 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. 1 is a sectional view showing an embodiment of a flash type warning lamp according to the present invention, FIG. 2 is a partially cutaway plan view, FIG. 3 is an exploded perspective view, FIG. 4 is a side view, and FIG. It is a front view of a white motorcycle. In these figures, a flash type warning light 10 is fitted with a mounting hole 11 provided in a cowling 4 of a motorcycle 3, and is fixed together by a plurality of setscrews 12 and nuts 13 with a lamp body 14 and a lens 15. A lamp chamber 20 for accommodating the discharge tube 16 and the reflector 17 as a light source is formed by these, and the lighting circuit of the warning lamp 10 is printed and formed in the lamp body 14 as well as the transformer 19. A printed circuit board 18 on which electric components such as a capacitor are mounted is stored.

The lamp body 14 is composed of a back cover 21 and a body 22 inserted and arranged in the back cover 21. The back cover 21 is integrally formed by resin injection molding or the like, and has a box-shaped main body 21a whose upper surface is open, and an oval lens mounting portion 21b provided on the periphery of the opening of the main body 21a. Then, the body 22 is inserted into the main body 21a together with the printed circuit board 18, and is fixed by a plurality of setscrews 23. Fixed portions 24 (FIGS. 1 and 3) for supporting and fixing the lower surface of the corner portion of the printed board 18 are provided at four corners of the inner bottom surface of the main body 21a. The lens mounting portion 21b is formed in a flat plate shape, and an annular groove 25 is formed on the outer periphery of the front surface over the entire circumference, and the opening of the lens 15 is inserted into the annular groove 25 through a packing 26. It is fitted and fixed together with the lens 15 to the cowling 4 by the set screw 12 and the nut 13. Therefore, a pair of screw mounting holes 27a and 27b into which the set screw 12 is inserted are formed at both ends of the lens mounting portion 21b on the long axis side. Further, a cord insertion hole 28 and a ventilation hole 29 are formed in the lens mounting portion 21b so as to be located inside the annular groove 25. A cord 31 is inserted into the cord insertion hole 28 via a bushing 30, an inner end of the cord 31 is connected to an electric circuit of the printed circuit board 18, and an outer end thereof is connected to a power source (motorcycle) through connectors 32a and 32b. 3 battery).

When the lamp chamber 20 is hermetically closed, when the water inside the lamp chamber becomes water droplets and adheres to the inner surface of the lens 15 due to a rapid temperature change, the function of the lamp is significantly reduced. When the temperature inside the lamp chamber rises due to the heat generated when the discharge tube 16 is turned on, the lamp body 14 or the lens 15 is thermally deformed. Therefore, the vent hole 29 is formed in the lens mounting portion 21b so that the inside and the outside of the lamp chamber 20 are communicated with each other, so that generation of water droplets, temperature and pressure fluctuations, etc. are prevented from being reduced. In addition, one end of a tube 33 bent in a U shape or a J shape is connected to the ventilation hole 29 in order to prevent rainwater or the like from entering the lamp chamber 20 through the ventilation hole 29.

The body 22 is formed of resin or the like into a box shape whose lower surface is open, and a vertically elongated U-shaped discharge tube mounting hole 36 is formed on the upper surface thereof, and a holder / reflector mounting portion 37 is projectingly provided. The printed circuit board 18 is fixed to the lower opening by the set screw 23.

The discharge tube 16 is a semi-circular or U-shaped curved glass tube 16a filled with a vapor of metal such as neon or xenon, and a pair of electrodes 16b, 16c provided at both ends of the glass tube 16a. And a trigger wire 38 wound around the peripheral surface of the glass tube 16a, and the pair of electrodes 16b and 16c are inserted into the body 22 through the discharge tube mounting hole 36 and soldered to the electric circuit of the printed circuit board 18. Is connected. The trigger wire 38 is for uniformly applying a high voltage to the entire length of the glass tube 16a, and is wound in a spiral shape over substantially the entire length of the glass tube 16a.

The lens 15 is formed in a dome shape with a resin or glass having a light-transmitting property colored in red, yellow or the like, and is screw-mounted so that the set screw 12 is inserted into both ends of the major axis. A hole 40 and a vertical groove 41 are formed respectively.

The reflector 17 is made of a metal such as aluminum, zinc or stainless steel, and has a groove 42 (FIG. 2) having a semi-elliptical (or semi-circular) cross section at the center of its outer surface. The entire inner surface of the groove 42 forms a parabolic reflection surface 43 by vacuum deposition of aluminum or the like. The glass tube 16a of the discharge tube 16 is inserted and disposed in the groove 42 so as to straddle the reflector 17 and with its axis aligned with the focal point of the reflecting surface 43. The focal point of the reflecting surface 43 is continuous over the entire length of the groove 42.

