  In the rotating lamp unit described in Patent Document 1, since the irradiation angle of the conventional LED is narrow and the amount of irradiation light is small, a plurality of LEDs are arranged on a flat surface, and the irradiation light is reflected by a flat reflecting plate to surround it. Increasing the amount of radiated light to ensure visibility from a distance. Thereafter, the rotating lamp unit described in Patent Document 2 using a single LED has come to be used due to the higher brightness of the LED and the increased irradiation angle. In the rotating lamp unit, the LED is disposed at the focal position of the parabolic reflector to ensure visibility from a distance. In various vehicles equipped with a diffused warning light using a rotating light unit, visibility is required from a road of 150 meters in the road maintenance work vehicle and from 300 meters ahead in an emergency vehicle such as a police vehicle.

  However, since the irradiation light from the wide-angle LED is reflected as substantially parallel light by the parabolic reflector, the viewer who sees the radiated light from a distance can recognize the light only for a short time, and visibility Improvement was more desired.

  The present invention has been made in view of the above problems, and provides a rotating lamp unit, a diffused warning light, and a vehicle using the same, which can further improve the visibility from a distance. Objective.

In order to achieve the above object, a diffused warning light according to claim 1 comprises a main light source and a substantially paraboloidal reflecting member having an annular shape or a partial annular shape focusing on the position of the main light source. When a driving means for rotating the reflecting member around a predetermined rotation axis, a plurality of sub-light sources in the vicinity of the main light source, the plurality of sub-light sources arranged symmetrically around the main light source, In a diffused warning light comprising a plurality of revolving light units in which the reflecting member is provided so as to surround the main light source and the sub light source , each revolving light unit is provided along the left-right direction of the diffused light warning light. The main light source and the sub light source are provided only in a state along the left-right direction of the diffused warning light.

According to the present invention, the light from the main light source is applied to the reflecting member and is emitted outside the rotating lamp unit as parallel light. Therefore, certain visibility from a distance is ensured. Further, since the auxiliary light source is disposed in the vicinity of the focal position of the reflecting member, the emitted light from the auxiliary light source is emitted in an oblique direction while overlapping with the emitted light from the main light source. Therefore, the light of the rotating lamp unit can be visually recognized as a large light as a whole even from a distance, and the visibility can be further improved. Furthermore, it is more preferable that the visible light can be changed depending on the viewing location depending on the relationship between the installation direction of the sub light source with respect to the main light source and the irradiation direction of the rotating lamp unit.

Further, symmetrical light can be visually recognized around the radiated light of the main light source. Further, when the light sources are on the same plane including the irradiation axis, the radiated light shapes can be made equal between the front and rear, the left side, and the right side. By doing in this way, when the irradiation axis of each rotating lamp unit is directed in the front-rear direction, the rotational radiated light from the rotating lamp unit becomes light that spreads in the horizontal direction in the front-rear direction of the diffused warning light. Since the emitted light can be viewed for a long time, the visibility is excellent.

In addition, when the illumination axis of the rotating lamp unit is directed to the left and right sides, the emitted light from the rotating lamp unit becomes light that spreads up and down on the left and right sides of the diffused warning light. Since it is possible to irradiate rotating radiation on a road or the like in the vicinity of the vehicle while being installed in the vehicle or the like while maintaining the performance, it is preferable because the operation of the diffused warning light can be recognized through the road or the like.

Reflected light from the first and second reflecting surfaces is emitted as parallel light in opposite directions. Further, the light from the sub-light source is applied to the first and second reflecting surfaces. The reflected light from the first and second reflecting surfaces is emitted in opposite directions and is emitted in an oblique direction while overlapping with the emitted light from the main light source. Therefore, the same effect as the diffused warning light according to claim 1 can be obtained in both directions.

According to a third aspect of the present invention, in the diffused warning light according to the first or second aspect, the auxiliary light source is disposed on a plane including an irradiation axis of the reflecting member. According to the present invention, the reflected light from the reflecting member of the main light source can be reduced from being blocked by the sub light source, the sub light source installation substrate, and the like, which is preferable for improving the visibility.

It is arranged. According to the present invention, it is possible to effectively irradiate the reflecting member with the irradiation light from the sub-light source. Therefore, since the light from the sub-light source that is not directly irradiated onto the reflecting member can be condensed and reflected by the reflecting member, the amount of light emitted to the outside is increased. Therefore, visibility can be further improved.

According to a fifth aspect of the present invention, in the diffused warning light according to the fourth aspect of the present invention, the light collecting member is formed of a translucent member provided with a convex portion. According to the present invention, it is preferable because the light from the sub-light source can be condensed in a limited space.

Therefore, when an emergency car enters an intersection or a T-junction, the driver of the vehicle who intends to enter the intersection or the T-junction similarly uses the light illuminated on the road even if the emergency car is not visible. It can be visually recognized. The rotating lamp unit 2a disposed at the left end can also illuminate the left road surface on which the emergency vehicle travels when the irradiation axis of the rotating lamp unit 2a is directed in the left-right direction LR.

  Further, when the irradiation axes of the rotating lamp units 2b and 2c provided at the center right side and the left side are directed in the front-rear direction FB, the road surface before and after the emergency vehicle travels can be illuminated. By combining the rotating lamp units 2a, 2b, 2c, and 2d in this way, the road surface of the entire circumference of the front, rear, left, and right can be illuminated, and thus visibility can be further improved.

The auxiliary light sources 8 and 9 are arranged symmetrically along the left-right direction LR with the main light source 7 as the center, and the pair of new auxiliary light sources are arranged symmetrically along the front-rear direction FB with the main light source 7 as the center. The By arranging each sub-light source at the above-mentioned four locations, light spreading in the vertical and horizontal directions FBLR can be emitted, so that the visibility can be further improved.

  If each light source has a long distance between the light sources, the light emitted from the rotating lamp unit can emit light that spreads in the vertical and horizontal directions. . In addition, when the distance between each light source is short, the light emitted from each sub-light source can emit light that further overlaps the parallel light emitted from the main light source. Can be improved. In addition, in order to condense the light of a pair of new sub light source, you may provide a new 3rd and 4th convex part in the translucent member 32. FIG. In this case, the third and fourth convex portions are respectively installed above the new sub-light source, and have the same shape as the first and second convex portions 11 and 12.
