【Example】

 Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 shows an embodiment of a door opening warning light according to the present invention. In FIG. 1, a door opening warning light 10 includes a case 11, a switch 12 provided on a side surface of the case 11, a left side surface in the drawing so that an operation portion 12a is projected, and an LED mounted on the surface of the case 11. It includes a lamp 13, a drive control circuit 14 for driving the LED lamp 13 contained in the case 11, and a power battery 15 as a drive power source built in the case 11.

As will be described later, the switch 12 is turned off by the operation piece 12a thereof being pressed by being brought into contact with the vehicle side when the door is closed, and is also turned on by being released from the vehicle body side when the door is opened. Thus, it is configured as a push-off switch.

Further, in the illustrated case, the LED lamp 13 is composed of four LEDs arranged side by side in the vertical direction.

The drive control circuit 14 is configured, for example, as shown in FIG. That is, in the drive control circuit 14, the switch 12 is connected in series with the resistor 21 between the drive voltage of the power supply battery 15 and the ground, and two NANDs connected in series to the + side of the resistor 21. The gates 22 and 23, a timer circuit 24 connected to the output of the NAND gate 23 and including a capacitor 24a, a resistor 24b and a diode 24c, and two timer circuits 24 connected in series to the output of the timer circuit 24. The flashing circuit 25 is composed of the NAND gates 25a and 25b, the resistors 25c and 25d, and the capacitor 25e, and the switching transistor 27 whose output is input to the base via the resistor 26. The switching transistor 27 has a collector connected to the LED lamp 13 and an emitter connected to ground. Furthermore, the LED lamp 13 is supplied with a drive voltage from the power supply battery 15.

The door opening warning light 10 according to the present invention is constructed as described above, and when it is used, as shown in FIG. 3, for example, the door opening warning light 10 is provided on the rear edge of the vehicle door 16. The end face 16a is attached to the outside of the door seal 16b. In this case, by attaching a double-sided tape or a magnet plate to the back surface of the case 11 and bringing it into contact with the end surface 16a, it can be easily attached by adhesion or adsorption. The operation piece 12a of the switch 12 is arranged so as to lightly contact the door seal 16b or be slightly apart from the door seal 16b when the door is opened. As a result, the switch 12 is turned off when the door seal 16b is sandwiched between the door seal 16b and the vehicle body side when the door is closed and the switch 12a is pushed by the lateral expansion. There is.

The door opening warning light 10 thus mounted on the vehicle door 16 is positioned between the end surface 16a of the vehicle door 16 and the vehicle body side of the vehicle when the door is closed, and the switch 12 is Since the operation piece 12a is pressed by the door seal 16b, it is in the off state. Therefore, the input of the NAND gate 22 does not reach the threshold value. Therefore, since the L level signal is input to the base of the switching transistor 27, the switching transistor 27 remains off. Thus, the LED lamp 13 does not light up.

When the vehicle door 16 is opened from this state, the door opening warning light 10 is exposed toward the rear of the vehicle. At this time, since the door seal 16b is separated from the operation piece 12a of the switch 12, the operation piece 12a is released from the door seal 16b and is turned on. This causes the input of NAND gate 22 to exceed the threshold. Therefore, an H level signal is output from the NAND gate 23, and this signal is input to the blinking circuit 25 1 via the timer circuit 24. Since the blinking circuit 25 alternately outputs an H level signal and an L level signal at predetermined time intervals, the switching transistor 27 is turned on and off at predetermined time intervals. Thus, the LED lamp 13 is repeatedly turned on and off at predetermined time intervals and is made to blink.

Here, the capacitor 24a of the timer circuit 24 is charged after the output of the NAND gate 23 is inverted to the H level. After charging, the capacitor 24a is discharged through the diode 24c, so that the voltage of the capacitor 24a becomes equal to or lower than the threshold value of the NAND gate 25a after a certain period of time, and the NAND gate 25a is inverted. The output of the NAND gate 25b becomes L level. As a result, the switching transistor 27 is turned off and the LED lamp 13 is turned off. Thus, it is possible to prevent the power supply battery from being consumed due to long-time lighting of the LED lamp 13.

Further, when the vehicle door 16 is closed before the automatic turn-off, the door opening warning light 10 is housed between the vehicle body side of the vehicle and the operation piece 12a of the switch 12 is operated. , Is again pressed by the door seal 16b and switched off. Therefore, the input of the NAND gate 22 is below the threshold value. Therefore, the NAND gates 22 and 23 are inverted and the output of the NAND gate 23 becomes L level. As a result, the output of the NAND gate 25a is held at the H level, the NAND gate 25b is inverted, and the output of the NAND gate 25b becomes the L level, so that the switching transistor 27 is turned off. Thus, the LED lamp 13 is turned off.
