Description

Technical Field

[0001] The present invention relates to a guiding light stick and a guiding light emitting device used for traffic control to guide various vehicles such as automobiles and pedestrians.

Background Art

[0002] Conventional guiding light sticks mainly incorporate single-color light emitting diodes such as red, orange, and blue into the guiding rod tube respectively. For some, a switching switch is provided at the gripping part of the main body to perform operations such as pressing with a finger to switch the lighting and blinking. Also, although guiding light sticks incorporating red and blue light emitting diodes have been developed in the past, they are not currently used due to luminance problems (developed by the present inventor). Furthermore, voice guidance is performed using a speaker, and guiding light sticks inserted into the guiding rod or guiding light sticks with the light emission color linked to the voice have not been developed. Also, a fixing base for swaying the guiding light stick left and right to cope with the temporary absence of a guide has not been developed.

Summary of the Invention

Problems to be Solved by the Invention

[0004] [[ID=4l]]When using a guiding light stick for traffic guidance, for a guiding light stick with two light emission colors of red and green, red indicates "stop" and green indicates "go", so that both the guiding side and the guided side can recognize, and automobiles and pedestrians can be smoothly guided. Furthermore, by linking voice guidance, it can be used as a guiding means for foreign tourists and the weak, which can reduce troubles with pedestrians and the burden on guides. This invention allows for the automatic switching of red and green light emission from a light-emitting diode in accordance with the tilt angle of the guiding stick body. Furthermore, by linking it with voice guidance, it helps prevent misinterpretation by pedestrians and drivers. This invention provides a dual-lamp guided light rod that enables smooth and reliable guidance operation. [Means for solving the problem]

[0005] The guided light-emitting rod according to the present invention comprises a transparent or translucent cylindrical body, a plurality of light-emitting diodes (LEDs) arranged inside the cylindrical body that emit different colors of light, a gripping portion connected to one end of the cylindrical body, a tilt switch for detecting the angle of the gripping portion, and a control device that switches which of the LEDs emits light based on the detection result of the tilt switch. The plurality of LEDs are connected in series, and the control device is configured to change the color of light emission in accordance with the angle of the gripping portion. For example, when the tilt angle of the main body changes upward, a movable contact moves and contacts a fixed contact on either the red or green LED side, causing the LED on the contacting side to emit light. When the tilt angle of the main body changes downward, the movable contact moves in the opposite direction and contacts a fixed contact on the other LED side, causing the other LED to emit light.

[0006] Preferably, the cylindrical body further includes an audio chip and a microspeaker, and the control device causes the audio chip and the microspeaker to output a warning sound when the red light-emitting diode is lit or flashing, and causes the audio chip and the microspeaker to output a warning sound when the blue light-emitting diode is lit or flashing, and the control device adjusts the luminance of the light-emitting diodes or the volume of the sound output by the microspeaker in response to the operation of a switch for specifying the application. More specifically, the light-emitting diodes of this guiding stick use three primary color (RGB) chips to create the light source of the light-emitting diode, and have the function of automatically switching between red (stop) and green (go) in accordance with the tilt angle of the guiding stick without manual operation, and the function of synchronizing the light color and sound. To solve the above problems, this guided light stick has three primary color light-emitting diodes built into a single package inside the light-emitting tube of the main body. The current or PWM (pulse width modulation) applied to each of the RGB channels is controlled (allowing the light color to be freely changed), and it has a function to automatically switch between red (stop) and green (go) according to the angle of the guide stick body, as well as a function to link the light color with sound.

[0007] Preferably, the cylindrical body further includes a partition plate that divides the internal space into two, and the multiple light-emitting diodes are arranged across the two internal spaces divided by the partition plate, and the control device causes the light-emitting diodes of different colors to emit light in the two internal spaces divided by the reflective partition plate. Alternatively, a lens film or white film with a prism-processed surface may be attached to the inner surface of the light-emitting section cylinder of the guided light-emitting rod so that the entire inside of the light-emitting section cylinder emits light uniformly in red or green.

