[0002]
[Prior art]
2. Description of the Related Art Conventionally, a rotary warning light configured to effectively use the full width of a vehicle on the roof of a vehicle has been widely used. As shown in FIGS. 8 and 9, this type of rotary warning lamp 51 has a structure in which a pair of rotary lights 53, 53 are arranged on both left and right sides of a base 52 formed in a substantially rectangular shape. Each rotating lamp 53 joins a pair of primary reflecting mirrors 54 formed in a substantially bowl shape back to back, and a conductive roller or gear around a light source (not shown) arranged and fixed at the center of the joint. It is configured to rotate using the drive mechanism 55 (in the direction of arrow A). Further, a secondary reflecting mirror 56 is installed at an intermediate portion between the rotating lamps 53 and 53. As shown in the illustrated example, the secondary reflecting mirror 56 has reflecting surfaces in four directions, and these reflecting surfaces are positioned on the four sides of the rhombus when viewed from the plane, and between the reflecting surfaces. The joint portion, that is, the apex portion in the rhombus shape, is configured so as to be positioned in the front-rear direction and the left-right direction on the base 52.
[0003]
In general, the rotating lamps 53 and 53 and the secondary reflecting mirror 56 arranged in this way are generally covered with a light-transmitting glove for waterproofing, dustproofing, windproofing, etc., and the inside is often a sealed structure. For example, a plurality of translucent glove pieces 57, 57... Formed of synthetic resin materials having different colors are integrally connected to each other, and the lower side notch of each translucent glove piece 57, 57. Covering the rotating lamps 53 and 53 and the secondary reflecting mirror 56 placed on the base 52 by fitting and fixing them in a fixing groove (not shown) formed on the upper edge of the base 52, and In this structure, both side openings are sealed with translucent globe covers 58 and 58.
[0004]
[Problems to be solved by the invention]
However, in the conventional rotary warning lamp 51, as shown in FIG. 9, each rotary lamp 53, 53, that is, the primary reflecting mirror 54 is rotated by the drive mechanism 55 to irradiate the irradiation light of the light source in a substantially horizontal circumferential direction. be able to. Further, the irradiation light can be reflected by the secondary reflecting mirror 56 and the reflected light can be projected in the front-rear direction (arrow F and arrow R), and the irradiation light and the reflected light all irradiate the same amount of light in the front-rear direction. It was something to do. For this reason, when the rotary warning lamp 51 is turned on, not only the amount of light behind the vehicle is wasted, but there is a problem that another structure is required for anti-glare to the rear. .
[0005]
Further, the conventional rotary warning lamp 51 has a complicated structure such as a drive mechanism 55 and a secondary reflecting mirror 56 for rotating the rotary lamps 53, 53, and the assembly work thereof becomes complicated. Once the rotary lamps 53 and 53 and the secondary reflecting mirror 56 are assembled on the base 52, there is a problem that the arrangement cannot be easily changed.
[0006]
The present invention was devised in view of the above problems, and by using a reflector type unit using a light source that blinks in place of a conventional rotating lamp and an inner lens type unit, an inner lens type unit is obtained. Light is emitted from the light source by increasing the amount of light in a specific direction, particularly in the front of the vehicle, by irradiating in the substantially horizontal circumferential direction from the outer surface of the inner lens. The purpose is to improve the warning function as a flashing warning light.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the flashing warning light according to the present invention is configured to house a plurality of warning light units in a light-transmitting globe and to emit a warning light by flashing the light source of the warning light unit as desired. The gist of the flashing warning light is that the plurality of warning light units are constituted by a combination of at least one reflecting mirror type unit and an inner lens type unit.
[0008]
The inner lens type unit covers a cylindrical inner lens formed by forming a plurality of condensing lenses or refracting prisms continuous in a belt shape on the outer surface of the inner lens unit, and irradiates light from the light source with the inner lens. The reflector type unit is configured to irradiate substantially horizontally in the outer circumferential direction, and the light source is disposed at a substantially focal position of the reflector having a parabolic reflecting surface, and the irradiation light of the light source is directed in a predetermined direction. It can be configured to reflect.
[0009]
The reflecting mirror type unit and the inner lens type unit are configured such that the reflecting mirror type unit is disposed at the center and the inner lens type units are disposed on both sides of the translucent globe. Therefore, the irradiation light to the rear of the reflecting mirror type unit is shielded, and the irradiation light by the parabolic reflecting mirror of the reflecting mirror type unit is increased to the front, so that the visibility to the front of the vehicle is improved. .
[0010]
The cylindrical inner lens constituting the inner lens type unit and the reflecting mirror formed with a parabolic reflecting surface constituting the reflecting mirror type unit can be arranged with each other without changing the position of each light source. It can be configured to be interchangeable.
It is desirable to provide an opening window at the rear part of the reflecting mirror constituting the reflecting mirror unit.
[0011]
According to the above configuration, since the plurality of condensing lenses or refractive prisms formed in a band shape on the outer surface of the inner lens are formed corresponding to the optical axis in the horizontal direction of the light source, irradiation emitted from the light source to the side surface Light is irradiated in a substantially horizontal circumferential direction by these condenser lenses or refractive prisms. Moreover, since the irradiation light reflected by the reflecting mirror of the reflecting mirror type unit is irradiated as the reflected light forward, it becomes an irradiation light whose amount of light is increased in combination with the irradiation light of the light source, and other vehicles Visibility for drivers and pedestrians can be improved.
[0012]
In the translucent globe, a reflector type unit is arranged in the center and inner lens type units are arranged on both sides thereof, and the flashing irradiation light of the light source is emitted through the cylindrical inner lens of the inner lens type unit. The flashing warning light can irradiate in a substantially horizontal circumferential direction with respect to the front and rear and the left-right direction of the flashing warning light, and can also irradiate reflected light forward from the reflecting mirror of the reflecting mirror type unit. As compared with the left and right and the rear, the amount of irradiation light forward can be increased, and the visibility from the front can be improved.
[0013]
In addition, what is configured so that the arrangement of the inner lens type unit and the reflector type unit can be appropriately switched depends on the type and shape of an ambulance, patrol car, fire engine, etc., or the number of warning light units. This makes it possible to change the combination to an optimal unit configuration as a flashing warning light. Further, in the case where an opening window is provided at the rear part of the parabolic reflecting mirror of the reflecting mirror type unit, a part of the blinking irradiation light of the light source can be emitted as irradiation light rearward through this opening window. .
