Description

 Car light induction flashing warning device  

The present invention relates to the technical field of bicycle warning lights, and more particularly to an innovative invention of a lamp-sensing flashing warning device capable of controlling the warning flashing of the corresponding approaching speed of the vehicle to alert the driver to maintain a safe distance.

Generally, bicycles are provided with warning lights for warning to the front and rear or the side of the vehicle to ensure the safety of driving at night. In the control design of the traditional warning lights, it is roughly a manually controlled switch controlled by the rider of the bicycle. The lights form different modes such as full light, half light, flicker and off; however, this is controlled by the bicycle rider in a manually controlled manner. If the rider forgets to open, the warning light is made useless, and the self is exposed to danger. Driving environment; and the rider's own operation not only causes inconvenience in use, but also easily causes distraction when riding, and increases the risk of driving; in addition, today's traffic is complicated, and the bicycle is slow because of its own speed. In a complicated traffic environment, it is relatively weak. If it is impossible to send more clear and clear messages through warning lights, it will probably be in the complicated car environment. Recently, relevant operators have also introduced improved bicycle warning lights for the aforementioned traditional bicycles. structure.

For example, the "Improved Structure of Bicycle Warning Lights" of the Republic of China Bulletin No. 514059, whose structure is as described in its abstract: especially by bright resistors, vibration switches and other electronic components, when the light is dim and the bicycle is riding, Light-Emitting Diode (English: Light-Emitting Diode, abbreviated as LED) produces a flashing effect, reminding the distant car to notice early and improve the safety of cycling. In addition, when the light is clear and clear, it is compatible with the built-in memory. Body, and when the bicycle is no longer riding over the memory time setting (2~3 minutes), the whole set of warning lights will be turned off, and no light flashing will occur, so there is no need for the whole use. Frequently, the action of the switch is made to achieve a more user-friendly function.

In addition, as for the "Solar Bicycle Warning Light" of the Republic of China Announcement No. M274303, its structure is as follows: it is mainly composed of a casing, a circuit board and a mating seat, and the casing is previously provided with a solar panel. The solar light energy is absorbed and converted into electric energy through a circuit board disposed on the mating socket for storage of the battery. The battery is placed on the battery holder on one side of the mating socket, so that the cover can be easily replaced after being movable. When the bicycle is walking in a dim light source, the CPU disposed on the circuit board can provide a light-emitting diode through the battery discharge process by receiving the signal of the photoresistor and the vibration switch, and when the light becomes bright or When the vehicle is stationary for more than the preset time, the warning light will be automatically turned off, making the warning light more user-friendly.

However, as described above, the two conventional patented structures have a light-sparking effect on the light-emitting diode (warning light) when the light is dim and the bicycle is riding, by means of a photoresistor and a vibration (vibration) switch. Remind the distant car to notice early; however, because the vibration switches of the two prior patents can only control the light-emitting diode (warning light) to generate a simple warning flash, and because of the warning of the prior patent case The flash does not correspond to the different changes of the relative speed of the incoming car, and it is impossible to provide the car driving near the side of the car to judge the speed through the warning flash. In the relatively complicated current traffic environment, it is still easy to misjudge the two cars because of the driving. The danger caused by approaching speed is the biggest drawback.

Therefore, how to make the warning flash issued by the above-mentioned pre-citation structure cannot provide the speed of the approaching driving evaluation of the bicycle on the side of the bicycle, and the speed of approaching the two vehicles, and the innovation and improvement due to the danger caused by misjudgment is the case. The difficulty point to be solved.

The main object of the present invention is to provide a vehicle lamp induction flicker warning device, which can accurately and accurately determine the speed of the approaching speed of the vehicle and the change of the brightness of the incoming vehicle light, so that the main controller can cross-compare and judge. The control light-emitting unit can emit the speed change of the warning flashing corresponding to the approach speed of the vehicle, and provides the driver to accurately determine the relative speed of the two vehicles while maintaining a safe distance, and achieves better safety and safety benefits.

In order to achieve the above object and effect, the vehicle lamp induction flashing warning device comprises a vehicle lamp, a speed sensor, a light collecting unit, a pulse width modulation unit and a main controller, wherein: the lamp is provided A concave curved reflector cup at the front end and an illumination unit at the inner wall of the rear end of the reflective cup.

The light collecting unit is disposed on the vehicle lamp and electrically connected to the main controller, and the light collecting unit is directed toward the direction in which the vehicle lamp is projected and can receive the brightness of the headlight.

The pulse width modulation unit is electrically connected to the light collecting unit and the light emitting unit, and the pulse width modulation unit has an output current of 0 when the light collecting unit receives the brightness of the vehicle light, that is, the light emitting unit does not emit light, and thus can be accurate The brightness of the car lights is measured.

One or both, and the main controller outputs a control signal to the pulse width modulation unit, and the pulse width modulation unit adjusts the speed of the blinking speed of the corresponding vehicle approaching speed of the lighting unit.
