In addition, it is formed in a block unit and assembled in the corridor in the building and by detecting the power failure or fire by the photoelectric sensor to guide the emergency escape, there is an effect that can prevent the safety accident in advance.

Furthermore, there is an effect that the LED unit can be driven by the charged power by charging the power by photoelectric conversion of sunlight without supply of external power.

1 is a schematic configuration diagram of a lighting device for a night guide according to a preferred embodiment of the present invention.
FIG. 2 is a cross-sectional view of the lighting apparatus for night guide of FIG. 1.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object will be described in detail.

1 is a schematic configuration diagram of a night guide lighting device according to a preferred embodiment of the present invention, Figure 2 is a cross-sectional configuration diagram of the night guide lighting device of FIG.

1 and 2, the nighttime guide lighting device 100 according to the present invention includes a frame 110, an LED unit 120, a photoconductive sensor 130, a control unit, and a light guide plate 150. ) And a power supply unit.

As shown in FIG. 1, the frame 110 is formed of a block unit having a cube shape having an internal space formed therein. Here, the frame 110 may be made of a synthetic resin, and a fastening part (not shown) may be formed on the side of the frame 110 to be continuously coupled and fixed with other neighboring frames (not shown). That is, a plurality of frames formed of block units may be assembled in a predetermined arrangement by the fastening unit and installed in an emergency evacuation path of a sidewalk or a corridor where pedestrians pass.

The light emitting diode (LED) unit 120 includes at least one pair of LED units 121 fixedly formed inside the frame 110, for example, against an internal space.

Here, the LED unit 121 may be made of a white LED. That is, the white LED may implement a white LED by combining a fluorescent material to a blue LED or a purple LED chip, or may implement a white LED by combining two LEDs having complementary relations with each other. On the other hand, white LEDs can be manufactured in a very small size, consume less power, have a semi-permanent life, have a fast response time because there is no preheating time, emit no harmful waves of ultraviolet rays, and do not use mercury and discharge gas. It is an environmentally friendly light source.

The photoconductive sensor 130 senses the amount of light from the surrounding environment. That is, the photoconductive sensor 130 may be formed of a CdS (cadmium sulfide) sensor having a property that the electrical resistance decreases when the amount of incident light increases and the electrical resistance increases when the amount of incident light decreases. Accordingly, the photoconductive sensor 130 detects a night time, a power failure, or a fire time to turn on the LED unit 120 to guide the guidance to brighten the view of the pedestrian, and to guide the emergency evacuation of the corridor in the building. Safety accidents can be prevented beforehand.

The controller (not shown) controls the on-off of the LED unit 120 by the amount of light detected by the photoconductive sensor 130. That is, the control unit turns on the LED unit 120 when the amount of light detected by the photoconductive sensor 130 is equal to or less than a preset reference light amount, for example, when the corridor in the building becomes dark due to a night or a power failure or fire, For example, the LED unit 120 is turned off during the day or when the corridor in the building becomes bright.

Here, although not shown in detail, the control unit compares the voltage input from the photoconductive sensor 130 according to the reference voltage and the amount of light, the op-amp (OP) which is a comparator for outputting a control signal for turning on and off the LED unit 120 -AMP).

The light guide plate 150 is formed on the upper portion of the frame 110, is made of a transparent material, is formed between the opposing LED portions 120, and guides light emitted from the LED portions 120. To illuminate the exterior environment, such as sidewalks or hallways. On the other hand, the light guide plate 150 may be made of acrylic (arcylic) or tempered glass that is a synthetic resin, and directly accommodates the load of the pedestrian, it may be made of a material having sufficient strength and tensile force.

Here, as shown in FIG. 2, the light guide plate 150 is formed on the upper portion of the frame 110 so as to be exposed to the external environment, that is, irradiated from the LED unit 120 formed opposite to both sides of the light guide plate 150. The light is formed on the upper portion of the frame 110 to be irradiated to the outside. In addition, the LED unit 120 is formed to be spaced apart at a predetermined distance from both sides of the light guide plate 150 so that the irradiated light is smoothly incident to the light guide plate 150.

The power supply unit is inserted into and fixed to a lower portion of the light guide plate 150, for example, the internal space of the frame 110, and provides a photovoltaic solar panel 161 for photoelectric transformation, and a photoelectric conversion power supply from the solar panel 161. The charged and charged power may be provided to the LED unit 120 and the controller to drive the LED unit 120 and the controller 162 to drive the controller, respectively. Here, the solar panel 161 may be formed adjacent to the upper portion of the frame 110 or the lower portion of the light guide plate 150 to efficiently receive the solar light incident from the outside. Therefore, without supplying external power, the solar panel 161 photoelectrically converts solar light to charge the power to the charger 162 so that the LED unit 120 may be opened even in an emergency, for example, in case of power failure or fire by the charged power. Can be driven on and off.

Meanwhile, the power supply unit may drive the LED unit 120 and the control unit with power supplied from the solar panel 161, but may also stably drive the LED unit 120 and the control unit by external power.

Meanwhile, the LED unit 120, the photoconductive sensor 130, the control unit, and the light guide plate 150 are fixedly formed in the internal space of the frame 110, respectively, and the lighting device 100 for night guide is independent. It may be formed as a unit.

Although not specifically illustrated, the LED unit 120, the photoconductive sensor 130, the control unit, and a wire electrically connecting the power supply unit may be configured in the form of a printed circuit board (PCB) or a flexible cable. have.

Therefore, according to the night guide lighting device as described above, by forming in a block unit assembly and installed in the sidewalk, it is possible to perform the role of night lighting and to ensure the stability of the pedestrian during the night walking to ensure stability, The photoelectric sensor 130 detects a power failure or a fire and guides an emergency evacuation route, thereby preventing a safety accident in advance, and photoelectrically converts solar power without supplying external power. The LED unit 120 may be driven by the charged power.
