Car light power supply

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light power supply device for a vehicle. In particular, when the driver forgets to turn off the headlight and the fog light in a state in which the vehicle is turned off or in the daytime, the vehicle start detection unit and the external light detection sensor are interlocked. The present invention relates to a light power supply device for a vehicle, which can prevent a battery from being discharged by being able to cut off power of a battery through a power control unit.

In general, the light power supply of the vehicle performs a function of turning on / off the headlights and the headlights of the vehicle by selectively shutting off and applying the battery power by manual operation of the driver.

Referring to FIG. 1, a light power supply of a conventional vehicle that performs the above function is as follows.

1 is a block diagram showing a light power supply of a vehicle according to the prior art.

As shown in FIG. 1, a light power supply apparatus for a vehicle according to the related art includes a battery 10 for converting chemical energy into electrical energy and supplying power at all times, and a switching operation unit for switching and operating a power supply of the battery 10. And a light unit 30 that is turned on / off by receiving the power of the battery 10 by the switching operation of the switching operation unit 20.

In this case, the switching operation unit 20 is the first line (hereinafter referred to as the vehicle street light 31) and the second light (hereinafter referred to as headlight 32) and the third light (hereinafter fog light) of the light unit 30 33), the first switch S1, the second switch S2, and the third switch S3, respectively.

Referring to the operation of the light power supply of the vehicle according to the prior art made of the configuration as follows.

First, when the weather conditions are bad or at night driving, the driver operates the switching operation unit 20 so that the power is supplied from the battery 10 to the light unit 30 so that the vehicle headlight 31 and the headlamp 32 are turned on. To avoid inconvenience when driving the vehicle.

For example, when passing through the fog area when the vehicle is running, the third switch S3 of the switching operation unit 20 is turned on to supply power applied from the battery 10 to the fog light 33 of the light unit 30. By turning on the fog lamp 33 so as to be able to identify his vehicle from the opponent vehicle to ensure safe driving.

In addition, night operation also, by operating the first switch (S1) and the second switch (S2) of the switching operation unit 20 to supply the power applied from the battery 10 to the vehicle headlight (31) of the light (30) ) And the headlights 32, so that the vehicle headlights 31 and the headlights 32 are turned on, so that the vehicle can be identified from the other vehicle, and the driver's view is brightened to allow normal driving. Make sure

By the way, when the driver wants to stop driving the vehicle, the light power supply device of the prior art has to turn off the vehicle and turn off all the switches of the switching operation unit to turn off the vehicle's road and fog lights. When the switch of the operation unit is left in the on state, the battery continuously supplies power to the light unit, which has a big disadvantage of causing battery discharge.

Accordingly, the present invention was created to solve the above problems, and the object of the present invention is that when the driver forgets to turn off the headlights and the fog lights, the vehicle start detection unit and the external light detection sensor are linked to each other through the power control unit. The present invention provides a light power supply device for a vehicle that can automatically prevent the battery from being discharged by turning off the battery.

According to an aspect of the present invention, there is provided a light power supply apparatus for a vehicle, including: a switching operation unit for switching and operating a power source of a battery that converts chemical energy into electrical energy and supplies power at all times; and by switching the switching operation unit. In the light power supply of a vehicle comprising a light unit that is turned on / off by receiving the power of, the power applied from the battery can be cut off when the light unit is turned on for a predetermined time while the vehicle is turned off. And a power control unit configured to generate a power cutoff signal so as to receive a power cutoff signal of the vehicle start detection unit and to cut power supplied from the battery to the light unit.

In addition to the above configuration, the external lighting detection for applying a power off signal to the power control unit to cut off the power of the battery when the light unit is turned on for a predetermined time in a state where the light intensity around the vehicle is greater than the reference value It is preferable to further comprise a sensor.

EXAMPLE

Hereinafter, a preferred embodiment of a light power supply device for a vehicle according to the present invention will be described with reference to FIG. 2.

FIG. 2 is a block diagram showing a light power supply device for a vehicle according to the present invention, and the same name and the same reference numeral will be used for a configuration having the same function as a conventional configuration.

As shown in FIG. 2, a light power supply device for a vehicle according to the present invention includes a battery 10 for converting chemical energy into electrical energy and supplying power at all times, and a switching operation unit for switching and operating a power supply of the battery 10. 20, a light unit 30 that is turned on / off by receiving power of the battery 10 by switching of the switching operation unit 20, and the light unit 30 is turned off when the vehicle is turned off. When the power is turned on for a predetermined time or more, the vehicle start detection unit 50 and the vehicle start detection unit 50 may generate a power cutoff signal to cut off the power applied from the battery 10. And a power control unit 40 which cuts off the power supplied from the battery 10 to the light unit 30.
