The central processing unit 11 may have a function of controlling the lighting of the LED module 15 according to a signal transmitted from the detection sensor module 13 while checking the status of each of the devices. Further, the central processing unit 11 may have a function of confirming the state of charge of the battery module 12 and displaying it on the display device 16. [

The apparatus according to the present invention needs to be supplied with power from the battery module 12 while having a lighting function, so that the control of the power supply state of the battery module 12 is required. Thus, the battery module 12 may have a device associated with charging and powering. The battery module 12 may include, for example, a battery cell such as a nickel-cadmium battery, a nickel-hydrogen battery, a lithium ion battery, and a lithium ion polymer battery, but the battery cell is not limited thereto.

1B, the battery module 12 may be connected to an external input terminal, for example, AC 220 V, for charging the battery, and may be connected to the battery module 12 to provide stable charging, The filter unit 121 may be installed.

On the other hand, the control unit 125 may have a function of controlling or monitoring the current (OUT) to be supplied. As such, the battery unit 12 according to the present invention may include a device for charging the battery and for controlling or monitoring the power supply to the LED module 15.

The illumination device according to the present invention can emit light based on a signal transmitted from the detection sensor module 13. [ The detection sensor module 13 may include a light detection sensor 131, a human body detection sensor 132, or a door open / close detection sensor 133. The light sensor 131 may be a device such as a photosensor or an illuminometer that generates a signal for determining whether the LED module 15 is operated by detecting an inflow of external light. The human body detection sensor 132 may be, for example, an infrared sensor or an ultrasonic sensor. The door opening / closing sensor 133 may be an impact sensor or a magnet sensor capable of detecting whether the door is open or closed.

The battery module 12 may have the structure shown in FIG. 1B (B).

Referring to FIG. 1B (b), the protection circuit 121a is for surge protection and overcurrent protection and may include a varistor and a fuse.

On the other hand, a thermal sensor may be used as the human body sensor 132 if the lighting device is used, for example, as an emergency light for outdoor leisure activities.

Various kinds of sensors can be applied to the illumination device according to the present invention, and the present invention is not limited by the kind of the sensor.

The signal detected by the detection sensor module 13 may be converted into an electrical signal and transmitted to the central processing unit 11. The central processing unit 11 controls the switch module 14 according to the signal transmitted from the detection sensor module 13 to determine whether the LED module 15 is operated. The central processing unit 11 may include a comparator. The comparator has a function of determining whether or not the signal transmitted from the detection sensor module 13 corresponds to a predetermined signal. For example, if the duration of the signal transmitted from the ultrasonic sensor provided by the human body sensor 132 is less than 1 second to 2 seconds, for example, and the signal is not detected after this time has elapsed, It is determined that the signal is not a signal and the operation of the LED module 15 is stopped. If the door open / close sensor 131 is kept open for 30 minutes or more, for example, and the signal is not detected by the human body sensor 132, it is determined that the door is opened to an unexpected state. Accordingly, the comparator can stop the operation of the LED module 15. [ In this way, the comparator can have a function of determining the operating condition of the LED module 15. The operating conditions may be pre-determined and embedded in the form of a program in the comparator, and additional operating conditions may be added or existing operating conditions may be changed as needed in various situations.

The manual switch has a function to always operate regardless of the signal transmitted from the detection sensor module 13, for example. The manual switch can be selectively installed and the present invention is not limited by the presence or absence of the manual switch.

The LED module 15 may include a plurality of LED elements. For example, an LED element having a power consumption of 2 to 30 watts may be disposed. The power consumption of the LED module 15 can be adjusted by the central processing unit 11. [ The LED device may be any device known in the art, and the present invention is not limited thereto.

A display device 16 for indicating the state of charge of the battery may be provided in the device according to the present invention. The central processing unit 11 displays the degree of charge of the battery through the display device 16 and may cause, for example, a flashing means or an alarm sound to be generated when charging is required.
