The present invention relates to a lighting method for a cultivator safety lamp and a cultivator safety lamp to which the lighting method is applied, and more particularly, a self-generating structure or a function is provided, which does not require supply of an external current, and the blinking state is measured by measuring the amount of current. It relates to a lighting method of a cultivator safety lamp configured to be controlled and to ensure the simplification of structure and operation stability, and a cultivator safety lamp to which the method is applied.

In general, tillage is mainly used for agricultural work in rural areas. Depending on the mounting and the usage of the working machine, the traction type for simply attaching and pulling the working machine to the rear and the working type are roughly classified into a driving type for operating the power of the tiller.

In recent years, such a cultivator is mainly used as a traction / drive combined type capable of performing both traction and driving operations.

As the cultivator is manufactured for the purpose of performing agricultural work, the driving speed is not only significantly lower than that of general vehicles, but the frequency of road driving is high, but the safety device is insufficient, which accounts for 90% of the cultivator traffic accident. In particular, there is a problem that the night accident rate is high.

Conventionally, in order to solve such a problem, a luminous reflector, luminous paint, and a low speed vehicle display panel are attached to one surface of the tiller, but other vehicles do not easily identify them. Although the indicator is attached and used, this also has a disadvantage in that it is not easy to identify a tiller running at a low speed in a general vehicle traveling at a high speed.

In other words, rural roads are usually narrow lanes of one-way lanes and are not straight, and are curved. There is a problem.

On the other hand, in order to solve these problems, the Republic of Korea Utility Model Publication No. 208756 has proposed a taillight and alarm device of the tiller trailer that automatically charges the current through the solar battery, the Republic of Korea Utility Model Publication No. 357593 In the arc, there has been proposed a night safety tail lamp provided with an optical sensor and a vibration sensor so that the light emitting unit is automatically turned on without a switch operation.

However, in the case of the former, there is an advantage in that a self-generating structure is provided so that a separate charging of the battery is not required. However, the structure is not automatically turned on according to the surrounding environment. Therefore, the user must turn on the switch by manual operation. Since the hassle is generated, and wiring for positioning the separate switch to the driver's seat is required, the hassle due to the wiring is formed and the wiring may be physically damaged during the later use process.

In particular, when the user does not operate the switch to turn on the light, or the battery is exhausted by being left in the lighted state, it is difficult to perform the original function of the safety light.

In the latter case, an optical sensor is provided, and lighting is made according to the ambient light and whether the cultivator is driven. However, the convenience of use can be facilitated, but since the self-power generation structure is not provided, periodic replacement of the battery is required.

In particular, in the latter case, since an optical sensor for detecting ambient illuminance is inevitably provided, the additional cost of additional installation of the optical sensor increases, and when the optical sensor is covered by the loaded article, the optical sensor Since the instantaneous amount of light is sensed, when a strong light such as a vehicle's light is instantaneously ignited by the ambient illuminance, there is a possibility that the safety light is not properly turned on even at night.

An object of the present invention devised to solve the above problems is that the self-generating structure or function is provided, so that the supply of external current is not necessary, and the blinking state is controlled by measuring the amount of current generated through the self-generating unit, The present invention provides a method of lighting a cultivator safety lamp to simplify the structure and ensure operational stability, and a cultivator safety lamp to which the method is applied.

When the amount of vibration detected by the vibration detecting unit 50 is greater than the reference current stored in the memory 41, the current charged in the battery 30 is supplied to the light emitting unit 60 (S 30). The lighting of the light emitting unit S 40 is implemented.

In addition, in the matching process of the vibration amount and the current amount through the microcomputer 40 (S 20), any one of the amount of current generated through the self-power generation unit 20 and the amount of vibration detected by the vibration detection unit 50 is stored in memory. If less than the amount of vibration and current previously stored in the 41, the current charged in the battery 30 is blocked by the microcomputer 40 (S 30 ′), and the light emitting unit 60 is in a blinking state (S 40 ′). ).