[0008] Preferably, the multiple light-emitting diodes connected in series include alternating red light-emitting diodes and green light-emitting diodes, and the control device flashes only the red light-emitting diodes in one of the internal spaces divided by the partition plate to prompt the driver to stop, while simultaneously flashing only the green light-emitting diodes in the other internal space divided by the partition plate to prompt the schoolchildren to proceed.

[0009] Preferably, when the control device detects that the gripping portion is facing downwards using the tilt switch, it turns off the green light-emitting diode and flashes the red light-emitting diode in the other internal space separated by the partition plate to prompt the child to stop, while simultaneously allowing the red light-emitting diode to continue flashing in the other internal space separated by the partition plate, enabling monitoring of the child.

[0010] The guided light-emitting device according to the present invention comprises a transparent or translucent cylindrical body, a plurality of light-emitting diodes arranged inside the cylindrical body, a gripping portion connected to one end of the cylindrical body, and a fixing base for detachably fixing the gripping portion and for swinging the guided light-emitting rod from side to side. Instead of the guided light-emitting rod, a smoke flare or a flame flares may be fixed to the device. [Effects of the Invention]

[0011] According to this invention, by changing the tilt angle of the guide light stick body, the red and green light emission of the light-emitting diodes is automatically switched, eliminating the need for manual switching. This ensures smooth and reliable guidance of vehicles and pedestrians, and reduces the burden on guides. [Brief explanation of the drawing]

[Figure 5] This diagram illustrates variations in childcare supervision. [Figure 6] This is a diagram illustrating an inductive light-emitting device. [Modes for carrying out the invention]

[0013] The embodiments of the guided light-emitting rod according to the present invention will be described in detail below with reference to the drawings. The embodiments described below are all preferred specific examples of the present invention. The numerical values, components, arrangement positions of components, and connection configurations shown in the following embodiments are examples only and are not intended to limit the present invention. Furthermore, components in the following embodiments that are not described in an independent claim will be described as any component constituting a preferred configuration. Please note that each figure is a schematic diagram and not necessarily a strictly accurate representation. Furthermore, in each figure, substantially identical components are denoted by the same reference numerals, and redundant explanations may be omitted or simplified.

[0014] Figure 1 is a diagram illustrating the outline of the guided light-emitting rod 1 according to an embodiment. Figure 2 shows a cross-section of the guided light-emitting rod 1. Note that the guided light-emitting rod 1 is an example of a guided light-emitting rod according to the present invention. As illustrated in Figures 1 and 2, the guided light rod 1 has a light-emitting cylinder 2, an operating part 3 connected to the light-emitting cylinder 2, and a gripping part 4 connected to the operating part 3.

[0015] The light-emitting unit cylinder 2 is cylindrical and made of transparent acrylic resin, and a lens film 5 or the like with a prism-processed surface is attached to its inner surface. As illustrated in FIG. 1, the internal space of the light-emitting unit cylinder 2 is divided into two by a reflective partition. The light-emitting diode 6 is an aggregate of tape-shaped light-emitting diodes in which a plurality of light-emitting diodes emitting different colors are regularly arranged, and is arranged in a folded manner in the longitudinal direction within the light-emitting unit cylinder 2 and spans the two divided internal spaces.

[0016] The gripping portion 3 is provided with a power switch 8, and an inclination angle switch 9 for automatically switching the light-emitting diode 6 is accommodated within the operation portion 3. The inclination switch 9 is an angle sensor that detects the inclination of the gripping portion 3 (i.e., the inclination of the induction light-emitting rod 1).

[0017] If the induction light-emitting rod main body 1 is inclined upward, the red color of the light-emitting diode 6 is emitted. Also, if the induction light-emitting rod main body 1 is inclined downward, the green color of the light-emitting diode 6 is emitted. A microcomputer board and a battery are accommodated within the gripping portion 11. In the figure, 12 is a battery charging terminal provided on 11.

[0018] FIG. 3 is a diagram illustrating a configuration for controlling the induction light-emitting rod 1. As illustrated in FIG. 3, within the housing of the induction light-emitting rod 1, in addition to the above inclination switch 9, a small microcomputer, a liquid crystal display screen, an audio chip, and a battery control device are provided. The small microcomputer cooperates with the inclination switch 9 to perform light emission control of the light-emitting diode 6 corresponding to the inclination of the induction light-emitting rod 1, and cooperates with the audio chip to perform audio output corresponding to button operations and the inclination of the induction light-emitting rod 1.

