The revolving lights 3a and 3b are arranged at both ends of the base 1, and the rear flashing lights 4
The a and 4b are arranged facing rearward between the sirens 2a and 2b and the rotating lights 3a and 3b. The reflectors 5a and 5b are rotating lights 3a and 3b.
This prevents the light of the above and the lights of the rear flashing lights 4a and 4b from being mixed. 6a and 6b indicated by broken lines are transparent gloves that cover the rotating lights 3a and 3b and the rear flashing lights 4a and 4b, and 7 is a perforated cover that covers the sirens 2a and 2b.

Further, below the base 1, a plurality of fixed lights L1, L2, ..., L6 are provided.
Are arranged in a line in the longitudinal direction of the base 1. The fixed lights are partitioned from each other by standing walls 82, ... 86 which are installed upright, and the fixed lights L1 and L6 at both ends are partitioned from the outside by standing walls 81 and 87 at both ends. Further, the lower sides of the standing walls 81, ..., 87 are connected by a protective plate 9c, and the gap between the base 1 and the protective plate 9c is covered by transparent gloves 9a, 9b. Therefore, the fixed lights L1, L
The light of 2, ..., L6 can be projected to the front and the rear as shown by arrows 91 and 92 in FIG. 1 (c). 10a and 10b are fittings for mounting on the roof of the vehicle.

FIG. 2 shows a lighting control circuit for the fixed lights L1, L2, ..., L6. This circuit uses a 5-bit serial / parallel input shift register (M74LS96P).

In the circuit, the selection switches S1, ..., S8 that are interlocked with each other are for switching the flow display and blink display. When connected to terminal 1 as shown in the figure, flow display and when connected to terminal 2 blink display. Becomes

First, a case will be described in which the selection switches S1, ..., S8 are connected to the terminal 1 to display a flow.

The fixed lights L1, L2, ..., L6 are connected to the battery B through switching transistors Tr1 ,. The base of the switching transistor Tr1 is connected through the switch S0 and the resistor R to the serial data input terminal Ds of the shift register 11 to which the “HIGH” level is given, and the bases of the switching transistors Tr2, ... It is connected to 11 output terminals Q0, Q1, Q2, Q3, Q4.
The output terminals Q0, Q1, Q2, Q3, Q4 are connected to the serial data input terminal Ds through the NOR circuit. The load terminal of the shift register 11 is set to "LOW" level, and the direct connection reset input terminal RD
The bars are kept at "HIGH" level. A rectangular voltage is applied to the clock input terminal T from the pulse generation circuit 12, and the parallel data input terminals SD0, ... SD4 are all "LOW".
Being on a level.

The function of the shift register 11 is as shown in Table 1.

In the above Table 1, T0, T1, T2, T3, T4, T5, T6 indicate the rising timing of the rectangular wave given from the pulse generating circuit 12.

The operation of the above circuit will be described. Turn on switch S0,
When the serial data input terminal Ds is set to the “HIGH” level, each time the rectangular wave input from the pulse generation circuit 12 rises thereafter, outputs appear in order at the output terminals Q0, Q1, Q2, Q3, Q4 of the shift register 11. When an output appears on any of the output terminals Q0, Q1, Q2, Q3, Q4, the serial data input terminal Ds through the NOR circuit.
Is "LOW", the bases of the switching transistors Tr1, ..., Tr6 sequentially become "HIGH" level. In this way, the fixed lights L1, L2, ..., L6 are fluidly displayed.

If you want to change the direction of the flow display, select a switch (not shown) to install transistors Tr1 and Tr6, Tr2 and Tr.
5, Tr3 and Tr4 should be exchangeable.

Next, a case where the selection switch is connected to the terminal 2 will be described. In this embodiment, fixed lights L1 and L2, fixed lights L3 and L

Is connected to the base of Tr4, the base of transistor Tr5 is connected to the base of Tr6, and the output terminals Q0,
Connected to Q2 and Q4. Further, the load terminal of the shift register 11 is kept at "HIGH" level and the direct reset input terminal RD (bar) is kept at "LOW" level. A rectangular wave voltage is applied from the pulse generating circuit 12 to the parallel data input terminals SD0 and SD4, and an opposite phase rectangular wave voltage is applied to the parallel data input terminal SD3 through the NOT circuit.

When connected as described above, the function of the shift register 11 is as shown in Table 2.

The operation of the above circuit will be described. Since the selection switches S1, ... S8 are tilted to the side of the terminal 2, the voltage polarities of the parallel data input terminals SD0, SD4 are inverted every time the output of the pulse generation circuit 12 is inverted. Since the voltage NOT circuit of the parallel data input terminal SD3 passes through, the polarity is reversed. Signals having polarities corresponding to the parallel data input terminals SD0, SD2, SD4NI appear at the output terminals Q0, Q2, Q4, respectively. Therefore, the parallel data input terminal
SD0, SD2, SD4 are the bases of transistors Tr1, Tr2, the bases of transistors Tr3, Tr4, the transistors Tr5, T, respectively.
Since it is connected to the base of r6, an alternate blinking state for every two adjacent lamps is realized as shown in FIG.

The case where the flow display and the blink display are performed using the circuit of FIG. 2 has been described above, but it is also possible to continuously light all or part of the fixed lights L1, L2, ..., L6.
At this time, although the circuit is not shown, the circuit may be switched so that only the bases of the transistors Tr1, Tr2, ..., Tr6 corresponding to a desired fixed lamp can be continuously turned on.

In the case of a vehicle equipped with the above-mentioned diffusive warning light, it becomes possible to give a warning to the following vehicle or an oncoming vehicle by blinking while the vehicle is stopped. At this time, the alerting power is more effective than the case of merely continuous lighting.

Further, as shown in FIG. 4, when the vehicle CAR is parked on the side of the road, it is possible to guide the following vehicle by displaying a flow in the direction of arrow A in the figure.

If the flow direction can be changed, for example, when the vehicle stops near the center line of the road, the following vehicle can be guided to the side of the road.

<Effect of Device> As described above, according to the diffused type warning light of the present invention, since the flow display by the fixed light can be performed, the kind of information that can be lighted can be compared with the case of simply continuous lighting. It is possible to display the road direction to pedestrians and vehicles, and to effectively guide pedestrians and vehicles.

Further, if the blinking display can be arbitrarily selected and displayed together with the flow display, it is possible to effectively call the attention.

Further, by making it possible to project the light of the fixed light both to the front and the rear, it is possible to obtain the same warning effect as that of the front even for vehicles and passersby coming from the rear.