In this case, the reflector 17 is composed of two reflector pieces 17 A that are formed in two and have the same shape. The reflector piece 17A is composed of a joining piece portion 117a whose one end in the longitudinal direction is formed in a semicircular shape, and a strip-shaped reflector piece portion 117b which is continuously provided on the peripheral edge of the joining piece portion 117a and which is curved in an arc shape. The edge 44 of the piece 117b on the side opposite to the joint piece 117a side is similar to the joint piece 117a and has a larger shape, and the surface of the reflector piece 117b forms a part of a parabolic reflection surface. It is a concave curved surface. The pair of reflector pieces 17A are fixed to the setscrew 46 and the nut 47 with the joining piece portions 117a being back to back on both sides of the holder / reflector mounting portion 37 and closely contacted via the holder 45. As a result, one reflector 17 is formed.

The holder 45, which is interposed between the reflector piece 17A and the holder / reflector mounting portion 37, is formed of a metal plate such as stainless steel into a semicircular shape as shown in FIG. A holding portion 45a that holds the central portion of the tube 16a is formed by bending, and holding portions 45b that hold the end portions of the glass tube 16a are formed at both ends. The holding portions 45a and 45b hold the glass tube 16a so as to contact the trigger wire 38. One of the pair of holders 45 is connected to a terminal 48 via the set screw 46, and the terminal 48 is fitted and held by the set screw 46 and a secondary of the transformer 19 via a cord 49. It is connected to the side winding. Here, although two holders 45 are provided in this embodiment, the number of holders 45 is not limited to this, and one holder may be used if the shape of the holding portion 45a is, for example, Ω.

FIG. 6 is an electric circuit diagram of the discharge tube 16. The switch SW and the trigger capacitor CT are connected between the primary winding 19a of the transformer 19 and the power source, and the trigger wire is connected to the secondary winding 19b. 38 is connected. Further, the discharge tube 16 and the capacitor CM are connected in parallel to the power source. The switch SW is normally held in the OFF state, and when the discharge tube 16 blinks, the switch SW is brought into contact with or separated from the discharge tube 16 at a fast cycle by an electrical or mechanical switch driving means. (For example, the rated input of the discharge tube 16 is 8 W · sec, the used voltage is 284 V, the rated number of flashes is 120 times / min, the input voltage (primary side) of the transformer 19 is 200 V, and the output voltage (secondary side). ) Is 8 to 10 KV.) In such a configuration, if a voltage for lighting the discharge tube is applied between the electrodes (16b, 16c) of the discharge tube 16 and the switch SW is contacted and separated at a fast cycle in this state. Each time, the capacitor CM and the trigger capacitor CT are charged and discharged, and a high voltage is periodically induced in the secondary winding 19b of the transformer 19, and this high voltage is passed through the cord 49 to the holding portion of the holder 45. When added to 45a and 45b, the atoms in the glass tube are excited, ionized, and discharged to emit a flash of light. At this time, since the holding portions 45a and 45b are in contact with the trigger wire 38, the high voltage is evenly applied to the glass tube 16a. Then, this flash light strikes the reflecting surface 43 (FIG. 2) of the reflector 17 and is reflected, and then passes through the lens 15. The blinking period and brightness of the discharge tube 16 can be easily changed by changing the switching time of the switch SW and the applied voltage.

FIG. 7 is a perspective view showing another embodiment of the present invention. In this embodiment, the flash type warning light 2 is incorporated into each of the left and right side surfaces of a rear spoiler 51 installed at the rear portion of the patrol car 50, and an electric circuit diagram is shown in FIG. The configuration of the flash warning lamp 2 itself is the same as that of the above-mentioned embodiment, but the shape of the lens is L-shaped (or U-shaped) in plan view so as to form the same surface as the side surface of the rear spoiler 51. ..

In FIG. 8, 60 is a battery as a power source, 61 is a power switch, 62 is a control unit for the left and right flash type warning lights 2, 63 is an emergency / normal switching switch, and 64 is daytime / nighttime. It is a changeover switch of. The control unit 62 applies the trigger voltage to the noise filter 65, the DC-DC converter 66 that boosts the input voltage to an appropriate voltage value and accumulates it in the capacitor as flash energy, and the trigger wire 38 of the discharge tube 16 at a predetermined cycle. It comprises a trigger control circuit 67, a protection circuit 68 for the control unit 62, a switch 69, etc., and controls blinking of the left and right flash type warning lights 2. Even with such a configuration, the same effect as that of the above embodiment can be obtained.

[0019]

[Effect of the device]

 As described above, since the flash type warning lamp according to the present invention uses the discharge tube as the light source and is configured to discharge the discharge tube intermittently, it is not necessary to rotate the reflector, and the reflector does not rotate. If not, the space inside the lamp chamber can be made small and the driving means therefor is not necessary. Therefore, the warning lamp itself can be made smaller and lighter, and it is suitable to be installed in a white motorcycle. Further, the discharge tube has an effect that the power consumption is smaller than that in the case where the reflector is rotated by the drive motor.