[0019] FIG. 4 is a diagram for explaining the buttons provided on the operation portion 3 and the control contents corresponding to these button operations. As illustrated in FIG. 4, the operation portion 3 is provided with a liquid crystal display screen, a mode switching switch, a power switch, an audio switch, a + switch for increasing the volume, and a - switch for decreasing the volume. When the power switch is pressed, the guiding light stick 1 turns on, and "MUTE" and "Battery level %" are displayed on the LCD screen. In this state, the red LED automatically lights up when the guiding light stick 1 is pointed upwards, and the green LED lights up when it is pointed downwards. When the voice switch is pressed while in "MUTE (voice adjustment)" mode, "STOP MODE (operation) 1" will be displayed on the LCD screen, and the light color and voice guidance will be synchronized. If you press the mode switch in this state, the voice guidance will disappear, "MODE2" will be displayed, and the red LED will flash. Pressing the mode switch again switches to MODE3, and the green LED blinks. Pressing the toggle switch again switches to MODE4, and the white LED flashes. Pressing the toggle switch again switches to MODE 5, and the yellow LED flashes in a flowing pattern. Pressing the toggle switch again returns it to MUTE mode, and then it enters an automatic switching state where it switches according to the tilt of the induction light rod 1.

[0020] As described above, with the guiding light stick 1 of this embodiment, when directing traffic, the guide simply turns on the power switch and changes the angle of the light stick body, and the light color automatically switches between red and green according to the tilt angle. This eliminates the need for the conventional fingertip switching operation, allowing the guide to concentrate on guiding vehicles and other vehicles, and enabling smooth and reliable guidance of vehicles and pedestrians. Furthermore, by providing a lens film or the like in the light-emitting tube, the entire inside of the tube will emit light uniformly in red or green, resulting in good visibility and safe guidance. Furthermore, features such as voice guidance and illuminated arrows facilitate the guidance of foreigners and vulnerable individuals, and also have the effect of alleviating anxiety among disaster victims during emergency evacuations.

[0021] (Monitoring schoolchildren using microcontrollers) A modified example of the above embodiment will be described. As illustrated in Figure 5, a reflective partition is provided inside the light-emitting cylinder 2, and multiple COB (chip-on-board) LEDs are installed in series, each assigned an initial number. When the switch is turned ON, the LED on the right flashes red to prompt the vehicle driver to stop. At the same time, the LED on the left side of the partition flashes green in a flowing pattern (the color and flashing pattern can be freely set), providing a function to encourage schoolchildren to proceed. Furthermore, when the main body of the guiding light stick 1 is pointed downwards and towards the schoolchildren, only the blue LED switches to flashing red, prompting the schoolchildren to stop. Note that the LEDs can be arbitrarily selected and given the same function. Furthermore, a voice chip and a micro speaker are inserted inside the light-emitting cylinder 2, and the device has a function that synchronizes the flashing of the red LED with a voice message indicating danger (e.g., stop) and the flashing of the blue LED with a voice message indicating safety (e.g., go).

[0022] (Monitoring school children without a microcontroller) A reflective partition may be provided inside the light-emitting cylinder 2, with one bullet-shaped red LED on one side and one bullet-shaped red and one bullet-shaped green LED on the other side, so that when the main body of the guided light-emitting rod 1 is pointed upwards, the red and green lights illuminate simultaneously, and when it is pointed downwards, the green lights switch to red.

[0023] Figure 6 is an example of an inductive light-emitting device. As illustrated in Figure 6, the guided light-emitting device comprises a guided light-emitting rod 1 and a fixing base 20 for detachably fixing the guided light-emitting rod 1. The fixing base 20 detachably fixes the gripping portion of the guided light-emitting rod 1 and is configured to swing the fixed guided light-emitting rod 1 from side to side like a metronome. Alternatively, a smoke flare or flares may be fixed to the fixing base 20 instead of the guided light-emitting rod 1 and swayed from side to side. [Explanation of symbols]
