Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear light mounted on a bicycle or the like.

[0002]

2. Description of the Related Art Bicycle tails include those equipped with reflectors as warning devices, those attached with reflective tapes, or those coated with luminous paint. These are used as tail lights for children's bicycles around 1965. There was a light bulb that was installed with multiple light bulbs and turned on from the left to the right or from the right to the left, but the dry batteries used as the power source are exhausted. The product was discontinued immediately because the contacts for switching the lighting sequentially are easily damaged. After that, there are some things that use reflective plates, reflective tape, or luminous paint,
No one is equipped with a new warning device.

[0003]

Conventionally, a reflector, a reflection tape, a luminescent paint, etc. have been generally used on the tail of a bicycle, but all of them receive light from a following vehicle or the like. Only a part of the light is a reflected light and barely indicates the running position, and there is no one that lights up and displays a brake light, a night running light, a turn signal light, etc., which is mounted on the tail of the bicycle. Therefore, there is an extremely large number of cases in which damage is caused by the following vehicle, and an object of the present invention is to provide a warning device for preventing such damage in advance.

[0004]

According to the present invention, in order to prevent such disasters, a plurality of light emitting diodes which emit visible light such as red, green and yellow are used for each color. Each device is fitted to the fitting plate, and connected to the lighting blinking circuit, power supply and each switch with a cord, and a device that lights up and displays direction indication etc. for each color while braking, running at night, etc. It was solved by installing equipment.

[0005]

Function: The light emitting diode 4 emitting red visible light is fitted in the central portion of the lower side of the light emitting diode fitting plate 1.
Has an effect of indicating that braking is being performed by lighting and blinking, and the brake light switch 14 has an effect of making the current conductive or non-conductive.

The light-emitting diodes 3 emitting green visible light, which are fitted on both outer sides of the light-emitting diodes 4 emitting red visible light, have the function of indicating that the vehicle is traveling at night by turning on the lights. Has the effect of making the current conductive or non-conductive.

The light emitting diode 2 emitting yellow visible light, which is fitted on both outer sides of the light emitting diode 3 emitting green visible light, turns left by blinking.
Further, the light emitting diode 2a that emits yellow visible light has the effect of displaying that the LED turns right by turning on and off, and the left indicator light switch 11 and the right indicator light switch 12 conduct their respective currents. Alternatively, it has a function of making it non-conductive.
