LED threat display device

Abstract

To provide an LED warning display device that automatically controls the blinking pattern and brightness of an LED. [Solution] The LED warning display device of this invention flashes multiple LEDs when the vehicle is locked and turns them off when the vehicle is unlocked, not only indicating to third parties that the vehicle is locked and acting as a theft deterrent, but also equipped with at least one of the vehicle's battery voltage detection circuit, light sensor, and acceleration sensor, and controls the LED flashing pattern and brightness according to the detection results of each, changing its operation according to the environment and vehicle condition.

Description

[Technical Field]

[0001] This invention relates to an LED warning display device that flashes multiple LEDs to deter vehicle theft. In particular, it relates to a technology that effectively deters and warns by changing the flashing pattern depending on the environment and the condition of the vehicle. [Background technology]

[0002] A conventional device of this type is known to have multiple LEDs that flash when the vehicle is locked and turn off when the vehicle is unlocked, in order to indicate to third parties that the vehicle is locked and to act as a deterrent against theft. Summary of the Invention [Problem to be solved by the invention]

[0003] However, in conventional devices, the LED simply flashes, and the flashing pattern or brightness does not change depending on the ambient light or the vehicle's condition (battery voltage, impact, etc.), which has led to issues with practicality and insufficient deterrent effect. [Means for solving the problem]

[0004] In order to solve the above problem, the present invention is an LED warning display device that is equipped with at least one of a vehicle's battery voltage detection circuit, a light sensor, and an acceleration sensor, and automatically controls the LED's flashing pattern and brightness according to the detection results of each. [Effects of the Invention]

[0005] If the LED warning indicator of the present invention is equipped with a battery voltage detection circuit, when the battery voltage drops below a predetermined value while the vehicle is locked, the LED will flash a specific pattern indicating a low voltage warning to the owner, thereby preventing the battery from completely discharging and facilitating power management for the vehicle.

[0006] Furthermore, if a light sensor is installed, it can detect the brightness of the surrounding area and automatically adjust the brightness and flashing pattern of the LED depending on whether it is day or night. This makes it possible to increase visibility during the day and reduce glare at night while also reducing power consumption.

[0007] Furthermore, if the vehicle is equipped with an acceleration sensor, it can detect an impact to the vehicle and display a threatening flashing pattern that is different from the normal one, thereby alerting third parties to the abnormality and enhancing the deterrent effect against theft. Also, when the owner returns to the vehicle, the LED flashing pattern will let them know that an abnormality has occurred while the vehicle was locked, allowing them to quickly check whether there is an abnormality or not.
