion where the mounting substrate locking portion 6 is formed in the inner surface 28F.

  The back plate 5 has a fitting portion 51 that engages with a fitting portion 27 at the end of the inner surface 28 on the rear direction YR side (back side) at the outer edge of the side surface. Further, when the light emitting unit 4 is housed, the back plate 5 has a longitudinal locking portion 52 that locks the longitudinal locking portion 43 </ b> R of the LED mounting substrate 42. The fitting part 51 forms the outer edge of the warning light 2 rearward direction YR side (back surface). The longitudinal locking portion 52 has a position and size where the light within the half-value width F of the LED (group) 41 is not irradiated. A surface 53 in a plane surrounded by the fitting part 51 and the longitudinal locking part 52 is a surface to which light within the full width at half maximum F of the LED (group) 41 is irradiated. A light reflection process such as a mirror surface process is applied so as to radiate to the notification unit 23L1.

Referring to FIG. 7, a warning light 2 is installed at the forefront portion of the front portion 11 of the emergency vehicle 1. The irradiation light DL1 from the left warning notification unit 23L of the warning lamp 2 in the left direction XL is radiated with relatively strong light within the half-value width F of the emission intensity of the internal LED (group) 41. In the angle range FA where the irradiation light DL1 is visually recognized, the light emission state of the LED (s) 41 inside the warning lamp 2 can be directly visually confirmed. The irradiation light DL2 in the right direction XR from the right warning notification unit 23R of the warning lamp 2 is radiated with relatively strong light within the half-value width F of the internal LED (group) 41. In the angle range FB where the irradiation light DL2 is visually recognized, the light emission state of the LED (group) 41 inside the warning light 2 can be directly visually confirmed. The irradiation light DL1 and the irradiation light DL2 emit warning light around a horizontal side that is a direction away from each other.

  The irradiation light DL3 and the irradiation light DL4 from the warning lamp 2 to the front YF are relatively weak light outside the full width at half maximum F of the internal LED (group) 41, and the mounting board locking portion 6 (radiated light diffusion portion 6). What is irradiated is visually recognized. At this time, the internal LED (group) 41 cannot be directly recognized, and the mounting board locking portion 6 and the front notification portions 23L2 and 23R2 that have received the radiation of the LED (group) 41 are visually recognized as surface emitting portions.

  With this configuration, when viewed from diagonally forward YF and XL, another diagonally forward YF and XR, irradiation DL1, DL3 and irradiation DL2, DL4 can be continuously viewed, so the front portion 11 of the emergency vehicle 1 Warning light can be visually recognized around the entire area.

  As an embodiment of the present invention, the mounting substrate locking portion 6 (radiated light diffusion portion 6) has been described as having a shape protruding in a substantially triangular shape, but is not limited thereto. A substantially trapezoidal shape or a substantially curved surface shape may be minimized. Furthermore, although the mounting board | substrate latching | locking part 6 (radiated light diffusion part 6) was demonstrated as what was integrated and protruded from the inner surface 28F, it is not limited to this. The mounting board locking part 6 (radiated light diffusion part 6) may be provided as a separate member from the inner surface 28F, and it is only necessary that the mounting board 42 can be locked using this.
