BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle safety light provided with a solar cell as a power supply and indicating the position of the bicycle in a dark place by blinking an LED.

[0002]

2. Description of the Related Art In general, a reflector lamp is used as a bicycle safety light for indicating the position of a bicycle in a dark place.

[0003]

A reflector lamp conventionally mounted on a bicycle requires a light source somewhere, and it is reflected light, so that it does not attract any attention. If you try to positively display the position of the bicycle, for example, by using the battery of the bicycle lamp as the power source and turning on the safety light itself, the battery consumption will be large when parking the bicycle for a long time. Therefore, such a method is not practical. Therefore, it is necessary to solve the problem that the safety light can be actively turned on to inform the surroundings of the bicycle without relying on the reflected light, and that the power can be secured economically. I was

[0004]

Accordingly, the present invention provides a case in which a window is provided on the upper surface and a power supply unit is fixed in a case having an open end face, with a solar cell facing the window, and in front of the end face, The LED connected to the power supply unit is made to protrude, the reflection plate is fitted thereto, and a transparent cover having a front end face formed on the lens is fitted to the window hole and the edge of the end face, and the LED together with the window hole is provided. And the reflector, and this cover is fixed to the case, and connected to the power supply unit to operate the LED.
The present invention provides a bicycle safety light characterized in that a lighting switch for switching between N and OFF is attached to the case so as to enable external operation.

[0005]

The safety light of the present invention constructed as described above is charged mainly by sunlight in the daytime, and the lighting switch is turned off when desired.
By lighting the LED with N, the safety light itself is turned on, and the position of the bicycle can be positively notified to the surroundings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. In the drawing, reference numeral 1 denotes a case having a bottomed horizontal cylindrical shape in which a window hole 2 for lighting is provided on the upper surface and an end face 3 (left hand in FIG. 1) is opened. Power supply unit. The power supply unit 4 is a solar cell 5
A constant voltage circuit, a sunshine discriminating switch circuit, and an oscillation output circuit are provided on the substrate 7 together with the secondary battery 6, and the LED 8 connected to the left end in FIG. 9
Is a cylindrical reflector having an outer diameter equal to the inner diameter of the case 1 and superimposed on the end face 3 of the case 1 to fit the LED 8 therein, and 10 has a front end face (left hand in FIG. 1) formed on the lens 11. A transparent cover that fits into the edge of the window hole 2 and the end face 3 and covers the LED 8 and the reflector 9 together with the window hole 2 and is fixed at the joint surface with the case 1. This is a lighting switch which is fitted in the hole 13 provided in the, and is attached so as to enable operation from outside. The lighting switch 12 is connected to the power supply unit 4 to turn on and off the operation of the LED 8.
Switch to. In addition, the power supply unit 4 charges the secondary battery 6 via the solar battery 5, and automatically blinks the LED 8 via the constant voltage circuit, the sunshine determination switch circuit, and the oscillation output circuit. In the drawing, reference numeral 14 denotes a mounting portion with a screw hole to the bicycle integrally formed on the lower surface of the rear end portion of the case 1.

In the bicycle safety light constructed as described above, when the lighting switch 12 is turned on and the sunshine discriminating switch circuit is turned on, the LED 8 is automatically turned on and off by the operation of the oscillation output circuit. The blinking light of the LED 8 passes through the reflecting plate 9 and the lens 11 provided on the transparent cover 10 and is projected toward the front of the case 1 to inform the surroundings of the position of the bicycle. In addition,
The power supply unit 4 of this embodiment is 30 to 40 outdoors in fine weather.
It is designed to provide about 10 hours of lighting time with a minute charge.

[0008]

As described above, in the safety light of the present invention, the LED is automatically turned on and off via the power supply unit using the solar cell as a power supply, so that the power supply can be used economically and permanently. . In addition, since the lit LED is used as a safety light, the position of the bicycle can be positively displayed,
As well as high safety effect, bicycle enthusiasts can be expected to use it as a new accessory that attracts the attention of the surroundings. There are practical effects as described above.
