The bolts 19 are inserted into the through holes and fastened to the rectangular nuts arranged in the first upper grooves 73, whereby the substrate 12 is held on the base 7 via the fixing member 9.

  The bracket 8 is slidably engaged with the base 7 so that the light emitting unit 6, the substrate 12, and the cover 5 can be fixed to the base 7. Each bracket can be fixed with a single bracket, and it is not necessary to design a dedicated part for fixing, so the versatility is high. Parts can be shared and the number of parts to be designed can be reduced.

(Light emitting unit 6)
7 to 9 are diagrams showing the light emitting unit 6. 7A is a plan view, FIG. 8B is a side view, FIG. 8 is a sectional view taken along line VIII-VIII in FIG. 7B, and FIG. 9 is an exploded view.

  The light emitting unit 6 emits light and gives a warning to the surroundings with light. The light emitting units 6 are arranged over the entire circumference of the warning light main body 2 so that the optical axis is directed outward, and each light emitting unit 6 is controlled to sequentially flash in the circumferential direction. Thereby, it can be visually recognized as if the light is rotating around the warning light main body 2.

  Conventionally, a rotating reflector for diffusing light around a light emitter is arranged, and light is diffused around by rotating the rotating reflector. In such a configuration, the height is required to some extent, and the warning light is attached to the roof of the vehicle, so that the vehicle height becomes high, and there is a problem of being caught in a height restriction such as a tunnel or a parking lot, and a problem of increasing weight. there were. In the present embodiment, the height can be significantly suppressed by controlling the lighting using the LED. Space-saving and light weight could be achieved. It is possible to control lighting of the light emitting units 6 individually, and it is easy to light up with abundant variations.

  The light emitting unit 6 includes a base 61, a light guide 64, and a cover lens 65.

  The base 61 includes a rectangular flat plate portion 61a extending in one direction and an inflating portion 61b that swells loosely in the thickness direction of the flat plate portion 61a. A flexible substrate is arranged according to the curved surface of the inflating part 61b, and a plurality of LED light sources 63 are arranged at equal intervals on the flexible substrate. The light source 64 covers the LED light source 63, and the cover lens 65 covers the whole.

  The light guide body 64 is curved in accordance with the curved surface of the expanding portion 61 b, and numerous indentations are formed on the curved surface on the optical axis of the LED light source 63. Since the light emitted from the LED light source 63 has a strong linearity, if the light guide has a rectangular parallelepiped block shape, the light is emitted only forward and has poor diffusivity, and is only visible to those on the straight line in front. The By forming the inflating portion 61b, the LED light source 63 is disposed on the inflating portion 61b, and the light guide body 64 is also curved, the light diffusion angle is increased and the visibility is improved.

  The cover lens 65 is a translucent material colored in red, for example. A white light emitting diode is used for the LED light source 63, and light emitted from the LED light source 63 passes through the red cover lens 65 and is emitted as red light. In the present embodiment, a white light emitting diode is used for the LED light source 63, but a light emitting diode having a cover lens color (for example, red in the present embodiment) may be used. The light emitting unit 6 can easily cope with, for example, blue light used for warning light of foreign police cars by changing the light emission color of the LED light source 63 and the color of the cover lens 65. Further, by using a different cover lens 65 for each light emitting unit 6, it is possible to cope with multicolor light.

  Conventional warning lights use an outer lens consisting of a single part even if it is long. In order to cope with multicolor light, the color of the outer lens is divided, and the boundary between different colors is subjected to a light shielding process in order to avoid color mixing. Therefore, the structure is complicated and the manufacturing cost is high. According to the configuration of the present embodiment, it is not necessary to change the internal structure or perform a light shielding process, and it is possible to easily create a light emission pattern that is multicolored and rich in variations.

  The wiring extending from the light emitting unit 6 (flexible substrate) is connected to the substrate 12. The wiring of each light emitting unit 6 is collected on the substrate 12 and lighting is controlled. Each light emitting unit 6 and the substrate 12 are waterproofed by a sheath material (not shown). A waterproof connector is used as a connector used for connecting these parts, and the connection portion is also waterproofed.

  The conventional warning light was waterproofed with a long packing covering the whole, but the packing of the warning light, which is a long product, was very large and the waterproofness was not sufficient. In this embodiment, since it is the structure waterproofed for every component, the packing which covers the whole is unnecessary. The waterproofness is improved and the occurrence of problems due to water droplets can be prevented. In addition, parts can be easily replaced in the event of a failure, and maintainability is also high.
