The breaker warning light 10 includes a light source 4 provided in a light-transmitting window 31 provided in a part of a light-shielding horizontally long body 3 to form a light-emitting unit 1. Light is emitted and the presence of a blocking bar is urged. The translucent window 31 is formed by a transparent cover, and four light sources 4 as light emitting diodes are aligned in a horizontal line in the window 31, and light from the light source 4 directly from the window 31. As a result, the light emitting section 1 is made horizontally long. Further, solar cells 5 are arranged between the light sources 4 in the window 31 so that electric power is generated by sunlight incident from the window 31, and the generated electric power is stored in the main body 3. The electricity is stored in the electricity storage means 6 which is a lead storage battery.

  Here, in order to ensure safety, the light emitting unit 1 needs to have a visibility of 100 m or more so that any vehicle can be stopped with a margin even under a lighting lamp. Since a sufficient luminance is required, a high-intensity light-emitting diode having a cannonball shape and a small viewing angle is used, and the light from the light source 4 is directly emitted from the window 31 in order to emit the light from the light source 4 without waste. In addition, the light source 4 uses a red light emitting diode to flash red light as a warning color. Moreover, the light emission part 1 arrange | positions the several light source 4 in a straight line, and makes it long horizontally, combined with being the rod-shaped body by which the interruption | blocking bar was extended, the visibility at the time of attaching to the interruption | blocking bar improved. It is made to be able to.

  In addition, since the solar cells 5 are arranged between the light sources 4, the space in the window portion 31 can be effectively utilized while arranging the light sources 4 at intervals, and sunlight is supplied to the solar cells 5. It is not necessary to provide a separate window portion 31 for introduction, and it is possible to perform the process by a simple process for providing a solar cell.

  FIG. 2 is a bottom view of the circuit breaker warning light 10. A part of the window 31 is extended to the lower surface of the main body 3 to form a sensor window 32, the brightness sensor 2 as a photosensor is provided in the sensor window 32, and light from the outside world is transmitted to the sensor window. The brightness sensor 2 can sense the brightness of the surroundings by passing through the part 32. On the back side of the main body 3, a mounting plate portion 71 is provided so as to project along the length direction of the main body 3, and a band mounting hole 72 for inserting a band is provided in the mounting plate portion 71.

In addition to the above-described configuration, the main body 3 further includes a control unit 8 and an inclination sensor 9. The four light sources 4 constituting the light emitting unit 1 are electrically connected to the control unit 8, and the brightness sensor 2 connected to the control unit 8 continuously or intermittently measures the ambient illuminance. 8, when the illuminance falls below the threshold value, it is determined that the night is night, and the control unit 8 supplies the power from the power storage means 6 to the light source 1. In the present embodiment, a tilt sensor 9 is further connected to the control unit 8 so that the illuminance detected by the brightness sensor 2 is less than or equal to a threshold value, and the tilt detected by the tilt sensor 9 is greater than or equal to the threshold value. Only when this occurs, power is supplied to the light source 4. Here, the inclination exceeding the threshold value of the inclination sensor 9 means that the blocking bar is substantially vertical when it is not necessary to block the vehicle, and is substantially horizontal when the vehicle needs to be blocked. Needless to say, it is particularly necessary when the vehicle needs to be shut off, and when the breaker warning light 10 is mounted so that its length is in line with the extending direction of the shut-off bar. Indicates the inclination when the length direction of the warning light 10 for the circuit breaker gradually becomes closer to the horizontal from the vertical and inclines near the front, and is further inclined in the horizontal direction. is there. Such a threshold may be set so that the blocking bar is inclined substantially the same as the horizontal, but if the blocking bar is inclined at about 30 ° to 60 ° with respect to the horizontal, the blocking bar is set as the threshold. The breaker warning light 10 can be caused to emit light from the state where the bar is about to fall, and the alerting about the fact that the bar is descending can be performed together with the presence of the bar. If the blocking bar is less than 30 ° with respect to the horizontal, the blocking bar is almost lowered, and if it exceeds 60 °, a malfunction may occur when the blocking bar is pushed by wind pressure or the like. The tilt sensor 9 may be an appropriate sensor such as a small magnet moving type, a Hall IC type, or a servo type as long as it can detect the tilt along at least the direction in which the blocking bar is raised and lowered.
