Description

Warning lamp for vehicle}

The present invention relates to warning lights for vehicles.

In general, warning lights are used to draw attention or generate alarms in industries, businesses, group residential facilities, etc., and in some fields, the tendency to be mounted on various moving objects, including vehicles, is increasing. In recent years, in keeping with changes in the industrial environment, the number of LED-type warning lights that consume low power has been increasing.

In relation to this, prior patent registration No. 10-1519820 discloses an LED warning light for vehicles. The automotive LED warning light disclosed in the prior patent can improve durability due to vibration in a moving body, is easy to change the light emission pattern in response to the surrounding environment, and has the characteristics of improving assembly and productivity based on a simple structure.

Meanwhile, the conventional warning lights for vehicles were inconvenient in that the user had to turn on the power directly to operate the warning lights, and had to turn the power off directly to stop the operation of the warning lights.

In addition, in rural areas where the surroundings are relatively dark, it is common to install warning lights on agricultural machinery, and if the warning lights do not work while driving agricultural machinery, there is a problem of causing a serious accident.

For example, in rural villages where the elderly make up a relatively large proportion of the population, warning lights for the safety of cultivators, electric wheelchairs, etc. are manually turned off and then driven at night, resulting in many casualties or safety accidents.

Ultimately, in the case where warning lights are provided in operating devices such as cultivators, electric wheelchairs, and agricultural machinery that operate at relatively low speeds and are relatively heavily used by the elderly and the weak, in order to further improve safety, they are operated during the day and night regardless of the user's power on/off operation. Technology is needed to automatically activate warning lights at night.

Hereinafter, the control method of vehicle warning lights will be described in detail with reference to the drawings.

Figure 6 is a flowchart showing a method of controlling warning lights for a vehicle according to an embodiment of the present invention.

Referring to FIG. 6, the control unit 190 detects the illuminance through the illuminance sensor 160 and determines whether the detected illuminance is less than the reference illuminance.

Specifically, the vehicle warning light 100 may be mounted to be exposed to the outside of the vehicle. Therefore, it is possible to determine whether it is daytime or nighttime through the illuminance detected through the illuminance sensor 160 (S1, S2).

If the detected illuminance is less than the standard illuminance, the control unit 190 detects the movement of the vehicle through the vibration detection sensor 170 and the speed detection sensor 180, and operates the LED when the movement of the vehicle is detected.

Specifically, the control unit 190 can detect the tremor and vibration of the vehicle through the vibration detection sensor 170 and the speed and acceleration of the vehicle through the speed detection sensor 180 at night.

And the control unit 190 can determine the movement of the vehicle using the degree of vibration detected through the vibration detection sensor 170 and the speed detected through the speed detection sensor 180.

That is, if the control unit 190 determines that the vehicle is moving at night, it can operate the LED 230 to perform a warning lighting function. The plurality of LEDs 230 may emit light in various ways, such as sequentially and continuously or repeatedly blinking at the same time to provide warning lighting.

Therefore, when driving at night, the LED 230 can be turned on automatically, thereby improving stability and convenience of use (S3, S4, S5).

With the LED 230 in operation, the control unit 190 re-determines whether the detected illuminance is higher than the standard illuminance, and if the detected illuminance is higher than the standard illuminance, stops the operation of the LED.

Specifically, the control unit 190 can turn off the LED 230 during the day while the LED 230 is operating at night. That is, the LED 230 can be automatically turned off when the light changes from night to day while driving, thereby improving economic efficiency and ease of use (S6, S7).

Meanwhile, if the illuminance detected in step S6 is less than the standard illuminance, the control unit 190 determines whether there is no movement of the vehicle, and if there is no movement of the vehicle, determines whether there is vibration of the vehicle. Stops the operation of the LED.

Specifically, the control unit 190 can determine whether there is no movement of the vehicle through the speed sensor 180 and determine whether there is vibration of the vehicle through the vibration sensor 170.

As a result of the determination, if there is still movement or vibration of the vehicle, the control unit 190 maintains the operation of the LED 230.

If there is no movement of the vehicle and no vibration of the vehicle, the control unit 190 determines that driving has ended and stops the operation of the LED 230. That is, when the night driving ends, the LED 230 can be automatically turned off (S8, S9).

Additionally, if the illuminance detected in step S2 is less than the standard illuminance, the control unit 190 determines whether an occupant is present based on the detection result of the human body detection sensor 240, and if it is determined that the occupant is present, the vibration Detects and determines whether the vehicle is moving based on the detection result of the detection sensor 170 and the detection result of the speed detection sensor 180, and at least one of the vibration detection sensor 170 and the speed detection sensor 180 If one is detected to be higher than a preset value, the LED 230 can be controlled to operate.

In other words, detecting the night time has the advantage of first determining whether there are occupants inside the vehicle, and detecting the movement of the vehicle only when there are occupants, allowing a more accurate determination of driving.
