Description

  The present invention is a construction site or event, etc., for traffic control of automobiles and passers-by, lighting lights for nighttime accidents and security operations, etc., or emergency lights used when carrying in an automobile and encountering an accident The present invention relates to a portable induction signal lamp used as

  Conventionally used portable guidance signal lamps have an elongated cylindrical light emitting surface, and only red radiation is generally emitted in all directions.

Conventional portable guidance signal lamps are limited to only red radiation that stops and instructs attention.
For this reason, when organizing the traffic of cars and passers-by, the instructions for stopping and proceeding are issued by changing the way the portable guidance signal lights are swung, etc. There were times when it was difficult to organize traffic.
When it is necessary to illuminate while informing the emergency situation at the accident site at night, an emergency light and a lighting light must be prepared.
In addition, since the conventional portable guidance signal lamp has an elongated cylindrical shape, it cannot be carried in the dashboard of an automobile.
The present invention solves the above problems.

  In order to achieve the above object, the present invention has the following configuration. To shorten the overall length, it consists of a light emitting part with a circular flat light emitting surface on the front and back, and a cylindrical grip that holds the light emitting part. The printed circuit board inside the light emitting part has a red color on the front light emitting surface side. LEDs are arranged at the outer periphery and the center, red LEDs are arranged at the outer periphery and the center, the blue LEDs are alternately arranged with the red LEDs on the outer periphery, and the white LEDs are arranged on the intermediate circumference of the substrate. A portable induction signal lamp characterized by being made.

  The front light-emitting surface is composed of a transparent front plastic plate, the back surface is uneven, the back light-emitting surface is composed of a transparent back plastic plate, the back surface is uneven around the center, and the middle part is circumferential The portable guidance signal lamp is characterized in that the back surface is smooth and the back surface is uneven in the outer periphery.

  A portable induction signal lamp characterized in that the substrate surface of the printed circuit board inside the light emitting unit is covered with a reflector that also serves as a decorative plate.

  The switch arranged in the grip is composed of a red LED switch, a blue LED switch, and a white LED switch. Each switch is waterproofed by a fixed cover, and the color of the fixed cover is the color of the LED corresponding to the switch. A portable induction signal light that is colored the same as

  A portable guidance signal lamp characterized in that the entire length including the grip portion is reduced in size by making the light emitting portion circular.

  Since the emission characteristic of the LED from the flat light emitting surface has a strong directivity in the front direction, the indication direction is good and the indication is accurately recognized from a long distance even in the daytime.

When red light is emitted from the red LEDs on the front and back of the light emitting unit, and the front or back is directed to a car driver or a passerby, it is possible to stop or give instructions. Red radiation is emitted in the opposite direction, but acts as a warning signal because the traffic lane is in a different direction.
When the blue LED on the back of the light emitting unit emits blue light and the back is directed to a car driver or a passerby, it is possible to instruct the advancement. Since the blue radiation is emitted only in one direction from the back side, it is not emitted except in the indicated direction, and can be prevented from being mistakenly recognized.
In conventional signal lights, the instruction content was changed depending on how it was swung, so there was a difference in recognition.In the present invention, however, the instruction content is changed due to a change in color, so it is accurate for car drivers and passers-by. It can be recognized.

  When illumination is necessary at night or the like, it is possible to obtain an illumination light by emitting white light from the white LED on the back surface of the light emitting unit.

  When an automobile emergency light is used, it is possible to notify the surroundings of an emergency by emitting red light from the red LEDs on the front and back of the light emitting unit and swinging it forward, backward, left and right.

  Since the color of the fixed cover of each switch is colored the same as the color of the LED corresponding to the switch, anyone can immediately operate the switch.

  By making the light emitting part circular, the total length including the grip part is reduced in size, so that it can be carried in the dashboard of an automobile.

  Embodiments of the portable signal lamp of the present invention are shown in FIGS. 1, 2, 3, 4, 5, 6, and 7. FIG.

It consists of a light emitting part 1 having a circular flat light emitting surface on the front and back and a cylindrical grip part 2 for holding the light emitting part. The front light emitting surface 8 is a transparent front plastic plate 15 and the back surface is uneven. The rear light emitting surface 9 is a transparent plastic plate 16 for the rear surface, the back surface is uneven at the center, the middle part is circumferentially wide and the back surface is smooth, and the back surface is uneven at the outer periphery. Yes. On the printed circuit board 13 inside the light emitting part, the red LEDs 10 are arranged on the outer peripheral side and the central part on the front light emitting surface side, the red LED 10 on the outer peripheral part and the central part on the rear light emitting surface side, and the blue LED 11 alternately with the red LEDs on the outer peripheral part. The white LED 12 is arranged on the intermediate circumference of the printed circuit board, and is radiated from the place where the back surface of the back side plastic plate 16 of the back light emitting surface is smooth.
The printed circuit board 13 inside the light emitting unit is covered with a reflection plate 14 that also serves as a decorative plate so as not to expose the substrate surface.

By stopping the red LED 10 on the front and the back by the red LED switch 3 disposed on the grip portion 2 and emitting red in the indicated direction, it is possible to stop or recognize the attention accurately. This red radiation can be used as an automobile emergency light.
By turning on the blue LED 11 on the back surface with the blue LED switch 4 and emitting blue in the indicated direction, the progress can be recognized accurately. While the blue LED 11 is lit, the front and back red LEDs 10 and the back white LED 12 are extinguished. The blue LED switch 4 is provided on both sides of the grip portion, and when the portable guidance signal light is held with the right hand or the left hand, it is easy to operate either.
Since the blue radiation is emitted only in one direction from the back side, it is not emitted except in the indicated direction, and can be prevented from being mistakenly recognized.

  When the illumination light is used, the white LED 12 on the back surface is turned on by the white LED switch 5 to emit white light in the target direction. While the white LED 12 is lit, the blue LED 11 is extinguished.

  Each switch is waterproofed by the fixed cover 6, and the color of the fixed cover 6 is colored in the same way as the color of the LED corresponding to the switch.

  The hook 7 is used when the portable guidance signal lamp is fixed to a belt or the like.

  In the grip portion, an LED drive circuit 17 for controlling blinking and lighting of each LED by a switch and a battery housing portion 18 for causing each LED to emit light are housed.

  In the present invention, since the light emitting surface is flat, the red and blue radiations are highly visible in the indicated direction, and when guiding a car or a passerby, the red and blue radiations are used separately to indicate. There is no difference, traffic can be organized smoothly, and it can be accurately recognized from a long distance even in the daytime.

  By emitting white light with good directivity, it can be used as an illumination light when it is necessary to illuminate at the accident site at night or in security work.

  Red light is emitted from the red LEDs on the front and back of the light emitting unit, so if you carry it with an automobile, it becomes an automobile emergency light, and an emergency can be recognized even from a long distance.

  Each switch is waterproofed by a fixed cover, and the color of the fixed cover is colored the same as the color of the LED corresponding to the switch. Therefore, anyone can operate the switch immediately without fail, and it is easy to use.

  By making the light emitting part circular, the total length including the grip part is reduced in size, so it can be carried in the dashboard of an automobile.
