External auto flasher

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic lighting system for external lights, and more particularly, to an automatic lighting system for external lights that automatically controls the external lights according to ambient brightness and a predetermined time.

FIG. 1 is a block diagram for explaining a conventional external automatic lighting device, which is composed of a lamp 4, an illuminance detection unit 10, and a switching unit 2, as shown.

Referring to the conventional technology configured as described above, the illuminance detection unit 10 is constituted by an optical sensor 4 to detect a change in illuminance according to ambient brightness, and generate an illuminance detection signal when the detected illuminance is less than a predetermined value. The signal is applied to the switching unit 2.

The switching unit 2 is switched in response to the detection signal, and forms a power supply passage to supply commercial power to the lamp 4 coupled between the power supply line pairs R and T. As a result, the lamp 4 is turned on.

In this way, when the magnitude of the illuminance detected in the state where the lamp 4 is turned on again becomes a predetermined value or more, the switching unit 2 cuts off the power supply passage in response to the detection signal of the illuminance detection unit 10. As a result, the lamp 4 is turned off.

FIG. 2 is a view illustrating an outline of an illuminance detection unit used in a conventional external auto lighting device, and includes a case 6 and a plurality of leads 10 exposed to one side of the outside of the case 6 to receive power. And a sensor unit 8 in which a light receiving unit is exposed on one side of the case 6 to detect a change in illuminance.

As described above, the conventional automatic lighting apparatus for external lights turns on and off the lights according to the degree of light reception, and the lighting of the lights is frequently generated due to the low light and malfunction of the light sensor, thereby causing unnecessary power loss. Is generated.

It is an object of the present invention to solve the above problems is to provide an external lighting automatic lighting device that can prevent unnecessary power waste by controlling the external light by a predetermined time as well as a change in the illuminance.

In order to achieve the above object, the apparatus of the present invention is an external lamp automatic lighting device having a lamp, the illumination intensity detecting unit for detecting the intensity of the illuminance and outputting a detection signal when the detected illuminance is less than a predetermined value; A timer unit counting a predetermined time and outputting a counting signal; And a switching unit which is switched when the detection signal from the illuminance detection unit and the counting signal of the timer unit are simultaneously input to form a power supply passage in the lamp.

Hereinafter, the technology of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a block diagram illustrating an external lamp automatic lighting apparatus according to the present invention. As illustrated, in the external lamp automatic lighting apparatus equipped with a lamp, the intensity of illuminance is detected and the detected illuminance is less than or equal to a predetermined value. The illuminance detection unit 20 for outputting the detection signal, the timer unit 22 for counting a predetermined time and outputting a counting signal, the detection signal from the illuminance detection unit 20 and the counting signal from the timer unit 22 It is composed of a switching section 24 which forms a power supply passage so that when switched at the same time, the lamp 26 can be turned on.

The overall operation of the apparatus of the present invention configured as described above is as follows.

According to the exemplary embodiment of the present invention, the illuminance detecting unit 20 is configured as an optical sensor and detects illuminance according to ambient brightness, generates an illuminance detection signal when the detected illuminance is less than a predetermined value, and converts the detection signal into a switching unit ( 24).

According to an exemplary embodiment of the present invention, the timer unit 22 may have a predetermined time, and perform a counting operation for a predetermined time, and generate a counting signal when the counting operation is completed to the switching unit 24. Is authorized.

According to the exemplary embodiment of the present invention, since the sensor switch S1 and the timer switch S2 are logically AND coupled to the switching unit 24, the switching unit 24 may be connected to the detection signal from the illuminance detection unit 20. When the detection signals from the timer unit 22 are applied simultaneously, a switching operation is performed, and a power supply passage is formed to supply commercial power to the lamp 26 coupled between the power supply line pairs R and T. do. As a result, the lamp 4 is turned on.

As described above, in response to the intensity of the illuminance detected while the lamp 26 is turned on exceeds a predetermined value or when the timer unit 22 resumes the counting operation, the switching unit 2 performs the switching operation. Stop and cut off the power supply passage. As a result, the lamp 26 is turned off.

Figure 4 is a view showing the external appearance of the sensor unit used in the automatic external lighting device according to the present invention, a case 40, a plurality of leads are drawn to one side of the outside of the case 40 to receive power ( 44, a sensor 42 having a light receiving portion exposed on one side of the case 6 to detect illuminance, and a clock portion 46 for indicating a preset time.

Therefore, in the present invention, by turning off the external light by a predetermined time as well as the intensity of illuminance, there is an effect that can prevent unnecessary waste of power.
